Problems solved by technology

However, both of these two technologies have shortcomings. If there is a technology that can have the comprehensive advantages of the two technologies, it will accelerate the development of my country's aircraft carrier
[0011] The current situation is that the power of pneumatic vane motors is generally small, and there is no high-power vane motor that can directly use steam

Embodiment 1

[0032] A high-power steam motor for ejection and take-off of a carrier-based aircraft includes a motor casing 1, and left and right end covers 15 and 21 are respectively fixedly installed on the left and right sides of the motor casing 1. Inside the motor casing 1 are A cylindrical accommodating cavity, a steam inlet 9 is fixedly installed on the motor housing 1, a steam exhaust port 2 is fixedly installed on the side, and the steam inlet 9 and the steam exhaust port 2 are both connected with the accommodating cavity. A transmission shaft 14 is arranged in the cavity, and the transmission shaft 14 is offset from the center of the accommodation cavity and is rotatably arranged in the accommodation cavity. The transmission shaft 14 is provided with a toothed spline. A support frame 3 is installed at the spline part. The support frame 3 is fixedly connected to the toothed rotor 6 through the pin shaft 5. The two adjacent teeth of the toothed rotor 6 form a through groove, and an o...

Embodiment 2

[0043] Further, the number of the blades 8 is an even number, and the two opposite blades are rigidly connected by the blade connecting rod 7. The toothed rotor and the transmission shaft 14 are provided with ventilation holes 26 corresponding to the ventilation grooves 25 and fixed fan blades. The blade through hole 27 is on the same line as the ventilation hole 26, the fan blade can slide up and down through the blade through hole, and the connecting rod is increased to increase the stability of the blade.

[0044] The power of the motor in the present invention is provided by steam and the power is large, so it is called a high-power steam motor. In order to reduce the manufacturing difficulty of the rotor, a split rotor structure is designed; in order to reduce the overall quality of the rotating parts, a low-density rotor is designed; in order to ensure reliable output of high-power torque, a split-type rotor is designed to be embedded into a high-strength rotor through a ...

Abstract

The invention provides a high-power steam motor for catapult-assisted takeoff of a carrier-based aircraft. The high-power steam motor comprises a motor shell body, wherein a left end cover and a rightend cover are fixedly mounted on left and right side faces of the motor shell body respectively; a containing cavity is formed in the motor shell body; a steam inlet is fixedly mounted at the upper part of the motor shell body and a steam exhausting opening is fixedly mounted on a side wall; the steam inlet and the steam exhausting opening are communicated with the containing cavity; the containing cavity is internally provided with a transmission shaft; the transmission shaft is deviated from the center of the containing cavity and is rotatably arranged in the containing cavity; the transmission shaft is provided with a blade capable of sliding flexibly; the transmission shaft is driven through the blade. The high-power steam motor provided by the invention has the advantages of safety and reliability in working, relatively high starting torque and relatively wide power rang and rotary speed range and the like, and the cost is lower than that of a steam turbine under the same power.

Description

technical field [0001] The invention belongs to the technical field of aircraft carrier equipment, relates to a power part of a catapult on an aircraft carrier, and in particular relates to a high-power steam motor used for catapult take-off of a carrier-based aircraft. Background technique [0002] The catapult is one of the key equipment of the aircraft carrier. At present, the more mature catapult technologies include steam catapult and electromagnetic catapult. According to authoritative comments, steam ejection technology is relatively mature, highly reliable, and has the advantages of decades of mature use experience; however, it also has the advantages of large size, heavy weight, low efficiency, high requirements for auxiliary systems on board, and relatively low operation and maintenance costs. High, low output power, can only eject a certain weight of carrier-based aircraft and other disadvantages. The electromagnetic catapult is small in size, light in weight, hi...
