Embodiment Construction

[0019] Combine below Figure 1 ~ Figure 4 The present invention is further described in detail with specific embodiments: based on the fact that there are defects in the actual application of the special turntable in the airborne radome electrical performance testing system, in order to overcome the interference between the antenna erecting bracket and the turntable arm when the upper arm of the turntable turns to ±50° in azimuth, Due to the difficulty of not being able to conduct azimuth scanning tests outside the range of ±50°, adhering to the design concept of easy-to-use operation, an airborne radome azimuth and large-angle test auxiliary device was designed and manufactured. See Figure 1 ~ Figure 4 . When in use, connect the flat-panel receiving antenna 5 and the waveguide adapter 4 with 4 bolts, place the connected assembly in the groove of the large-angle adjustment piece 1 with scale indication, and connect the waveguide adapter 4 with two screws. The fixed cover pla...

Abstract

The invention belongs to the field of performance testing for radomes, and especially relates to an airborne radome azimuth wide-angle testing assistance device. The invention discloses technical dataof the airborne radome electrical performance azimuth wide-angle scanning and testing assistance device, and gives a detailed account on the application and adjustment process of the assistance device in radome electrical performance testing. The advantages lie in that the assistance device can reliably complete radome azimuth wide-angle electrical performance testing, is easy to adjust and doesnot need to perform transmitting and receiving antenna electrical axis alignment after adjustment, the assistance device is simple to install and convenient and efficient in use, and the testing efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the field of electrical performance testing of radome, in particular to an auxiliary device for large-angle testing of airborne radome. Background technique [0002] In order to ensure the integrity of the radome azimuth scanning, the radome azimuth large-angle test auxiliary device is one of the necessary functions in the radome electrical performance test. In the electrical performance test of the radome, the relative position of the radome and the antenna should completely simulate the actual installation position on the aircraft. The problems existing in the current work are analyzed as follows: In order to ensure that the relative position of the antenna and the canopy meets the actual installation position, the laboratory adopts the radome to be erected on the turntable, and the radome is driven by the azimuth rotation of the turntable to rotate, and the antenna is erected on the turntable The cement base at the rear rem...
