Description
Technical field
The present invention relates to parachute technology fields, control more particularly to a kind of unmanned plane parachute and unmanned plane parachute
System.
Background technique
UAV is to utilize radio remote-controlled telemetry equipment and the presetting apparatus provided for oneself referred to as " unmanned plane "
The not manned aircraft of manipulation, without cockpit on machine, but be equipped with navigation and flight control, presetting apparatus and power and
The equipment such as power supply, ground remote control telemetry station personnel track it, are positioned, are remotely controlled, telemetering sum number by equipment such as data-links
Word transmission has the characteristics that small in size, low cost, easy to use, a variety of flight environment of vehicle requirements of adaptation compared with manned aircraft,
Can be widely used in air remote sensing, meteorological research, agriculture plant seeds by airplane and the prevention and control of plant diseases, pest control and the aerial reconnaissance in war, monitoring,
Communication, antisubmarine, electronic interferences etc., therefore, the universal range of unmanned plane industry increase, and the growth of unmanned plane quantity is also very fast.
Falling in unmanned plane use process is easy to injure by a crashing object the mankind and damage building etc., especially technical grade nobody
The utilization of machine, occur air crash and caused by personnel and property safety problem, bring economic loss is far super with unmanned plane itself
Value, such safety problem have become global technical problem, therefore complete in some public situations or special area
Face is forbidden to use unmanned plane, therefore gradually perfect for unmanned plane relevant regulations, and the safety problem in unmanned plane use process is
Become important problem.
Existing majority unmanned plane does not have the safety guard of any active, not for the unmanned plane that accident occurs
Precautionary measures and safeguard measure, some unmanned planes avoid security risk when unmanned plane air crash using parachute, wherein Shen
Number it please disclose a kind of fixed-wing unmanned plane parachute for 201710752695.2 a Chinese patent and discharge system, comprising: can
It is connected to the attachment device of unmanned plane and parachute, and can be controlled discharge from unmanned plane by servo actuator and connect member
The locking structure of part；Parachute discharges structure by parachute and is fixed on fixed-wing unmanned plane；Parachute release device is fixed
On fixed-wing unmanned plane, this patent fixes unmanned plane parachute and discharges operability with higher, in special circumstances
Under (such as unmanned plane hang on branch or unmanned plane landing after parachute situations such as blowing afloat again), it is necessary to quickly judge whether
" key " discharges parachute, protects unmanned aerial vehicle body, and parachute is repeatable to be recycled, and can protect unmanned aerial vehicle body and machine in time
Expensive equipment in cabin, but its there are intelligence degrees low, problem that parachute-opening effect is poor, complicated for operation.Other existing landing
The structure of umbrella generally has spring parachute-opening and compressed gas injecting type parachute-opening two ways, both parachute-opening modes, which also all exist, to be opened
The problem that umbrella effect is unreliable, high failure rate, recycling rate of waterused are low.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of unmanned plane parachute, parachute of the invention exists
Have the advantages that parachute-opening is reliable while reducing the weight of parachute, can be used repeatedly；Another object of the present invention
It is to provide a kind of unmanned plane parachute control system, the control system intelligence degree is high, it can be achieved that automatic deployment, automatic report
Police, location tracking, security protection function, while improving the reliability of unmanned plane state of emergency parachute-opening and unmanned plane is opened
The convenience of unmanned plane position is found after umbrella landing.
Based on this, the present invention provides a kind of unmanned plane parachute, the umbrella including mounting base, umbrella body and upper opening
Bucket, the umbrella bucket are fixed at mounting base top to form the placement space for placing umbrella body, in the placement space
It is provided with the catapult-launching gear for umbrella body to be ejected to umbrella bucket, the catapult-launching gear includes the fire being fixed on mounting base
The top of powder flask is arranged in explosive barrel, umbrella body, is disposed with gunpowder and the electric arc hair for lighting gunpowder in powder flask up and down
Raw device, the arc generator are connected with controller, generate arc ignition gunpowder to control the arc generator, fire gunpowder
It burns and generates gas to pop up umbrella body.
On the one hand setting powder flask and gunpowder are used for parachute-opening to unmanned plane parachute of the invention, are less than 1.5g using weight
Solid-state gunpowder, by arc generator generate arc ignition gunpowder, powder burning generate gas push umbrella body opening, with
The spring parachute-opening of unmanned plane parachute in the prior art is compared with compressed gas injecting type parachute-opening mode, solves existing skill
Parachute-opening mode in art has the technical problem that structure is complicated, components are more, overall weight is big, and solves because of parachute weight
The problem of continuation of the journey of unmanned plane caused by amount increases reduces, the present invention have that parachute overall weight is low, structure is simple, not rapid wear
Bad advantage；Another rigid face, the power due to the gas using powder burning generation as parachute-opening, solid-state gunpowder is by arc ignition
Burning time is energized to less than 0.2s, solid-state gunpowder moment generates a large amount of gas, forms powerful air burst power, make gas
Speed with higher and power can quickly pop up umbrella body, solve traditional parachute because ejection force deficiency and ejection open
The dynamic time is long and umbrella body pops up the problem of failing, and especially in relatively large unmanned plane because of parachute umbrella body weight itself, causes to play umbrella
Hypodynamic problem keeps parachute-opening of the invention reliable；In addition, parachute of the invention can be used repeatedly, in parachute one
After secondary use, takes out powder flask and reload solid-state gunpowder in powder flask, gunpowder is easy to carry, and parachute being capable of fast and easy
Replacement gunpowder when needed, parachute can be put into after test passes, reuses parachute, whole process operation
And its it is simple, achievable operation outdoors keeps the recycling effect of parachute of the invention reliable, solves in the prior art
Parachute assembly reuses the problem that process is complicated, utilization efficiency is low, such as the compression carbon dioxide used in the prior art
The parachute of gas pop-up, reuse when, need air-pressure equipment to carry out inflating gas cylinder, and the program of reuse is complicated, and empty
Press equipment not readily portable, parachute utilization rate is low.
