Description
Technical Field
The utility model belongs to the technical field of sighting instrument calibration equipment, specifically a laser target plate.
Background
A complete set of norton bombsight consists of two main components, a stabilizer and a sight. The stabilizer is actually a work platform kept horizontal by a gyroscope and is used for providing a stable work platform for the sighting device. Stabilizers are often used in conjunction with the autopilot of the bomber to directly control the aircraft to maintain level flight. Before use, the sight and the stabilizer must be carefully calibrated to ensure that the direction aimed by the sight coincides with the direction of flight of the aircraft. The sight part is the main working system of the whole Norton bombsight, and the system mainly comprises three parts: the system comprises a mechanical analog computer for calculating the impact point, a small telescopic eyepiece and a set of precise system consisting of a motor and a gyroscope, wherein the system can move the telescopic eyepiece to ensure that an aiming point on the ground is always positioned in the visual field. The early norton bombing sighting telescope is also provided with an automatic gyro horizontal stabilizer to ensure the horizontal position of the sighting telescope relative to a stable platform, but the mechanism is too complex and inconvenient to maintain, and then the sighting telescope is finally disassembled and replaced with a simple bubble type level gauge. The use of a norton bombsight is not very complicated. When the airplane approaches the target area, the bomber sighting telescope needs to use the telescopic eyepiece to find the target, and the process can be assisted by a set of reflectors. After the target is found, the bomber sight can place the target in the middle of the field of view, and then turn on the power switch of the norton bomber sight. Once the switch is turned on, the telescope eyepiece servo motor will ensure that the eyepiece is always aligned with the selected target. Since the angular velocity of rotation of the servomechanism to the telescopic eyepiece is dependent on the distance of the target and the approach velocity of the aircraft, this requires the bomber to set the airspeed and altitude of the aircraft at the norton bombsight based on the display data on the aircraft instruments.
At present, the conventional calibration method of the sighting device and the stabilizer is as follows: the absolute vertical and horizontal directions are marked by adopting the calibration ropes, the specific arrangement is that one calibration rope is connected with two preset calibration points at the bottom of the airplane body and then extends forwards and is fixed, the other calibration rope naturally droops and is positioned to intersect with the previous calibration rope and is fixed, the horizontal arrangement is marked at the intersection point by using one calibration rope and is fixed, at the moment, the cross axis coordinates at the marks of the three calibration ropes are positioned in front of the airplane and are aligned with the preset calibration points on the airplane body, then observing the set calibration target cord through the aircraft sighting device, adjusting the sighting center of the cross axle in the sighting device and the target cord to the corresponding alignment position, completing the calibration of the sighting device, because the aircraft body is very large, the parking position is not fixed every time, therefore, the calibration target rope is set in the complex mode every time, time and labor are wasted, and the precision is not high.
Therefore, aircraft maintenance workers have invented a laser cross-axis calibrator which can project a cross laser axis forward and has a self-leveling function, but the coordinate of the laser cross axis projected forward is very narrow, and the laser cross axis is difficult to be observed by a sighting device under some special environments, so that the laser cross-axis calibrator cannot be used.
