Description

A kind of Connected wing aircraft of collapsible wing with four-point undercarriage

Technical field

The utility model is related to aircraft circles, the connection wing of specifically a kind of collapsible wing with four-point undercarriage Aircraft.

Background technology

Existing aircraft size is substantially immutable, is substantially completely fixed.But, sometimes for change in reality The size of aircraft, such as storage and when carrier in certain space, it is desirable to which aircraft is tried one's best the space reduced and occupy Area, to store and transport more aircrafts, if the size of aircraft can not reduce, and the space of transport and storage is difficult to increase Plus, that will certainly reduce the quantity of storage and transport, reduce the efficiency of storage and transport, increase the cost of storage and transport.Example Such as, on aircraft carrier, for carrier-borne more aircrafts, it is desirable to which aircraft is tried one's best and reduces the space occupied, if carrier-borne aircraft can not subtract Small size, will certainly cause to cut down to the maximum carrier-borne aircraft quantity of aircraft carrier.

The existing aircraft that can change size, mostly by the way of folded wing and telescopic wing.Although this two The mode of kind can reduce the size of aircraft, but all employ the mode for changing wing shapes.This mode needs to be set on wing Section or gap are put, makes wing realize shrinking.This mode destroys the shape of wing, will certainly influence the pneumatic cloth of wing Office, causes stability during aircraft flight to be affected；In addition, if this mode of long-term use, will certainly make the machine of aircraft The wing receives a certain degree of destruction, increases maintenance cost.For example, destroying 15 carrier-borne aircrafts, reduced by the way of folding winged Machine size, the mode of this destruction wing shapes will certainly influence the aerodynamic arrangement of aircraft, and increase maintenance cost.

The undercarriage of existing aircraft is general using a main support straight up, and maintains main support stabilization each In 90 degree of diagonal brace, although this undercarriage can ensure the stabilization of undercarriage, when undercarriage is subject to come from one of them During the power in diagonal brace direction, the diagonal brace of only main support and the force direction of that stress；In addition, when undercarriage is subject to power straight up When, then the only main landing gear of stress.Under both of these case, the power suffered by undercarriage can not be decomposed effectively, inevitable Can reduce the service life of undercarriage, and a certain degree of damage is caused to the installation position of undercarriage.

Therefore, a collapsible wing is designed to overcome the shortcomings of above-mentioned technology, reduces aircraft size, undercarriage is received A kind of significant Connected wing aircraft of collapsible wing with four-point undercarriage of power discomposing effect, exactly inventor is to be solved Problem.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of collapsible wing and is risen and fallen with four-point The Connected wing aircraft of frame, can realize that shrinking wing reduces aircraft size, and undercarriage stress discomposing effect is notable.

The utility model solves the technical scheme that its technical problem used：A kind of collapsible wing rises with four-point Fall the Connected wing aircraft of frame, and it includes：Aft swept wings, extension horizontal tail, six prism fuselages, vertical fin, winglet, propeller, four Point type undercarriage, wing attachment means, horizontal tail attachment means, wing horizontal tail attachment means, slide rail；The six prisms inboard Slide rail is provided with, described six prisms inboard head one end is provided with wing attachment means, the six prisms inboard machine Tail one end is provided with horizontal tail attachment means, and the six prisms fuselage outer side tail top is provided with vertical fin, the six prisms fuselage Outside tail end is provided with propeller, and the wing attachment means connect aft swept wings, the aft swept wings and extension Horizontal tail is hinged by wing horizontal tail attachment means, the extension horizontal tail outside connection winglet, and the extension horizontal tail lower section sets Four-point undercarriage is equipped with, the extension horizontal tail connects horizontal tail attachment means, the horizontal tail attachment means connecting sliding rail；

The four-point undercarriage includes connection Four-fork axle in Four-fork bearing, undercarriage support, wheel, the wheel Hold, the Four-fork bearing connects undercarriage support.

Further, the six prisms fuselage, on four sides in addition to top and bottom, has for convenience of wing motion Reserved groove.

The beneficial effects of the utility model are：

1. the utility model connects aft swept wings by using wing attachment means, and aft swept wings lead to extension horizontal tail Cross wing horizontal tail attachment means to be hinged, extension horizontal tail connection horizontal tail attachment means, horizontal tail attachment means are fixed on the knot on slide rail Structure, realizes the contraction of wing, effectively reduces the size of aircraft.

2. by using four-point undercarriage, each branch for realizing the power suffered by undercarriage effectively divides the utility model Solution.
