Problems solved by technology

At the same time, due to the limited means of controlling the attitude of the existing waverider aircraft, the robustness of the control system is poor, and there are defects in the control ability
In addition, due to the small pitch damping of existing waveriders, their pitch channels are prone to instability

Abstract

The invention discloses a wave rider aircraft with redundant pneumatic distribution. The wave rider aircraft adopts an ideal wave riding configuration as a precursor, two sides of the tail of the wave rider aircraft are provided with rotatable full moving control rudders, the upper and lower surfaces of the tail of the wave rider aircraft are provided with rotatable embedded type control surfaces, and two sides of the bottom surface of the wave rider aircraft are respectively provided with two groups of beveled spray pipes. The wave rider aircraft with the redundant pneumatic distribution, provided by the invention, has the advantages of excellent aerodynamic force property, good controllability, high robustness, and the damping adjustment is realized.

Description

technical field [0001] The invention belongs to the technical field of overall structural design of waveriders, in particular to a waverider with redundant aerodynamic layout and a control method thereof. Background technique [0002] Aerodynamic layout design is the basis of glider aircraft design. Under hypersonic conditions, the waverider configuration has better aerodynamic performance, and has become an effective attempt to break through the "lift-to-drag ratio barrier" faced by hypersonic flight of traditional aircraft. However, the ideal waverider configuration does not have any control mechanism for attitude adjustment. In the process of designing the aerodynamic layout of the gliding aircraft, it is necessary to modify the ideal waverider configuration. [0003] After our analysis, we found that the aerodynamic layout of the existing waverider aircraft is only based on the ideal waverider configuration, and the edges are properly blunted and modified, and the attit...
