Description

DETAILED DESCRIPTION OF THE INVENTION This application is filed under patent application No. 53-128025. using the invention of

Make the balloon (1) strong and double it as a pressure tank (2).

Airships and other objects are raised and lowered by having a telescopic chamber inside and pressurizing or releasing air (more precisely, atmospheric air) into the chamber.Currently, lightweight and strong materials for balloons can be easily obtained. It is believed that this invention will continue to improve in the future, so we have filed an application for this invention taking these into consideration.

Currently manufactured in 9 countries in Japan. Lumirror (Tokuyama Soda product) is 0.1 mm thick and 10 cm wide, and when tested for tension, it withstood more than 100 kg and finally cut at 1624 g, but there was almost no elongation at Iook. If you correct it to the standard, it will be 10kg/-.

It has a strength close to that of light metal materials, and its specific gravity is approximately 1.4. If this were to be made into an air sac (same as the balloon of the parent's wish), one 0.1 mm thick sheet would be sufficient, but since it would be traveling in the air with 9 people on board, a large safety factor should be taken, and 3
I'm thinking of using a single piece or three pieces of 0.2mm, but if it's this strong.

It is safe to apply internal pressure, and if we estimate from the experimental results what the maximum internal pressure will be, it will be larger in volume than the pressure tank in (2), so the unit pressure will be smaller, 10
The maximum value is 0.07k when calculated with an air bag of ,000rrl.
g/cd, and all you need is this extra pressure resistance.

This level can withstand even ordinary products, but it is suitable for designing commercial products. Looking at the safety factor, we can conclude that a strength of 9 is sufficient.

Also, since airships navigate on their own, the diameter should be made small and streamlined, and the length should be made longer.However, the smaller the diameter, the greater the resistance to internal pressure, so considering that it will be effective for future airships. Yes.

In addition, light metals can also be made into strong materials, with a strength of 5o kg/rmA.
It is said that the above items can be made, and we can predict that by combining new materials such as carbon fiber, we can make any number of strong and light items.

To explain the present application, the air bag (1) in Figure 2 is filled with light gas such as helium (hereinafter referred to as light gas) and is used to suspend the entire ship. ) by installing a retractable tuft, and press air into the shoulder meat using an air compression pump (3), or by opening a valve (4) and releasing it.
1) The light gas inside is compressed or expanded to move up and down, and (5) carries people and equipment.

It is shaped like a boat so that it can be lowered onto the water using a gondola. (2) The tassel can be made of something like a rubber balloon, but it should be made of polymer to prevent air and light gas from mixing.

You will need something with strong tension.

To explain how it works, 1. For example, if you are currently floating 500 meters in the air, (2) there is a small amount of air in the layer. To descend at this time, air is forced into the layer by the compressor (3), and the chamber (2).

As it swells and becomes larger, it pressurizes the light gas inside (1), so this volume is reduced, and the rate of descent becomes an arrow in proportion to the reduction, and it descends.

When ascending, the compressor is stopped and the valve (4) is opened. Air is released due to the internal pressure, and light gases diffuse, increasing volume and increasing buoyancy, allowing the boat to ascend.

The internal pressure of the air sac (1) is minimal to maintain its shape while driving.

The goal is to maintain the pressure at around 1.2 atmospheres.

In addition, when air is introduced into chamber (2) and light gas is pressurized.

The air sac (1) also swells somewhat, but since it has elasticity, it balances out and stops at the point of pressure.

At this time, it will require slightly less air than a copper body, but if it is a rigid airship, etc., the distortion will be less.

You'll probably need less air.

4. What differs from the additional related petition is that the outer skin of the balloon (same as the air bag of an airship that contains light gas) is made stronger, and this is used instead of a pressure tank, and the inside of the balloon is Nifusa (
2), the gas compression pump compresses air, not light gas, so there is no difference in the basic point that it moves up and down by changing the volume of light gas.

Claims (1)

[Claims] As explained (a method that makes the air sac strong and has an expandable chamber inside it, and by pressurizing or releasing air into it, changes the volume of light gas and allows airships etc. to go up and down.
