The invention discloses a telescopic four-shaft rotor hydraulic aircraft with high torque density. The telescopic four-shaft rotor hydraulic aircraft comprises a rotor control mechanism, a supporting mechanism and an aircraft body, the rotor wing control mechanism is fixed on the supporting mechanism, a rotor wing speed control module controls a speed control motor pump to suck oil from an oil tank, the rotating speed of a rotor wing hydraulic motor is adjusted by controlling the hydraulic oil flow of a speed control oil way through a servo valve, and then the rotating speed of a connected rotor wing is changed; the rotor telescopic module is used for controlling the extending distance of a linear cylinder piston rod through an oil way based on an adjusting motor pump and adjusting the distance between rotors and the center; the supporting mechanism is movably connected with the aircraft fuselage through the hydraulic drive spherical joint, and when the fuselage inclines by an angle, the hydraulic drive spherical joint adjusts the full-cycle hydraulic motor to control the included angle between the fuselage and the supporting mechanism through inclination angle signal feedback of a gradienter installed on the fuselage so as to ensure that the fuselage is horizontal.

    本发明公开了一种高扭矩密度的可伸缩四轴旋翼液压飞行器,包括旋翼控制机构、支撑机构和飞行器机身;旋翼控制机构固定于支撑机构之上,其中旋翼控速模块控速电机泵从油箱吸油,通过伺服阀控制控速油路液压油流量来调整旋翼液压马达的转速,进而改变连接的旋翼旋转速度;旋翼伸缩模块用于基于调节电机泵通过油路来控制直线缸活塞杆伸出距离,调整旋翼距离中心距离;支撑机构通过液压驱动球形关节与飞行器机身活动连接,当机身发生角度倾斜时,液压驱动球形关节通过机身安装的水平仪倾斜角度信号反馈,调节全周液压马达控制机身与支撑机构间夹角,以保证机身位置水平。
