The invention relates to a variable sweepback wing with a fixed wing spar, and relates to the technical field of aerospace equipment. The variable sweepback wing solves the problems that the rigidityof an existing variable sweepback wing is reduced and the hinge bearing at the hinged position of the wing and a fuselage is too high due to the fact that a movable wing spar exists. According to thevariable sweepback wing, the sweepback angle of the wing is changed, meanwhile, the span length and the span area of the wing are changed, and the ubiquitous problem that the existing variable sweepback wing is single in deformation function is solved. The wing comprises a fixed inner wing, a movable outer wing, a connecting rod and a driving device, the fixed inner wing and the connecting rod jointly form a wing framework to play a bearing role, the movable outer wing is tightly attached to the inner wing, and the driving device is arranged on the wing spar of the fixed inner wing and drivesthe movable outer wing to move through the connecting rod to complete deformation of the wing. According to the deformable wing, the fixed wing spar is reserved, the good bearing capacity is achieved,the sweepback angle, the span length and the wing span area of the wing can be changed within a large range, the lift-drag ratio of the wing can be adjusted, and the wing profile efficiency is improved.
本发明涉及一种固定翼梁的可变后掠机翼,它涉及航空航天设备技术领域。本发明解决了现有变后掠机翼由于存在可活动翼梁而导致的机翼刚性下降及机翼与机身铰接处铰链承载过高的问题。本发明在改变机翼后掠角的同时改变了机翼的展长及翼展面积,解决了现有变后掠机翼普遍存在的变形功能单一的问题。本发明包括固定内翼,活动外翼,连杆及驱动装置,固定内翼与连杆共同构成机翼骨架起承载作用,活动外翼紧贴于内翼之上,驱动装置置于固定内翼的翼梁之上并通过连杆带动活动外翼运动以完成机翼的变形。本发明变形机翼保留了固定翼梁,具有较好的承载能力,能够在较大范围内改变机翼的后掠角、展长及翼展面积,能够调节机翼升阻比,提升翼型效率。
