Flutter of Cantilevered Column Under Rocket Thrust
TLDR
In this paper, the authors describe an experimental investigation on the flutter of viscoelastic cantilevers subjected to a tangential follower force. But their results were compared with theoretical flutter predictions made by accounting for an internal damping of the test columns, as well as the mass and size of the installed rocket motor.Abstract:
This paper describes an experimental investigation on the flutter of viscoelastic cantilevers subjected to a tangential follower force. The force was produced by the direct installation of a real solid rocket motor to the tip end of the cantilevered columns. The columns lost their stability by flutter. The results were compared with theoretical flutter predictions made by accounting for an internal damping of the test columns, as well as the mass and size of the installed rocket motor. The introduction of the concept of instability in a finite time interval is of vital importance in predicting the experimental flutter force.read more

Dynamic stability of columns subjected to follower loads : A survey
TL;DR: A survey of simple, flexible structural elements subjected to non-conservative follower loads, such as those caused by the thrust of rocket and jet engines, and by dry friction in automotive disk-and drum-brake systems, is presented in this paper.

Experimental evidence of flutter and divergence instabilities induced by dry friction
Davide Bigoni,Giovanni Noselli +1 more
TL;DR: In this paper, a follower force of tangential type can be realized via Coulomb friction and this, in full agreement with the theory, can induce a blowing-up vibrational motion of increasing amplitude (flutter) or an exponentially growing motion (divergence).

The Kinetic Stability of a Tangentially Loaded Strut
TL;DR: An experimental method for applying a tangential force to the end of a column is described in this paper, where the force is obtained by jet reaction from a nozzle clamped to a column and free to move between parallel plane air bearings in the plane of least column stiffness.
