Description
Technical field
The present invention relates to unmanned plane fields, more particularly to unmanned plane folding field.
Background technique
In Development of UAV rapid today, application mode has penetrated into every field.Transport about unmanned plane
It carries, the use of the overall performance of deployment, flight be always the principal element that designer considers.It is wherein readily transported carrying and makes
It relates to fold and unfold technology to unmanned plane with deployment, it is desirable that lesser space can be stored in, as far as possible in order to carry fortune
It is defeated；The unmanned plane cruising ability of miniaturization handling is intended to reach good index.
:
1 folding problem about unmanned plane: to allow unmanned plane transport easy to carry, deployment, aircraft must must be folded.It is existing
In the conventional folding mode used based on fuselage, wing is rotated around fuselage, and which subtracts there are wing power transmission effect is poor
The problems such as weak intensity and rigidity of wing, foldable structure is heavy.
The overall performance problem of 2 aircrafts: conventional folding mode causes folding system weight to increase, and the rigidity of wing subtracts
It is weak, it is only applicable to low aspect ratio unmanned plane, causes collapsible unmanned plane cruising ability poor.
Summary of the invention
To solve the conventional folding mode bring above problem, folded the present invention provides a kind of by L-type connector
System can make the automatic rapid deployment of aircraft, be laid out after expansion in middle font, and the front and back wing and main wing tandem ladder are distributed, and have
Effect reduces interfering with each other between three wings, has reached pneumatic optimum optimization.
L-type fold in font be laid out unmanned plane, including front wing L-type folded piece, front wing, fold lock system, main wing, rear wing,
Rear wing L-type folded piece and dynamical system, front wing are connect by front wing L-type folded piece with main wing, and rear wing passes through rear wing L-type folded piece
It is connect with main wing, dynamical system is propeller set, and in terms of tail direction, propeller clockwise is arranged in the middle part of main wing.
Further, the front wing of font layout unmanned plane and rear wing and main wing are the distribution of tandem ladder in L-type folding.
Further, the fold latch internal system of font layout unmanned plane is provided with automatic control system in L-type folding, from
Autocontrol system is associated with the flight control system of aircraft to stretch or shrinks automatically front wing and rear wing according to required state.
The advantageous effects obtained by the above-mentioned technological means present invention are as follows: font is laid out unmanned plane in L-type folding
Unique innovation, it is simple and reliable.Automatic-expanding system and the flight control system of aircraft are associated, and while aircraft is unfolded, it is steady to fly control increasing
Mode starting, guarantees attitude stabilization when aircraft just takes off.The forward and backward wing and main wing are distributed using tandem ladder, are effectively reduced
Interfering with each other between three wings, has reached pneumatic optimum optimization, effectively raises the lift resistance ratio of aircraft；After expansion
Aircraft is laid out in middle font, is a kind of completely new layout type.
Detailed description of the invention
Explanatory diagram of the invention is as follows:
Fig. 1 is expanded schematic diagram of the invention；
Fig. 2 is folding process schematic diagram of the invention；
Fig. 3 is schematic diagram after folding of the invention；
In figure: 1, front wing L-type folded piece；2, front wing；3, lock system is folded；4, main wing；5, rear wing；6, rear wing L-type folds

Specific embodiment
Description of specific embodiments of the present invention with reference to the accompanying drawing:
L-type fold in font be laid out unmanned plane, including front wing L-type folded piece 1, front wing 2, fold lock system 3, main wing 4, after
The wing 5, rear wing L-type folded piece 6 and dynamical system 7, front wing L-type folded piece 1 is connect by L-type part 1 with main wing 4, after rear wing 5 passes through
Wing L-type folded piece 6 is connect with main wing 4, then does rotary folding counterclockwise (see Fig. 2) respectively around owner's wing, and dynamical system 7 is suitable
Clock rotation, vertical fin are folded inward, and unmanned plane can be folded into a cuboid (see Fig. 3).Fold mechanism passes through the inside
Lock system 3 is folded, can be automatically opened.Automatic-expanding system and the flight control system of aircraft are associated, while aircraft is unfolded, fly
Control increases steady mode starting, guarantees attitude stabilization when aircraft just takes off.
Aircraft layout of the invention: aircraft is laid out in middle font, and the front and back wing and main wing tandem ladder are distributed, and is effectively reduced
Interfering with each other between three wings, has reached pneumatic optimum optimization, effectively raises the lift resistance ratio of aircraft (see figure
1)。
Aircraft before take off, is powered to aircraft, and the flight control system of Automatic-expanding system and aircraft is associated, aircraft expansion
While, fly control and increase steady mode starting, guarantees attitude stabilization when aircraft just takes off.Pilot fight has been completed in the invention, card
Bright flight theory is feasible.
The folding unmanned plane, which overcomes, mainly to carry out wing in conventional airplane folding to fold bring load path
It interrupts, the problem that strength/rigidity weakens, using unconventional folding mode, i.e., the forward and backward wing passes through L-type rotary connector and main wing
Connection, rotary folding counterclockwise, main wing is without folding.Vertical fin is folded inward by torsional spring hinge, in length after unmanned plane folding
Rectangular box-like form can be laid out after expansion in middle font with Automatic-expanding, and the front and back wing and main wing tandem ladder are distributed, effectively
Interfering with each other between three wings is reduced, pneumatic optimum optimization has been reached, improves the cruise performance of aircraft.This nobody
Machine can be used for individual take photo by plane, scientific investigation, rescue and relief work etc..
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
