Embodiment Construction

[0011] In the figure, the whole wing rib is divided into the front half section of the wing rib (10) and the second half section of the wing rib (11). An angle limiter (13) is set at the lower part behind the front half of the rib, an angle limiter (15) is set above the second half of the rib, and an angle limiter (14) is set below the second half of the rib. The pull rod (3) and the middle frame (5) connecting the middle frame of the outer wing section respectively pass through the holes (16) of the front and rear two sections of the wing rib of the inner and outer wing section, so that when the crankshaft (2) drives the pull rod (3 ), pull the middle skeleton (5) of the outer wing section, and when the whole wing is lifted, the wing rib will be folded in half with the connection point of the front and rear two sections of the wing rib as the axis. The skin of the wing can be made into a shrinkable fold area at the rear section of the connecting part of the inner and outer wi...

Abstract

A wing of an ornithopter comprises an inner wing section and an outer wing section. A middle frame of the outer wing section and a pull rod connected with the middle frame are respectively threaded through a connecting part of the front section and the back section of wing ribs of the inner section and the outer wing section; when the outer wing section is pulled by the pull rod and the wing is raised, the wing rib is folded with a connecting point as the axis and when the wing swoops, the wing rib is unfolded. An angle limiter is respectively arranged on the front wing rib and the back wing rib to control the folding angle of the front wing rib and the back wing rib so as to lead the wing of the ornithopter to acquire higher rising and flying force when the wing flutters.

Description

technical field [0001] The invention belongs to the field of general aircraft and relates to a wing of an orthopter. Background technique [0002] At present, the research on the orthopter all uses straight wings with hard wings like insects. Although the structure is simple and easy to use, the load capacity is poor. For the whole machine, the ergonomics ratio is poor and the flight stability is not good. Contents of the invention [0003] In order to change the disadvantages of the low efficiency ratio and poor load capacity of the orthopter, the present invention can provide an orthopter wing which is closest to the fluttering state of the wings of birds when they fly. This kind of wing can flap like a bird. When the wing is raised, the outer wing section droops, and the front and rear halves of the wing fold in half. When the wing flutters down, the outer wing section and the front and rear sections of the wing unfold. In this way, a lot of resistance can be reduced ...
