Document Type and Number:
WIPO Patent Application WO/2022/100531
Kind Code:
A1
Abstract:
An auxiliary propulsion device for an aerospace liquid propeller comprising a main propulsion device, a left auxiliary device (3), and a right auxiliary device (10). The main propulsion device comprises a housing (1). A thermal insulation layer (8) is welded to an internal wall of the housing (1). An upper sealing plate (6) is welded to a top portion of the housing (1). A combustion chamber (2) is welded to a internal wall of a bottom wall of the upper sealing plate (6). A fuel gas channel (9) is disposed in an interior of the combustion chamber. An ignition device (7) is welded to an internal wall of a top portion of the fuel gas channel (9). A thrust control device (4) is fitted at an end of the fuel gas channel (9) away from the ignition device (7) and a tapered jetting pipe (13) is fitted at the end of the thrust control device (4). The left auxiliary device (3) and the right auxiliary device (10) are provided at two sides of the main propulsion device, and have the same internal structure as that of the main propulsion device, such that when the device is started, the function of auxiliary propulsion can be achieved. In addition, a top cover is configured to have a streamlined shape to reduce wind resistance. Outer walls at a respective side of the left auxiliary device and the right auxiliary device are provided with a guide plate so as to further reduce air resistance.
