- What is the difference between a nacelle and a cowling?
8 Nacelle comes from the french word "nacelle" which is the gondola or wicker basket suspended beneath a balloon So, by analogy, many things that are outside the body of an aircraft, like the compartments that house the engines, can be called nacelles A cowling is the covering of a vehicle's engine even if that motor is not inside a nacelle
- noise - Why does the Boeing 787 engine nacelle exhaust have such an . . .
Why does the Boeing 787 nacelle have this unique shape at the exhaust: I haven't seen it on any other airplanes, does it serve an aerodynamic purpose or help engine efficiency or is it just to look pretty?
- What is this flange on the engine? - Aviation Stack Exchange
The vortices mix the nacelle boundary layer air with the free stream and reduce the momentum loss in the wake The vortices then pass just over the upper surface of the wing, continuing this mixing process The counterrotating vortices also create a downwash over the wing region unprotected by the slat, further reducing the premature stall
- aircraft design - Why are the Boeing 737 nacelles odd shaped . . .
The fan diameter was reduced, which reduced the bypass ratio, and the engine accessory gearbox was moved from the bottom of the engine (the 6 o'clock position) to the 9 o'clock position, giving the engine nacelle its distinctive flat-bottomed shape
- aerodynamics - Why dont all aircraft use need nacelle chines . . .
The chines help when the nacelle is very close to the wing When the engine of Boeing's 737 was changed from the slim JT-8D to the higher bypass ratio CFM-56 on the 737-300 and later, the chines were essential to avoid large flow separation Generally, aircraft with higher landing gear can afford to have more space between nacelle and wing and do not need fixes like chines But when a new

I seem to have some give to the grip, like a small amount or twist each way, almost mechanical
- What is this phenomenon where a narrow stream of airflow off a nacelle . . .
The vortices mix the nacelle boundary layer air with the free stream and reduce the momentum loss in the wake The vortices then pass just over the upper surface of the wing, continuing this mixing process The counterrotating vortices also create a downwash over the wing region unprotected by the slat, further reducing the premature stall
