Investigation of Aileron Hinge Moment of National Transport Aircraft Basic to Numeric Method

Analysis has been done of aileron hinge moment on the aircraft National Transport with numerical
methods in 2 Dimension. The analysis was performed to obtain a hinge moment magnitude resulting from the
aileron deflections and as input to the flight control team to estimate how much force must be issued by the pilot
for deflecting the ailerons to be used to fit the needs. Analysis was performed on four aileron deflection are
considered the condition of aileron deflection maximum of 20 degree, -20 degree, 10 degree and -10 degree also
analyzed the condition without deflection as a comparison to see the changes. The calculation is performed using
numerical methods in 2 Dimension using FLUENT software. From the simulation results , the magnitude of the
predictions obtained aileron hinge moment on the National Transport plane at 224.97 lb with the magnitude of the
gearing ratio is 2.75 rad/m. The force generated is still too big from 67 lb based regulation FAR 23, hence the need
for the addition of servo tabs and settings gearing ratio to reduce the force
