JPS6076481A - Floating impeller utilizing hood - Google Patents

Abstract

PURPOSE:To enhance the floating efficiency of an impeller, by providing such an arrangement that air is introduced into a parachute shape hood by means of the impeller, and is then directed downward to obtain bouyancy. CONSTITUTION:The ambient air is introduced below a hood 1 formed in a parachute shape. An impeller 3 introduces the ambient air into the hood when it is rotated. The rotation of the impeller 3 causes the air sucked from a suction port 2 to be scattered around under centrifugal forse so that air flow takes place horizontally. The direction of this air flow is changed downward by means of the hood 1 so that hood 1 is exerted with an upward impluse corresponding to a variation in the momentum of the air flow, thereby bouyancy may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION There are many ways to create buoyancy. (1
) Those that utilize the density difference of gases (balloons), (2) Those that focus on the pressure difference between the inside and outside (hovercraft)
There are four types: (3) those that use gas injection (rockets), and (4) those that use propellers (helicopters).

(1) is not suitable for practical use because it is bulky, takes up a lot of space, and is easily affected by wind. (2) is to force air between the bottom of the ship and the water surface and prevent it from escaping to increase internal pressure and obtain buoyancy. Therefore, when a ship rises a little higher than the water surface, the air inside leaks and the internal pressure drops. Not suitable for flying high.

(3) is disliked because too much energy is consumed by heat, making it impossible to obtain good efficiency. The mechanism would also be exaggerated, making it impossible for general use. Although method (4) is more efficient than this jet method and has a relatively simple mechanism, it is still unsatisfactory when considering the effective use of energy.

As proof of this, there is still no one who has been able to spin a propeller and fly up on their own. Even if it could fly, it would require tremendous strength. For example, if the effort required is equivalent to carrying three people of the same weight as you up a flight of stairs, then the efficiency of the propeller is 1/4. At most, it would take two people to carry him up the stairs, so even if he could fly with his own power, the efficiency would be about 1/3.

The aim of the present invention is to improve this flotation efficiency.

This will be explained in the accompanying drawings. First, a canopy (1) shaped like a parachute is installed, and outside air is taken in under the canopy. Outside air is drawn in by rotating the rotary vane (3). When turned, the outside air sucked in through the intake port (2) is scattered around by centrifugal force, creating a horizontal wind. If this airflow is changed downward by the hood, the hood will receive an upward impulse equal to the change in momentum of the flow. In this way, buoyancy can be obtained.

With this method, the rotating blades do not have to turn as fast, so the turbulence that occurs with propellers is less likely to occur. Therefore, the entire flow of air flowing in from the intake port becomes a lifting force, resulting in extremely high efficiency.

It's not just about efficiency. It also requires less power. In the case of a helicopter, if you stop the propeller, you will fall at high speed, so you have to keep the propeller spinning. However, if you use the hood, you can fall slowly, so you can stay afloat even when you are rotating the feathers at rest. In other words, it can fly with less power than a propeller.

The best thing about it is that it is safe.

In the event that the rotor blades stop due to some accident and the aircraft loses lift, the hood serves as a parachute. Since it is not dangerous, it is ideal as a sports equipment for flying in the sky like a hang glider.

Also, by sending it along with radio signals, it can be used as an unmanned aerial vehicle to transport packages from building to building, from island to island, from flatlands to mountain peaks.

It can also be used as a toy. The Helicopter, a toy that can be flown using batteries and a motor, cannot be made using traditional methods. That's why toys like UFOs are not yet commercially available. However, according to the present invention, this is also possible. The figure shows the exact appearance of a UFO. Even when it flies, its posture is always kept horizontal due to the gyroscope effect of the rotating blades inside. This is also one of the advantages.

This invention has a dream. There is fantasy.

This is completely unprecedented.

(2) is a rotating blade, and (3) is an intake port.

Claims (1)

[Claims] A floating vane that uses rotating vanes to draw air into the inside of a parachute-shaped canopy and redirects the flow downward, thereby obtaining buoyancy.
