Importance of stability investigations of elastic systems subjected to non-conservative forces, such as missiles, aircraft, and various elements of high-performance launch vehicles, is shown; cantilevered, continuous pipe conveying fluid at constant velocity is studied analytically; it is shown that sufficiently small velocity-dependent forces, such as internal and external damping, as well as Coriolis forces, may have destabilizing effect; it is demonstrated also that Galerkin method with two-term approximation may lead to erroneous results when velocity-dependent forces exist in system.
