Advanced heavy lift launch vehicles

The performance requirements of advanced technology-incorporating, next-generation heavy lift launch vehicles (HLLVs) for LEO missions are discussed, and the configurational features facilitated by those technologies are evaluated. These 1990s 'cargo' vehicles will capitalize on advanced avionics, software and automation, novel hot structure and thermal insulation materials, and more powerful liquid-fuel rockets employing either hydrogen or hydrocarbons. The configurations considered include a winged booster. The use of Space Shuttle components is a major cost-minimization strategy in many of these HLLV design efforts.
