Abstract

The invention belongs to the field of helicopter structural design, and discloses an adjustable helicopter side end plate structure which comprises a rudder, a side end plate assembly and a steering engine pull rod. The side end plate assemblies are connected to the two ends of the horizontal tail and are perpendicular to the horizontal tail. The rudder is mounted behind the side end plate; the steering engine pull rod is connected with the rudder and used for driving the rudder to rotate. The side end plate can be adjusted by controlling the rudder, the operation is simple, and the universality is strong; the device is simple in structural form, direct in force transmission path, light in weight, low in processing and manufacturing cost and convenient to install.

Description

technical field [0001] The invention belongs to the field of helicopter structure design, in particular to an adjustable helicopter side end plate structure. Background technique [0002] The main function of the helicopter tail side end plate is to maintain the balance and flight state of the helicopter together with the horizontal tail and vertical tail when the helicopter is flying, so the design of the side end plate directly affects the flight performance of the helicopter. [0003] At present, the tail end plates of domestic helicopters are mainly fixed and non-adjustable structures. The disadvantages are: the attitude cannot be adjusted at any time to maintain balance according to the flight state of the helicopter, and it is not suitable for helicopters with complex flight state requirements. Contents of the invention [0004] Purpose of the present invention: In order to meet the requirements of maintaining the flight balance and flight state of the helicopter at ...
