The invention aims to provide an unmanned aerial vehicle hydraulic catapult launching system which is compact in structure and short in response time. A buffer energy-absorption system is integrated in a hydraulic energy system. The technical scheme includes that in the hydraulic energy system, high-pressure hydraulic oil pumped out by a tandem pump group is divided into two paths, one path is connected with an energy accumulator through a hydraulic pipeline, the other path is connected with an oil tank through an electromagnetic overflow valve, the energy accumulator is connected with an oil inlet of a hydraulic motor through the hydraulic pipeline and an inserting valve with an electromagnetic directional valve, a sliding trolley slides in an accelerated manner under the action of power outputted by the hydraulic energy system, an electromagnet 2DT and an electromagnet 3DT are simultaneously powered off after the launching speed of an unmanned aerial vehicle is reached, the inserting valve is closed, the sliding trolley continues to move forwards under the inertia action of the sliding trolley, a traction belt drives the hydraulic motor to rotate reversely, the hydraulic oil is charged to the energy accumulator, kinetic energy of the sliding trolley is consumed, the sliding trolley decelerates to stop, and a buffer energy-absorption function is achieved.
