Abstract

Abstract: A typical effect of the fluid-thermal-structural coupling of near-space hypersonic vehicles is thermoelastic deformation, which changes the aerodynamic force and trim, and further changes the flight trajectory and control scheme. In this paper, the in-house FL-CAPTER coupling software is extended to the field of flight mechanics, and a new method of trajectory simulation considering fluid-thermal-structural coupling effect is developed. A preliminary study of the influence of the fluid-thermal-structural coupling effect on flight trajectory at different coupling time scales is then carried out based on the boost-compression-wedge shaped configuration with self-trim control under given deflections of control surfaces. The results show that after taking the coupling effect into account, the deformation of the configuration will increase the trimming angle, the lift, the drag, and the flight height, decrease the lift-to-drag ratio, the Mach number, and shorten the range. At the meantime, the choice of the time step size of aerodynamic/trajectory coupling has a great influence on the trajectory simulation; and non-physical oscillations will appear when the step size is too big, distorting the calculated results. The proposed modification method based on the deformation interpolation technology can effectively improve the accuracy of the trajectory simulation, and weaken the non-physical oscillations caused by the excessively large time step size. Related research can provide important reference to the understanding of the coupling mechanism of the multi-field coupling effect and flight trajectory as well as the ballistic design.
