[specific embodiment]
The invention will be further described below in conjunction with accompanying drawing, the present invention concerning those skilled in the art still clearly.
Referring to accompanying drawing 1, a kind of safety self-saving device that can on helicopter, install, specifically comprise: one, aircraft rotor main driving axle unit, comprise main driving axle 1, guide pipe 2, center bearing pilot bearing 3, wherein, main driving axle 1 is a hollow cylinder, includes guide pipe 2, the two is a concentric, and the gap between main driving axle 1 and the guide pipe 2 is provided with center bearing pilot bearing 3.
Two, the main gear unit, comprise main gear 4, spin landing group 9, unilateral bearing lining 10, unilateral bearing 11, main gear lining 12, be also referred to as main gear individual event gear, unilateral bearing liner 13 and screw, unilateral bearing lining 10 concentrics are enclosed within on the main driving axle 1, and it is fixing with screw 14, unilateral bearing 11 is nested on the unilateral bearing lining 10, be supported on unilateral bearing 11 lower ends with unilateral bearing liner 13, then main gear lining 12 is enclosed within on the unilateral bearing 11, the main gear lining is a projection in the middle of 12 outsides, form two parts up and down, the first half overcoat main gear 4, the latter half is overcoat spin landing group 9 then, the radical function of spin landing group 9 is when helicopter aloft flies, driving engine breaks down and runs out of steam or when flame-out suddenly, utilize helicopter own wt and acceleration due to gravity principle, with change lifting airscrew pitch, promptly strengthen negative pitch, helicopter is when descending fast, main rotor can be rotated automatically, and remain on the flight attitude that certain speed is controlled helicopter, it can farthest be reduced the loss.
Three, main oar folder unit comprises main oar folder 6 and middle 5, and main oar folder 6 and middle 5 is nested in the outer tops of main driving axle 1, and main oar folder 6 is used to connect the main rotor of aircraft.
Four, umbrella warehouse receipt unit, comprise umbrella storehouse 8 and umbrella storehouse permanent seat 7, wherein, establish groove in the middle of 8 outer bottoms of umbrella storehouse, the disk position of permanent seat 7 upper ends, umbrella storehouse embeds in this groove, the cylinder type sleeve pipe concentric of permanent seat 7 lower ends, umbrella storehouse is enclosed within the top of guide pipe 2, makes umbrella storehouse 8 be fixed in guide pipe 2 tops, adopts screw 15 that umbrella storehouse permanent seat 7 is captiveed joint with guide pipe 2.
The main shaft of guide pipe in the safety self-saving device for vertically taking off and landing flyer 2 with the vertically taking off and landing flyer top linked to each other, when aircraft is worked, the driving engine of aircraft reaches main gear 4 with kinetic energy, main gear 4 is rotated, main gear 4 then drives main driving axle 1 and rotates, at this moment, and along with the raising of engine speed, make bonded assembly aircraft main rotor high speed revolution and change pitch obtain lift by main oar folder 6, make aircraft takeoff and flight.
Umbrella storehouse 8 is positioned at guide pipe 2 tops, when the aircraft normal flight, can not influence the normal flight of aircraft, when emergency appears in aircraft, at first the power transmission with driving engine breaks away from by spin landing group 9 and main driving axle 1, aircraft rotor is because of running out of steam like this, with the former rotatory inertia speed that slows down gradually, when aircraft runs out of steam when down falling, the parachute that is positioned at umbrella storehouse, guide pipe 2 top 8 ejects automatically and opens by difference beat control system, and aircraft is slowly landed, and has both guaranteed the safety of aircraft, guarantee the safety of ground staff and property again, made loss reduce to minimum.Wherein difference beat control system is used for the ejection of parachute and opens, and can be installed near the helicopter center of gravity, and most cases is at the close main shaft place of fuselage side plate.
Referring to accompanying drawing 3a-c, after being sent to the umbrella storehouse lid steering wheel 22 that is positioned at umbrella storehouse 8 when signal, by difference beat control system, make steering wheel rocking arm 23 horizontally rotate the 90-120 degree left, the hook 6 of umbrella Cang Gai is thrown off with it, under the tension of umbrella Cang Gai because of rubber band 29 umbrella Cang Gai is opened, have hinge 9 to link to each other between umbrella Cang Gai and the umbrella storehouse, can rotate along the hinge axle umbrella Cang Gai is opened.
Referring to accompanying drawing 4a-b, the introductory note pilot chute 31 that thereupon is positioned at umbrella storehouse 8 is at first dished out from umbrella storehouse 3 under the application force of air and is opened, pilot-parachute drives the main parachute 32 that is positioned at umbrella storehouse 21 again and also ejects umbrella storehouse 8 and open, aircraft has slowed down the speed that descends under the effect of main parachute 32 lift like this, thereby reached the purpose of safe falling, guarantee the safety of aircraft, reduced loss.
