Abstract

The invention relates to a miniature ornithopter with a wing twisting function and multiple flight motion functions and belongs to the field of miniature ornithopters. A flapping torsional mechanism, an empennage, a fuselage direct-current motor, an empennage supporting rod and an electronic control module are installed on an ornithopter frame body. Wings are connected to torsional panels. An adjusting and steering rotor is connected to a fan motor. An empennage transmission mechanism is connected to the empennage supporting rod. The empennage supporting rod and the empennage are fixedly connected together by an empennage supporting rod fixing structure through screws. The miniature ornithopter has the beneficial effects that the structure is novel, the design structure is simplified, and miniaturization is easy to achieve. The ornithopter can generate larger pushing-up force compared with an aircraft only flapping up and down under the condition that the flapping frequencies are the same, the flight performance of the miniature ornithopter is greatly improved, the ornithopter flies flexibly, the aerodynamic characteristics are improved, the flight efficiency is high, the size is small, the weight is small, practicality is higher, and more flight functions can be achieved.

Description

technical field [0001] The invention relates to the field of a miniature flapping-wing aircraft, in particular to a miniature flapping-wing aircraft with twistable wings and capable of realizing multiple flight functions. Background technique [0002] As a new type of flying robot imitating birds, the micro flapping wing aircraft has the advantages of light weight, small size, flexible flight, high efficiency, etc., and it can also realize relatively complex powered flight. The flapping-wing aircraft flies by flapping its wings during flight. Compared with fixed-wing and rotary-wing aircraft, the flapping-wing aircraft has the characteristics of small take-off space, good maneuverability, ability to hover and high energy utilization. At present, micro-aircraft can be used in the military field to carry out target detection work, accurately transmit information, use its strong concealment characteristics to achieve the purpose of raids, and use its communication function to a...
