Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aircraft telescopic wing technology, and in particular relates to an aircraft telescopic wing control device. Background Technology
[0002] With the continuous advancement of aviation technology, the performance requirements for aircraft are also increasing. In the modern aviation field, aircraft need to achieve optimal flight performance and efficiency under various flight conditions.
[0003] Under normal circumstances, when an aircraft is flying at high speed, the winglets increase the drag experienced by the aircraft, which not only greatly reduces the flight speed and has a significant impact on the aircraft's maneuverability, but also consumes more fuel. When the aircraft is flying at low speed, the winglets can effectively improve lift and stability. Fixed winglets are difficult to meet the requirements. Therefore, we propose an aircraft telescopic winglet control device. Utility Model Content
[0004] The purpose of this invention is to provide a control device for retractable winglets of an aircraft. By setting a telescopic section, specifically a limiting block that moves, a bevel gear one rotates accordingly. The bevel gear one drives a rotating shaft one to rotate, which in turn drives a bevel gear two to rotate. The bevel gear two then drives a threaded rod to rotate, which in turn drives two winglets to slide along a slide rail, thereby extending both winglets. This allows for the extension and retraction of the wingspan according to the aircraft's needs, better meeting the aircraft's requirements. It solves the problem that in existing aircraft flying at high speeds, winglets increase drag, significantly reducing flight speed and maneuverability, and consuming more fuel. Furthermore, in low-speed flight, winglets effectively improve lift and stability, a problem that fixed winglets struggle to meet.
