The invention provides a turbo-shaft engine with a radiating device and an unmanned helicopter. The turbo-shaft engine with the radiating device comprises an engine body and a cooling pipe which is arranged in the hollow interlayer in a spirally surrounding layer; a hollow interlayer is arranged in the engine body; a damping cavity used for accommodating a solenoid valve is formed in the hollow interlayer; the cooling pipe is connected with a power mechanism used for circulating a cooling medium; the end part of an exhaust pipe of the engine body is rotatably connected with a turbine disc; andthe turbine disc drives the power mechanism through a chain. The engine body is fixedly assembled on the unmanned helicopter; and an air cooling device which is connected with the power mechanism through a pipeline is arranged on the unmanned helicopter. According to the turbo-shaft engine with the radiating device and the unmanned helicopter, by means of arranging the solenoid valve internally,the engine room space occupation is reduced, and meanwhile, damping protection is performed on the solenoid valve; and the temperature of the engine body is effectively decreased by means of the cooling pipe which coils spirally, an exhaust end of the engine body serves as a power source, and the cooling medium is subjected to air cooling in a flying process of the unmanned helicopter, which ensures stable operation of the engine.
