Developments in Engine‐Airframe Integration

THE way in which powerplant characteristics are matched to those of an aircraft and the degree to which such integration is desirable are topics which have occupied designers for a considerable time. Development technologies influence these considerations and lead to a limited choice of powerplant locations. A recent Royal Aeronautical Society conference addressed these issues and made an introductory point of the fact that the ideal extent of integration for say, a subsonic transport, will be quite different to that appropriate to a V/STOL or stealth combat type.
