Admission information

Objectives

of the higher and current topics of orbit and flight mechanics. After completion of the course, they have all the necessary knowledge to be able to familiarize themselves with corresponding areas and to make their own technical contributions.

Description

- Orbit geometry: coordinate systems, ground tracks, earth coverage, orbit determination, radial orbits - Orbital transitions: elementary maneuvers, general orbital transitions, Lambert transfer, Hohmann transfer (repetition), bi-elliptic transfer, continuous thrust transfer - Orbital rendezvous: Hill equations, types of relative motion, rendezvous& docking using the ISS as an example - Satellite dynamics: physics of rotation, attitude kinematics, attitude dynamics, gravitational gradient stabilization - Orbit perturbations: Gravitational perturbations, drag, radiation pressure, resonant orbits, GPS, GEO, lunisolar perturbations. - Three-body problem: synchronous orbits, R3BP, CR3BP, invariant manifolds, orbits around libration points - Interplanetary flights: patched conics, departure and approach trajectories, transition trajectories, flyby maneuvers, weak stability boundary transfers - Ascent Mechanics: Earth's atmosphere, derivation of equations of motion, ascent phases, ascent optimization. - Reentry: equations of motion, deorbit phase, ballistic reentry, reentry with lift, reflections and skip reentry, lifting reentry
