According to the active jet flow enhanced empennage device and the control method, energy of airflow on the lower surface of an empennage is increased through jet flow, the angle of the empennage can be further increased compared with a traditional active empennage, the stall phenomenon does not occur, and therefore larger downward pressure is generated; different from common methods in the aviation field, a plurality of discrete independent nozzles are adopted for spraying air, a plurality of independent pressure regulating valves are in one-to-one correspondence with the nozzles, and the air spraying pressure of each nozzle can be independently and accurately regulated; different from schemes of a part of vehicle enterprises, high-pressure gas can be actively generated, jet flow can be formed, decoupling with vehicle running is achieved, and the jet pressure can be freely and continuously adjusted within a certain range; compared with an existing scheme, the airflow control capability is higher.
本发明提出一种主动式射流增强尾翼装置及控制方法,通过射流增加尾翼下表面气流的能量,使尾翼角度相比传统的主动尾翼可以进一步增大而不发生失速现象,从而产生更大的下压力;与航空领域常用做法不同,本发明采用多个离散的独立喷口喷气,多个独立的调压阀与喷口一一对应,可以单独精准调节每一个喷口的喷气压力;与一部分车企的方案不同,本发明可主动产生高压气体并形成射流,与车辆的行驶解耦,使喷气压力在一定范围内可自由连续调节;本发明相比现有方案对气流的控制能力更强。
