Defense Intelligence Reference Document Materials For Advanced Aerospace Platforms

Defense Intelligence Agency · 27 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 12 January 2010, is one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications (AAWSA) program. It reviews materials for launch vehicles, space vehicles and reusable rocket engines, including aluminum alloys, polymer and metal matrix composites, titanium and nickel alloys, ceramics and titanium aluminides. It concludes that newer materials and design methods offer many ways to improve structural efficiency and cost compared with the space shuttle.

this demonstrated inspections capability. lmplementation of these standards,
starting with the B-1 bomber and the F-100 and F-110 engines, has
dramatically reduced {but not eliminated) the incidence of catastrophic
failures of critical components that endanger crews, vehicles, or both.
Taking these changes into account, this document outlines the current
situation regarding the design and production of high-performance structures
for aerospace platforms, including launch vehicles, space vehicles, and
propulsion systems for transporting space vehicles (and payloads) into orbit.
