Problems solved by technology

In addition, during the daily maintenance process, it is easy to cause accidental injury to the head of the personnel.
When performing parachute training, the tail brace is used as a protruding device on the tail beam, and there is a risk of "hooking" on the lead parachute of the parachute (such as figure 2 shown)

Abstract

The invention belongs to the technical field of structural design of helicopters, and discloses an automatic retractable helicopter tail boom and a using method thereof. The automatic retractable helicopter tail boom comprises a driving transmission limiting mechanism, a buffering mechanism, a base assembly, an upper connecting assembly and a lower connecting assembly; the driving transmission limiting mechanism is connected with the upper end of the buffering mechanism through the upper connecting assembly, the base assembly is connected with the lower end of the buffering mechanism through the lower connecting assembly, the structure is simple, using and maintaining are convenient, and the safety coefficient is high.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and in particular relates to an automatically retractable helicopter tail brace and a use method thereof. Background technique [0002] Helicopter tail brace refers to the strut below the helicopter tail boom (such as figure 1 shown in middle E), used to prevent the helicopter tail boom, tail rotor, etc. from being damaged by the rearward tilt of the helicopter's center of gravity. The helicopter tail braces used in the prior art are only installed under the tail of the helicopter, and most of them have simple structures. And it is a fixed structure. [0003] At present, the tail braces used on domestic helicopters are mechanical springs or elastic block structures, which are fixed and cannot be retracted, and rely on deformation to generate support. At this stage, the pre-flight inspection and maintenance can only rely on visual inspection, which cannot guarantee the reliab...
