Bleed-Air Pneumatic Systems for Gas Turbine Equipped Marine and Amphibious Craft
This Information Report provides a description of bleed-air pneumatic system elements and identifies parameters required to define the requirements for a detailed specification. Specific design requirements are dependent on the application and should be incorporated in a detailed specification.
Revised to complete document conversion from (Aerospace) Hydrospace Information Report HIR 1559 to Surface Vehicle Information Report SAE J1775; References were updated, Section 2.2 was added for related (but not directly cited) references, Section 3.1 was updated to add reliability improvements using PLC controlled air valves. Section 3.4.1 was updated to add reference to SAE J1781 to replace listing of nitrogen strengthened and precipitation hardened alloys, and to suggest consideration of heat pipe (tube) materials to reduce scaling in salt water cooling. Section 3.5 was updated to add reference MIL-STD-1472 for guidelines for maximum effective environmental temperature in manned spaces.
