Abstract
The present invention relates to a kind of ram air parachute parachute-opening control method, rotating parachute and annulus are set, when ram air parachute starts to spread out, rotating parachute is started working by windage, it is smaller that rotating parachute generation resistance and decrease speed get over slight drag, umbrella rope is gathered together by annulus, ram air parachute is slowly inflated, after ram air parachute is inflated to certain phase, ram air parachute decrease speed reduces, and rotating parachute rotary speed accordingly reduces, drop in resistance, the power of tightening of umbrella rope drives annulus slide downward, until the expansion of whole ram air parachute, rotating parachute failure.This method parachute-opening is reliable, and temporary impact overload is small, less demanding to the size of umbrella rope closing in band, implements simply, versatile.
Description
Technical field
The invention belongs to the field of dropping, and in particular to a kind of ram air parachute parachute-opening control method.
Background technology
Ram air parachute is a kind of new parachute, and it is divided into upper and lower two layers of sewing by micro- Air permenbility material
A kind of flexible flier of similar airfoil type, the initial state of ram air parachute is with flexible state FOLD AND PACK, with certain
In the case of speed, expansion inflation.
During ram air parachute is inflating expanded, due to the canopy of ram air parachute it is micro- ventilative the characteristics of, instantaneous gross area exhibition
Meeting brings greater impact power, and parachute-opening shock is higher than conventional parachute by more than 50%, and micro- used in general ram air parachute
The gas strength of materials is difficult to bear such parachute-opening shock power, causes canopy damaged, parafoil failure, so ram air parachute inflation need to be by
Level inflation, expansion, to reduce parachute-opening shock.
At present, ram air parachute parachute-opening control method is mainly controlled using the sliding cloth that closes up, but in actual applications, receive
The size of the sliding cloth of mouth and the matching relationship of aerofoil are difficult control, and the sliding cloth that closes up is too big, controls parafoil parachute-opening parachute-opening shock effect
Less, the sliding cloth that closes up can slide to umbrella rope end moment, and the sliding cloth that closes up is too small, may cause initial parachute-opening difficult again, instantaneous parachute-opening
Afterwards, parachute-opening shock can not effectively be controlled.Therefore, the matching of sliding cloth and the aerofoil size of closing up, it is necessary to many experiments are groped,
During applied to large-scale ram air parachute, it is clear that be unpractiaca.
The content of the invention
It is an object of the invention to provide a kind of ram air parachute parachute-opening control method, this method parachute-opening is reliable, temporary impact mistake
Carry it is small, it is less demanding to the size of umbrella rope closing in band, implement it is simple, it is versatile.
The technical solution adopted in the present invention is：
A kind of ram air parachute parachute-opening control method, the umbrella rope of ram air parachute is divided into symmetrical some beams, closed up in umbrella rope
Installation and the one-to-one annulus of umbrella rope beam are taken, umbrella rope beam is each passed through corresponding annulus, near two groups of symmetrical centre
Connect band is connected on annulus, all connect bands are compiled in the lower end of rotor, and the upper end of rotor is connected band connection with rotating parachute,
Rotating parachute connect band is connected through the aerofoil of ram air parachute with rotating parachute, and when ram air parachute starts to spread out, rotating parachute is by windage
Start working, rotating parachute produces resistance and decrease speed and gets over that slight drag is smaller, and umbrella rope is gathered together by annulus, and ram air parachute enters
Row slowly inflation, after ram air parachute is inflated to certain phase, ram air parachute decrease speed reduces, and rotating parachute rotary speed accordingly drops
Low, drop in resistance, the power of tightening of umbrella rope drives annulus slide downward, until the expansion of whole ram air parachute, rotating parachute failure.
Further, rotating parachute connect band passes the circular hole on the lower aerofoil and top airfoil of ram air parachute, lower aerofoil successively
With the circular hole on top airfoil point-blank.
The beneficial effects of the invention are as follows：
This method by ram air parachute whole air chamber when instantaneously all expansion are changed into expansion inflation it is slowly orderly
Inflation, improves the reliability of parachute-opening, delays the time that whole aerofoil chamber inflated is filled, and temporary impact is overloaded and reduced,
Meet canopy intensity requirement；This method provides resistance by rotating parachute and annulus, less demanding to the size of umbrella rope closing in band；Turn
Son causes rotating parachute not wind ram air parachute umbrella rope；This method implementation is fairly simple, only need to be compared with the rotating parachute of small area, so that it may
With meet different shape, size ram air parachute parachute-opening needs, it is versatile.
Brief description of the drawings
Fig. 1 is schematic diagram when ram air parachute has not yet fully deployed in the embodiment of the present invention.
Fig. 2 is schematic diagram when ram air parachute is fully deployed in the embodiment of the present invention.
In figure：1- umbrella rope closing in bands；2- connect bands；3- rotors；4- ram air parachutes；5- rotating parachute connect bands；6- rotating parachutes.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
A kind of ram air parachute parachute-opening control method, as shown in figure 1, the umbrella rope of ram air parachute 4 is divided into symmetrical some beams,
Installation and the one-to-one annulus of umbrella rope beam on umbrella rope closing in band 1, umbrella rope beam is each passed through corresponding annulus, near symmetrical
Connect band 2 is connected on two groups of annulus at center, all connect bands 2 are compiled in the lower end of rotor 3, the upper end of rotor 3 and rotation
Turn umbrella connect band 5 to connect, rotating parachute connect band 5 is connected through the aerofoil of ram air parachute 4 with rotating parachute 6, and ram air parachute 4 starts to open up
When opening, rotating parachute 6 is started working by windage, and rotating parachute 6 produces resistance and decrease speed and gets over that slight drag is smaller, and umbrella rope is by annulus
Gathering together, ram air parachute 4 is slowly inflated, after ram air parachute 4 is inflated to certain phase, the decrease speed of ram air parachute 4
Reduce, the rotary speed of rotating parachute 6 accordingly reduces, drop in resistance, and the power of tightening of umbrella rope drives annulus slide downward, until whole punching
Parafoil 4 deploys pressure, rotating parachute 6 fails.
In the present embodiment, rotating parachute connect band 5 passes the circular hole on the lower aerofoil and top airfoil of ram air parachute 4 successively,
Circular hole on lower aerofoil and top airfoil is point-blank.
This method by 4 whole air chambers of ram air parachute when instantaneously all expansion are changed into expansion inflation it is slowly orderly
Inflation, improves the reliability of parachute-opening, delays the time that whole aerofoil chamber inflated is filled, and temporary impact is overloaded and reduced,
Meet canopy intensity requirement；This method provides resistance by rotating parachute 6 and annulus, less demanding to the size of umbrella rope closing in band 1；
Rotor causes rotating parachute 6 not wind the umbrella rope of ram air parachute 4；This method implementation is fairly simple, only need to be compared with the rotating parachute of small area
6, it is possible to meet different shape, size the parachute-opening of ram air parachute 4 needs, it is versatile.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
