AB  - У науци данас постоји све већи број покушаја бионичког карактера да се креирају системи који опонашају природне механизме и концепте. Њихово увођење у инжењерску праксу даје најчешће добре резултате и омогућава човеку да боље разуме начине који су природни, хармонични и опстају хиљадама година. Облик тела делфина је веома интересантан за проучавање у разним инжењерским гранама у данашњици. Међутим, и међу претечама авијације је још почетком 19. века облик тела делфина представљао инспирацију за могући будући облик трупа летелице.
Савремена истраживања су свој фокус ставила на проучавање механизма пливања делфина, затим структуру његове коже, јер омогућава одржавање ламинарног граничног слоја готово целом дужином тела током кретања кроз воду. Квржице на кожи делфина су веома занимљиве из угла ваздухопловства, јер престављају начин којим се врши индиректна или пасивна контрола граничног слоја. Постоје и многе друге особености које инжењери нису успели да имплементирају у један јединствен систем одједном, али истраживања на ову тему охрабрују за будућност.
У дисертацији је представљена нова фамилија хибридних Делфин аеропрофила. Изворна идеја за развој ове фамилије аеропрофила је проистекла из математичког модела румунског математичара и научника Јосифа Тапосуа. Тапосу је представио модел којим се може конструисати аеропрофил веома специфичног облика, са оштром нападном ивицом, који подсећа на тело делфина у подужном пресеку. Творац овог модела аеропрофила га је назвао новим концептом у аеродинамици. Како би се испитала својства ових аеропрофила за потребе дисертације, конструисани су ″математички Делфин аеропрофили″ или ″оригинални Делфин аеропрофили″, као и њихови геометријски пандани из фамилије стандардних аеропрофила NACA.
Под геометријским панданом се подразумева аеропрофил са истом максималном релативном дебљином, кривином и њиховим положајем. За поређење профила коришћена је CFD анализа базирана на примени RANS система једначина са k – ω SST турбулентним моделом за режиме струјања при Маховим бројевима мањим од М=0.3 Прорачуни су вршени при Рејнолдсовом броју MRe=6.0, за случај стандардне храпавости, који подразумева форсирани рани преображај ламинарног у турбулентни гранични слој. Коришћена је структурирана C – мрежа за прорачуне, а а резултати добијени за сваки NACA аеропрофил су верификовани понаособ поређењем са експерименталним подацима из NACA Rep. 824 и из издања Theory of Wing Sections, Abbott et. al. [1, 2]. За модификацију домена нападне ивице оригиналних Делфин аеропрофила у циљу побољшања њихових аеродинамичких карактеристика, у овој дисертацији су уведене и приказане две иновативне методе: ″метод природне оптимизације″ назван семиелиптични метод, и ″NA - DEL″ геометријски метод оптимизације.
Модификацијама уз помоћ ове две методе је креирано седам хибридних Делфин аеропрофила, који су задржали око 70% задњег домена оригиналних Делфин аеропрофила. Свих седам хибридних аеропрофила су показали боље аеродинамичке карактеристике како у односу на оригиналне Делфин пандане тако и у односу на NACA геометријске пандане. Приказане су упоредне табеле, дијаграми аеродинамичпких коефицијанта и финесе при чему су сва побољшања приказана и процентуално.

Након успешене прорачунске верификације, и експериментално су потврђене боље аеродинамичке особине нове фамилије хибридних Делфин аеророфила на примеру аеропрофила NA - DEL 2415. У универзитетском аеротунелу ″Мирослав Ненадовић″ Машинског факултета Универзитета у Београду под истим условима опструјавања испитани су NACA 2415, оригинални аеропрофил Делфин 2415 и овде приказани нови NA - DEL 2415. Резултати су недвосмислено показали да хибридни профил NA - DEL 2415 поседује боље аеродинамичке карактеристике у односу на друга два испитана аеропрофила. Тиме је потврђена хипотеза и отворен пут да новодобијена фамилија хибридних Делфин аеропрофила нађе примену како на летелицама категорије опште авијације, тако и на беспилотним летелицама.
AB  - In science nowadays, there is an increasing number of bionic attempts to create systems that mimic natural mechanisms and concepts. Their introduction into engineering practice usually gives good results and allows man to better understand ways that are natural, harmonious, and persist for thousands of years. The shape of the dolphin's body is very interesting to study in various engineering branches nowadays. However, among the forerunners of aviation, even at the beginning of the 19th century, the shape of the dolphin's body was an inspiration for the possible future shape of a fuselage of aircraft.
Modern research has focused on the study of the dolphin's swimming mechanisms, the structure of its skin because it enables the maintenance of a laminar boundary layer along almost the entire length of the body during movement through water. The nodules on the dolphin's skin are very interesting from an aeronautical point of view, because they represent a way of indirect or passive control of the boundary layer. There are many other features that engineers have not been able to implement into a single system at once, but research on this topic is encouraging for the future.
This dissertation presents a novel family of hybrid Dolphin airfoils. The original idea for the development of this airfoil family arose from the mathematical model of the Romanian mathematician and scientist Iosif Taposu. Taposu presented a model that can be used to design an airfoil with a very specific shape, with a sharp leading edge, which resembles the body of a dolphin in the longitudinal section. The creator of this airfoil model called it a new concept in aerodynamics. To examine the properties of these airfoils for the dissertation, the ″mathematical Dolphin airfoils″ or ″original Dolphin airfoils″, as well as their geometric counterparts from the family of standard NACA airfoils, were designed.
A geometric counterpart is an airfoil with the same maximum thickness ratio, camber, and its position. CFD analysis based on the application of the RANS system of equations with the k - ω SST turbulent model for flow regimes at Mach numbers lower than M=0.3 was used to compare these airfoils. The calculations were performed at the Reynolds number MRe=6.0, for the case of standard roughness, which implies a forced early transition from laminar to turbulent boundary layer. A structured C - grid was used for calculations, and the results obtained for each NACA airfoil were verified individually by comparison with experimental data from NACA Rep. 824 and Theory of Wing Sections, Abbott et. al. [1, 2]. To modify the domain of the leading edge of the original Dolphin airfoils to improve their aerodynamic characteristics, two innovative methods were introduced and presented in this dissertation: the ″natural optimization method″ called the semielliptic method, and the ″NA - DEL″ geometric optimization method.
Modifications with these two methods resulted in the creation of seven hybrid Dolphin airfoils, which retained about 70% of the rear domain of the original Dolphin airfoils. All seven hybrid airfoils have proved better aerodynamic characteristics both in relation to the original Dolphin counterparts and in relation to the NACA geometric counterparts. Comparison Tables, diagrams of aerodynamic coefficients and lift – to - drag ratios are given, with all improvements shown in percentages.
After a successful numerical verification, better aerodynamic properties of the new family of hybrid Dolphin airfoils were confirmed experimentally on the example of the airfoil NA - DEL 2415. In the University wind tunnel ″Miroslav Nenadović″ of the Faculty of Mechanical Engineering of the University of Belgrade under the same flow conditions, NACA 2415, the original Dolphin airfoil 2415, and the new NA - DEL 2415 were tested. The results clearly proved that the NA - DEL 2415 hybrid airfoil has better aerodynamic characteristics compared to the other two tested airfoils. This confirmed the hypothesis and opened the way for the newly acquired family of hybrid Dolphin airfoils to be used both on general aviation aircraft and unmanned aerial vehicles.

AB  - Iosif Taposu has formulated a mathematical model and generated a family of air-foils whose geometry resembles the dolphin shape. These airfoils are characterized by a sharp leading edge and experiments have proven that they can achieve better aerodynamic characteristics at very high angles of attack than certain classical airfoils, with the nose geometry inclined downwards. On the other hand, they have not been applied to any commercial general aviation aircraft. The authors of this paper have been motivated to compare the aerodynamic characteristics of widely used NACA 2415 airfoil with Taposu???s Dolphin that would have the same princi-pal geometric characteristics. A CFD calculation model has been established and applied on NACA 2415. The results were compared with NACA experiments and very good agreements have been achieved in the major domains of lift and polar curves. The same CFD model has been applied on the counterpart Dolphin 2415. Results have shown that the Dolphin has a slightly higher lift/drag ratio in the lift coefficient domain 0.1-0.35 than NACA. On the other hand, at higher and lower lift coefficients, its aerodynamic characteristics were drastically below those of the NACA section, due to the unfavorable influence of the Dolphin???s sharp nose. A series of the Dolphin???s leading edge modifications has been investigated, gradually improving its aerodynamics. Finally, version M4, consisting of about 70% of Dol-phin???s original rear domain and 30% of the new nose shape, managed to exceed the NACA???s characteristics, thus paving the way to investigate the Dolphin hybrids that could be suitable for the general aviation industry.

AB  - Ovo istraživanje ima za cilj da doprinese slanju prve ljudske posade na Mars. U radu je simulirana anvelopa leta na Marsa u centrifugi visokih performansi. Visoka G-opterećenja prilikom poletanja, iskustvo nulte i mikrogravitacije, može rezultirati mnogim psiho-fiziološkim poremećajima kod astronauta. Ovo uslovljava potrebu za posebnim protokolima obuke. Predložena je anvelopa leta za prvu ljudsku misiju na Mars i simulirana u funkciji G-opterećenja. U radu su predloženi profili obuke. Poseban akcenat je stavljen na fazu lansiranja sa zemlje, kao i na fazu ponovnog ulaska i sletanja. Ponovni ulazak može biti posebno opasan, uz mnogo veća ubrzanja. Precizna simulacija zahteva pravilno podešavanje rotacionih uglova centrifuge. Prilagođavanje uglova se vrši u cilju smanjenja bočnih i poprečnih G-opterećenja. Ova studija će, nadamo se, pomoći da se čovečanstvo približi snu “Ljudi na Marsu”.
AB  - This research is an effort to contribute to the human exploration of Mars by simulating phases of the Mars flight envelope in a high performance human centrifuge. The crushing sensation experienced at high-G levels during take-off, the experience of zero and microgravity, can result in many psycho-problems to astronauts, obviating the need for realistic training protocols. The flight envelope for the first manned mission to Mars is proposed, and simulated in terms of G- load. Some training profile suggestions are given. A special emphasis is placed on the Earth launch phase, and on the Earth re-entry and landing phase. Re-entry can be especially dangerous with much higher accelerations. Accurate simulation requires a proper adjustment of rotational angles of the centrifuge. Angle adjustments are made in order to minimize side-Gy and transverse-Gx load. This study will hopefully help to move faster towards the dream of “Humans on Mars”.

Visoka G-opterećenja prilikom poletanja, iskustvo nulte i mikrogravitacije, može rezultirati mnogim psiho-fiziološkim poremećajima kod astronauta. Ovo uslovljava potrebu za posebnim protokolima obuke. Predložena je anvelopa leta za prvu ljudsku misiju na Mars i simulirana u funkciji G-opterećenja. U radu su predloženi profili obuke. Poseban akcenat je stavljen na fazu lansiranja sa zemlje, kao i na fazu ponovnog ulaska i sletanja. Ponovni ulazak može biti posebno opasan, uz mnogo veća ubrzanja. Precizna simulacija zahteva pravilno podešavanje rotacionih uglova centrifuge. Prilagođavanje uglova se vrši u cilju smanjenja bočnih i poprečnih G-opterećenja. Ova studija će, nadamo se, pomoći da se čovečanstvo približi snu “Ljudi na Marsu”., This research is an effort to contribute to the human exploration of Mars by simulating phases of the Mars flight envelope in a high performance human centrifuge. The crushing sensation experienced at high-G levels during take-off, the experience of zero and microgravity, can result in many psycho-problems to astronauts, obviating the need for realistic training protocols. The flight envelope for the first manned mission to Mars is proposed, and simulated in terms of G- load. Some training profile suggestions are given. A special emphasis is placed on the Earth launch phase, and on the Earth re-entry and landing phase. Re-entry can be especially dangerous with much higher accelerations. Accurate simulation requires a proper adjustment of rotational angles of the centrifuge. Angle adjustments are made in order to minimize side-Gy and transverse-Gx load. This study will hopefully help to move faster towards the dream of “Humans on Mars”.",

AB  - This paper represents an effort to enhance and contribute to the human exploration of Mars, by simulating phases of the Earth-Mars-Earth flight envelope in a high performance human centrifuge. Humans are the most valuable part of the Mars mission. The crew will encounter the Space, interplanetary and planetary surface environment, and has to remain productive during the whole mission. The crushing sensation experienced at high-G levels during take-off, zero and microgravity, can cause many psycho-physiological problems to astronauts. The human body undergoes major changes in Space, especially when returning from weightlessness and readapting to gravity. The centrifuge discussed in this paper, is in essence a robotic manipulator with three degrees of freedom of motion. It is capable of achieving extreme G-loads in short time intervals. In order to achieve an extreme gradient, the main drive of the centrifuge has to work with an overload in a short time interval. This allows an authentic G-simulation. The centrifuge has an onset rate of 9G/s. It consists of three independent controllable axes (angles): the roll, pitch and the planetary axis. The flight envelope for the possible manned Mars mission is examined, and simulated in terms of G in this paper. In order to get better acquainted with the conditions astronauts will be exposed in flight, and to improve astronaut training for the Mars mission, some training profile suggestions are also given in this paper. A special emphasis is placed on the Earth launch phase, as well as on the Earth entry and landing phase. The experience of launch, ascent, re-entry is simulated in terms of G. Astronauts experience a load of about 3G during take-off. Reentry can be especially dangerous with much higher accelerations, beside the fact that astronauts wear anti-G suits. Simulating the Earth-Mars-Earth envelope accurately requires a proper adjustment of the three rotational angles, which is also given in this study.

abstract = "This paper represents an effort to enhance and contribute to the human exploration of Mars, by simulating phases of the Earth-Mars-Earth flight envelope in a high performance human centrifuge. Humans are the most valuable part of the Mars mission. The crew will encounter the Space, interplanetary and planetary surface environment, and has to remain productive during the whole mission. The crushing sensation experienced at high-G levels during take-off, zero and microgravity, can cause many psycho-physiological problems to astronauts. The human body undergoes major changes in Space, especially when returning from weightlessness and readapting to gravity. The centrifuge discussed in this paper, is in essence a robotic manipulator with three degrees of freedom of motion. It is capable of achieving extreme G-loads in short time intervals. In order to achieve an extreme gradient, the main drive of the centrifuge has to work with an overload in a short time interval. This allows an authentic G-simulation. The centrifuge has an onset rate of 9G/s. It consists of three independent controllable axes (angles): the roll, pitch and the planetary axis. The flight envelope for the possible manned Mars mission is examined, and simulated in terms of G in this paper. In order to get better acquainted with the conditions astronauts will be exposed in flight, and to improve astronaut training for the Mars mission, some training profile suggestions are also given in this paper. A special emphasis is placed on the Earth launch phase, as well as on the Earth entry and landing phase. The experience of launch, ascent, re-entry is simulated in terms of G. Astronauts experience a load of about 3G during take-off. Reentry can be especially dangerous with much higher accelerations, beside the fact that astronauts wear anti-G suits. Simulating the Earth-Mars-Earth envelope accurately requires a proper adjustment of the three rotational angles, which is also given in this study. The longitudinal G-load is most important for training, given that it has the highest value in real flight. Angle adjustments are made in order to minimize side-load and transverse load, although the centrifuge may provide all three loads. The Earth-Mars-Earth envelope consists of many critical phases. Envelope simulations in a centrifuge are valuable for astronauts. Flight simulation is an essential component of aircrew training, providing a safe and reliable training environment.

AB  - Razvoj humane centrifuge visokih performansi ima za cilj da izađe u susret zahtevima za stvaranje sigurnog i bezbednog okruženja za trening pilota borbenih aviona, radi ispitivanja njihove tolerancije na velika opterećenja. Svrha razvoja uređaja za obuku, je da se ustanovi kako nespecifični režimi leta deluju na individualnu fiziologiju pilota na obuci, kao i njegovu sposobnost optimalnog izvođenja borbene misije pod datim opterećenjem. Razvoj je baziran na rešavanju strukturalnih problema, kreiranju kinematskih, dinamičkih i kontrolnih algoritama za simulaciju. Humana centrifuga, izložena u ovom radu, je projektovana kao sistem sa tri stepena slobode kretanja. Zbog izuzetnih performansi, uređaj centrifuge nalazi značajnu primenu u testiranju izdržljivosti materijala i avionske opreme. Na Institutu Lola, biće razvijen model u odgovarajućoj razmeri. Cilj razvoja centrifuge visokih performansi je, pre svega, da se simuliraju specifična opterećenja supermanevara i time obezbedi optimalan trenažni režim pilota, izlažući pilota na obuci velikom priraštaju opterećenja u kratkom vremenskom intervalu.
AB  - In this paper some aspects of Human Centrifuge development are given. The main objective is to emphasize the importance of high G pilots training. Terms such as 'high agility' and 'supermaeuverability' are briefly explained. The development of a High Performance Centrifuge is intended to meet requirements for creating a safe and secure environment for fighter pilots training. The purpose is to determine how non-specific flight regimes affect the individual physiology, as well as the ability to perform combat missions under a given load. The development is based on structural problems, creation of kinematic, dynamic and control algorithms. The Human Centrifuge, presented in this paper is designed as a system of three Degrees of Freedom of Motion. Due to its exceptional performances, the device has an important application in material testing and sustainability of overall airborne equipment. The manipulator will be produced in an appropriate ratio, as a model. The main goal of this paper is to underline the importance of optimal training, by ensuring a high G onset rate. Also, some basic technical data and diagrams are given, in order to make the reader familiar to motion simulation basics.

The main objective is to emphasize the complexity of choosing a drive, since it is a high power drive. The methodology for the main drive selection of a Centrifuge for pilot training, which is a manipulator with three degrees of freedom of motion, is built upon the main demand to achieve an extreme gradient and load coefficient per unit of time. The methodology consists of determining the necessary torque and power of the main drive of the Centrifuge. To achieve the main requirement, the engine has to work with an overload in a given time interval at the beginning. For calculations and diagrams, the MATLAB program was used. In this paper, an example of a motor of the Swiss manufacturer ABB is given. Its features are explained in detail, according to the needed torque and power of the main drive. All numerical values in this paper, are a part of a preliminary calculation.

Glavni cilj je da se istakne značaj razvoja različitih trening scenarija, kako bi se postigla optimalna spremnost pilota borbenih aviona. Ovo istraživanje bazirano je na standardu NATO STANAG 3827 AMD-a, koji propisuje vrednosti G tolerancija, koju posada treba da podnese. Posada koja ne završi uspešno trening Rapid Onset Rate (ROR) 7G za 15 sekundi sa anti-G odelom i Anti-G Straining maneuver-om (AGSM), smatraće se da ima nizak prag tolerancije na G opterećenje, što je objašnjeno detaljno u ovom radu. Profili za obuku su grafički predstavljeni, kao i ugaona brzina kraka, ugao valjanja i ugao propinjanja-poniranja za svaku vrednost opterećenja. Glavni zahtev humane centrifuge predstavljene u ovom radu, je da se postigne gradijent ubrzanja od 9G/s. Profili koji su prikazani u ovom radu su deo istraživanja Lola Instituta u Beogradu. U radu su dati i primeri scenarija za obuku pilota koji se primenjuju u nekoliko zemalja. G opterećenja koja prouzrokuju gubitak svesti kod pilota (G-LOC) su deo scenarija i neizbežna su tokom treninga u centrifugi. Efektivna obuka AGSM i povećanje G-tolerancija pilota, doprinose bezbednosti leta i na taj način se smanjuje rizik od G-LOC i vazduhoplovnih nesreća. Cilj ovog rada je da ilustruje značaj i složenost upravljanja i podešavanja parametara rada, kako bi se postiglo željeno opterećenje. .
AB  - In this paper, profiles for training in a High Performance Human Centrifuge (HPHC) are presented. The main objective is to underline the significance of developing various training scenarios in order to achieve optimal preparedness of fighter pilots. This research is based on the NATO STANAG 3827 AMD, a standard that provides values of G tolerance that an aircrew must sustain. An aircrew who do not successfully complete a Rapid Onset Rate (ROR) 7G for 15 seconds centrifuge profile with anti-G suit and straining maneuver will be considered to have low G tolerance, which is explained in detail in this paper. Training profiles are presented graphically, as well as arm angular velocity, roll and pitch angle for each load. The main demand for the Human Centrifuge presented in this paper is to achieve an onset rate of 9G/s. The graphs in this paper are a part of the research conducted in the Lola Institute Belgrade. The examples of training scenarios of several countries are given briefly. G-Induced Loss of Consciousness (G-LOC) episodes are unavoidable during centrifuge training. Effective training of Anti-G Straining Maneuver (AGSM) and increasing pilots G-tolerance contribute to flight safety and thereby reduce the risk of G-LOC and aircraft accidents. The aim of this paper is to illustrate the complexity of parameter settings in order to achieve desired loads. .
