Feather Oropter

Abstract

The invention relates to a wing type ornithopter. The wing type ornithopter comprises a fuselage, flapping wing devices, linking mechanisms and flapping wings, wherein the flapping wing devices are connected with the fuselage from the left side and the right side; the flapping wing devices comprise a pair of flapping wing main shafts; the pair of flapping wing main shafts are connected with the left side and the right side of the fuselage in a pivoting manner, and can flap upwards and downwards relative to the fuselage; the linking mechanisms are capable of driving the flapping wing main shafts to flap upwards and downwards; one ends of the linking mechanisms are movably connected with the flapping wing main shafts; the other ends of the linking mechanisms are connected with the fuselage; the front ends of the flapping wings are connected with the flapping wing main shafts so as to flap upwards and downwards along with the flapping wing main shafts; the tail ends of the flapping wings are connected with the fuselage; the flapping wing main shafts consist of a plurality of movably connected sections. By adopting the wing type ornithopter, requirements of the ornithopter on materials can be effectively reduced, the flapping wing flying efficiency can be improved, and operation simplicity and convenience can be improved.

Description

technical field [0001] The invention relates to an aircraft for bionic bird flapping flight, and in particular to a feather flapping aircraft. Background technique [0002] With the advancement of modern materials, power, and processing technology, especially micro-electromechanical technology (MEMS), it has been possible to manufacture close to practical flapping-wing aircraft. The flapping wing flight has small size, flexibility and high flight efficiency, and can achieve vertical take-off and landing, hovering, forward flight, backward flight, dive, sharp turn and other stunts. Compared with conventional aircraft, the flapping wing aircraft based on the principle of bionics , only a set of flapping wing system can replace propeller or jet engine to provide thrust.

AI Technical Summary

Problems solved by technology

[0003] However, although the current orthopter has been able to achieve better flight and control, there is still a certain gap from practical use, so it still cannot be widely used, but can only be used in some tasks with special requirements, such as the narrow space in urban anti-terrorism. space reconnaissance

[0004] Moreover, the structural design of the flapping wing of the current flapping wing aircraft is a whole. Therefore, the main problems that need to be solved are low aerodynamic efficiency, high power and mechanism requirements, high material requirements and small payload.
