Description

A kind of detachable thermal source for aircraft infrared assembly calibration target plate

Technical field

The application relates to aircrafi calibration equipment manufacturing field, particularly a kind of detachable thermal source for aircraft infrared assembly calibration target plate.

Background technology

In aircraft infrared assembly is calibrated, need first aircraft jack-up to be adjusted to theoretical level state, then detect in setpoint distance at aircraft infrared assembly and the target center position of calibration target plate is adjusted to aircraft theory state, target plate is generally arranged level, plumb datum line that infrared assembly aims at, the induction thermal source of a little higher than ambient temperature is set at target center (i.e. level, plumb datum line point of crossing) simultaneously so that aircraft infrared target system benchmark look for and calibrate.

Seldom arrange special induction thermal source traditionally on target plate, major part adopts interim thermal source, and these thermals source do not have specificity, and have that power specification differs, outward appearance unsightly, deposit difficulty large, use the shortcomings such as inconvenient.

Along with the increase gradually in domestic each main engine plants aircraft model, aircraft maintenance place, the boresight frock of aircraft infrared assembly also increases thereupon, is angularly difficult to adopt interim thermal source again from seaworthiness, professional production, maintenance.Therefore need to design a kind of special thermal source for aircraft infrared assembly calibration target plate, require that it can be arranged on target plate and stable thermal source is provided, and easy to use.

Summary of the invention

For reaching above object, the application takes following technical scheme to be achieved:

A kind of detachable thermal source for aircraft infrared assembly calibration target plate, connected successively by end cap, fever cabinet, tail-hood and combine, thermal source switch is embedded on the surface of described end cap, and thermal source positive pole is encapsulated in end cap cavity, and light-emitting diode is embedded in described end cap sidewall; Thermal source negative pole is encapsulated in tail-hood cavity; Fever cabinet is arranged between end cap and tail-hood, comprises main cabin body, heating board, magnet, battery; Through in the middle part of the body of main cabin, install battery, battery plus-negative plate is connected with positive pole with the negative pole of end cap with tail-hood respectively; Two blocks of magnet are embedded in external surface two ends place, main cabin respectively, heating board is fixed on the external surface of main cabin between two blocks of magnet, and main cabin body opens radiating groove processed between heating board hot zone, and groove of sunkening cord is offered in side, pass through for heating board circuit, heating board is connected with power supply.

During use, magnet face be adsorbed in target plate aiming point, Push switch can realize the opening and closing of thermal source, and light-emitting diode is luminous indicating operating status when heating.

The advantage of this thermal source is directly to be adsorbed on the target plate that iron and steel makes, thermal source stable when internal battery can realize long, and this heat source configurations is small and exquisite, heating starting is fast, easy to use, to the various calibration target plates of aircraft infrared assembly, there is general applicability.

Below in conjunction with drawings and Examples, the application is described in further detail.
