pressure suit

An astronaut wears a pressure suit inside the spacecraft.

Definition

Noun: A pressure suit is a protective garment designed as an inflatable, full-body suit. Its primary function is to maintain a stable, life-supporting atmospheric pressure around the wearer's body in environments where the external air pressure is dangerously low or absent, such as in high-altitude flight or space.

Usage

The term is used specifically to describe a specialized, technical garment for aviation and aerospace. It is a compound noun where "pressure" modifies "suit" to specify its purpose. * Pilots wear a pressure suit when flying at extreme altitudes. * The astronaut's pressure suit was checked thoroughly before the mission. * Modern pressure suits are essential for protection in case of cabin depressurization.

Advanced Usage
  • Partial-pressure suit: A specific type of pressure suit that uses mechanical counter-pressure (tight straps) rather than full inflation to protect the body. It is often used for high-altitude reconnaissance aircraft.
  • The engineering of a pressure suit involves complex systems for breathing, temperature regulation, and mobility.
Variants and Related Words
  • Spacesuit: A more complex, self-contained version of a pressure suit designed for extravehicular activity (spacewalks) outside a spacecraft, providing additional life support.
  • G-suit (anti-g suit): A related garment that applies pressure to the abdomen and legs to prevent pilots from losing consciousness during high-acceleration maneuvers, but it does not protect against low atmospheric pressure like a full pressure suit.
  • Flight suit: A general term for a one-piece garment worn by pilots; it may be worn under or integrated with a pressure suit.
Synonyms
  • Protective flight garment
  • High-altitude suit
Related Phrases/Concepts
  • Cabin pressure: The maintained air pressure inside an aircraft or spacecraft cabin. A pressure suit is needed if this fails.
  • Depressurization: The loss of cabin pressure, which is the emergency scenario a pressure suit is designed to mitigate.
  • Life support system: The integrated systems (often part of or connected to a pressure suit) that provide breathable air and temperature control.
