The invention provides a thermal protection device of a reentry vehicle and a control method.The device comprises a gas cylinder, an adjusting valve, an angle changing module and a controller, and one end of the adjusting valve is connected with an outlet of the gas cylinder; the variable-angle module comprises a hose and a transmission mechanism, one end of the hose is connected with one end, away from the gas cylinder, of the regulating valve, one end of the transmission mechanism is connected with the hose, and the other end is connected with the regulating valve; and the controller is respectively connected with the regulating valve and the transmission mechanism. The output flow of the adjusting valve is adjusted through the transmission mechanism, more accurate jet flow can be carried out according to changes of complex flight working conditions, the aircraft has higher adaptability in the whole flight process, and meanwhile the jet flow can be saved; the jet flow angle of the hose is adjusted through the transmission mechanism, jet flow can directly face incoming flow under multiple attack angles, and the jet flow is efficiently utilized; and by integrating jet flow adjustment and jet angle adjustment, the load space is saved, and the product integration degree is improved.

    本发明提供了一种再入飞行器的热防护装置及控制方法,其中,该装置包括:气瓶、调节阀、变角度模块和控制器,调节阀的一端与气瓶出口连接;变角度模块,包括软管和传动机构,软管的一端与调节阀远离气瓶的一端连接,传动机构一端与软管连接,另一端与调节阀连接;控制器,分别与调节阀和传动机构连接。通过传动机构调节调节阀的输出流量,可以针对复杂飞行工况的变化进行更精准的射流,使其飞行器整体飞行过程中具有更强的适应性,同时可以节省射流流量;通过传动机构调节软管的射流角度,可以在多攻角下实现射流正对来流,对射流进行高效利用;通过将调节射流流量和射流角度集成,节省了载荷空间,提高了产品集成度。
