Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment：As shown in figures 1 to 6, a kind of technical solution of present invention offer, a kind of unmanned plane that fail-safe is crashed, including
Unmanned plane 1, standby flatulence capsule 2 and parachute 3 are provided on the unmanned plane 1, and unmanned plane 1 increases the resistance of its air in dropping process
Power is provided with parachute compartment 4 at the top of the unmanned plane 1, and the parachute compartment 4 includes umbrella hatchcover 25 and servo 19, institute
The opening forward position that servo 19 is mounted on the umbrella hatchcover 25 is stated, 25 upper end of umbrella hatchcover is equipped with self-adhesive fixed seat 20, institute
It states umbrella hatchcover 25 and vertical tail 23 is connected with by hinge 24, the vertical tail 23 is all provided with in the self-adhesive fixed seat 20
There is through-hole, and a rubber band 21, institute are wrapped with by the through-hole between the vertical tail 23 and the self-adhesive fixed seat 20
A diameter of 2-4mm of rubber band 21 is stated, core number is 42-60, and aluminium collet 22 is equipped between 21 both ends of the rubber band and the through-hole,
The servo 19 is equipped with servo rocking arm 26, and the parachute compartment 4 is built-in with the parachute 3 of contraction, in the unmanned plane 1
The both sides of abdomen are symmetrically arranged with standby flatulence capsule 2, and from air compressor machine 5, air accumulator 6 and inflation solenoid valve 7 to two for flatulence capsules 2
The hatch door 14 of inflation, the parachute compartment 4 controls 8 by dead electricity trigger switch, and the dead electricity trigger switch 8 is by electromagnet 16 and iron
