We describe a 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 spacecraft with higher power consumption and longer active functioning perio.
