Abstract

An aircraft landing gear control handle comprises a casing, a control handle, a micro switch, the control handle is arranged in a guide groove of the casing, the lower end of the control handle is associated with the micro switch set in the casing, The upper end is provided with a light-emitting block, and the light-emitting block is connected with the control power supply inside the casing through the wire built in the handle rod. When the plane is flying in the daytime, the handle light block does not light up. When the aircraft is flying at night, the light-emitting block of the handle is powered on, and the light-emitting brightness is compatible with night vision. At this time, the driver can accurately judge the position of the handle in the dark cabin environment, so as to operate the handle accurately and effectively.

Description

An aircraft landing gear control handle

technical field

The present application belongs to the field of aircraft landing gear control design, in particular to the design of a landing gear control handle with night vision function.

Background technique

Most of the aircraft's landing gear retraction and retraction operating handles are equipped with light guide plates with adjustable brightness to adapt to day and night flight, but the light guide plates are only used for lettering on the display panel, and the brightness is limited. The handle head of the joystick is generally a purely mechanical part. When flying at night, the cockpit is in a dark cabin environment. At this time, the crew on board cannot quickly and accurately determine the state of the operating handle head of the landing gear, and the landing gear cannot be retracted and retracted in a timely and effective manner. operate. Since the landing gear retraction operation is an important operation after takeoff and before landing, this stage is an important stage in the flight. Therefore, improving the operability of the handle during night flight is of great help to improve the safety of the aircraft.

SUMMARY OF THE INVENTION

The purpose of this application is to design an aircraft landing gear control handle. By adding a light-emitting block at the handle head, when the aircraft flies at night, the handle light-emitting block is powered on, and the light-emitting brightness is compatible with night vision. At this time, the operator can be in the dark In the cabin environment, the position state of the handle can be accurately judged, and the handle can be operated accurately and effectively.

An aircraft landing gear control handle, comprising a casing, a control handle, a micro switch, the control handle is arranged in a guide groove of the casing, and the lower end of the control handle is associated with the micro switch arranged in the casing, and is characterized in that: A light-emitting block is arranged on the upper end of the operating handle, and the light-emitting block is connected with the control power supply inside the casing through the wire built in the handle rod.

When the plane is flying in the daytime, the handle light block does not light up. When the aircraft is flying at night, the light-emitting block of the handle is powered on, and the light-emitting brightness is compatible with night vision. At this time, the driver can accurately judge the position of the handle in the dark cabin environment, so as to operate the handle accurately and effectively.

The beneficial effects of the present application are: by designing a landing gear control handle with a night vision function, the present application takes into account the ergonomic problem during day and night flight, and has the function of preventing mis-receiving in the ground state, thereby reducing the risk of misoperation , which improves the safety of the aircraft. The invention has a simple structure, and can be widely used in the design of aircraft landing gear control handles in the military and civilian fields.

The application will be described in further detail below in conjunction with the accompanying drawings:

Description of drawings

FIG. 1 is a structural schematic diagram of an aircraft landing gear control handle according to the present application.

Number description in the figure: 1 shell, 2 joystick, 3 sleeve, 4 light block, 5 micro switch, 6 locking mechanism.

Detailed ways

Referring to the accompanying drawings, the aircraft landing gear control handle of the present application includes a casing 1, a control handle 2, a micro switch 5, and the control handle 2 is arranged in the guide groove of the casing 1, and the lower end of the control handle 2 is connected to the casing The micro switch 5 in the body is associated, and it is characterized in that a light-emitting block 4 is arranged on the upper end of the operating handle 2, and the light-emitting block 4 is connected to the control power supply inside the casing through the wire built in the handle rod.

In practice, the light-emitting block is preferably a ring-shaped LED lamp. There are two light-emitting blocks, the light-emitting blocks are fixed on both sides of the joystick head through spherical sleeves 3 arranged at the end of the joystick, and the sleeves 3 are fixed on the joystick by screws.

When the aircraft is flying in the daytime, the light-emitting block 4 does not emit light. When the aircraft is flying at night, the light-emitting block 4 is powered on, and the light-emitting brightness is compatible with night vision. At this time, the driver can accurately judge the position of the handle in the dark cabin environment, so as to operate the handle accurately and effectively.

The aircraft landing gear control handle in the embodiment is also controlled by a locking mechanism, when the aircraft is in the air state, the locking mechanism 6 does not work, and the operator can pull the handle from the "down" position to the "retracted" position at this time; When the aircraft is on the ground, the locking mechanism 6 locks the handle, and the handle cannot be turned from the "down" position to the "retracted" position, which prevents the aircraft from accidentally retracting the landing gear in the ground state.

Claims (3)

1. The aircraft landing gear operating handle comprises a shell, an operating handle, a microswitch and a control handle, wherein the operating handle is arranged in a guide groove of the shell, the lower end of the operating handle is associated with the microswitch arranged in the shell, and the aircraft landing gear operating handle is characterized in that a light-emitting block is arranged at the upper end of the operating handle and is connected with a control power supply inside the shell through a lead arranged in a handle rod.

2. An aircraft landing gear lever according to claim 1, wherein the light emitting block is an annular LED light.
