Bending-torsional oscillations for large aspect ratio wings are considered taking into account transversal shears, shell angle of taper as well as engines installed on elastic pylons. A boundary problem for harmonic oscillations described with ordinary differential equations and boundary conditions caused by concentrated reactions from the elastic pylons with attached engines is solved numerically reducing it to the Cauchy initial value problem for ordinary differential equations.
