Figure 2 shows that the United States is losing market share in terms of unit orders in the important category of large commercial transport aircraft to Europe, down from 73 percent in 1990 to 54 percent in 1998.~ 2 The demand for smaller regional commercial jet transport aircraft is growing, but the two major suppliers of regional jets, Bombardier and Embraer, are based in foreign countries (Canada and Brazil, respectively)

NASA's low-drag cowl for radial engines and "coke-bottle fuselage" to reduce transonic drag rise are examples from the past. In the Department of Defense, more recent aeronautics breakthroughs include shaping for stealth; multi-axis thrust vectoring exhaust nozzles integrated with aircraft flight-control systems; fly-by-wire flight control technologies; high-strength, highstiffness fiber composite structures; and tilt-wing rotorcraft technology.

Secondary benefits are also accrued. For example, investments in air traffic control systems worldwide are expected to range from $41 to $58 billion.9 Also, the technology to develop efficient gas turbine engines has been used to develop gas turbine engines for other uses, such as ship propulsion and emergency electrical generation in critical buildings.

market share for commercial jet transport aircraft, recent regional conflicts, and the Air Force's decision to devote more of its assets to space developments and operations in an era of declining overall budgets have made the needs for strong support for aeronautics R&T more urgent. The committee agrees with the conclusion reached by other studies that govenunent finding of aeronautics R&T is worthwhile.

We must now renew our focus on partnership to meet national challenges and accomplish national goals."'4 The committee recommends that major improvements be made in the coordination of aeronautics R&T activities among NASA, the Department of Defense, the Federal Aviation Administration, industry, and academia. An overarching organization for national aeronautics R&T is needed to speak for national values, ensure efficient use of resources, make cooperative actions more productive, and eliminate duplication where it is not an effective motivator of competition.

BOX 1 NASA's Aeronautics Goals In March 1997, NASA's Office of Aeronautics and Space Transportation Technology adopted 10 enabling technology goals to guide pre-competitive research in long-term, high-risk, high-payoff technologies. The goals are in three groups or~pillars": Global Civil Aviation · reducing the aircraft accident rate reducing emissions reducing perceived noise levels increasing aviation system throughput reducing the cost of air travel · Revolutionary Technology Leaps reducing travel time to the Far East and Europe invigorating the general aviation industry developing advanced design tools and experimental aircraft · Access to Space reducing the cost of launching payloads to low-Earth orbit by an order of magnitude by 2007 reducing the cost of launching payloads to low-Earth orbit by another order of magnitude by 2020 Source: Aeronautics and Space Transportation Technology: Three Pillars for Success, NASA Office of Aeronautics and Space Transportation Technology, Washington, D.C., March 1997.
