THE ANTI-G VALVE IS A LIFE SUPPORT EQUIPMENT AND SHALL PROTECT THE PILOT AGAINST HIGH-G LOADS BY USING THE ANTI-G SUIT. DEPENDENT ON THE +Gz THE VALVE CONTROLS THE PRESSURE IN THE ANTI-G SUIT AND DELIVERS AN OVERPRESSURE TO THE MASK FOR FORCED BREATHING.
All high performance aircraft pulling high-G must be equipped with an Anti-G Valve. Without such a device, the pilots are not able to sustain high-G of more than +4 G.
The aircraft industry provides such anti-G systems in form of hardware-controlled valves. These react on aircraft induced G-loads and have a fixed pressure versus Gz load characteristic.
The AMST software controlled anti-G system represents an alternative to such standard aircraft anti-G systems for use in human centrifuges or other earth-based simulators.
Pressures in the trousers and in the vest are different, mainly in the ratio of 10:1.
THE BENEFIT OF USING THE SOFTWARE CONTROLLED ANTI-G VALVE, IN A HIGH PERFORMANCE HUMAN CENTRIFUGE (HTC) OR ANY OTHER FLIGHT SIMULATOR, IS THE HIGH FLEXIBILITY OF THE SYSTEM AND THE ADJUSTMENT OF THE CHARACTERISTICS TO ANY OTHER TYPE OF AGV.
It can be used as a standard AGV or AGV including Positive Pressure Breathing (PPB)
Has proven safety features to prevent overpressure to the pilot and his equipment - especially to protect the pilots’ lungs
Gives the user the advantage of different settings for different suits and for research
Is available whilst original anti-G valves are aircraft equipment and hardly available for civil use or even for the use in equipment for high-G training
Requires no ITAR approval because as only standard industrial components are used
AN UNIVERSALLY COST EFFICIENT SOLUTION
Breathing Air System
The air compressor delivers breathing air according to international standard for breathing air and is oil-free. The piping is made of stainless steel.
A supply panel is installed for three separate supplies with different pressure for trousers, vest and mask. The operator, if required, can switch ON/OFF each supply line externally.
Each supply line consists of a pressure reduction valve and a pressure sensor installed between the Electronic Pressure Regulator (EPR) and the Personal Equipment Connector (PEC) for adjustment and monitoring. The supply line to the mask has an additional emergency valve for pilot safety. In case of a supply failure, this valve will supplies the pilot with breathing air.
Graphic User Interface - GUI
On the GUI the operator can preselect the cut-in point, the pressure, the ratio between trousers, vest, mask and the characteristic of the slope.
A Programmable Logic Controller (PLC) is installed for real-time control of the pressure regulators, for several checks like operating reliability and for the redundant safety system.
The safety critical aspect of the system is solved by electric hardware like pressure switches and relays. Each pressure line has a factory adjusted and sealed pressure switch, which cuts off the power supply of the system in case of a pressure overshoot, fault in a regulator, and has an anti-G stop button for emergency.
