Telescopic foldable rotor wing

Abstract

The invention discloses a telescopic foldable rotor wing. The telescopic foldable rotor wing comprises outer blade sections, inner blade sections, a big disc, internal stoppers of a small disc, the small disc, slide grooves, propeller hubs, sliding blocks, a main shaft, steering engines, a cowling, a motor, limit rollers and plug pins. According to the telescopic foldable rotor wing disclosed by the invention, the function of perpendicularly ascending and descending is well realized, the time for extending and retracting is short, the speed of level flight is high, and the big disc can generate ascending force during the level flight. The telescopic foldable rotor wing disclosed by the invention conforms to the requirements for the strength, the rigidness, the air operation, the weight, the fatigue life and the like of the structural design of an aircraft rotor wing, and does not generate negative influences on the use and the maintenance of aircrafts.

Description

technical field [0001] The invention belongs to the field of composite aircraft rotor structure design, and in particular relates to the design of a composite aircraft rotor contraction and folding mechanism. Background technique [0002] The concept of composite aircraft is proposed to integrate the superior performance of helicopters and fixed-wing aircraft. However, the coexistence of rotors and fixed-wings will generally cause greater aerodynamic interference. In general, compound aircrafts pursue the vertical take-off and landing of helicopters and the high-speed cruising performance of fixed wings. According to this idea, the design of compound aircraft generally reduces the aerodynamic resistance of the rotor during high-speed cruising. The interference problem of rotor and fixed wing is the problem that compound aircraft must overcome when cruising at high speed. [0003] At present, the design of composite aircraft is still in the exploratory stage, and the problem...

AI Technical Summary

Problems solved by technology

[0003] At present, the design of composite aircraft is still in the exploratory stage, and the problem of rotor interference has not been well answered

However, only reducing the rotor radius will cause the aircraft's rotor paddle to be loaded too much, and there will be a series of problems, such as high rotation speed, etc.
