In 2005 the new source of inexhaustible ecological clean and powerful energy is invented. This new
converter of natural gravitational energy makes it possible, at negligible cost, to generate any commercial
quantity of ecological clean electricity without dependence on a weather and climate continuously
many years. The converter is capable of replacing heat & power and nuclear power station. This device
has been successfully tested and it is ready to introduction in industry. In ninth number of this
magazine it has been told about this invention. This article of magazine contains some basic formulas
and new experimental results.

The document analyzes the chaotic motions that can occur for tethered satellite systems with low thrust. It describes the system and assumptions, presents the motion equations, and identifies stationary solutions. Orbital eccentricity and out-of-plane oscillations are shown to induce chaos if they cause an unstable equilibrium condition. The choice of thrust level, satellite masses, and tether length must satisfy conditions to ensure regular in-plane motion even in an elliptic orbit.
The document proposes using an Autonomous Docking Module (ADM) attached to a space tug by tether to remove orbital debris. The ADM would use a probe-cone mechanism to dock with the target debris, a spent orbital stage, without its cooperation. A mathematical model is developed to simulate the docking process between the ADM and tumbling target. Further simulation and development of rendezvous scenarios and a testbed mission are recommended to validate the concept.
The document discusses nanosatellite deployers, which isolate CubeSats from the launch vehicle and main payload and deploy them into orbit. It describes several common deployer types, including the P-POD, ISI-POD, X-POD, NANORACKS, RSC-POD, and CSD. The document summarizes simulations and experiments that analyzed factors affecting CubeSats' tip-off rates after deployment, such as their mass properties, spring stroke distances, and clearances between guide rails. Ground and microgravity flight tests indicated 3U CubeSats typically have maximum rotational rates under 10°/s after deployment, while 1U CubeSats' rates
The document discusses models and experiments to analyze the tip-off rate dynamics of CubeSats during separation from deployers. A simplified model and complex ADAMS model were developed to simulate the effects of parameters like center of mass position, spring stroke, and gap between guide rails on tip-off rate. Ground experiments using laser sensors to measure angular velocities of a 3U CubeSat mock-up showed results that agreed satisfactorily with simulations. The models and experiments allow estimating tip-off rates to help design CubeSat deployers that minimize initial angular velocities.
The document describes the chaotic behavior that can occur in a system consisting of a space tug, viscoelastic tether, and space debris. A mathematical model is developed to describe the transverse and longitudinal oscillations of the tether. The model shows that chaos is possible when the longitudinal oscillations are perturbed. Poincare sections are used to reveal a stochastic layer in the system's motion due to damping in the tether. The results suggest that chaos can be observed in the attitude motion of the tethered tug-debris system caused by longitudinal oscillations of the viscoelastic tether.

The document discusses active debris removal in space using tethered towing. The authors have developed a mathematical model of the attitude motion of a debris-tether-tug system. The model accounts for factors such as flexible appendages on the debris, fuel residuals, tether properties, and environmental forces. The authors aim to further study the capture dynamics of debris and stabilization after capture, and create a comprehensive model covering all stages from initial capture to atmospheric reentry.
