More Book Details

Description of the Book:

An analytic solution to the optimal low thrust problem is developed using a first-order perturbation approach for planar orbit transfers. This solution is verified by comparison with the solution obtained by integrating the equations of motion. For low vehicle accelerations the analytic solution yields results quite close to those obtained by the integrated solution. At higher acceleration levels, however, the analytic solution diverges from the integrated solution. For very low acceleration levels the analytic solution approachs the limiting case of the infinitesimally low thrust spiral solution. Keywords include: Low thrust; Orbit transfer; Perturbation; Optimization
