✦ Synopsis

Stability requirements for flexible satellites are found to include the well-known rigidbody stability criteria, and, in addition, requirements on the elastic and coupled rigidelastic motion.

Summary--Utilizing a method for the stability analysis of coupled rigid-elastic systems, the effect of flexible antennas upon the stability of motion of a gravity-gradient satellite is investigated. The satellite is assumed to consist of a compact rigid-body containing four antennas located at right angles to each other, two in the orbit plane and two perpendicular to the orbit plane. The conditions for stability are found to include the well-known rigid-body stability criteria, and, in addition, requirements on the elastic and coupled rigidelastic motion.

Observations have been made on spermatozoa from the domestic fowl, quail and pigeon (non-passerine birds) and also from the starling and zebra finch (passerine birds). In free motion, all these spermatozoa roll (spin) continuously about the progression axis, whether or not they are close to a plane

## Abstract This paper models the dynamics of a three‐dimensional inextensible filament, as a function of a given velocity distribution along its centreline. This geometric problem has various applications in physics, engineering and biology, e.g. the dynamics of vortex lines, the motion of bacteri
