ROTC study guide

compressed air taken from the compressor stage of a gas turbine upstream of its fuel-burning sections.

• Bleed air

• Differential pressure

• Explosive decompression

• Positive pressure

The difference in pressure between two given points.

• Ambient pressure

• Differential pressure

• Rapid decompression

• Windblast

The pressure on an object is the pressure of the surrounding medium, such as a gas or liquid, in contact with the object.

• Explosive decompression

• Differential pressure

• Ambient pressure

• Bleed air

Uncontrolled decompression is an unplanned drop in the pressure of a sealed system ( occurs in less than .5 seconds)

• Explosive decompression

• Ambient pressure

• Ambient pressure

• Positive pressure

Uncontrolled decompression is an unplanned drop in the pressure of a sealed system ( lasting greater than .5 seconds) 

• Centrifuga

• Differential pressure

• Explosive decompression

• Rapid decompression

a thin tube inserted into a vein or body cavity to administer medicine, drain off fluid, or insert a surgical instrument.

• Cannula

• Static line

• Centrifugal

• Ambient pressure

is a pressure within a system that is greater than the environment that surrounds that system

• Ambient pressure

• Differential pressure

• Positive pressure

• Windblast

tightens around the limbs and torso to protect against swelling caused by low-pressure exposure until the pilot could descend to a lower altitude, unlike the full pressure suit the partial pressure suit does not cover the full body. 

• Partial pressure suit

• Full pressure suit

• Windblast

• Centrifugal

a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even breathing pure oxygen at positive pressure.

• Partial pressure suit

• Parachute

• Full pressure suit

• Cannula

a device used to slow the motion of an object through an atmosphere by creating drag

• Static line

• Windblast

• Flight simulator

• Parachute
