摘要: 飞翼布局作战飞机采取新型操纵面,且取消了常规的用于起降增升的襟翼装置,研究了该特殊构型飞机起降飞行的操纵新机理.以一种飞翼布局飞机为例,根据风洞试验的结果比较了典型的飞翼与常规布局作战飞机低速气动特性的差异;进而计算了其起降性能,并与典型常规布局作战飞机F-16进行了对比分析.结果表明,由于全翼面的布局设计,飞翼飞机具有翼载荷低的特点,使其更容易满足起降性能的要求.研究结果对飞翼布局作战飞机的设计和性能评估具有重要的参考价值.Abstract: Innovative control surfaces are implemented on the flying-wing configuration combat aircraft, and the flaps of traditional aircraft which are used for lift increasing during take-off and landing are canceled. The control principles during take-off and landing were summarized. A flying-wing configuration aircraft was chosen for instant, so the low-speed aerodynamic characteristics of the typical flying-wing configuration aircraft were compared with conventional aircraft based on results of tunnel tests. Then the performances of take-off and landing were calculated and compared with typical traditional fighter F-16. The results prove that, the inherent feature of all-wing design brings low wing-load, which makes take-off and landing performances of flying-wing configuration fighter easy to satisfy. The valuable references were provided for estimating the battle effectiveness and designing of flying-wing configuration fighter.
