Abstract. The article examines the flutter behavior of finite-length conical shells. Conical shells are widely used as components in aviation engineering, making the analysis of their oscillations essential for ensuring safety and stability. The paper presents a modern non-saturation numerical algorithm and derives an approximate formula for the critical flutter speed of a conical shell, enabling the avoidance of complex calculations in practical studies of rocket engine nozzles. Specific calculations are provided for four materials: titanium, steel, aluminum, and duralumin, demonstrating the method’s high efficiency. A general interpolation formula is developed, which satisfies the boundary conditions at the free edge.

Keywords: conical shell, eigenvalue problem, non-saturation numerical algorithm
