Abstract

The invention discloses an external wing transition beam, which belongs to the technical field of aircraft structure design. It includes a vertical transition beam (1) and two horizontal transition beams (2), one end of the vertical transition beam (1) is fixed at the lower wall plate of the wing, and the two horizontal transition beams (2) are symmetrically distributed on At the other end of the vertical transition beam (1), grooves are arranged on the horizontal transition beam, and the cross section of the vertical transition beam (1) is streamlined. The external wing transition beam structure of the invention can meet the requirements of the mounted equipment, and the structural strength meets the design requirements, and at the same time, it will not affect the lift and drag of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of aircraft structure design, and in particular relates to an external wing transition beam. Background technique [0002] In the current aircraft development, according to the modification requirements of the aircraft, it is necessary to mount a certain amount of equipment and instruments on the lower part of the wing. For this reason, it is necessary to design a transition beam structure at the lower part of the wing for mounting equipment and instruments. According to the functions and requirements of the aircraft and combined with the characteristics of the aircraft itself, the structural design of the transition beam needs to meet the following five conditions: [0003] 1) The external transition beam structure can meet the requirements of the mounted equipment; [0004] 2) The external transition beam structure will not affect the lift and drag of the aircraft; [0005] 3) The external transition be...
