Embodiment Construction

[0062]The technical scheme of the present invention stipulates: along the aircraft of the present invention, from the nose to the tail is the longitudinal axis of the aircraft of the present invention. Along the aircraft of the present invention, from the left wing to the right wing is the horizontal axis of the aircraft of the present invention. Along the aircraft of the present invention, from the nose to the belly is the vertical axis of the aircraft of the present invention. The three axes are perpendicular to each other, and the intersection point of the three axes is the design center of gravity of the aircraft. Such as Figure 1 The power distribution system of the present invention is as Figure four shown. The engine transmits the torque to the main drive gear 18, the main drive gear 18, the drive gear 18 meshes with the differential gear 19, drives the differential main drive gear 19, and the differential main drive gear 19 is mounted on the differential case , t...

Abstract

The invention discloses a double contra-rotating rotor wing airplane with a foldable empennage. The foldable empennage can serve as an elevating rudder and a rudder of the airplane and also can be used as a landing gear of the airplane. The double contra-rotating rotor wings of the airplane are characterized in that power is transmitted to the two rotor wings through a differential mechanism and the torque is controlled through brake systems mounted on rotor wing transmission shafts and transmission sleeve shafts. The airplane disclosed by the invention can fly in a fixed wing airplane state and a helicopter state; the fixed wing airplane mode and the helicopter mode can be flexibly switched; the airplane has the advantages of hovering function, relatively high speed, large voyage, energy conservation, environmental friendliness and safety.

Description

technical field [0001] The invention relates to a counter-rotating double-rotor aircraft with fixed wings that can change the angle and a foldable tail. Especially through the coaxial counter-rotating dual-rotors, the fuselage, the fixed wings, flaps, ailerons, and foldable tails on the fuselage, a pair of co-axial counter-rotating dual-rotors, and the blade pitch The torque conversion control system and power control system, the engine, and the operating system are composed. Background technique [0002] Traditional aircraft are generally divided into two categories: fixed-wing aircraft and helicopter aircraft. Among them, fixed-wing aircraft is divided into propeller aircraft and jet aircraft according to the propulsion mode of the aircraft. Jet aircraft can be divided into turbojet, turbofan, turboshaft, turboprop, ram, cylinder piston and so on according to the working mode of the engine. The general characteristics of fixed-wing aircraft are fast speed, high energy-s...
