Problems solved by technology

This kind of tilt rotor aircraft has a relatively compact structure and a small footprint when parked, which solves the negative impact of the wings on the main rotor when hovering, and allows a large center of gravity when hovering, and can be used for conventional operations like ordinary aircraft. taxi

Abstract

The invention relates to a tilt rotor aircraft adopting parallel coaxial dual rotors, which comprises a fuselage, wings, an empennage, a pitch control scull system, a landing gear, a power and fuel system, a transmission system, a rotor system, a rotor nacelle and a tilt system, wherein the wings are arranged at the center section of the fuselage; the empennage and the pitch control scull system are arranged at the tail of the fuselage; the landing gear is positioned at the belly of the fuselage; the power and fuel system is arranged inside the center section of the fuselage and is connected with the rotor system and the pitch control scull system through the wings and the transmission system in the fuselage; the rotor system is arranged on the rotor nacelle at the tip of the wings; partial wing which is fixedly connected with the rotor nacelle and simultaneously can tilt is arranged at the inner side of the rotor nacelle; and the tilt system is arranged in the wings and is connected with the rotor nacelle and the partial wing which can tilt. The tilt rotor aircraft is mainly characterized by adopting the pitch control scull system, the parallel coaxial dual rotors and the partialwing which can tilt to realize flight status transformation and conventional taxiing and landing, thereby improving the forward speed and the propulsive efficiency.

Description

(1) Technical field: [0001] The invention relates to a tilt rotor aircraft, in particular to a tilt rotor aircraft adopting parallel coaxial double rotors. The invention belongs to the technical field of vertical take-off and landing aircraft and aviation vehicle design. (two) background technology: [0002] In order to design an aircraft that has both the vertical take-off and landing performance of a helicopter and the high-speed, long-range performance of a fixed-wing aircraft, humans have proposed various vertical take-off and landing aircraft, including compound helicopters, equipped with thrust vectoring engines or Lift powered jet aircraft, rotary wing aircraft, tilt ducted propeller aircraft, tilt rotor aircraft, etc. For specific information, please refer to the paper published by American scholar Rob Ransone: An Overview of VSTOLAircraft and Their Contributions (An Overview of VSTOLAircraft and Their Contributions, paper number: AIAA-2002-5976). [0003] Due to i...
