Is provided.

[0010] An apparatus capable of generating thermal energy in a jet engine and a chamber 1 by a power generating element 3 and transferring the generated electric energy to an electric motor 4 mounted on a turbine to propel the turbine.

A structure in which an air duct 9a is provided inside and an air duct 10b is provided outside the inner peripheral wall 2 of the chamber chamber 1 so that the temperature difference of the power generating element 3 can be more stably obtained.

The torque transmission efficiency can be improved by installing the electric motor 4 directly on the shaft of the turbine.

By installing a device 7 capable of holding thermal energy between the inner peripheral wall 2 and the outer peripheral wall 5 of the chamber 1 and the power generating element 3, the heat retaining effect can be maintained and the thermal difference can be stably obtained. .

As an effect of the present invention, the thermal energy cannot be effectively used in the conventional jet engine (because the volume and weight cannot be increased) depending on the use conditions. Use of the obtained thermal energy as part of the propulsion energy of the jet engine without changing the volume and weight of the engine, by stabilizing the gap, installing an air duct, and using a power generating element and an electric motor together with the jet engine can do. Therefore, the energy saving effect can be sold.
