The invention relates to the field of mechanical engineering, namely to propulsion engineering.The pneumatic engine consists of a looped air duct, which contains a main tank (38) for compressed air, an air duct (39), a valve (40), a manometer (41), flanges (42) with pipe branches (44), screws (43), connected to the air duct (15) of the main shaft (12) with the hollow head (13), the primary disk (1) with an opening (8), an air duct (34), a tank (45), a compressor (46), a valve (47).On one side of the disc (1) is made an inner hole (2) for rolling bearings (3), and on the outside is made a pulley (4) for the V-belt transmission of rotation to the compressor (46). The hole (2) is closed by a flange (5) with seal ring (6), which is attached to the pulley (4) by means of screws (7). On the opposite side of the disc (1) is made an inner hole (8), to the surface of which are uniformly welded blades (9). Between the holes (2) and (8) is made a flange (10), in which is placed a seal ring (11). In the hole (8) of the disk (1) is installed the head (13) of the main shaft (12), in which is made a longitudinal hole. In the head (13) is made a lateral slot (16) with an upper cut round the diameter of its cavity. The head (13) is closed from the end with a welded flange (18). The disk (1) is mounted on bearings (3) located on the shaft (12), which is mounted in the bore of the moving support (20) and is fixed with a screw (21). To the disk (1) with seal ring (24) by pins (22) and screws (23) is fixed the flange (25) of the pulley (26), in which are made a groove and an inner hole (27), in which are installed, respectively, a seal ring ( 29) and bearings (28), located on the shaft (33) of the air duct (34). The shaft (33) is mounted in the hole (35) of a moving support (36) and is fixed with a screw (37). |
