Abstract
The present invention discloses a kind of mini foldable unmanned plane, including fuselage, preceding wing and rear wing, and the preceding wing can rotate backward folding, rotation expansion forward；The rear wing can turn folding forward, and rotate backward expansion；Rear is provided with primary control surface in the middle part of preceding wing and rear wing；Fixed fin is slightly provided in the rear wing wing.The unmanned plane is forward and backward wing " lift formula " layout, the preceding wing aircraft above the horizon, rear wing is under aircraft horizontal line.Novel unmanned plane provided by the invention, wing-folding can be got up, compact-sized, be occupied little space, and multiple collapsible unmanned planes are transported to target proximity region using delivery vehicle and are launched；Launching, external environment is complicated, under the unfavorable conditions more than disturbing factor, unmanned plane course-stability in length and breadth, ensure that unmanned plane can be safely unfolded under complicated initial fixed condition, pull-up, reach scheduled stable state.
Description
Technical field
The present invention relates to Flight Vehicle Design, in particular to collapsible unmanned plane.
Background technique
When needing multi rack miniature drone to be jointly acted, the voyage of miniature drone is difficult to meet the requirements, therefore,
Using machine tool as carrier, the deficiency for making up miniature drone voyage is effective solution scheme.In order to allow a frame machine tool can be with
Multi rack miniature drone is carried, miniature drone, which needs to fold, to be put into the equipment of machine tool, thus, it is desirable to using unconventional pneumatic
The unmanned plane of distribution form.
Summary of the invention
The task of the present invention is according to mission payload, one kind being provided and meets pneumatic principle, lift resistance ratio is higher, meets mission requirements,
Guarantee that unmanned plane during flying performance, quality are laid out the novel pneumatic of unmanned plane.
The object of the present invention is achieved like this:
Mini foldable unmanned plane, including fuselage, preceding wing and rear wing, the preceding wing can rotate backward folding, forward
Rotation expansion；The rear wing can turn folding forward, and rotate backward expansion；Rear is arranged in the middle part of preceding wing and rear wing
There is primary control surface；Fixed fin is slightly provided in the rear wing wing.
The unmanned plane is forward and backward wing " lift formula " layout, the preceding wing aircraft above the horizon, rear wing is flying
Under machine horizontal line, the flat shape of the preceding wing and rear wing is approximately rectangle, and rear wing is than preceding chord 0.2m ± 0.1m；
When expansion, the upper counterangle of the forward and backward wing is 2 ° ± 0.5 °, and the established angle of the preceding wing is 3 ° ± 0.5 °, described
Rear wing established angle be 1.5 ° ± 0.5 °.
The fuselage uses elliptic cross-section, both ends ellipsoid correction of the flank shape.
The fixed fin root chord length is identical as rear wing slightly chord length, 15 ° ± 2 ° of the fin sweep,
0 ° to 5 ° of the fixed fin camber angle.
The primary control surface maximum degree of bias is -30 ° to+30 °.
The invention has the following beneficial effects:
Novel unmanned plane provided by the invention, wing-folding can be got up, compact-sized, occupied little space, utilized delivery
Multiple collapsible unmanned planes are transported to target proximity region and launched by tool；Launching, external environment is complicated, more than disturbing factor
Under unfavorable conditions, unmanned plane course-stability in length and breadth, ensure that unmanned plane under complicated initial fixed condition can safely into
Row expansion, pull-up, reach scheduled stable state.
Detailed description of the invention
Wing-folding state Fig. 1 of the invention.
Wing unfolded state Fig. 2 of the invention.
In figure: fuselage 1, preceding wing 2, rear wing 3, primary control surface 4, fixed fin 5.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
See Fig. 1, Fig. 2, a kind of mini foldable unmanned plane of the invention is using " lift formula " layout, including fuselage 1, preceding wing
2 and rear wing 3, preceding wing 1 can rotate backward folding, rotation expansion forward；Wing 3 can turn folding forward afterwards, rotate backward
Expansion；Preceding wing 2 and 3 middle part rear of rear wing are provided with primary control surface 4；Fixed fin is slightly provided in rear 3 wing of wing
5.Preceding wing 2 aircraft above the horizon, rear wing 3 is under aircraft horizontal line, the planar shaped of 2 wing of preceding machine, rear wing 3
Shape is rectangle, and rear wing 3 is than 2 long 0.2 meters of preceding wing；When expansion, the preceding wing 2, rear wing 3 the upper counterangle be 2 °, institute
The established angle for the preceding wing stated is 3 °, and the established angle of the rear wing is 1.5 °.
Fuselage 1 uses elliptic cross-section, both ends ellipsoid correction of the flank shape.5 string chord lengths of fixed fin and rear 3 wing of wing slightly string
Long identical, 15 ° of 5 angle of sweep of fixed fin, 0 ° of 5 camber angle of fixed fin.Primary control surface 4 is arranged in the middle part of forward and backward wing
Rear, primary control surface 4 can be used as aileron, can also be used as elevator, the 4 maximum degree of bias of primary control surface be -30 ° extremely+
30°。
