The invention discloses a momentum body appearance of an upper atmospheric aircraft. The momentum body appearance comprises an aircraft head, a body, a sweepback airfoil and a wingtip V-shaped tail. The head of the aircraft is a wedge-shaped polyhedron and is in butt joint with a rear body. The body is a multi-stage trapezoidal boss which shrinks backwards, so that the resistance of the body is reduced; the sweepback airfoil is connected with the body to realize static pitching stability; and the two V tails are positioned at the positions of wingtips. According to the invention, the momentum exchange principle that the upper atmospheric layer gas interacts with the object plane is adopted, a polyhedral aerodynamic shape meeting the low-resistance aerodynamic characteristic is designed, the fusion design of the aerodynamic performance and the solar wing is realized, the aerodynamic resistance compensation requirement of the aircraft in the airspace can be effectively reduced, and the hang time of the aircraft is prolonged.
本发明公开了一种上层大气层飞行器动量体外形,包括飞行器头部、本体、后掠翼面和翼尖V型尾。所述飞行器外形头部为楔形多面体,与后面本体对接;本体为向后收缩的多级梯形凸台,降低本体阻力;后掠翼面与本体相连,实现俯仰静稳定;两个V尾位于翼尖位置。本发明采用上层大气层气体与物面相互作用的动量交换原理,设计了一种满足低阻气动特性的多面体气动外形,实现了气动性能与太阳翼的融合设计,可有效降低飞行器在该空域的气动阻力补偿要求,延长飞行器滞空时间。
