The revolutionary impact of evolving aeronautical technologies

Recent advances in aeronautical technologies which could produce revolutionary changes in transport aircraft if fully implemented are delineated. Laminar flow control offers a L/D improvement from the current 18 to 22 if used with a 767 configuration. Higher aspect and thickness/chord ratios could yield more efficient structural designs and further drag reduction. High-strength, fiber-reinforced composite structures can reduce structural weight by 10-30 percent. Improved engine cooling methods, higher stage loadings and exhaust temperatures can lower the SFC by 15 percent, engine weight by 15 percent, and the parts count by 50 percent. Aft-mounted counterrotating propellers can potentially decrease the SFC an additional 15-20 percent. Supersonic transport aircraft with L/D ratios of 18 and 70 seat miles/gal fuel efficiency can now be built that weigh half as much as the Concorde and carry the same load. The new SST would have superplastic-molded Al alloy structures.

A view of the future - Constraints and opportunities

Social and economic trends which could affect the growth of aviation in the next thirty years are examined. The possible effect of these trends together with the effects of national policies, environmental concerns, possible and probable technological advancements and the world energy problem on the developments in conventional subsonic passenger transports, long-range, high-speed aircraft, short haul operations, and air cargo transport are discussed. Passenger volume predictions from different sources are presented and contrasted, and the efficiency of turboprops and turbofans is compared.

Air transportation beyond the 1980's

An oral preview of the air transportation sections of the NASA Outlook for Aeronautics study report is presented. Now published, the study report covers military as well as civil aviation and also discusses the role of NASA in support of future developments. The study is based largely on inputs from industry, universities, and other government agencies.

Air transportation beyond the 1980's

This work is a preview of the air transportation sections of the NASA 'Outlook for Aeronautics' study report (1976). Attention is given to future directions and opportunities for civil aviation taking account of economic and demographic factors, and resources. Technical objectives for the period 1976-1985 are summarized with consideration of research in the low-speed, high-speed, and long-range flight regimes.

NASA propulsive lift STOL technology program

A NASA propulsive-lift technology program for short takeoff aircraft is discussed. In the propulsive-lift program, turbofan engine power is used to augment the lift of essentially conventional wings. Potentially important applications of the propulsive lift developments for various aircraft operating conditions are reported. It is stated that the objective of the program is to provide technical information on the design, development, operation, and regulation of propulsive-lift aircraft.
