Please help me understand why RR designs longer nacelles then GE and PW. It is evident on the A330 but also on other implementations. Here the 330 with in order RR T700, GE CF6 and PW4000:
The longer nacelle is not limited to RR 3-shaft engines, their influence is also evident in the IAE V2500 nacelle. What does one gain with a longer nacelle vs a shorter one?
