Flutter calculations for a semispan model wing with a trailing edge control surface have been carried out using the MSC NASTRAN computer program. In order to alter the critical flutter speeds of the model wing, provision was made to allow rods or other masses to be attached at the wing tip. In these calculations aluminium and steel rods were used to modify the flutter characteristics of the model. Eleven configurations of the model wing were considered. For each of the 11 configurations, flutter calculations were carried out for a number of different aileron rotational stiffnesses.
