KEY VOCABULARY

Word Meaning

pneumaticcontaining or operated by air or gas

under pressure

pneumatic

system

a fluid power system which transmits

force through compressible air

compressed airair that is at pressure more than

atmospheric pressure

vacuum a space entirely devoid matter

valvea device for controlling the passage of

liquid or air through a pipe, duct, etc.

innovation a uniquely new idea, device or method

Air is all around us even though we can’t see or feel it. Air

presses on our bodies with a great force. We don’t feel this

because the air inside our bodies is pushing back equally

hard. Air pressure is know as pneumatics and is very

important.

Air pressure

PNEUMATICS - DEFINITION

• The study of pneumatics deals with system operation

with air to impart power or to control power.

• The term pneumatics is derived from the Greek word

pneuma, meaning wind or breath.

• Pneumatic power is the power that is transmitted by

pressurized/compressed air.

A BRIEF HISTORY OF PNEUMATICS

Most of the modern machinery we see today uses

some type of pneumatics to make it function.

1897

Pneumatics was discovered in

the 16 th century by a German

physicist and engineer named

Otto.

He experiment with air and the

idea of compressing it and

invented the first vacuum pump.

that used pneumatic force.

INNOVATION AND THE FUTURE OF

PNEUMATICS

HOW DOES THE HYPERLOOP WORK?

1. There’s a tube (tunnel) from point A to B.

2. The air from the tube has been removed

(low air pressure is present inside the

tube).

3. Then there are some pods inside that

tube.

HOW DOES THE HYPERLOOP WORK?4. These pods will levitate and move forward tracking friction and

reducing drag (as the air has already been removed).

5. For some air left in that tube, compressor fans installed in the

front of the pods will suck in the air and push them via air bearing.

6. Anything can be put the pods, depending upon its dimensions

and capacity.

7. These pods will move from point A to point B, moving the things

(or people) in them.
