Abstract

The invention relates to the field of surface pressure measurement of rotor blades of helicopters, and relates to a horizontal tail wing box of a helicopter. The horizontal tail wing box comprises a front beam, a rear beam and two reinforcing ribs formed by performing laminating on carbon fiber fabric and forming a framework of the horizontal tail wing box of the helicopter, an upper skin and a lower skin formed by performing laminating on the carbon fiber fabric and used for forming a complete wing box body, and an upper connector and a front connector formed by performing laminating on the carbon fiber fabric. The horizontal tail wing box is small in weight, and simple to assemble, and as the front connector, the front beam and the rib adopt integrated design, the upper connector and a rib web adopt integrated design, the power transmission route is direct, the configuration is simple, and the horizontal tail wing box is convenient to manufacture.

Description

technical field [0001] The invention relates to the field of structural design of a helicopter flat tail box, in particular to a helicopter flat tail box. Background technique [0002] The helicopter flat tail box is located at the tail of the helicopter, and its weight has a great influence on the center of gravity of the whole aircraft. If the weight of the tail makes the center of gravity fail to meet the expected requirements, it is necessary to increase the balance counterweight or adjust the onboard equipment, which will affect the performance of the aircraft by increasing the waste weight . [0003] The existing helicopter flat tail box is mainly made of metal structure, and the beams, webs, and joints are designed separately, and then connected by connectors, which not only affects the weight reduction effect of composite materials, but also has weak integrity. Disadvantages such as heavy weight, long assembly cycle, and high manufacturing cost. Contents of the in...
