FIELD: motors and pumps.
SUBSTANCE: invention relates to rocket engineering and may be used for the development of aircrafts operating on two-mode engine. The two-mode engine operating on solid fuel includes front lid, housing and serial charges of the first and second modes, initiating units, intermediate bottom, sleeve and nozzle. The sleeve of the second mode charge is coaxially divided before initiating unit. The external part of the sleeve passes into heat-insulating cover closing the front part and front end of the charge and is leak-tightly attached to the housing collar. The central part of the sleeve is perforated and fixed to the front lid. The initiating unit is connected with the space between the second charge and sleeve through the nozzle installed in the external part of the sleeve by means of tight sliding seal. The above nozzle is fastened to leak-tight seal in the initiating unit.
EFFECT: improved reliability of jet engine.
