COMPUTER-AIDED DESIGN AT THE STAGE OF THE TECHNICAL APPEARANCE ANALYSIS OF AEROSPACE PLANE

A. V. Brykalov

Abstract


The method of solving the problem of technical appearance of aerospace plane is considered. The generalized criteria of estimation, restrictions and assumptions are given. The mathematical model of movement of an aerospace plane on rebound trajectory is described. The results of calculation of aerodynamic and trajectory characteristics of aerospace airplane with the use of proposed programs computer simulation are presented. The calculation of aerodynamic characteristics is performed using the computer simulation system ANSYS FLUENT. For the computer aerodynamic modelling the electronic three dimensional (3D) model of the speaker in the SolidWorks program, corresponding to the size and configuration of the general view drawing is developed. In the Workbench environment the calculation grid of the modeling area is developed, which together with the calculation grid of the surface of the modeling object is 1304186 knots and 7325935 elements.
