FIELD: engines and pumps.
SUBSTANCE: ramjet engine operating on metal powder fuel comprises starting system fuel feed system including fuel tank with metal powder fuel and perforated piston, and combustion chamber. Engine housing accommodates gas generator to initiate metal powder fuel feed system. Combustion chamber consists of at least 30 mm-long prechamber with dispenser arranged at its inlet to feed fuel at preset rate, igniter and final combustion chamber. Prechamber and final combustion chamber have air feed channels. Prechamber airflow allows complete suspension gasification with surplus air factor α=0.15…0.3.
EFFECT: higher heat release per unit volume due to complete combustion.
