Starting structure for turboshaft engine

The invention relates to the technical field of turbine shaft engine corollary equipment, in particular to a starting structure for a turbine shaft engine, which comprises an air inlet pipe, an impeller, a rotor and a stator, the impeller is rotatably mounted in the air outlet; a first air flow channel and a second air flow channel are formed in the impeller; the rotor is mounted on the impeller and can drive the impeller to rotate or rotate along with the impeller; a stator is disposed within the rotor. Compared with a traditional mode of additionally installing the generator, a device for supplying lubricating oil to the connecting position of the engine and the generator does not need to be additionally arranged, the service life of the generator is guaranteed, and the connecting structure and the pipeline layout are simplified. When power generation is carried out, cold air flowing in from the outside is shunted through the first air flow channel or the second air flow channel on the impeller in the rotat
