Torque self-balancing three-ducted-fan bionic aircraft

Abstract

A torque self-balancing three-ducted-fan bionic aircraft mainly comprises a spherical man-carrying cabin, a flight lift force bottom board, bionic wings, a bionic tail, a transitional aircraft frame,three self-balancing ducted fans / propeller devices, a safety protection system and a power automatic control system. The top and the bottom of the rotatable spherical man-carrying cabin are connectedwith the front end of the transitional aircraft frame, and the front end of the bionic tail is connected with the rear end of the transitional aircraft frame; the bionic wings are fixedly connected tothe top of the transitional aircraft frame, and the flight lift force bottom board is fixedly connected to the bottom of the transitional aircraft frame; and two of the three self-balancing ducted fans / propeller devices are fixed to the bionic wings, the other self-balancing ducted fan / propeller device is fixed to the center line of the head and the tail of the bionic tail, and the three self-balancing ducted fans / propeller devices and the safety protection system are all electrically connected with the power automatic control system. The aircraft is simple in structure, capable of verticallytaking off and landing and using an aircraft body to supply lift force, low in energy loss, good in applicability, low in manufacturing cost and high in safety, and meanwhile the self-balancing problem of the three ducted fans is effectively solved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a torque self-balancing three-duct fan bionic aircraft. Background technique [0002] At present, the development of aircraft is changing with each passing day. Various types of aircraft are widely used in aerial photography, agriculture, plant protection, Selfie, express transportation, disaster rescue, observation of wild animals, monitoring, surveying and mapping, news reports, power inspection, disaster relief, film and television shooting, military and other fields. However, at present, aircraft in various fields mainly use large aircraft and small or micro unmanned aircraft, and there are few small manned aircraft for ordinary people to experience flying and travel in daily life. Existing aircraft can be roughly divided into fixed-wing aircraft and gliders, rotary-wing helicopters and rotorcraft, flapping-wing aircraft, and tilting-rotor aircraft. Fixed-wing aircraft and gl...

AI Technical Summary

Problems solved by technology

Existing aircraft can be roughly divided into fixed-wing aircraft and gliders, rotary-wing helicopters and rotorcraft, flapping-wing aircraft, and tilting-rotor aircraft. Fixed-wing aircraft and gliders generally require long take-off and landing runways and are expensive, and are generally not suitable for It is the first choice for ordinary people to do flying experience and daily life travel; the flight noise and vibration of rotorcraft and rotorcraft are relatively large, and the operation of helicopters is complicated, which is not conducive to daily life travel and flying, and the flying experience is extremely poor; orthopter is a bionic aircraft. Smaller in weight, it is more suitable for use as a drone; the tiltrotor combines the characteristics of fixed wings and helicopters as a new type of aircraft. Although it has many advantages, its high cost and complicated operation are not suitable for ordinary people's daily use and flying experience

[0003] Secondly, the design schemes of aircraft as vehicles emerge in endlessly, especially the design of multi-rotor and ducted blade manned aircraft has been paid attention to by the majority of scientific and technological work, but there are still many deficiencies in this type of technology. For example, Chinese patent CN201521115297.2 provides A multi-rotor manned aircraft, comprising an aircraft body with a manned accommodation cavity and at least three arms arranged on the aircraft body, each arm is provided with two upper and lower propellers driven by a driving device, its technology It provides a tool for manned aircraft, but there are still some problems. First, its preferred solution is four arms, and it needs to be symmetrically arranged to achieve the self-balancing of the whole machine by offsetting the torque between the two arms. It is difficult to ensure torque balance with three arms; second, the propellers used in the arms have relatively large aerodynamic noise, which is relatively large in terms of carrying people or external influences, and the comfort experience is poor; third, it has no safety settings. The system, in the event of a power failure or a more urgent situation, cannot guarantee the safety of the people on board, and is not suitable for ordinary people's flight experience and comfortable life travel

In addition, how to make the flight performance of the tilting trirotor aircraft more stable and torque balance is still a hot spot in the academic circles in recent years. Some people have proposed to solve the problem by calculating the length of the moment arm and matching the rotation speed and adjusting the complex calculation algorithm, but it is still not ideal.
