Description
Technical field
The present invention relates to equipment drop from the air safety protection field, and in particular to it is a kind of equipment drop from the air multi-stage gasbag collaboration buffering dress
The working method set.
Background technology
Air bag buffer has been widely used for equipping airborne, unmanned plane time because of the features such as light-weight, energy-absorbing effect is good
The technical fields such as receipts, space flight return, and as the important component of equipment safety guarantee.
In actual equipment drops from the air landing mission, the buffering effect of existing air bag buffer is limited, and there are following
Problem.
In existing airborne equipment landing air bag buffer, most of single gasbag buffering dress single using structure
It sets, to cause the setting of gas chamber initial buffer air pressure excessively single and there are limitations, causes buffering effect limited.
Existing list gasbag buffer unit is vented outward by gas vent, to realize pressure release.But it is airborne in equipment
During landing buffer, if air bag buffer gas vent is excessive, there are problems that airborne equipment directly contacts to earth；If gas
Capsule buffer unit gas vent is too small, is easy to increase severely because of airbag chamber internal pressure and exhaust velocity causes air bag quick-fried slowly excessively outward
Broken, this will bring fatefulue damage to airborne equipment.
The shortcomings that in order to overcome the easy explosion of single gasbag buffer unit, the small part prior art has used double gasbag
The technical solution of buffer unit：Such as the patent " multi-stage gasbag combination buffer unit " of Publication No. CN1923617A, but it is this more
Grade gasbag combination buffer unit is limited so as to cause effective cushion stroke using nested structure；Such as Publication No.
The patent " double gasbag buffer unit " of CN1923618A, although to use air bag top air chamber gentle for this air bag buffer
The mounting means of capsule spirit room superposition, but still caused without other buffer units between air bag top air chamber and air bag spirit room
Imitate that cushion stroke is limited, and air bag top air chamber and air bag spirit room are two sseparated independent air chambers, cause two gas chambers without
Method carries out collaboration buffering to airborne equipment, therefore cannot play good buffering effect to airborne equipment.
