Vertical take-off and landing double-body aircraft

Abstract

The invention relates to the technical field of aviation aircrafts, in particular to a vertical take-off and landing double-body aircraft. The vertical take-off and landing double-body aircraft is characterized in that the aircraft comprises a right aircraft body and a left aircraft body which are symmetrically arranged, the front ends of the right aircraft body and the left aircraft body are connected through a front canard, the rear ends of the right aircraft body and the left aircraft body are connected through a horizontal tail, an undercarriage is arranged on the lower portion of the right aircraft body, a vertical tail is arranged on the rear portion of the right aircraft body, an engine compartment is arranged on the upper portion of the right aircraft body, an air inflow channel isarranged at the front end of the engine compartment, engine jet pipes are arranged at the front end and the rear end of the engine compartment, and an aircraft power system is arranged in the enginecompartment and connected with blades through a power transmission mechanism. Through design of the symmetrically-arranged double aircraft bodies and fixed wings / rotors capable of rotating oppositely,the problem existing in the main blade torque is solved; and turbine engines capable of being switched between a turbo-shaft mode and a turbofan mode are adopted, the optimal thermodynamic cycle in different flight states is achieved, and the highest level flight speed of the aircraft is increased.

Description

technical field [0001] The invention relates to the technical field of aviation aircraft, in particular to a vertical take-off and landing catamaran aircraft. Background technique [0002] More than a hundred years ago, the Wright Brothers' manned powered aircraft successfully flew. Until today, aviation technology has developed rapidly, and various new aircraft concepts continue to emerge, which have played a huge air superiority in wars. It has played a huge role in promoting the development of the national economy and has greatly changed people's way of life. Fixed-wing aircraft must rely on the runway to take off and land, while helicopters are not subject to this restriction, but the disadvantage is that its maximum cruising speed is usually 300km / h due to the limitation of rotor speed. If there is an aircraft that can take off and land helicopters and high-speed fixed-wing cruise advantages, it will have important uses in military and civilian fields. [0003] Curren...

AI Technical Summary

Problems solved by technology

The problem is that the coaxial anti-propeller dual-rotor system has a complex structure, low safety, and limits its maximum level flight speed

[0007] There are many technical solutions for vertical take-off and landing high-speed cruise aircraft in the prior art, but most of them have: (1) the low efficiency of the rotatable nozzle during vertical take-off and landing or the maximum speed limit caused by the rotor in level flight; (2) There are many adjustment and control mechanisms, and the control is complex; (3) When balancing the torque of the main propeller, coaxial anti-rotor dual rotors are often used or symmetrical layouts are used but tilt rotors are used, which makes the structure complex and reduces safety.
