The invention discloses a braking rotor type propeller fixed wing helicopter. Two rotor wings are arranged on the wing-shaped small towers at the head and the tail of a fuselage; blades of the rotor wing are connected with a rotor wing shaft through a propeller shell; and the propeller shell is composed of variable pitch hinges. A total pitch controller and a periodic variable pitch controller arearranged to control the pitch change of the rotor blades; upper single wings are arranged in the middle of the fuselage; the left side and the right side of the upper single-wing straight section areeach provided with a variable-pitch propeller. An engine is arranged to drive a differential mechanism through a gearbox and a clutch. The first output shaft of the differential mechanism drives thetwo rotors through an overrunning clutch, a universal shaft and a rotor synchronous reverser; the second output shaft of the differential mechanism drives left and right variable pitch propellers through an overrunning clutch, a universal shaft and a propeller synchronous reverser. A wheel type undercarriage is arranged, different output shafts of the differential mechanism are braked through thebrakes, the power of the engine is distributed to the rotor wings or the variable-pitch propellers, the rotor wings are braked and stopped into small fixed wings in a fixed wing mode, the stall problem of backward blades is solved, and the aircraft is suitable for taking-off, landing and rapid level flight of an airport.

    一种制动旋翼式螺旋桨固定翼直升飞机,两个旋翼设置在机身头尾的翼型小塔上,旋翼的桨叶经桨殼与旋翼轴连接,桨殼由变距铰组成,设置总距和周期变距控制器操纵旋翼桨叶的桨距变化,机身中部设置上单翼,上单翼平直段的左右两边各设置一个变距螺旋桨,设置发动机通过变速箱和离合器驱动一个差速器,差速器第一输出轴通过超越离合器、万向轴、旋翼同步反转器驱动两旋翼,差速器第二输出轴通过超越离合器、万向轴、螺旋桨同步反转器驱动左右变距螺旋桨,设置轮式起落架,通过制动器制动差速器的不同输出轴,将发动机功率分配给旋翼或变距螺旋桨,在固定翼模式,将旋翼制动停止成小固定翼,消除了后行桨叶失速问题,适合要求无机场的起降和快速平飞。
