This Defense Intelligence Reference Document, prepared by the Defense Intelligence Agency and dated 8 March 2010, was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It gives a historical and technical review of how to reach space and return. It covers hypersonic gliders, air-breathing and rocket propulsion, thermodynamics and materials, and launch options. It argues that reliable, schedulable access to low Earth orbit is mainly a hardware and propulsion problem rather than a technology one.

Lifting body configuration eliminates thin wings with wing-like lift High lift-to-drag ratio and global glide range Flat pane TPS system Trapezoidal cross section increases lift-to-drag ratio and reduces side and upper surface heating by 1/3 AFFDL-7C/D Lifting Body Configuration Concept All-flying control surfaces provide stability and control from Mach 0.2 to 22 Anhedral fixed fins with trailing edge flaps assure subsonic lateral-directional stability and control Figure 10. FDL-7C/D and FDL-7MC Lifting-Body Configuration. Offers inherent stability and control with sufficient volume and high lift-to-drag ratio. The switchblade wing version of the FDL-7MC was the preferred version for 1983 studies that were part of the McDonnell Douglas TAV (transatmospheric vehicle) effort; that vehicle was powered by either an Aerojet Sacramento air turboramjet or an air- breathing rocket propulsion system. The inward-turning, variable-capture area inlet 10 provides the correct engine airflow from landing speeds to mach 5.5, as illustrated in Figure 11. ~--------------- Figure 11. FDL-7C/D with a DuPont Retractable Inward-Turning Inlet The propellant tanks were cylindrical-segment, multilobe structures with bulkheads and stringers to support the flat, metal-radiative thermal-protection shingles (very similar to those fabricated by Goodrich Aerospace for the now-defunct X-33).
