Bin gerade im Zusammenhang mit Gravity Assist Manövern auf folgenden nunmehr bald sechzig Jahre alten Artikel von Freeman Dyson gestoßen:
Gravitational Machines
Darin betrachtet er den ultimativen Gravity Assist oder Slingshot Effekt, den man theoretisch an einem Paar Weißer Zwerge oder gar Neutronensterne erzielen könnte.
Centauri Dreams - Pondering the ‘Dyson Slingshot’
Dyson’s considers the question in terms of binary stars, specifically white dwarfs, but goes on to address even denser concentrations of matter in neutron stars. Now we’re talking about a kind of gravitational assist that has serious interstellar potential. A spacecraft could be sent into a neutron star binary system for a close pass around one of the stars, to be ejected from the system at high velocity. If 3,000 kilometers per second appears possible with a white dwarf binary, fully 81,000 kilometers per second could occur - 0.27 c - with a neutron star binary.
