Abstract

The invention belongs to the technical field of aviation and relates to a rotating and connecting structure of an aircraft radome. The rotating and connecting structure mainly comprises a radome (1), a rack wheel (2), a pinion (3), a speed reducer (4), a hydraulic motor (5), a support seat (6), an overturning bearing (7), a transition part (8), a bolt (9), a bolt (10), a bracket (11) and a reinforcer (12). The overturning bearing of an inner gear is arranged in the radome, and a load of the radome is transferred to a bearing inner ring and then transferred to the bracket by virtue of drive of the hydraulic motor, so that a large-size and large-inertia radome rotating function and load transferring are achieved. The rotating and connecting structure is simple, good in force transmission characteristic and light in weight, adopts rotating driving, and adopts a rotating driving, connection and installation method of the aircraft radome. Rotating of the radome can be achieved, the load of the rotating radome is transferred to the bracket, and the problems of large-inertia rotating and load transferring are solved.

Description

technical field [0001] The invention belongs to the technical field of aviation, and relates to a rotation and connection structure of an aircraft radome. Background technique [0002] The radome is a remarkable feature of the early warning aircraft, and it is also a difficulty in development. The radar of the traditional early warning aircraft emits fan-shaped beams from the antenna in the disc-shaped radome, and uses a mechanical rotating base to rotate so that the radar beam can scan and cover a certain airspace, which is called mechanical scanning; this method must wait for the radar antenna to rotate The same target can be continuously tracked after a week or a scanning cycle is completed and the target is captured again. Generally, the radar speed of the early warning aircraft is about 5 to 6 times per minute, that is, 30° to 36° per second. The radome and the antenna are designed as a whole, and when the antenna scans, the antenna and the radome rotate together (rota...
