New nacelle designs show benefits of first steps to closer engine/airframe integration
Aerospace researchers generally agree that step changes in efficiency for future commercial aircraft designs will only be achieved through unprecedented levels of integration between propulsion and airframe. Despite uncertainty over exactly how this will happen, some engine and nacelle manufacturers are taking the first tentative steps. Some are pressing ahead with integrated propulsion systems (IPS), while Pratt & Whitney is developing the variable-area nozzle. Though a far cry ...
