Investigation on Longitudinal Optimum Location of Nacelles and Pylons on Transport Aircraft
To resolve the problem of the interference between the wing/body/pylon/nacelle of the large transport aircrafts, this paper uses the Euler equation with the Cartesian grid andfinite volume method to calculate the flow characteristic of the aircraft with different amount of protrusion and subsidence of the nacelle and pylon, then analyzes and compares the aerodynamic performance. The optimized position is selected and demonstrated. The numerical result shows that the aerodynamic performance of the transportation aircraft is obviously improved for the new optimized position of the nacelle and pylon.
