To study the effect of rocket mass and an intermediate mass on the critical flutter load of a free-free beam (missile-like structure).

    Design/methodology/approach

    A finite element model of beam considering shear deformation and rotary inertia, based on Hamilton's principle applied to non-conservative system.

    Findings

    Smaller geometric dimensions of the end rocket assist in the stability. Optimum positioning of the intermediate mass leads to stability.

    Practical implications

    The stability of free-free missile structures can be better understood.

    Originality/value

    Sheds new light on the effect of rocket mass and an intermediate mass on the critical flutter load of a free-free beam.
