The Energy Problem—Its Effect on Aircraft Design: Part 3 Advances in Aircraft Design

There are several improvements in prospect in the design of aircraft and engines which offer benefits to the amount of fuel used. Most are based on a solid background of research, and therefore the potential gains are fairly predictable. However, it is also true that most of the advances will need considerable development work to bring them to a point of readiness for introduction in design. The advances described below are ones which might reasonably be expected to be introduced into new designs in the mid‐1980s.
