NASA NTRS1995

Aviation system capacity improvements through technology

A study was conducted with the primary objective of determining the impact of technology on capacity improvements in the U.S. air transportation system and, consequently, to assess the areas where NASA's expertise and technical contributions would be the most beneficial. The outlook of the study is considered both near- and long-term (5 to 25 years). The approach was that of actively working with the Massachusetts Institute of Technology (MIT) Flight Transportation Laboratory and included interactions with 'users' outside of both agencies as well as with organizations within. This report includes an overall survey of what are believed to be the causes of the capacity problems, ongoing work with the Federal Aviation Administration (FAA) to alleviate the problems, and identifies improvements in technology that would increase capacity and reduce delays.

Future regional transport aircraft market, constraints, and technology stimuli

This report provides updated information on the current market and operating environment and identifies interlinking technical possibilities for competitive future commuter-type transport aircraft. The conclusions on the market and operating environment indicate that the regional airlines are moving toward more modern and effective fleets with greater passenger capacity and comfort, reduced noise levels, increased speed, and longer range. This direction leads to a nearly 'seamless' service and continued code-sharing agreements with the major carriers. Whereas the benefits from individual technologies may be small, the overall integration in existing and new aircraft designs can produce improvements in direct operating cost and competitiveness. Production costs are identified as being equally important as pure technical advances.

Future regional/commuter challenges

Technological advances in the next ten years will represent a continuum of the steady improving state-of-the-art in all the major disciplines. In the past there was a number of step changes in technology, but no known really large quantum jumps are envisioned at present which could be readily applied to short haul aircraft. The one exception in the field of aerodynamics might be the application of natural laminar flow on short haul and laminar flow control on long haul aircraft. The aim in the 1990's will be to single out the major areas where advances will contribute to overcome important constraints such as fuel conservation, noise, airspace and airport saturation, and surface transportation competition.
