Pneumatic Systems for Aircraft

Sushree Sunena

In the past, several aircraft manufacturers installed a high-pressure pneumatic system (3,000 psi) on their planes. The Fokker F27 was the final airplane to use this sort of technology. These systems work similarly to hydraulic systems, except instead of using a liquid to convey power, they use air. Both pneumatic and hydraulic systems employ restricted fluids and are comparable devices. The phrase confined refers to a situation in which you are imprisoned or totally contained. The term “fluid” refers to liquids such as water, oil, or anything else that flows. Liquids and gases are both called fluids because they flow; yet, the properties of the two are vastly different. Liquids are nearly incompressible; no matter how hard you compress a quart of water, it still takes up roughly a quart of space.
