Abstract:

A new generation of fairly large aircraft with slender wing and no tail-unit is about to be produced. These aircraft have a number of new features which differ both from those of delta wing fighter aircraft and from those of transport aircraft with moderately swept back wings. Some of these unusual features are analysed from the point of view of the various tasks to be performed by the pilot and the applicability of certain standard or new criteria is examined. Possible characteristics of lateral stability are fairly widely explored and the complexity of the problem and the interaction between the various criteria are illustrated. When discussing longitudinal stability emphasis is placed on the particularly typical case of the behaviour of the aircraft at low speeds. The conclusion is drawn that for these aircraft the critical points are different from those of their predecessors and that the standards for assessing them must quite often be re-considered. Their stability and control characteristics as a whole, however, although different, compare favourably with those of preceding generations of aircraft. Author
