In this paper we consider the motion of a debris objects with fuel residuals that can affect the safety of the debris transportation process.
This sudden narrowing in the cross section may had a significant effect on the motion of the debris flow as it flowed to the residential area, because of the constricted flow channel.
The new method detects these parameters in low computational time in a serial manner, which implies that it has an advantage to track not only linear but also nonlinear motion of GEO debris more easily than the previous methods.
While the inherent randomness in the debris flight trajectory is irreducible due to the wind turbulence, variation in wind direction, gustiness of the wind event, and so forth, the proposed probabilistic model seeks to address these uncertainties through Monte Carlo simulations with the appropriate statistical distributions applied to the governing equations of motion of the debris.
Compact debris are objects possessing non-negligible mass but negligible moment of inertia (e.g., a particle-type object); the wind-driven motion of the debris is predominantly controlled by aerodynamic drag with a limited influence of aerodynamic lift or moment.
Based on the orbital resonance model, we study the two-dimensional phase plane structure of the motion of space debris orbiting the geosynchronous ring under the combined effects of the tesseral harmonics J22, J31 and J33 of the Earth's gravitational field.
The equations of motion for debris flight are derived in a generalised dimensionless form that reveals the fundamental controlling parameters of the problem.
The non-principal-axis rotational motion of uniaxial space debris can be decomposed into periodic motions associated with two frequencies: the polhode frequency of the space debris rotating around the symmetry axis, and the tumbling frequency of the symmetry axis rotating around the angular momentum.
Fig. 35 Schematic showing how the motion of a space debris object, indicated by the red line, could be tracked by using multiple quasi-simultaneous beams, as will be available in EISCAT_3D (courtesy of Dr J Vierinen).
On the other hand, macroscopic gravity-driven motion of landslides and debris flows evolves over a characteristic time scale (L/g)1/2, where g is the magnitude of gravitational acceleration and L is the characteristic length of the moving mass.
