Description

technical field

[0001] The invention belongs to the field of aerospace vehicle control, and in particular relates to a quick-response direct force generating device, which is suitable for the quick-response direct force control of the aircraft and the active control of the high-speed flow field inside and outside the aircraft. Background technique

[0002] With the rapid development of supersonic / hypersonic aircraft technology, direct force control technology is becoming an effective means to improve the response speed of high-speed aircraft, improve the guidance accuracy, and increase the available overload and maneuverability. Compared with the aerodynamic control method based on the air rudder, the direct force control based on the lateral jet flow has the advantages of small time delay, fast response speed, and high control efficiency in high-altitude environments.

[0003] At present, the reaction force control system based on side jet flow mainly generates side jet for...

Embodiment Construction

[0025] See attached Figure 1~2 , an implementation example of a fast-response direct force generating device of the present invention, which is composed of a power supply system 1 and a spark discharge plasma synthetic jet actuator 2 . Wherein the spark discharge plasma synthetic jet actuator 2 such as figure 2 As shown, a cylindrical exciter body 24 is included, the section diameter of the exciter body 24 is Φ16mm, and the height is 20mm. The exciter body 24 and its cover plate 26 are made of commercially available glass ceramics or boron nitride ceramics with good insulation performance and machinability to reduce the processing difficulty of the exciter. The diameter of the cover plate 26 is the same as that of the exciter body 24. The diameter of the tube is matched, and the thickness is 3mm. The jet outlet hole 25 opened on the cover plate 26 is circular, and its diameter is Φ2mm. The jet outlet hole 25 can also choose different side inclination angles or pitch angles...
