Anti-Gravity Systems

Anti-G System

Supplies air pressure for inflating the aircrew’s Anti-G Suit

• Worn to counteract the effect of gravity “G” forces on the aircrew

• Relieves stiffness and physical tension

Effects of '“G”

• Excessive fatigue

• Decreased Alertness

• Blackout

• Unconsciousness

• Death

Anti-G System Description

Contains a Pressure Regulator, which automatically regulates air to the Anti-G Suit

Suit Inflation

• Positive vertical force of 1.75 “G”, the activating weight begins to move down against the main spring

• Downward movement of the valve piston closes the opening between the outlet port and the suit vent port, connects the inlet port to the outlet port, directing pneumatic pressure into the suit

Constant “G” Condition

The demand valve closes under pressure of the heavier lower spring, while the exhaust valve remains closed by the activating weight

Suit Exhaust and Static Condition

As the positive forces decrease toward 1.75 “G”s, the piston will raise, dumping pressure from the suit through the suit exhaust into the cockpit

Maximum pressure of the Anti-G Suit is ___ psi
