Description

The parachute assembly of helicopter

A kind of parachute assembly that provides safety to delay the helicopter of the effect of falling is provided the utility model.

General helicopter does not have the slow equipment that falls of any safety; just in case under the emergencies such as forfeiture power that helicopter is unexpected awing or et out of order; the high helicopter of cost just crashes at this point; not only cause monetary loss; the more important thing is; to driver's life be constituted a serious threat; especially in airplane crash frequent today of taking place; make especially general masses have safety on doubt; therefore how to provide the driver in the safety guard-safeguard effect of taking advantage of when driving, become the important goal that relevant dealer actively researches and develops, improves.

It is a kind of when meeting with emergency situation that the purpose of this utility model is to provide, and can reach the parachute assembly of the slow helicopter that falls of safety.

The parachute assembly of the utility model helicopter includes an axostylus axostyle, one container, one pack, one rope, one rocket socket and a control lead-in wire, this axostylus axostyle is the hollow tube shape, and axle is located at the rotor axle drive shaft inside of helicopter, this axostylus axostyle inside is provided with a saturating up and down empty through hole, its bottom is fixed in the pre-position of helicopter body, this container is to be socketed into the box body that inside is hollow by a loam cake and a bottom, this bottom is fixedly arranged on this axostylus axostyle top, this parachute pack is located in this container, its inside contains a parachute, and this pack utilizes a ripcord and this loam cake to be connected, this suspension cable one end placed the through hole of this axostylus axostyle and was fixedly arranged on appropriate position in the helicopter, the other end then is connected with the umbrella rope of this parachute, this rocket socket is installed in this container one side, its stack shell inside is provided with a rocket body to link a connecting strand, this connecting strand one end and this loam cake link, the fire in a stove before fuel is added of this control lead-in wire one end and rocket socket is affixed, after the other end then placed this through hole, and involve to operator's saddle one side.

Whereby, when emergency situation takes place, can spur that this control goes between and after making the rocket socket explosion, the rocket body is upwards gone out and is utilized connecting strand that this loam cake is lifted on bottom and open disengaging, and one pulls out this pack, forces this parachute to expose and supports, and helicopter can reach urgent slow purpose of falling.

Be elaborated below by most preferred embodiment and accompanying drawing parachute assembly to helicopter of the present utility model, in the accompanying drawing:

Fig. 1 is the local appearance figure of the utility model first preferred embodiment.

Fig. 2 is the parachute assembly schematic internal view of the above-mentioned preferred embodiment of the utility model.

Fig. 3 is the partial perspective view of the above-mentioned preferred embodiment of the utility model.

Fig. 4 is the running condition scheme drawing of the above-mentioned preferred embodiment of the utility model.

As shown in Figure 1 and Figure 2, the parachute assembly of the utility model embodiment helicopter is installed on the helicopter, and the intrinsic gear case 70 of these helicopter 100 internal locks, can be by an engine 80 imput powers, export rotary torques and drive a rotor axle drive shaft 90, and these gear case 70 belows have a fixed part 71, this rotor axle drive shaft 90 is hollow form, can be for a parachute assembly to be installed, this kind parachute assembly consists predominantly of an axostylus axostyle 10, a container 20, a pack 30, a suspension cable 40, a rocket socket 50 and a control lead-in wire 60.

This axostylus axostyle 10 roughly is the hollow tube shape, be arranged on this rotor axle drive shaft 90 inside, these axostylus axostyle 10 inside are provided with a saturating up and down empty through hole 11, and a chassis face 72 of borrowing its bottom is locked in the fixed part 71 of gear case 70, then be provided with a lining 13 and a bearing 14 between epimere and this rotor axle drive shaft 90, make this rotor axle drive shaft 90 form the cover pivot, and this axostylus axostyle 10 is done turn relatively in these axostylus axostyle 10 peripheries.

This container 20 is to be socketed into the box body that inside is hollow by a loam cake 21 and a bottom 22, this bottom 22 is locked in saturating empty pedestal 23 tops, the end, a top, this pedestal 23 is to utilize a key 231 and a nut 232 to be fixed in this axostylus axostyle 10 tops, frame stands on rotor axle drive shaft 90 tops to make container 20 form firmly, and is not subjected to rotor axle drive shaft 90 rotation and rotates.

This pack 30 is furled a parachute 31 folding in advance and coats behind the umbrella rope and constitute, and can utilize fine rule to wear in advance to walk around pack 30 and fix slightly, it can be accommodated in this container 20, and this pack 30 is to utilize a ripcord 32 to be connected with this loam cake 21.

This suspension cable 40 is made the closed-loop round and was placed the through hole 11 of this axostylus axostyle 10, please cooperate consult shown in Figure 3, the one end is crossed an anchor pole 73 that is fixed in gear case 70 bottoms around the home, and suspension cable 40 other ends then borrow a ring 42 and the umbrella rope 311 of this parachute 31 to be connected.

This rocket socket 50 is installed in bottom 22 1 sides of this container 20, and its stack shell 51 inside are equiped with a rocket body (figure does not show) to link a connecting strand 52, and the ripcord 32 of these connecting strand 52 1 ends and this loam cake 21 and parachute 31 links.

The fire in a stove before fuel is added of these control lead-in wire 60 1 ends and rocket socket 50 is affixed, after the other end then placed the through hole 11 of this axostylus axostyle 10, and involves to helicopter 100 operator's saddles one side, can be subjected to a handle 61 pull lift action.

The parachute assembly of forming by above-mentioned member, when situations such as in a single day unexpected forfeiture flying power of helicopter 100 or et out of order, see also Fig. 1, shown in Figure 2, at this moment, driver in helicopter 100 driving compartments just can draw and pull at the other handle 61 of operator's saddle, go between 60 and lift this control, make this rocket socket 50 stack shells 51 inner gunpowder explosions, can involve connecting strand 52 when the rocket body is upwards gone out and raise loam cake 21, simultaneously ripcord 32 is up torn, ripcord 32 will be pullled pack 30 (fine rule that was used for fixing pack 30 originally can be pulled apart in moment), and finish the action of parachute-opening, and force these pack 30 interior parachutes 31 to expose apace and support, as shown in Figure 3, this suspension cable 40 is pulled tightly by the weight of helicopter 100, because suspension cable 40 1 ends are around the home in gear case 70 bottoms, and gear case 70 locks in helicopter 100 bodies, and so, helicopter 100 just can utilize this parachute 31 and reach slow effect of falling.

So, the parachute assembly that the utility model utilization is installed above helicopter 100 can just can be opened this parachute 31 driver in the fastest time, to provide slow behind the helicopter 100 forfeiture flying powers to fall effect, so as to ensureing driver's flight safety.
