Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a flight vehicle for carrying people and cargo.

[0002]

2. Description of the Related Art Conventionally, helicopters that fly by lift due to the rotation of a rotor make use of their characteristics to take off and land in a narrow space to carry people and goods, or to fly at low altitudes.
It is possible to fly in a small turn, such as by resting in the air to rescue a victim.

[0003]

However, the rotation range of the rotor is quite wide, and a helicopter accident occurs when the operator makes a tight turn without being aware of the existence of the rotor. In other words, the cause is a crash caused by the helicopters being interviewed (due to a disaster, etc.) approaching each other and their rotors touching and damaging each other, and a crash caused by the rotors touching other things. In this case, even if the rotor is in slight contact, its rotation speed is high, so that the rotor is seriously damaged, resulting in a serious accident. The current situation is that specific preventive measures have not been taken for the causes of these accidents.

Therefore, the present invention protects the rotor to prevent a fall accident due to contact damage of the rotor, and
The purpose is to provide a flight vehicle that can slowly descend even if an engine trouble occurs to protect human lives.

[0005]

In order to achieve the above-mentioned object, a flight vehicle according to the present invention has a fixed ring guide arranged along an outer peripheral edge of a rotation locus of a rotor, and is fixed to the ring guide. A roller is provided at the outer end of the rotor so as to movably contact or approach the roller.

Further, a plurality of windows are provided in the fixed blade, and a fixed ring guide is fixed around the windows, and further, the outer peripheral edge of the rotation trajectory corresponds to the ring guides in each window. A rotor is provided, and rollers that come into contact with or come close to the ring guide so as to be rotatable are provided at the outer ends of the rotors.

In this flight vehicle, a rotor 5 is attached to a tip of a shaft 3 of an engine 2 incorporated in a streamlined airframe 1. The fixed ring guide 4 is attached along the outer peripheral edge of the rotation path of the rotor 5.

The rotor 5 includes a plurality of elongated columnar cores 5a, a plurality of fan-shaped blades 5b provided along the cores 5a at a predetermined angle, and a plurality of cores. 5
and a connecting block 10 that is fixed to the tip of the shaft 3 by radially connecting a. Further, pivot shafts 8 extending in the axial direction of the core 5a are fixed to the outer ends 9 of the cores 5a of the rotor 5. Rollers 6 having a diameter larger than that of the core portion 5a are mounted on the pivot shaft 8 so as to be rollable via bearings or the like.

The outer peripheral edge of the above-mentioned rotation orbit of the rotor 5 is
That is, it is the rotation path of the roller 6 attached to the outer end 9 of the rotor 5 core 5a. A fixed ring guide 4 having a U-shaped cross section is arranged so as to cover the rotation path of the roller 6. Specifically, the ring guide 4
Has an opening having a U-shaped cross section facing the shaft 3, and a lower surface 11 thereof is firmly connected to the upper portion of the machine body 1 by a plurality of supporting columns 7 by welding or the like, and is horizontally supported. Has been done. A tail rotor 12 for anti-torque is arranged on the vertical plane at the rear of the body 1.

FIG. 3 shows a state in which the rotor 5 is stopped. At this time, the core portion 5a of the rotor 5 is slightly bent downward, so that the roller 6 at the outer end portion 9 of the core portion 5a has an inner bottom surface 13 of the ring guide 4. Abut.

When the rotor 5 is rotated by the rotational driving of the engine 2, the rollers 6 ... Roll on the inner bottom surface 13 of the ring guide 4. Then, as shown in FIG. 1, when the outer ends 9 of the cores 5a are lifted by the lift force received by the blades 5b, the rollers 6 move away from the inner bottom surface 13 and rotate around an orbit.

At this time, the roller 6 rotates in close proximity to the inner bottom surface 13 and the inner upper surface 14 of the ring guide 4, that is, the roller 6 rotates without contacting the inner bottom surface 13 and the inner upper surface 14.
In order to enable the above, predetermined gaps M, M are provided between the roller 6 and the inner bottom surface 13 and between the roller 6 and the inner top surface 14. Therefore, the rotor 5 smoothly rotates without generating frictional resistance with the ring guide 4, and the body 1 rises and flies.

As described above, in the flying vehicle of the present invention, the outer peripheral edge of the rotor 5 rotating at a high speed is surrounded by the ring guide 4 to protect the rotor 5 from obstacles approaching from the outside. Further, FIG. 4 shows a state where some obstacle approaching the aircraft 1 in flight contacts (lightly) the ring guide 4 of the aircraft 1 by any chance.

FIG. 1A shows a state in which an obstacle contacts the upper portion of the ring guide 4 and an external force F is applied thereto. At this time, the rotor 5 and the roller 6 are protected from obstacles by the ring guide 4. Then, the ring guide 4 which receives the external force F is pushed down together with the support column 7 by the impact, but the roller 6 of the rotor 5 abuts on the inner upper surface 14 of the ring guide 4 and rolls, so that the rotation of the rotor 5 Is maintained. That is, the aircraft 1 can continue to fly safely without crashing.

Further, FIG. 2B shows a state in which an obstacle contacts the lower part of the ring guide 4 and an external force F is applied thereto. At this time, the ring guide 4 that receives the external force F is pushed up by the impact, but the roller 6 of the rotor 5
Is rolling on the inner bottom surface 13 of the ring guide 4 so that the rotor 5
Is maintained and the aircraft 1 can continue to fly. Further, FIG. 3C shows a state in which an obstacle contacts the outer side portion of the ring guide 4 and an external force F is applied. At this time, the ring guide 4 which receives the external force F is dented inward by the impact, but the rotor 5 is protected and the rotation is maintained, so that the airframe 1 can continue to fly.

In the unlikely event that the ring guide 4 is damaged (dented) so much that the rollers 6 cannot rotate on their own orbits, the rollers 6 ...
It is desirable that all the pivot shafts 8 of the rollers 6 are broken to keep the rotor 5 rotating to prevent the body 1 from crashing, and the pivot shafts are supported by a predetermined load force. 8
Set so that it will break.

Further, the rotor 5 is arranged in each window portion 16 (of the fixed blade 15) so that the outer peripheral edge of the rotation trajectory of the rotor 5, that is, the rotation trajectory of the roller 6 corresponds to the ring guide 4. Has been done. The engine 2 that rotationally drives the rotor 5 is arranged below each window 16 ...
The lower surface (23) of the fixed wing (15) is connected and held in a hanging shape to a holding column (22) vertically extending from the vicinity of the outer peripheral edge of the window section (16).

When the shafts 3 ... Of the respective engines 2 ... Are rotationally driven, the rotors 5 ... At this time, in order to cancel the anti-torque caused by driving the rotor 5, the adjacent rotors 5 and 5 are rotated in opposite directions. Then, the machine body 1 is lifted by a large lift force caused by the rotation of the rotors 5 ... And can fly. Further, as shown in the figure, the flight vehicle of the present invention can be easily provided with a plurality of (four) rotors 5 by providing the fixed blades 15 having a relatively large area, and the plurality of rotors 5 can be generated. The large lift makes it possible to levitate even a considerable weight. Therefore, the size of the machine body 1 can be increased, and many people and a large amount of cargo can be carried at once.

On the other hand, as a safety measure, the ring guides 4 protect the outer peripheral edges of the rotors 5 that rotate at high speed, and the fixed blades 15 connect and protect the ring guides 4 so that the rotors 5 ... Is protected from obstacles approaching from the outside and can fly safely.

However, in the unlikely event that the rollers 6 are unable to rotate on their own orbits due to damage to the ring guides 4, all the pivot shafts 8 of the rollers 6 ...
It is desirable to prevent the crash of the airframe 1 by breaking the shaft to keep the rotor 5 rotating. Further, when some or all of the engines 2 ... Stop due to some reason, the large-area fixed wing 15 receives an air resistance force and glides slowly like a glider to land, and the aircraft 1 escapes from a crash. be able to. At this time, the rudder 24 and the elevator of the vertical stabilizer 20
