The effects of engine mass and its location on the free vibration and flutter behaviour of two representative transport aircraft wings are investigated using an assembly of coupled bending-torsion beams and Theodorsen type unsteady aerodynamics. The aeroelastic computer program CALFUN (CALculation of Flutter speed Using Normal mode method) has been used when computing the results which are discussed and commented on
