The fuel consumed by U. S. commercial aviation has tripled in the past decade, primarily because of the growing use of jet aircraft with greatly improved comfort, speed, cost, and reliability as compared to earlier aircraft. Although future fuels usage is uncertain, conservative projections indicate more than doubling of the fuel required for air transportation by the year 2000. NASA formed an advisory board of representatives from industry, the airlines, other government agencies, and universities. The advisory board worked with the task force to develop a technical program plan covering those technology advances with the greatest potential for saving fuel in future air transport. The final plan was submitted to the Senate Committee on Aeronautical and Space Sciences in September 1975. The result of that planning activity was the formulation of a ten-year, multiphased program plan for the aggressive development of technology for more energy-efficient transport aircraft. Now known as the NASA Aircraft Energy Efficiency Program, six major technology programs were defined that could result in fuel savings in U. S. commercial aviation. These programs are: Propulsion -- engine component improvement, energy efficient engine, and advanced turboprops. Aerodynamics -- energy efficient transport, and laminar flow control. Structures -- composite primary structures. This paper describes some recent results and presents NASA's plans for implementing these six programs.
