The invention relates to an aviation dynamic differential pressure all-wing aircraft. An airfoil profile of the aircraft comprises an upper airfoil surface and a lower airfoil surface. The section lines of the airfoils are all composed of curves of a monotonically decreasing function from the front edge to the rear edge. The structure is simple, and when the lower wing surface does work on windward airflow, the flow speed is reduced, the static pressure intensity is increased, and upward thrust is generated; the upper airfoil does not do work, airflow flows back, static pressure is reduced, upward pulling force is generated by the airfoils, and therefore the double-airfoil lift airfoil profile with the upper airfoil and the lower airfoil simultaneously and consistently upward lift force is formed, the sum of the lift force of the two surfaces is larger than that of an existing single-face lift airfoil profile, and the airfoil efficiency is further improved by optimizing the lift-drag ratio. By adopting the wing section line and the spanwise line rear corner, shock waves are weakened to be low-sound-velocity object plane static pressure, damage of the shock waves is avoided, and the strong resistance effect is reduced.
本发明涉及一种航空动压差全翼机,其翼型包括上翼面和下翼面组成。其翼面截线均由前缘至后缘单调下降函数的曲线组成。本发明结构简单,在下翼面对迎风气流做功下,流速减慢,静压强增高,产生向上的推力;上翼面不做功,气流倒流,静压强减小,翼面产生向上的拉力,从而构成上、下翼面同时升力一致向上的双翼面升力翼型,二面升力之和大于现有的单面升力翼型,再经优化升阻比,翼效率得到进一步提升。采用翼截线和展向线后转角,弱化激波为低声速物面静压强,避免激波的毁坏与降低强阻力作用。
