Embodiment Construction

[0025] see figure 1 — Figure 5 , the device includes a first wing, a second wing, a third wing, a fourth wing, a coaxial ducted fan duct, a coaxial ducted fan upper blade, a coaxial ducted fan lower blade, Coaxial ducted fan hub, coaxial ducted fan bracket, tail deflector, tumbler system, carbon rod, battery, surface hole of tumbler system, center body, landing gear, motor.

[0026] The upper blade of the coaxial ducted fan and the lower blade of the coaxial ducted fan have the same airfoil shape; the upper blade of the coaxial ducted fan and the lower blade of the coaxial ducted fan pass through the central body and the coaxial ducted fan blade The hub is connected, the center body is divided into inner and outer sides, and there are beads between the two sides, the blades are consolidated with the outer side, and the hub is consolidated with the inner side. The upper blade of the coaxial ducted fan and the lower blade of the coaxial ducted fan rotate at the same speed, an...

Abstract

The invention proposes an aircraft that combines a tumbler system and a coaxial ducted fan. The tumbler aircraft adopts all-electric drive, and has both vertical take-off and landing, hovering and low-speed forward flight performance; the use of a coaxial ducted fan can improve the performance of the aircraft. the vertical take-off and landing efficiency; the use of the tumbler system can increase the wind resistance and self-stabilization performance of the aircraft; a tail deflector is installed inside the industrial shaft ducted fan duct, which can be used to control the airflow direction of the ducted fan, thereby ensuring the aircraft It has low-speed forward flight performance; certain small holes are arranged on the surface of the tumbler system located at the lower part of the coaxial ducted fan. When it is subjected to a crosswind, the air flow will flow through the small holes, which can reduce the force and effect of the crosswind on the tumbler system. The swing amplitude of the tumbler system during the self-stabilization process after being affected by the crosswind; the aircraft of the present invention adopts the method of combining the tumbler system and the coaxial ducted fan, which increases the self-stability and anti-crosswind capability of the aircraft and reduces the control cost of the aircraft.

Description

technical field [0001] The invention relates to the field of aeronautical aircraft design, in particular to a tumbler aircraft, which combines a traditional tumbler system with a coaxial ducted fan and has vertical take-off and landing, hovering and low-speed forward flight performance. Background technique [0002] The coaxial dual-rotor has two upper and lower rotors that rotate around the same theoretical axis, one is positive and the other is reverse. Since the two rotors turn in opposite directions, the torques generated by the two rotors will balance each other in the flight state with the same heading, thereby ensuring the aircraft's Stability; the coaxial dual rotors can generate unbalanced torque through the so-called collective pitch difference of the upper and lower rotors, thereby realizing the control of the aircraft. The coaxial dual rotors are both the lifting surface and the vertical, horizontal and heading control surfaces during the flight of the aircraft. ...
