Embodiment Construction

[0019] The method for positioning the radome outside the frame will be described below in conjunction with the accompanying drawings.

[0020] Firstly, using the principle of aircraft level measurement, use a spirit level to adjust the aircraft fuselage to a horizontal state, and fit the rear part of the radome on the frame plate of the fuselage, and use the bracket to lift the radome at the approximate installation position.

[0021] Then measure the center B of a component on the fuselage with a level and a leveling rod or a long steel ruler, and record the value H of the leveling ruler or long steel ruler read in the level B ; Then use the same method to measure the sharp point A of the radome, and record the value H A ;Adjust the sharp point A of the radar dome so that

[0022] At the same time, pull a thin cotton thread above the radome, the front section of the thin cotton thread passes through two punctuation points on the central axis of the fuselage, and the other ...

Abstract

The invention relates to a radar-dome positioning method without a special tooling, and belongs to methods for positioning aircraft radar-domes outside frames. The back of a radar-dome sleeves a frameplate of a body and is fixed relative to the position of an aircraft, and coaxiality of the radar-dome relative to a theoretical axis is only related to deviation of the tip of the radar-dome relative to a theoretical position, so that a sharp point of the radar-dome can meet positioning requirements within a circle taking a theoretical center as a circle center and with the diameter of phi D. The positioning requirements of the radar-dome can be met outside the frames without the special tooling.

Description

technical field [0001] The invention relates to a radome positioning method without special tooling, and belongs to a method for positioning an aircraft radome outside the aircraft. Background technique [0002] According to the modification requirements, it is necessary to replace the structural cover of a certain type of aircraft that has been delivered for final assembly with a radome. When positioning the radome, it is necessary to ensure that the coaxiality between its axis and the theoretical axis in the aircraft coordinate system is φD. However, since the aircraft cannot be returned to the stand for positioning, and special tooling cannot be used to ensure its positioning accuracy, it is necessary to formulate a method suitable for radome positioning without special tooling on site. Contents of the invention [0003] In order to overcome the above-mentioned problem of radome positioning and installation, the present invention provides a radome positioning method wi...
