Description
Technical field
The utility model is related to unmanned air vehicle technique field, specially a kind of unmanned aircraft parachute descent device.
Background technology
Parachute is widely used in the recovery of unmanned plane, has the advantages that with parachute recovery unmanned plane simple to operate.Connect
To recovery command, from state of flight to safe landing, whole process is automatically performed aircraft.Operating personnel are required low.Additionally, drop
Falling, it is low to site requirements with receiving to take, and field condition is applied to without runway.So, many types use to lead and drop back to receive both at home and abroad.
And parachute as Emergency recovery means will also can be used using the unmanned plane of running landing.Some single uses nobody
Machine, without the collecting system that rises and falls, is often reclaimed in research ＆ development in flight experimental stage using parachute.For reusable unmanned plane,
In the development stage, special circumstances (such as engine is stopped work, aerial statue is out of control or the various system failures) are run into, should using landing
It is anxious to reclaim, air crash can be avoided, so as to accelerate Development Schedule, save research fund.
In unmanned plane performs task process, removal process is a stage easily broken down.There is data to show, nothing
The number of faults of man-machine removal process accounts for the 80% of the whole task failure number of unmanned plane.Will be as influence with this unmanned plane recovery technology
One of key issue of unmanned air vehicle technique development.In the prior art, the structure of unmanned aircraft parachute descent generally includes extractor parachute and main chute
Two parts are constituted, and volume is big, increase unmanned plane weight, and without entering to the angle of umbrella in descent for flight path
Row regulation, to effectively reduce parachute volume and obtain optimum recovery track, removal process is complicated.
Utility model content
In view of this, problem described in background technology is not solved, the utility model provides a kind of unmanned aircraft parachute descent device, can
Effectively reduce the volume and weight of parachute.
The technical solution of the utility model is：Unmanned aircraft parachute descent device, including parachute and umbrella storehouse, the parachute include
Umbrella body, is provided with hollow sandwich in the umbrella body, the umbrella body outer surface is provided with symmetrical two relief valves, umbrella body inner surface
Some through holes are provided with, the umbrella body is symmetrically connected with the first umbrella frame and the second umbrella frame, and first umbrella frame and the second umbrella frame are provided with
At least two mobilizable first Access Divisions, described first umbrella frame one end is connected by the first Access Division with the second umbrella frame；It is described
Umbrella storehouse includes base, is arranged on the accommodation space of chassis interior, the Cang Gai set with base engagement, the base and the Cang Gai
It is flexibly connected by rotating shaft, two the second Access Divisions, described second umbrella frame one end and the second card is symmetrically arranged with the rotating shaft
Socket part is connected.
Further, the umbrella body is folding structure, and several folded sections are provided with umbrella body, and the folded section can pass through
The adhesive portion for being arranged on umbrella body surface is folded.
Further, first Access Division has the snap ring of chute for surface, first umbrella frame and the second umbrella frame
Each section can be relatively moved by chute.
Further, the detent surface is provided with the snap ring of great friction coefficient.
Further, 1 the first Access Division is provided with first umbrella frame, 3 the first Access Divisions is provided with the second umbrella frame,
Described first umbrella frame one end is connected with first Access Division in the second umbrella frame stage casing.
In the utility model, each folded section of umbrella body is folded by adhesive portion, the accommodating sky in folding storage and umbrella storehouse
Between it is internal, umbrella Cang Canggai openings when unmanned plane land, parachute is formed because each folded section is folded by adhesive portion
Small umbrella body, serves as the role of extractor parachute, and when the air drag increase for receiving, each folded section struts and struts umbrella body completely to be formed
Main chute；And pass through the effect of umbrella body inner hollow interlayer, and air is filled during landing, increase the volume of umbrella body, increase
The resistance of decline, effectively slows down the speed of decline, while coordinating the effect of relief valve in umbrella body, it is to avoid because of the excessive damage umbrella of air-flow
Body；The first Access Division on first umbrella frame, the second umbrella frame can adjust the angle of umbrella body according to aircraft trace when declining, and can enter one
Step reduces flight path angular speed, last flight path is tended to plumbness, it is ensured that to obtain optimum recovery track, reaches overall drawdown parameter
To optimal, required with meeting to reclaim.
