TECHNOLOGIES FOR THE AIR TRANSPORT OF TOMORROW

A review of technologies essential to the future cost effective development and implementation of large transport aircraft is presented. Emphasis is placed upon the importance of improved methods of design optimization and qualification testing, including ground and flight simulation techniques. Progress in optimization of lift-drag ratios through reduction of transonic drag, skin friction drag, induced drag, wave drag, and casing/motor interference drag is discussed. The task of developing turbofan engines to meet requirements for economical operation while minimizing noise by use of acoustic insulation and appropriate flight procedures is described. The application of new construction techniques and the use of composites to reduce construction and maintenance costs are considered, together with advancements in systems integration and avionics.
