pressure suitn. A garment that is worn in high-altitude aircraft or in spacecraft to compensate for low-pressure conditions.pressure suit n (Aeronautics) an inflatable suit worn by a person flying at high altitudes or in space, to provide protection from low pressure pres′surized suit′
n. an airtight suit that can be inflated to maintain approximately normal atmospheric pressure on a person in space or at high altitudes. Also called pressure suit. [1955–60] pressure suit1. Partial--A skin tight suit which does not completely enclose the body but which is capable of exerting pressure on the major portion of the body in order to counteract an increased intrapulmonary oxygen pressure.
2. Full--A suit which completely encloses the body and which a gas pressure, sufficiently above ambient pressure for maintenance of function, may be sustained.Thesaurus| Noun | 1. | pressure suit - protective garment consisting of an inflatable suit for space or high altitude flyinganti-G suit, G suit - worn by fliers and astronauts to counteract the forces of gravity and accelerationprotective garment - clothing that is intended to protect the wearer from injuryspacesuit - a pressure suit worn by astronauts while in outer space |
pressure suit
pressure suit[′presh·ər ‚süt] (aerospace engineering) A garment designed to provide pressure upon the body so that respiratory and circulatory functions may continue normally, or nearly so, under low-pressure conditions such as occur at high altitudes or in space without benefit of a pressurized cabin. Pressure Suit a pilot’s personal equipment for protection against the dangers of low barometric pressure in case of depressurization of the cockpit at altitudes of more than 12-15 km. The pressure suit is a flight suit with an oxygen mask having surplus pressure or with a pressure helmet. It should exert even counterpressure over the entire surface of the body, not hinder the pilot’s movements, and be air- and vapor-tight. The pilot must be able to put it on and take it off without help from others. The maximum flight elevation in the pressure suit depends on the duration of the flight, how well the suit fits, and the physical strain on the pilot. The principle of action of the pressure suit is based on the fact that the surface of the body is subject to mechanical squeezing with specific pressure equal to the pressure of gas in the lungs. This is done by tension devices with pneumatic chambers inside. When they fill with gas, the chambers straighten out, increase in diameter, and stretch the fabric of the suit. IU. F. ZAV’IALOV pressure suitA skintight suit that may or may not enclose the body fully and can exert pressure on the major portion of the body to counteract an increased intrapulmonary oxygen pressure. The suit permits the respiratory and circulatory functions to take place normally, or near normally, under low-pressure conditions. The suit is used for high-altitude flying where there is a possibility of explosive decompression. See also partial pressure suit.pressure suit
