AbstractWe describe a thermionic method and device for cooling turbine blades of spacecraft gas turbine converters, based on a new physical principle called thermionic emission, i.e. electrons being emitted by heated metal. This device will allow the reliability and durability of turbine blades of gas turbine converters to be enhanced, and their efficiency factor to be significantly increased, leading to the possibility of creating different mass-class spacecraft with higher power consumption and with longtime lifecycle. The thermoionic way and device of cooling of the shovels of turbines of the gas-turbine converters of spacecrafts based on the new physical principle — the phenomenon of a thermionic emission, emission of electrons are described by heated metal. These way and the device will allow to increase reliability and durability of shovels of turbines of gas-turbine converters of spacecrafts of any dimension, and also to considerably increase their efficiency, having provided a possibility of creation of spacecrafts of the increased power consumption with the long term of the fissile existence. Realization of a thermoissue way and the device of cooling of shovels of turbines allows to increase temperature of a working body in front of the turbine till 2600 … 2700 K for organic fuels above for other working bodies and sources of thermal energy (it is reached at the size of a work function of electrons about 1.6 … 1,7 eV), to increase efficiency of gas turbine converters of spacecraft to 43-44%, to reduce by two-three times temperature stresses in turbine blades, to reduce the cost of manufacture and operation of turbine blades of gas turbine converters of spacecraft, and also to carry out diagnostics of a thermal condition of the turbine and other high-temperature elements continuously in real time.
