Advanced transport aircraft technology

Various elements of the NASA aircraft energy efficiency program are described. Regarding composite structures, the development of three secondary and three medium-primary components to validate structural and fabrication technology is discussed. In laminar flow control, the design of advanced airfoils having large regions of supercritical flow with features which simplify laminarization are considered. Emphasis is placed on engine performance improvement, directed at developing advanced components to reduce fuel consumption in current production engines, and engine diagnostics aimed at identifying the sources and causes of performance deterioration in high-bypass turbofan engines. In addition, the results of propeller aerodynamic and acoustic tests have substantiated the feasibility of achieving the propeller efficiency goal of 80% and confirmed that the effect of blade sweep on reducing propeller source noise was 5-6 dB.

Overview of NASA general aviation program

The NASA efforts devoted to new technology for general aviation are summarized. Areas covered include: (1) improved safety through improved crashworthy structural design, spin resistance, and improved operations around uncontrolled airports; (2) reduced environmental impact for both reciprocating and turbine engines; and (3) research for improvement in the performance of both aerodynamic and system components.

NASA general aviation research overview - 1976

Recent accomplishments in the field of general aviation are reviewed which resulted from NASA's steadily improving communication with the industry and user community, both on a formal level and through more direct involvement in the research activities. Several NASA programs are examined whose aim is to provide new technologies across the board for improvements in safety, efficiency, and reduction of the impact of general aviation on the environment. The use of the results of some NASA programs in designing new aircraft is demonstrated. A list of technical reports generated by the NASA program is given in an appendix.

NASA general aviation technology programs

This paper describes the status of the current NASA programs that are aimed at providing new technology for aircraft designs that will improve both safety and utility while reducing the environmental impact of general aviation to acceptable levels. Safety related areas that are discussed include the full scale crash test program and the stall/spin research effort. Among the programs addressing increased utility and performance, advanced airfoil developments and engine cooling drag reduction are discussed. Noise and emission reduction is a subject that is receiving significant emphasis within the NASA programs. Also included is a description of the current status of the hydrogen injection concept as a means of both lowering emissions and increasing fuel economy.

Fundamental advancements of the future.

General aviation encompasses all aviation except air carrier and military. This includes a broad spectrum of aircraft types ranging from amateur-built aircraft to jet transports, and includes missions such as transportation of people and freight, firefighting, power line patrol, agricultural, racing, and police patrol. The time span from discovery to broad utilization is such that for the next decade the majority of the innovations that will show up in the general aviation fleet will be derived from today's research efforts. A second area that has high potential is the modification of technology developments for military and transport aircraft to the needs of general aviation requirements of cost, complexity, and reliability.
