Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helicopter having a drift plate, a shaping member and the like on its body and a protection device on its hoist rope.

[0002]

2. Description of the Related Art A conventional helicopter does not have the deflector plates 10 and 19 or the shaping members 36 and 41 as in the present invention, and a circulating flow 64 as shown in FIG. 20 is generated between the helicopter and the ground. Was. Therefore, there is a problem that the helicopter engine sucks in solid foreign matter such as sand and pebbles. In order to prevent such solid foreign matter from being sucked in, there is a helicopter equipped with a dust separator 58 as shown in FIG. 19 in front of the engine.

Further, in a conventional helicopter, as shown in FIG. 18, a hoist 38 is attached to a hoist column 37 on the body of the helicopter 1, and a rope 39 is attached to the hoist 38. By operating the hoist 38, the rope 39 is lowered,
The person 40 to be rescued by being wound up was rescued from the ground or the sea via the life preserver 48. Conventionally, the protection device 33 as in the present invention has not been attached.

[0004]

[Problems to be Solved by the Invention]

(1) When the helicopter is hovering near the ground (flying in the air), a circulation flow 64 is generated between the helicopter and the ground as shown in FIG. Therefore, solid foreign matter such as sand and pebbles on the ground may be sprinkled, which may be sucked into the engine 4 to damage the engine or cause a trouble (trouble) in the engine 4, leading to a helicopter accident. .

In order to prevent solid foreign matter such as sand and pebbles on the ground from being sucked into the engine 4,
It is necessary to specially attach the dust separator 58 as shown in FIG. However, these need to be purchased and prepared as an option, and extra cost is required.

Further, when the high temperature exhaust gas discharged from the engine becomes the circulation flow 64 and is again sucked as high temperature air from the inlet of the engine, the output of the engine is deteriorated and the hovering performance of the helicopter is deteriorated. become. (2) When the helicopter is flying near the sea surface and is hovering, as shown in FIG. 21, the downslide 21 by the main rotor 2 of the helicopter collides with the sea surface and winds the spray to blow seawater to the body. There are also problems such as bumping and accelerating the corrosion, and degrading the visibility of the pilot 15 due to water splashing on the glass in the front of the cockpit. (3) When using a hoist 37 to pull a rescued person on the ground or at the sea surface to a helicopter, conventionally, FIG.
The hoist attached to the body as shown in FIG. 6 lowers the rope, and the rescuer 40 (having a ring shape) attached to the tip of the rope rescues the person 40.
The body is placed on the life-saving tool 48, and the hoist 38 is wound up by the operation of the crew member 55 of the helicopter 1 to be hoisted and rescued by the helicopter 1.

However, while the helicopter is hovering, the rope, the life preserver, and the rescued person are shaken by the intense downwind generated by the rotation of the main rotor 2 of the helicopter, and in the worst case, the lower portion of the rope and the body. There is a possibility that the torso may come into contact with the torso and the torso may be severely cut, and the rescue work may not be successful or may be in a dangerous state.

In addition, the rescuer who is caught in the life preserver is the downwinder 21 generated by the main rotor 2 of the helicopter.
Since it is located in the center of the
Exposed to the strong wind.

Since the person 40 to be rescued has weak physical strength, it is difficult to endure the descent. Further, even for a person who is working on the ground or at the sea below where the helicopter is hovering, the rotor downwind generated by the main rotor 2 of the helicopter deteriorates workability. An object of the present invention is to provide a helicopter capable of solving the above problems.

[0010]

[Means for Solving the Problems]

A first means of the helicopter according to the present invention is a helicopter having a rescue device, which has a hoist strut 37, a hoist 38, a rope 39, and a life preserver 48, and a shaping member is provided on an upper portion of the hoist strut on the side of the body. 36, 41, or the fixed type deflector plate 19 or the covers 42 to 47 are provided, and the protection device 33 is provided at the tip of the rope 39. 2nd means The helicopter which concerns on this invention is a helicopter which has a rescue device. It has the hoist support | pillar 37, the hoist 38, the rope 39, and the life preserver 48, and is a variable type on the upper part of the said hoist support | pillar on the side of the fuselage. The deflector plate 10 is provided, and the protection device 33 is provided at the tip of the rope 39. It is characterized in that it rotates around and is used as a deflector plate by making it bulge only when necessary, and put in a housed state when it is unnecessary.

[0011]

[Function] A shaping member 36 is provided on the upper side of the body of the helicopter.
By installing 41, it is possible to shift the blowdown generated by the rotation of the main rotor to the outside. Similarly, by attaching the fixed type deflector plate 19 or the variable type deflector plate 10 to the lateral upper part of the body of the helicopter, similarly to the above,
The downwind generated by the rotation of the main rotor can be shifted to the outside.

Alternatively, by installing a cover from the upper side portion to the lower side portion of the body of the helicopter, it is possible to shift the blowdown generated by the rotation of the main rotor to the outside.

When the downwind of the main rotor is shifted to the outside, the rope 39 does not enter into the downwind of the main rotor, so that the swing 56 is small. . Therefore, it is possible to prevent the rope 39 from coming into contact 57 with the body 5 of the helicopter, and the rope 39 can be safely lifted by the hoist 38.

In this way, the blow-down generated by the rotation of the main rotor 2 is shifted to the outside, and further, as a protection device 33 as shown in FIG. 16, a life-saving device 48 is attached to the tip of the rope 39 to be lifted by the hoist 38. If a cone-shaped protection device is attached to the part where
It is possible to further reduce the effect of downwash caused by the rotation of the. The person rescued by these can be protected safely from the open air.

Further, as described above, by providing the rectifying member, the deflector plate, and the cover, it is possible to reduce the circulation flow when the helicopter is hovering near the ground.
