Abstract
Purpose
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.
