The invention belongs to the technical field of aviation aircraft design, and discloses a laminar flow control technology verification machine which comprises a fuselage, wings, verification wings, an empennage and a power device, the fuselage, the wings, the empennage and the power device form a conventional fixed-wing aircraft, and the verification wings are located on the symmetrical central axis of the fuselage and installed at the rear position above the fuselage in a back supporting mode. The plane shape of the verification wing is rectangular, the aspect ratio is 1-1.2, and the configuration wing section is a laminar flow wing section. The verification machine can be used for high-altitude high-speed flight verification of the laminar flow control technology, constraint during verification design of the laminar flow control technology is reduced, flight verification of the active laminar flow control technology is achieved, and the cost and risk of flight verification are reduced; the aircraft body is simple in structure, the verification wings are easier to disassemble and assemble, and when laminar flow control technologies with different attack angles are tested, the test can be completed only by enabling the verification machine to sideslip at a small angle.
本发明属于航空飞行器设计技术领域,公开了一种用层流流动控制技术验证机,包括机身、机翼、验证翼、尾翼和动力装置;其中,机身、机翼、尾翼和动力装置组成常规固定翼飞机,验证翼位于机身对称中轴线上,以背撑形式安装在机身上方靠后位置。验证翼的平面形状为矩形,展弦比1至1.2,配置翼型为层流翼型。本申请是一款可用于层流流动控制技术高空高速飞行验证的验证机,减小层流控制技术验证设计时的约束,实现主动层流控制技术的飞行验证,降低飞行验证的成本和风险;本申请机体结构简单,验证翼的拆装更加容易,在测试不同迎角的层流流动控制技术时只用让验证机小角度侧滑就可以完成测试。
