Description
Technical field
The invention belongs to parachute technology field, more particularly to a kind of fixed-wing unmanned plane parachute release system.
Background technology
One of method of unmanned plane landing is exactly to use parachute.After unmanned plane umbrella storehouse is opened, parachute is by gravity
Act on and decline with unmanned plane tractive force, during decline, parachute system also has by causing relative to the wind drift on ground
Horizontal velocity.Current existing parachute is all integrally fixed on unmanned aerial vehicle body, when be suspended on below parachute nobody
When machine reaches ground, strong wind may inflate parachute, and produce enough strength and arrive fixed-wing unmanned plane (UAV)
Place pulls, or because some accidentalia cause unmanned plane to be suspended on some objects (such as branch, cliff road), causes pair
UAV infringement.If the fuselage and wing of unmanned plane reach ground in non-horizontal position, may be to UAV other frames
Part causes further to damage, so as to prevent after aircraft landing in the case of accidentally from above-mentioned infringement, therefore, this area
Need to develop a kind of horizontal landing for allowing unmanned plane and effective and reliable parachute release structure.
In summary, the problem of prior art is present be：At present because parachute is integrally fixed on unmanned aerial vehicle body, drop
Fixed-wing unmanned plane is influenceed by wind, topography and geomorphology etc. when falling, and unmanned plane easily pulls everywhere, or due to some accidentalia
Cause unmanned plane to be suspended on some objects, cause the infringement to UAV.
The content of the invention
The problem of existing for prior art, the present invention are achieved in that a kind of fixed-wing unmanned plane parachute release
System, the fixed-wing unmanned plane parachute release system include：
(1) triangular connecting element of the unmanned plane (UAV) between parachute can be connected；One kind can actuating when from
The UAV discharges the latch-up structure of the triangular connecting element；
(2) wherein described triangular connecting element lower surface has locking angle (acute angle), to lock unmanned aerial vehicle body；
Also include servo actuator and latch-up structure, it can pull connecting rod to be connected to release arm by rotary motion；Parachute passes through
Three line is connected to connecting element delta-shaped members.Servo and latch-up structure can be fixed on fuselage.
Further, umbrella cabin is provided with below the fixed-wing unmanned plane, when parachute struts, parachute can be to nobody
Machine applies powerful reaction force.According to some case study on implementation, parachute release device can be designed as withstanding this height
Impulsive force is without damaging device and not being torn from aircraft.
Further, parachute release device is immersed in unmanned plane (UAV) framework, therefore has low profile, so can be with
Reduce UAV aerodynamic drag.
Further, the parachute release structure includes the connecting element for being connectable to unmanned plane and parachute, and
Can be controlled by servo actuator can discharge the latch-up structure of connecting element from unmanned plane.Servo is pulled by rotary motion to be connected
Bar is connected to release arm；The arm of bearing on release arm moves forward and discharges triangular connecting element by lock arm；
Further, connecting element is assemblied in the recessed unmanned plane cavity on aircraft surface.Servo and latch-up structure
The fuselage of unmanned plane is connected to by element.Parachute is connected to connecting element by cable；Connecting element passes through at least three
Cable is connected to parachute, and three cables may be coupled to single line cable, and wherein single line cable is connected to parachute.Wherein connect
Point can be on the center of body nodal point point, because tie point is higher than the focus point of fuselage, so aircraft declines in parachute
Period may keep level.
Connecting element can be included in the linking arm that delta-shaped members are locked when being in the locked position, and work as servo actuation
When device drives, the linking arm can discharge delta-shaped members from latch-up structure.
Further, the angle between the delta-shaped members lower surface and rear side is acute angle, is on rear side of delta-shaped members
The triangle edges farther apart from linking arm.During parachute struts, longitudinal force effect can be recessed in unmanned plane by connecting element
Locked in groove.
Further, the parachute release device includes servo, and link connection to release arm is with its upper bearing (metal), being configured to
The connecting element and lock arm of triangle；When latch-up structure is in the locked position, connecting element is in a fixed position；Work as locking
When structure is in an open position, connecting element is in non-fixed position；IR (infrared), RF (radio frequency), servo command can be passed through
Deng activation actuator release connecting element.Parachute is connected to the equipment by three cables；Servo and latch-up structure can be direct
It is fixed on fuselage.
Further, after unmanned plane reaches ground, the power acted on the parachute of expansion can pull in any direction
Line, and delta-shaped members are released.
Advantages of the present invention and good effect are：The present invention, which is fixed and discharged for unmanned plane parachute, has higher behaviour
The property made, under special circumstances (parachute is blown afloat again after such as unmanned plane is hung on branch or unmanned plane lands), it is necessary to
Quickly judge whether that " key " discharges parachute, unmanned aerial vehicle body can be protected, extend unmanned plane service life.Parachute of the present invention
It is repeatable to recycle, parachute fixed releasing device convenience quick for installation, release device can by being remotely controlled a key remote operation,
The time of manual teardown parachute is substantially reduced, expensive equipment in unmanned aerial vehicle body and cabin can be protected very much in time.
