AB  - In the times of significant development of high-speed train transportation and taking the primacy over the others, one of the major designing tasks is to predict accurately and fast the vehicle’s main performances, especially aerodynamics. Motivated by the bionic design of representative Japan’s train Shinkansen, the presented bionic design was based on the observations of the kingfisher from Serbian national heritage collection. The specimen beak shape has been measured, by laser scanning, and converted to a mesh. Afterward, the longitudinal cross-section of the beak was implemented to a bionic high-speed train design. As the critical, the conditions of the train’s forehead entering into the tunnel were selected, while the case scheme employed relative motion. The forehead contour distributions of the surface temperature, skin friction coefficient, and the pressure distributions, obtained with computational fluid dynamics, were used for the prediction of the transition zone extension. The anomalies in surface temperature behavior were additionally analyzed by pressure and density distribution inside the tunnel and over the forehead. Besides the gross time history of the pressure derivative of time is in correspondence with the referent, it was interpreted that the true biological form is not fully suitable for adoption for bionic design. The development of this design, employing contour simplification by the close parabolic function will continue in the future. This work suggests an economic and efficient approach to analyze the results of the Reynolds-Averaged Navier-Stokes equations adequate for the concept design stage.

AB  - The main goal of this paper is to expand previously conducted study and consequently to upgrade the proposed multimodular numerical framework developed for fluid-structure interaction simulation (FSI) and multidisciplinary design optimization (MDO) purposes, in a manner that thermal-structure interaction is observed and implemented into the established numerical framework. The upgraded and considerably improved algorithm was used for MDO of the short-range ballistic missile (SRBM) model. Because of its high-speed regimes, this aircraft model was selected for the purpose of numerical modeling and optimization of aerodynamically heated structure. The present study is concerned with a broader observation of critical multipoint flight conditions and represents a more realistic scenario, which indicates this study as one contribution more in a scope of fluid-thermal-structure interaction (FTSI) numerical modeling and optimization. With respect to predefined objectives and constraints, multidisciplinary shape optimization of the fin structure resulted in overall improvement of the missile initial performances. Also, aerothermally induced critical responses of the fin structure were prevented. Numerical modeling of FSI/FTSI and MDO within an industry-accepted design tool resulted in powerful monolithic environment, which, with adopted multipoint regimes and multicriteria settings, was used for aerodynamic-thermal/structural optimization. The obtained results were compared with the results from the previous study conducted without thermal effects.

Sila otpora po jedinici površine panela je određena kao funkcija brzine voza i položaja aerodinamičke kočnice.

AB  - This work presents the research results of the aerodynamic brake influence, mounted on the high-speed train's roof, on the flow field and overall braking force. The train consists of two locomotives at each end and four passenger cars between, with 121m of overall length. Aerodynamic brakes are designed to generate braking force by means of increasing the aerodynamic drag by opened panels over the train. Flow simulations were made by Fluent 12.1 software, for the train without and with one, two and three aerodynamic brakes, and velocities of 30, 50 and 70m/s. Drag force per unit panel area was determined as a function of train's velocity and the brake position. Contributions to train's gross braking force of each brake, obtained by simulations were: for first 24%, for second 15% and third 14.8%, and showed, also with panels' pressure distribution, good correlation with the aerodynamic drag calculations for flat plate orthogonally disposed to flow stream.

AB  - This paper presents the results of simulations, carried out with the Fluent software, for a high speed train moving at 70 m/s for 4 cases: the train configuration without aerodynamic brakes, the train configuration with one aerodynamic brake, with two, and with three aerodynamic brakes deployed over the roof of the train. We have determined the braking force per unit area of aerodynamic brakes and compared our results to the results found in literature. Since it is known that the brake panel installed in the first position creates the greatest resistance, while for the brakes in the second and subsequent positions the intensity of resistance decreases, we analyzed the effect of serial interference and determined the contribution of each brake individually to the total braking force, depending on its position.

AB  - This paper presents the aerodynamical brake system, as second brake system, in cases when it is necessary to speed down the train or at emergency situations when primary brake system Is out of order. In this brake system, braking force is a result of aerodynamical drag generated on pulled-up aerodinamical brake panels. These panels are especially effective at high speeds because aerodynamical drag of panels is proportional to second exponent of vehicle's speed. Calculation of braking force by panel surface unit was derived for the aerodynamical brake of concave shape and it was compared with test results for Maglev train on railway Yamanashy in Japan.
