FIELD: aircraft engineering.SUBSTANCE: drone comprises airframe with lateral air intakes with air ducts and engine assy. Engine consists of tank with liquid fuel and ramjet. The latter comprises combustion chamber connected with air ducts, flame holders fitted in combustion chamber. Combustion chamber has heat resistant coating and solid propellant charge. Ramjet comprises solid propellant charge igniter and starting jet nozzle articulated with mid-flight jet nozzle. Air duct opening at combustion chamber inlet are plugged. Flame holders are arranged in air ducts ahead of jettisonable plugs. Flame holders with fixtures are composed of hydraulic cylinders with above-piston chambers communicated with the system for liquid fuel feed from tank into combustion chamber.EFFECT: fast acceleration, higher final speed.2 cl, 2 dwg |
