Technical Field

[0001] The utility model belongs to the technical field of aircraft arresting, and in particular relates to a variable damping energy absorber. Background Art

[0002] With the development of aircraft, ground support equipment is also constantly improving. Among them, aircraft arresting equipment has made certain progress. The core component of aircraft arresting equipment is the water turbine energy absorber, which absorbs the kinetic energy of the aircraft after landing on the ground, allowing the aircraft to land safely.

[0003] So far, the structure of traditional energy absorbers can only arrest aircraft of corresponding weight, and their use is greatly limited. In particular, with the rapid development of the aviation industry, aircraft of various weights and types have taken off and landed at multiple airports, and aircraft of different models have taken off and landed at the same airport, resulting in the inability of traditional energy absorbers to meet actual needs. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide an energy absorber capable of adjusting damping to meet the needs of intercepting different types of aircraft.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a variable damping energy absorber, comprising an energy absorber and a water storage tank, wherein the energy absorber is of a water turbine type, having a closed shell and a stator and a rotor which are concentrically assembled in the shell, wherein the stator is fixedly connected to the shell, the rotor can rotate relative to the stator, and the shell is filled with a fluid medium;

[0006] A water inlet and a water outlet are provided at the bottom of the shell of the energy absorber, and the water inlet and the water outlet are connected to the water storage tank through two water pipes, and a water pump is provided on the two water pipes;

[0007] Furthermore, a solenoid valve is installed on the top of the water pump;

[0008] Furthermore, a water level sensor is provided on the shell of the energy absorber.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model is easy to use and has a simple structure, and the damping of the energy absorber can be changed by controlling the content of the fluid medium inside the energy absorber to adapt to intercepting different types of aircraft.

[0012] The technical solution adopted by the utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0013] like Figure 1 As shown, the utility model provides a variable damping energy absorber, including an energy absorber 5 and a water storage tank 1. The energy absorber 5 is a water turbine type, having a closed shell and a stator and a rotor located in the shell and assembled concentrically. The stator is fixedly connected to the shell, and the rotor can rotate relative to the stator. The shell is filled with a fluid medium, that is, when the rotor rotates under the action of an external force, it can drive the fluid medium to rotate, bringing a certain damping to the external force. Until the kinetic energy of the external force is converted into the heat energy of the liquid and released.

[0014] A water inlet and a water outlet are provided at the bottom of the energy absorber 5 shell, and the water inlet and the water outlet are connected to the water storage tank 1 through two water pipes 4. Both water pipes 4 are provided with a water pump 3, that is, the two water pumps 3 are used to control the fluid medium in the energy absorber 5 shell to flow into the water storage tank 1, or the fluid medium in the water storage tank 1 flows into the energy absorber 5 shell.

[0015] The utility model connects the energy absorber 5 with the water tank 1 through two water pipes 4 and two water pumps 3. One of the water pumps 3 is used to discharge the fluid medium in the water tank 1 into the shell of the energy absorber 5, and the other water pump 3 is used to discharge the fluid medium in the shell of the energy absorber 5 into the water tank 1. Even the fluid medium is converted in the shell of the energy absorber 5 and the water tank 1. When the shell of the energy absorber 5 is filled with fluid medium, the energy absorber 5 is in working condition and can bring resistance. When the fluid medium in the shell of the energy absorber 5 becomes less, the resistance brought by the energy absorber 5 becomes smaller. In this way, the variable damping function is realized for the energy absorber 5.

[0016] In addition, as a preferred technical solution, a solenoid valve 2 is installed on the top of the water pump 3, and the solenoid valve 2 realizes the opening and closing of the water pump 3 through an external control circuit.

[0017] Furthermore, a water level sensor 6 is provided on the shell of the energy absorber 5 , and the water level sensor 6 is used to sense the water level of the fluid medium in the shell of the energy absorber 5 , and realize linkage control of the solenoid valve 2 through signal transmission.

[0018] The above embodiments only express the preferred implementation modes of the present invention. It should be pointed out that, for those skilled in the art, all improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
