Notes:
This paper discusses the cost of high technology and its benefits to commercial air transportation. The manufacturer's dilemma today is that, while one could pay a 16 percent price premium to obtain a 10 percent reduction in fuel cost in the late 1970s, in 1985 that price premium has diminished to only 2-1/2 percent to achieve a 10 percent fuel saving. Consequently, we must obtain the benefits of high technology at an extremely low cost. Four areas are discussed in some depth: Aerodynamics, including the effects of computational fluid dynamics, wing design, and laminar flow; structures, including the effects of new materials, both metallic and nonmetallic, and the automated tools necessary to build the nonmetallic structure; avionics, including both fly-by-wire and fly-by-light, and the improvements due to high-speed digital computers as well as flat panel flight deck displays; and propulsion systems, including the effects of high-bypass ratio, high-pressure ratio turbofan engines, and single and counter rotation turbopropellers. The final result is an integration of these four areas of technology into a composition transport aircraft and the resulting performance.
