Pneumatics is the use of pressurized gas to affect mechanical motion.This field deals with the use of pressurized gas to affect mechanical motion.
Examples of pneumatic systems:
# Air brakes on buses and trucks, trains
# Compressed-air engine and compressed-air vehicles
# Gas-operated reloading
# Pneumatic actuator
# Pneumatic air guns
# Pneumatic cylinder
# Pressure regulator
# Pressure sensor
and much more.
Gases used:
compressed air is used by Pneumatic systems in fixed installations such as factories. a small quantity of oil and moisture are added to avoid corrosion . nitrogen - often referred to as OFN are used by Factory-plumbed, pneumatic-power users. Compressed oxygen is never used in pneumatically powered devices as it accelerates combustion.
Advantages of pneumatics
-Simplicity of Design And Control
-Storage
-Reliability: they tend to have long operating times. .
-Safety
Pneumatic power generation and control
The turbine engine is a generator of high-speed gas aimed to provide thrust for the aircraft.In this kind this kind of compressed air generation:
a)the system needs a regulation, because bled air conditions depend on engine
functioning conditions
b) a reduced amount of air can be bled from the
compressor to avoid significant breakdown in engine performance.
