  • Dual-pressure source aircraft pneumatic system with pressure relief
    Patent number: 11448126
    Abstract: A bleed air system for a pneumatic system of an aircraft includes a low-pressure bleed tap configured to bleed a low-pressure compressed air from a low-pressure source; a high-pressure bleed tap configured to bleed a high-pressure compressed air from a high-pressure source; an upstream duct configured to receive one or both of the low-pressure compressed air and the high-pressure compressed air; a downstream duct configured to provide a regulated compressed air to the pneumatic system; a high-pressure shutoff valve positioned between the high-pressure bleed tap and the upstream duct; a low-pressure non-return valve positioned between the low-pressure bleed tap and the upstream duct; a pressure regulating and shutoff valve positioned between the upstream duct and the downstream duct, the pressure regulating and shutoff valve configured to generate the regulated compressed air; and a pressure relief valve positioned within the upstream duct.
