Problems solved by technology

When the landing gear door is opened, it can play a role similar to the ventral fin, which can play a positive role in stabilizing the heading. However, when the landing gear door is fully opened, the cavity formed on the skin surface will produce a large resistance

Abstract

The invention belongs to the technical field of aircraft structural design, and particularly relates to a variable-configuration cabin door for enhancing aircraft course stability and a control methodthereof. The variable-configuration cabin door comprises a follow-up inner-layer cabin door, an outer-layer cabin door, a driving mechanism and a locking mechanism. The outer-layer cabin door is arranged on the outer side of the follow-up inner-layer cabin door; the driving mechanism comprises a rotating shaft, a rotating actuator, a first rocker arm and a second rocker arm and can drive the outer-layer cabin door to be opened or closed; the locking mechanism comprises a first locking mechanism body and a second locking mechanism body, the first locking mechanism body can lock the follow-up inner-layer cabin door and the machine body, and the second locking mechanism body can lock the outer-layer cabin door and the follow-up inner-layer cabin door. The heading stability of the tailless layout aircraft can be remarkably improved, the flight performance and maneuverability are effectively improved. Meanwhile, a large cavity is prevented from being formed as much as possible after the cabin door is opened, the cavity resistance generated after the outer-layer cabin door is opened is very small and can be almost ignored, and the aerodynamic characteristics of the aircraft are not affected.

Description

technical field [0001] The application belongs to the technical field of aircraft structure design, and in particular relates to a variable-configuration hatch and a control method for enhancing aircraft heading stability. Background technique [0002] In order to pursue better stealth performance and higher survivability, modern aircraft begin to use tailless layout more and more. Because the tailless layout aircraft has no vertical tail, the directional stability is weak. This problem is more obvious when flying at high speed, and the use of the tailless layout aircraft is also subject to many restrictions. [0003] In the prior art, the way of opening the landing gear hatch has a relatively large auxiliary effect on the heading control of the tailless layout aircraft. When the landing gear door is opened, it can play a role similar to the ventral fin, which can play a positive role in stabilizing the heading. However, when the landing gear door is fully opened, the cavit...
