Summary
Expressions are presented which are applicable to the determination of unsteady temperature distributions in rotating space vehicles heated by solar radiation, under the assumption that surface heating rates are expressible by linearized boundary conditions. As an application, the unsteady heating of a solid circular cylinder of finite length and rotating about its geometrical axis is studied in detail and two alternate solutions are derived. Various special cases are considered and numerical results are included.
Zusammenfassung
Ausdrücke zur Bestimmung der instationären Temperaturverteilung in rotierenden, durch die Sonnenstrahlung erwärmten Raumfahrzeugen werden angegeben unter der Annahme, daß die Aufheizgeschwindigkeit an der Oberfläche durch linearisierte Randbedingungen ausdrückbar ist. Als Anwendung wird der volle Kreiszylinder endlicher Länge behandelt, der um seine geometrische Achse rotiert. Zwei Lösungen werden hergeleitet. Verschiedene Sonderfälle werden betrachtet, und numerische Resultate werden angegeben.
