飞机大迎角横侧气动特性是决定其机动性及敏捷性的主要因素之一。本文就采用机头边条改善飞机大迎角横侧气动特性进行了讨论。着重对机头边条的大小、安装位置等对飞机稳定性的影响进行讨论。试验是在气动中心低速所４ｍ×３ｍ和３．２ｍ风洞中进行的。
Lateral aerodynamic characteristics of the aircraft at high angles of attack are one of the major determinants of maneuverability and agility. In this paper, the use of head trim to improve the aircraft at high angles of attack on the lateral aerodynamic characteristics were discussed. Focus on the size of the head edge, the installation location on the stability of the aircraft are discussed. The tests were carried out in 4m × 3m and 3.2m wind tunnels at low speed in the aerodynamic center.
