天津市读者李伟来信问:现代飞机的气动加热对飞机有什么影响,如何解决? 答:一般飞行器,如飞机、导弹等在大气中飞行时,由于飞行速度越来越快,常常要考虑由此引起的飞行器表面温度升高现象,这就是所谓的“气动加热”同题。气动加热的实质在于,飞机在大气中飞行时,由于迎面气流与机身头部相遇时受到压缩,使得局部气流受到阻滞,从而使气流速度降低;同时,由于空气具有粘性,在机
Tianjin Readers Li Wei letter asked: modern aircraft aerodynamic heating of the aircraft have any effect, how to solve? A: The general aircraft, such as aircraft, missiles and other air in the flight, due to the faster and faster flights, often have to consider the This caused the aircraft surface temperature phenomenon, which is the so-called “pneumatic heating” with the title. The essence of pneumatic heating is that when the aircraft is flying in the atmosphere, the local airflow is blocked due to the compression of the oncoming airflow and the fuselage head, so that the airflow speed is reduced. At the same time, due to the air being viscous,
