Results are given of several analytical studies of nacelles suitable for advanced subsonic commercial transport aircraft. The impact on the nacelle of reduced aircraft noise and increased cruise Mach number is emphasized and initially developed in terms of the individual nacelle components: inlet, fan cowl, nozzle, etc. This is achieved by relating the noise and cruise speed constraints to which the aircraft system must be designed to specific limitations on the individual nacelle components. Performance assessments are then made (separately for each nacelle component) of competitive design concepts. Overall nacelle designs, synthesized on the basis of the individual component studies, are briefly discussed.
