Innovative high flow rate constant pressure valve for inert gas discharge from pressurized vessels

Topic description

Specific Challenge:

High pressure inert gas storage vessels are used for a novel water mist and inert gas based fire suppression system for aircraft cargo compartments, within WP2.3. Other than today’s commonly used Halon based fire suppression systems, the mass flow rates and supply pressures for these systems are much higher, resulting in a series of challenging requirements which are not met by today’s available system.hardware. The applicant shall develop an innovative high pressure and very high mass flow valve for inert gas, which is capable of providing a constant output pressure over a broad spectrum of input pressures. Any proposed solution shall meet the aviation specific requirements such as reliability, environmental requirements and lightweight design, in addition to the extreme performance requirements necessary for an inert gas fire suppression.
