The invention provides a divergence and air film double-cooling system applied to the surface of a nose cone of a reciprocating hypersonic aircraft. The system mainly comprises a hypersonic aircraft nose cone surface, a divergent cooling system and an air film cooling system, the surface of the nose cone of the hypersonic aircraft is divided into two areas which are a stationary point area containing stationary points and a non-stationary point area not containing stationary points, the nose cone surface stationary point area adopts divergent cooling, a cooling agent is liquid water, the nosecone surface non-stationary point area adopts gas film cooling, the cooling agent is nitrogen, and the divergent cooling system and the gas film cooling system work independently. The cooling requirements of the stationary point area and the non-stationary point area can be met at the same time, the cooling efficiency of the stationary point area is not lower than 90%, the cooling efficiency of the non-stationary point area is not lower than 60%, and the weight of the cooling agent needing to be carried by the aircraft can be effectively reduced.
