Difficulty and reduce the reliability of parachute-opening；Umbrella rope, which is easily wrapped in, to be led to not smoothly pop up on rubber band；Rubber band is formed
Ejection wire side cavity greatly, pack easily leaks through rubber band net and can not pop up.The hatchcover and cabin of the utility model rocket are cut with scissors
It connecing, does not separate, hatchcover laterally flicks after trigger device is triggered, and hatchcover and cabin are completed to land by a parachute,
Script Separation is solved as two parts, the coiling for needing to be generated using two parachutes, two parts overlapping are hit
The problem of.The utility model is got rid of in the prior art by preset height or time trigger parachute-opening bring unreliability, and
Pack and elastic device are respectively arranged in the inside and outside of cabin, the drawstring and elastic device for thoroughly having prevented pack are wound
The case where causing parachute-opening to fail.Should be simple from triggering hydrodynamic force rocket structure, implement reliably, it is cheap, it is suitable for aviation mould
The application of type technical field.Landing pack is placed on bracket, by the principle of sling parabolic in hatchcover by the utility model
Laterally while flick, dish out by the inertia of the hatchcover pop-up pack that will land, avoid landing pack contacted with elasticated net and
The problem of coiling occurs, greatly enhances the reliability of parachute-opening.
