... of a star's resources to generate exergy. A classification of stellar engines is proposed. A class A stellar engine uses the impulse of the radiation emitted by a star to produce ... this paper as a combination of both class A and class B stellar engines. Class A and C stellar engines are associated with an increase in a star's photosphere temperature. It ... that there is a minimum radius for a class C stellar engine to provide useful power. An optimum class C stellar engine radius allowing maximum power delivery has been identified. When our ...

... -cycle (ATREX) has been designed and tested at sea level static conditions, which demonstrated the engine system and component performance. Experimental and numerical research of the components have also been conducted ... precooler tubes using methanol. As the next step, the development of a subscale flight-type engine (S-engine) has started. The partial expander cycle was selected instead of the full expander cycle ...
