Electro-jet engine: a jet engine without turbine - Part 2. Electric power generation

This part studies theoretically and experimentally the conversion of thermal energy directly into electrical energy. The experimental part was based on the recovery of a part of the heat lost to the cold source, i.e. to the atmosphere, through the walls of hot part of a turboshaft jet engine. For the experimental part I used a small turboshaft jet engine installed on an ultralight helicopter. The recovery was done with a Seebeck bridge currently produced. These Seebeck bridges are manufactured in mass production, have a low maximum operating temperature compared to the temperature inside the jet engine and have a very low efficiency compared to current systems used in space technology.
