Abstract

The invention discloses a three-degree-of-freedom turning frame system applied to a dynamic flight simulator of a helicopter. A rolling and turning frame is connected with a manned cabin in a rotatable manner to realize pitching motion of the manned cabin; a yawing frame is connected with the rolling and turning frame in a rotatable manner to realize rolling and turning motion of the manned cabin;the yawing frame is connected with the tail end of a turning arm of a centrifugal machine through a bearing to realize yawing motion of the manned cabin, so that the manned cabin rotates in three degrees of freedom in a centrifugal field; the rolling and turning frame and the manned cabin as well as the rolling and turning frame and the yawing frame are respectively connected through expansion sleeves; furthermore, a power system is mounted on a shaft sleeve; the shaft sleeve is mounted in a shaft hole. The structural cooperation is relatively easy to mount and dismount; due to the design ofa round table structure on a pin shaft and a conical surface in the shaft hole, the pin shaft can be automatically guided and located during mounting, and the cooperation precision is high.

Description

technical field [0001] The invention belongs to the technical field of helicopter dynamic flight simulation, and in particular relates to a three-degree-of-freedom rotating frame system used for a helicopter dynamic flight simulator. Background technique [0002] The three-degree-of-freedom rotating frame system of the helicopter dynamic flight simulator is installed at the end of the rotating arm of the centrifuge platform, which can realize arbitrary attitude changes in space in a continuous overload environment, and is used for flight simulation training, especially flight illusion training. Flying illusion, that is, the pilot cannot correctly perceive the position, movement and attitude of the aircraft or himself, and it is easy to cause wrong operation and lead to flight accidents. In order to reduce the illusion of flight, an effective method is to simulate through a ground simulator to improve the pilot's cognition and achieve the purpose of overcoming the illusion of...
