  • Publication number: 20130310633
    Abstract: —The suit according to the invention consists of a sheath of an expansible material, which has compartments formed by virtue of the sheath being doubled. A strip of textile material is applied to the inside, or outside, of the sheath. These compartments consist of the same material as the sheath or of an expansible knitted fabric. Flexible tubes which expand under pressure are introduced into these compartments. The first-mentioned compartments, with material which can expand on one side, act as so-called spacers and act as displacers for tightening the protective suit over the wearer's body. The second-mentioned compartments act as muscles and press locally onto the wearer's body. The compartments are drawn together and tighten the sheath to generate an altitude-optimized pressure. These second-mentioned compartments tighten the acceleration protection suit to an increasing extent until the tension ? around the wearer's body builds up the internal pressure.

    Abstract: The invention enables testing of nearly all aircrew equipment including COMBAT EDGE system components which include a mask, a G-suit, communication systems, and a goggle. A gas system includes an input filter, a first compressor comprising at least one blower, preferably three blowers connected in series, a second compressor, a first flow sensor, a second flow sensor, a first flow valve, a second flow valve, a regulator, a first pressure sensor, a second pressure sensor, a first pressure valve, a second pressure valve, and a controller. The second compressor produces a lower flow at a higher pressure than the first compressor. When the G-suit inflates, initially there is a large change in volume without much change in pressure, and then, as the G-suit fills and becomes firm, the change in volume slows down and the rate of the pressure increases. A normal breathing test, a preflight test, a fit test, a G-suit leak test and two dynamic flow leak tests are conducted.

  • Patent number: 6993791
    Abstract: An altitude protection device for an acceleration protection suit having a plurality of liquid-filled veins is comprised of a bladder inserted in a pocket. A spacer fabric that is non-compressible under the loads to be provided is enclosed in the pocket and defines a minimum volume inside the bladder. The bladder is closed off or opened relative to surrounding air in the aircraft cabin via a valve that is opened if a rate of pressure change in the cabin is less than or equal to a presettable maximum value, and closed if the rate of pressure change is greater than the value. If the valve closes and the pressure falls further, air located in the bladder inflates the bladder and pocket, increasing tensile stress in the fabric, and thereby raising the internal pressure of the veins resulting in increased internal pressure in the entire acceleration protection suit.

  • Patent number: 6387704
    Abstract: For use in a sorption analysis system, a method compensating for measuring error due to the time-dependent evaporation of liquid coolant and the resulting change in the level of the coolant and temperature increase around the stem of the sample cell, during a gas sorption analysis of a sample in the sample cell. This error compensation does not inhibit coolant evaporation and is without recourse to mechanical means or other physical contrivances for causing the system to act as if the coolant were not evaporating. This method employs fixed and time-dependent data, including: changing coolant level and sample cell stem temperature changes, both of which can be obtained off-line, cold zone volume changes, and volumes of adsorptive gas transferred into the sample cell, to generate progressive error correction; whereby, system output is being corrected throughout the duration of the sorption analysis.

  • Patent number: 6325754
    Abstract: The active part of the suit comprises in part one layer (3, 4) facing the body and another one facing away from it, both of a gas-tight, low stretch textile material, which are joined together at connecting positions (6) by gluing, welding or sewing and thereby create hollow spaces (5), which are connected together via valves (18) and can be put under pressure. Between the regions, which comprise the layers (3, 4)—bands (11, 12)—connecting parts (7) are arranged, which transmit tensile forces only. If the hollow spaces (5) are put under a gas pressure proportional to the z-acceleration, then the suit builds up a compensating applied pressure and thus frees the organism of the pilot from the loading effects of such accelerations. By a suitable choice of the width of the bands (11, 12) in conjunction with the radius of the enclosed part of the body a compensating pressure to the hydrostatic pressure, proportional to the acceleration, of the body fluids can be set up.

  • Patent number: 5314402
    Abstract: Inflation pressure of an aircrew G-suit is set by a servo-pressure which controls movement of inflation gas supply and vent valves 126 and 127, respectively. Servo-pressure is regulated by a torque motor controlled valve 124, 125 which receives a servo-demand signal from an electronic control unit (ECU) 123. The ECU receives an inflation pressure demand signal P.sub.DEM from an aircraft systems computer 120 which stores schedules of G-suit inflation pressure against increasing acceleration and decreasing cabin ambient pressure. The computer is programmed to look-up and output the higher one of values for inflation pressure dependent upon values of acceleration signals G.sub.Z and cabin ambient pressure signals P.sub.AMB input to the computer by sensors 121 and 122, respectively.

  • Patent number: 5247926
    Abstract: A breathing gas regulator for regulating delivery of breathing gas to an aircrew member wearing a liquid filled G-suit includes a relay valve having a diaphragm mounted valve plate for sensing G-suit hydrostatic pressure. A bleed of breathing gas is supplied to the relay valve by way of a pneumatic link and is vented to ambient through a vent outlet. As G-suit hydrostatic pressure rises due to increasing G-load the valve plate moves towards closing the vent outlet. Above a predetermined G-load, with the vent outlet closed, a pneumatic signal is generated in the pneumatic link and is applied to an end face of a valve controlling outflow from a breathing-pressure control chamber so that pressure in the control chamber increases to set a breathing gas pressure at the regulator outlet appropriate to positive pressure breathing.

  • Patent number: 5127896
    Abstract: This invention is an integrated anthropomorphic g-suit, with a breathing regulator and means for protecting the user of the suit from hostile environments. The suit has a flexible, distensible, impermeable inner liner that conforms to a user's body, and a flexible, impermeable, nondistensible outer liner that fits over the inner liner, to trap a thin layer of fluid between the inner and outer liners. The suit acts as a tank of fluid, so that the suit exerts a hydrostatic pressure on the user's body, preventing blood from draining from the user's head, when the user is subjected to acceleration. The breathing regulator is responsive to the pressure of the fluid in the suit, such that the pressure of the breathing gases being supplied to the user is approximately the same as the fluid pressure in the thoracic region of the suit. The regulator can vary the pressure of the breathing gas, automatically as a function of ambient pressure.

  • Patent number: 4959047
    Abstract: A flexible lower body negative pressure (LBNP) anti-G suit for protecting against the adverse effects of -G.sub.z acceleration is disclosed. Conventional anti-G suits protect against the adverse effects of +G.sub.z acceleration. Accelerations in the negative z direction, -G.sub.z, can also cause adverse physiological effects and, additionally, severely unpleasant subjective sensations. LBNP has been used in the past to alleviate the somewhat similar physiological effects of weightlessness in space. It has also been used with merely limited success to treat various medical problems. The present invention provides an improved LBNP suit that successfully alleviates the adverse physiological and subjective effects of -G.sub.z accelerations. Applying LBNP to an aircrew member increases venous vascular volumes in the lower body and reduces the otherwise increased pressures in the upper cardiovascular system.

  • Patent number: 4906990
    Abstract: A system and method for alerting a crew member if his anti-G system is not at the proper pressure during a flight. Flight condition sensors and an anti-G suit pressure sensor input data to a computer controller. The controller selects a pressure for protecting the crew member against blackout based on the input and data stored. The controller generates a signal to change the pressure in the anti-G suit to the selected pressure. The controller monitors the pressure status of the anti-G suit and rate of pressure change over time after the signal is generated. If the anti-G suit does not reach the selected pressure within a selected time, an alarm is provided to the crew member. Early warning, caution or failure alarms are generated if the suit does begin to inflate immediately or if it fails to reach a threshold pressure after a threshold time.
