Abstract

The utility model relates to a flapping-wing aircraft and aims at overcoming the defects that prior flapping-wing aircraft imitates the flying principle of birds, has complicated structure large energy consumption and slow flying speed. For the aircraft, a wing flap is arranged above the fuselage through a fixed frame; a transmission system, a wing-turning device and a retractable device are arranged in the wing flap; a wing with a retractable fan shape is arranged beside the wing flap. Therefore, the wing acquires sufficient lifting force and high speed so that the aircraft can independently accomplish vertical take-off, landing, forward flight, backward flight, turning and horizontal flight without deviation. The aircraft can achieve catapult parachuting; the device has flying flexibility and reliability as well as practicality.

Description

Ornithopter

Technical field

The utility model relates to a kind of aircraft, relates in particular to a kind of ornithopter.

Background technology

It imitates the open-and-close mechanism that birds swat wing flight theory design fuselage, wing, driving engine, flapping wing mechanism, rotor mechanism and wing Chinese patent 94228552.2 disclosed " ornithopter ", its complex structure, the energy that equipment expends is big, and flying speed is slow.

Summary of the invention

The utility model provides a kind of ornithopter that mechanical energy is rationally utilized.

The utility model is realized by the following technical solutions:

By fixed mount the wing fermented soya beans, salted or other wise is set at body upper, transmission system, rotor mechanism and open-and-close mechanism are set in the wing fermented soya beans, salted or other wise, wing fermented soya beans, salted or other wise side is provided with wing, and it is capable of opening and closing fan-shaped that wing is.

For better effect: it respectively is provided with a wing to the hatching line two ends wing fermented soya beans, salted or other wise.

Body upper is symmetrical arranged two fixed mounts and appended wing thereof.

The rib that the wing both sides are provided with connects the support at middle part by ala.

Ala is by the flaabellum shape of minor radius to long radius with the end that the rib direction extends to rib from wing fermented soya beans, salted or other wise end.

The utility model has changed the reciprocating type wing formula operation scheme of swatting of the bionic birds of aircraft in the past, and adopt the rotor blade folding to reach the mode of motion of swatting air, can improve its flight efficiency greatly like this, its principle of work is: two fixing wings of fixed mount are in the different states that close of opening on the perpendicular line of vertical fuselage under the wing fermented soya beans, salted or other wise rotates separately, 90 ° each other, make synchronous backward and rotate.When wing goes to fuselage perpendicular line inside, rib is closed under the control of wing fermented soya beans, salted or other wise open-and-close mechanism, ala is folding, support, rib, ala folds overlapping to a line, form minimum windward side, air resistance is very little, and when the wing rotation exceeded outside the fuselage perpendicular line, rib opened, the ala diastole is opened, the wing windward side is big, and ala bounces air, and the wing both sides produce powerful difference of pressure, thereby make wing obtain sufficient lift, fast speeds has the alerting ability and the reliability of flight, changes bowing of wing fermented soya beans, salted or other wise, the elevation angle, just can make aircraft finish vertical rising, fall, before fly, after fly, flare maneuvers such as turning, change the direction angle of wing fermented soya beans, salted or other wise, just can make aircraft finish adherent taking off vertically, left, right horizontal flight.If contrast with helicopter, helicopter owing to rotor in fuselage both sides operating speed difference, inconsistent with air movement speed, fuselage has deflection, and the utility model is consistent with air movement speed owing to two wings, and deflection does not take place during flight; The wing of helicopter covers its whole fuselages and makes its ejection failure parachute jumping, and its vertical space micropodia that occupies body upper can ejection bailout perpendicular to fuselage folding wing for wing of the present utility model, and this structure also attach simple in structure, practicable advantage.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model one structural representation.

The specific embodiment

See Fig. 1, above fuselage 1, be symmetrical arranged two fixed mounts 2 and appended wing thereof.The wing fermented soya beans, salted or other wise 3 that fixed mount 2 connects on the wing, transmission system, rotor mechanism and open-and-close mechanism are set in the wing fermented soya beans, salted or other wise 3, it respectively is provided with a wing to the hatching line two ends wing fermented soya beans, salted or other wise 3, it is capable of opening and closing fan-shaped that wing is, support 42 in the middle part of the rib 4 that the wing both sides are provided with connects by ala 41, ala 41 is by the flaabellum shape of minor radius to long radius with the end that rib 4 directions extend to rib 4 from wing fermented soya beans, salted or other wise 3 ends.Wing on two fixed mounts 2 is in different opening and closes state on the perpendicular line of vertical fuselage, 90 ° each other, make synchronous backward and rotate.When a side wing went to fuselage 1 perpendicular line inside, rib 4 was closed under the control of wing fermented soya beans, salted or other wise 3 open-and-close mechanisms, and ala 41 is folding, support 42, rib 4, ala 41 fold overlapping to a line, form minimum windward side, and air resistance is very little, when the wing rotation exceeds outside fuselage 1 perpendicular line, rib 4 opens, and ala 41 diastoles are opened, and the wing windward side is big, ala 41 bounces air, the wing both sides produce powerful difference of pressure, thereby make wing obtain sufficient lift, fly in blue sky.
