    Abstract

    A detailed analysis of the aeroelastic characteristics13; of HANSA2 has been carried out by using three different13; methodologies. All the lifting surfaces of the aircraft13; viz., wing,horizontal tail and fin, are of a large aspect ratio. Hence they can be adequately represented by a typical section, at 75%. of the semispan, for the purpose of calculation of the critical speeds and frequencies.These calculations have been further sub startiated by those based on the CAA charts and finite element analysis. The balancing masses used on the three control surfaces viz., aileron, elevator and rudder have been checked for both static and dynamic balancing by the use of CAA charts. The calculations indicate adequate margins for both flutter and divergence speeds
