MICROELECTROMECHANICAL ROCKET ENGINE Russian patent published in 2013 - IPC F02K99/00 B81B7/04 

FIELD: engines and pumps.

SUBSTANCE: microelectromechanical rocket engine is made in the form of a structure, from semiconductor silicon crystals, arranged one above another, in one of which there is a combustion chamber with a fuel element, and comprises a unit of fuel ignition with metal conductors. The combustion chamber with the fuel element is made in the form of nanocrystalline porous silicon with depth of not more than 60 mcm, pores of which are saturated by hydrogen and doped potassium nitrate. In the second plate there is a nozzle arranged symmetrically to the nanocrystalline porous silicon and coupled with it via metal conductors.

EFFECT: simplification and cheapening of a process of engine manufacturing, provision of high reliability of an engine according to parameters associated with engine operation: temperatures, mechanical loads, mode of engine operation and provision of normal gas dynamic function as a result of the proposed design and fuel.
