AIR-JET PNEUMOSTATIC ENGINE Russian patent published in 2005 - IPC

FIELD: air-jet engines.

SUBSTANCE: proposed air-jet pneumostatic engine has housing, air intake, axial-flow multistage compressor, combustion chambers arranged inside housing, afterburner and jet nozzle. Several pneumostatic are arranged inside housing between axial-flow multistage compressor and afterburner. Shaft of pneumostatic engines are connected in tandem by means of couplings and are mechanically coupled with shaft of axial-flow multistage compressor. Inner spaces of hermetic housing of pneumostatic engines are pneumatically connected with high-pressure compressed air system. All pneumostatic engines are of similar design, each containing sealed housing with intake, exhaust and limiting valves and closed by front and rear covers. Several disks of similar design are secured on shaft of pneumostatic engines. Two blind rectangular section channels are made in body of each disk opening to side from axis of rotation and arranged at different sides from axis of rotation and turned through 180° relative to each other. Longitudinal axes of blind channels are parallel to one line of disk diameter and perpendicular to other line of disk diameter. Plane of bottom of each blind channel is arranged at angle to line passing through center of rotation and separating two opposite blind channels closed by covers made in form of ring sector placed inside guides and loaded by springs. Working medium of pneumostatic engine is high pressure compressed air.

EFFECT: reduced consumption of fuel and increased efficiency.
