Query: Attitude and orbit coupling of planar helio-stable solar sails   The coupled attitude and orbit dynamics of solar sails is studied. The shape
of the sail is a simplified quasi-rhombic-pyramid that provides the structure
helio-stablility properties. After adimensionalisation, the system is put in
the form of a fast-slow dynamical system where the different time scales are
explicitely related to the physical parameters of the system. The orientation
of the body frame with respect to the inertial orbit frame is a fast phase that
can be averaged out. This gives rise to a simplified formulation that only
consists of the orbit dynamics perturbed by a flat sail with fixed attitude
perpendicular to the direction of the sunlight. The results are exemplified
using numerical simulations.
