Mechanics of very long tethered systems

Analytical mechanics of asteroid disassembly using the Orbital Siphon effect

“…The tether is in equilibrium by the balance of centripetal and gravitational forces acting on it; the payload is then lifted to the desired altitude along the tether and, if synchronous orbit is reached, the payload could increase its altitude without further work required. A wide range of studies are available in the literature, investigating design, materials, tether oscillation and stability [10][11][12][13][14][15][16][17], mainly for Earth applications.…”

Auf(zug) zu den Sternen

“…Doch nicht nur das Gewicht des Kabels ist ein Problem. Ist das Kabel einmal gespannt, kann es vor allem durch die Bewegung der Kabinen wie die Seite einer Geige in Schwingungen geraten 7. Zudem wirken wie auf jeden Satelliten auch die Schwerkraft der Sonne und des Mondes auf das Kabel und können es in Schwingungen versetzen 5,8…”

Three dimensional dynamics of a flexible Motorised Momentum Exchange Tether

“…The dumbbell tether model has also been used in the recent study of tether control by Iñarrea et al [10] on the stabilisation of an electrodynamics tether in an elliptic inclined orbit. A three mass-tethered satellite model consisting of two end bodies and a climber was used in [11] and [12]. In the study of a multi-tethered satellite formation system Cai et al [13] used a massless tether connected together with point masses, and Razzaghi et al [14] modelled the system as three masses connected by a straight, uniform and inelastic tether with the inclusion of the J2 perturbation and aerodynamic drag.…”
