The invention discloses an aircraft variable nose cone device based on a parallel mechanism, and belongs to the technical field of aerospace, and the aircraft variable nose cone device comprises a nose cone shell, a telescopic bending driving rod piece mechanism, an auxiliary movement rod piece mechanism and a driving mechanism. A parallel mechanism and a mechanism moving target are combined, the actual application freedom degree requirement serves as the starting point, by means of configuration integration of the parallel mechanism, a constraint spiral method is used for conducting shape integration design on all parallel branch chains, an appropriate mechanism configuration is selected, and only two drives need to be installed on a nose cone base section; the overall telescopic and bending movement of the nose cone can be realized by controlling the rotary movement of a driving rod of the telescopic and bending driving rod mechanism, the telescopic and bending can generate lift force and yawing moment, so that the maneuverability of the aircraft is changed, and by virtue of the special streamline structure, the aerodynamic resistance generated in the flying process of the aircraft body can be reduced, and the maneuverability of the aircraft is improved. And the structure in the cavity can be protected from being impacted and vibrated, so that the flight path change can be realized, and the flight performance is improved.
本发明公开了一种基于并联机构的飞行器变头锥装置,属于航空航天技术领域,包括头锥外壳、伸缩弯曲驱动杆件机构、辅助运动杆件机构、驱动机构。本发明将并联机构与机构运动目标相结合,以实际运用自由度需求为出发点,借助并联机构的构型综合,利用约束螺旋法对各并联支链进行型综合设计选取合适的机构构型,并且只需要在头锥基段安装两处驱动,控制伸缩弯曲驱动杆件机构驱动杆的旋转运动即可实现头锥整体的伸缩和弯曲运动,伸缩和弯曲能够产生升力和偏航力矩,从而改变飞行器的机动性,且凭借着其特殊的流线型结构,既可以减轻机体在飞行过程中产生的气动阻力,而且也可以保护腔内结构免受冲击和振动,从而可实现飞行轨迹变化,提升飞行性能。
