Novel hypersonic missile outer-layer wind turbine blade heat preventing and cooling technology

Abstract

The invention provides a novel aircraft and missile wind turbine blade heat preventing and cooling technology, and particularly relates to a novel hypersonic missile outer-layer wind turbine blade heat preventing and cooling technology. Wind turbine blades are arranged on the outer layer of a hypersonic missile, high-speed airflow is converted into acting kinetic energy, the high-speed airflow blows the blades to move, the blades drive wind turbines to rotate, the blades rotate at high speed to blow cold air to the outer layer of the missile, the cold air blows to the outer layer of the missile for cooling, meanwhile, hot air emitted by the missile is blown out to be exhausted to the rear portion of the missile, no shock wave or viscous friction is generated by the outer layer of the missile any more, and no pneumatic heating or thermal barrier is generated any more. No infrared radiation is generated, no directional echoes are generated, and an American antimissile system and a radar cannot carry out infrared tracking imaging. The pneumatic heating problem of the hypersonic missile of six times to 23 times is solved through the technology, and the technology can be suitable for various hypersonic aircrafts.

Description

technical field [0001] The technology relates to a new heat-preventing and cooling technology that the wind wheel blades installed on the outer layer of a hypersonic missile convert high-speed airflow into kinetic energy for work, blowing cold air to reduce the temperature of the missile, and fanning out the hot air of the missile. Background technique [0002] The difficulty encountered in the development of hypersonic vehicles is the problem of aerodynamic heating, the so-called thermal barrier . The more important means to overcome the thermal barrier is to provide thermal protection for the aircraft. The thermal protection methods are divided according to the heat protection mechanism: heat sink heat protection; radiation heat protection; sweating cooling heat protection and ablation heat protection. [0003] Heat sink heat protection mainly uses the heat capacity of the material to absorb heat. Any material has a heat capacity, but first of all, it must have a large s...
