Problems solved by technology
[0002] When the aircraft is flying at high speed in the atmospheric environment, the air rudder plays a very important role in the attitude control of the aircraft. During the whole flight process, the air rudder must always maintain a flexible state of rotation, which requires that the rudder shaft of the air rudder and the cabin body There is a movement gap in the structure, but at the same time, the hot air will enter the mounting seat where the bearing is installed through the gap between the rudder shaft and the cabin, which will affect the running accuracy of the bearing and the rotation of the air rudder, and then affect the flight of the aircraft.

The invention discloses a hot air flow blocking structure. The structure is suitable for the technical field of air rudders. A gap between the inner circumferential surface of a ring cover and a rudder shaft, a gap between the bottom of the ring cover and the top of a blocking ring, a gap between the outer circumferential surface of the blocking ring and the inner circumferential surface of a mounting groove and a gap between the bottom of the blocking ring and the top of a bearing are communicated to form an airflow channel. According to the air rudder, the temperature of hot airflow entering the mounting base for mounting the bearing through a gap between the rudder shaft and the cabin can be blocked and attenuated, and the operation precision of the bearing and rotation of the air rudder are prevented from being affected.
Description
technical field [0001] The invention belongs to the technical field of air rudders, and in particular relates to a hot air flow blocking structure. Background technique [0002] When the aircraft is flying at high speed in the atmospheric environment, the air rudder plays a very important role in the attitude control of the aircraft. During the whole flight process, the air rudder must always maintain a flexible state of rotation, which requires that the rudder shaft of the air rudder and the cabin body There is a movement gap in the structure, but at the same time, the thermal airflow will enter the mounting seat where the bearing is installed through the gap between the rudder shaft and the cabin, which will affect the running accuracy of the bearing and the rotation of the air rudder, and then affect the flight of the aircraft. Contents of the invention [0003] The present invention aims at at least to a certain extent to solve the technical problem that the hot air fl...
