Abstract
A system for controlling a wing sweep angle includes: main wings rotatably connected to a fuselage; and a control assembly configured to control a sweep angle of the main wings, where the control assembly is further configured to deploy or retract the main wings, and fix the main wings at two or more sweep angles.
Claims23
A system for controlling a wing sweep angle, the system comprising:
- main wings rotatably connected to a fuselage;
- and
- a control assembly configured to control a sweep angle of the main wings,
- wherein the control assembly is further configured to deploy or retract the main wings, and fix the main wings at two or more sweep angles, and
- wherein the control assembly comprises:
- a link assembly connected to the main wings;
- a first actuator;
- a first rod connected to the link assembly and elastically installed in the first actuator;
- a first elastic lock installed in the first actuator and configured to restrict a movement of the first rod;
- a second actuator fixed to the fuselage;
- a second rod installed in the second actuator and connected to the first actuator, the second rod being configured to move with the first actuator;
- a second elastic lock configured to restrict a movement of the second rod;
- and
- a trigger actuator comprising a trigger configured to release a restriction of the second rod.
