Problems solved by technology

However, even if the rotor shaft rotates to a horizontal state and flies in the form of a propeller aircraft, due to the shape and size limitations of the rotor itself and the characteristics of the propeller aircraft itself, its speed is still relatively low compared to the speed of a jet engine aircraft

Abstract

The invention belongs to the field of flight products, and specifically discloses an aircraft with retractable rotors, which includes an aircraft body, rotors and a jet engine, the jet engine is installed at the tail of the aircraft body, and the rotors are rotatably installed on On both sides of the aircraft body, the rotor includes a rotor shaft, rotor blades and a base, the base includes a fixed seat and a rotating part, the rotating part is movably connected with the fixed seat, and the rotor blade is connected to the rotating part through a rotary pin Connect; Simultaneously the invention also discloses the flight mode of this aircraft. The rotor of the aircraft disclosed by the invention can be rotated to be parallel or perpendicular to the horizontal plane during flight, and the blades of the rotor can be expanded and retracted, which not only retains the vertical take-off and landing and hovering capabilities of ordinary tilting aircraft, but also overcomes the need The wind resistance generated by the rotor blades during the process increases the flight speed of the aircraft.

Description

technical field [0001] The invention belongs to the field of flight products, and in particular relates to an aircraft with retractable rotors and a flight method. Background technique [0002] Tilting rotor aircraft is a new type of aircraft that integrates fixed-wing aircraft and helicopters. It not only has the ability to take off and land vertically and hover in the air, but also has the ability to cruise at a higher speed like a propeller aircraft. The tilt rotor aircraft has a unique set of rotatable rotor tilt system components, which are generally installed at the tip of the two wings similar to the wings of a fixed-wing aircraft. When taking off and landing vertically, the rotor axis is perpendicular to the ground, and it is in a horizontal helicopter flight state. , and can hover in the air, fly back and forth and sideways. After the tilt-rotor aircraft takes off and reaches a certain speed, the rotor shaft can be tilted forward at an angle of 90° and is in a hori...
