Abstract

The invention provides an intelligent material driven or mechanical driven aircraft with turnable wings, and the aircraft provided by the invention has the advantages of high speed, long voyage, low oil consumption, capability of VTOL (vertical take-of and landing), and capability of hovering. The aircraft comprises an aircraft body, sectional bending turnable wings, electroactive polymer skins, sheet macro-fiber piezoelectric composite material bars, deformed honeycomb fillers, a reversal platform and variable pitch propeller engines, wherein the two variable pitch propeller engines are symmetrically mounted on the rear edges of the wings, the electroactive polymer skins are taken as wing skins, the sheet macro-fiber piezoelectric composite material bars are arranged on the neutral layers of the wings, the spaces between the wing skins and the sheet macro-fiber piezoelectric composite material bars are filled with the deformed honeycomb fillers, and the reversal platform is placed ata rotary center inside the aircraft body. According to the invention, an intelligent driver is utilized as the driving source for wing turning, and the aircraft has the advantages of light weight, simple mechanism, high efficiency and convenience for maintenance, and can be switched rapidly in flying modes of level flaying and hovering through wing turning.

Description

(1) Technical field

[0001] The invention relates to aerospace technology, in particular to an aircraft with twistable wings. (2) Background technology

[0002] Since the advent of fixed-wing aircraft, it has developed rapidly with the advantages of fast speed and long range. However, the take-off and landing of aircraft must rely on runways or catapults, and because they cannot spin and stop, it is difficult to conduct continuous and uninterrupted reconnaissance of targets. The helicopter-type hovering aircraft does not have this defect, but the disadvantage is that due to the limitation of the rotor, the flight speed is difficult to exceed 300km / h, and the flight range is also relatively short. In recent years, some countries have set off an upsurge, competing to develop a vertical take-off and landing aircraft that combines the performance advantages of fixed-wing aircraft and helicopters. The precise definition of a vertical take-off and landing vehicle (VTOL) is: the ab...
