    Description / Table of Contents: Zusammenfassung Das Ziel der vorliegenden Arbeit ist die Erforschung des Einflusses der normalen und seitlichen Wärmeleitung auf die Temperaturverteilung und den Wärmeübergangskoeffizienten auf der Oberfläche einer typischen Überschallrakete. Dazu wird mit der Methode der Finiten Elemente eine zweidimensionale Wärmeleitungsgleichung mit einer zeitabhängigen Zufuhr von Reibungswärme durch die Luftströmung an einer Wand und Stahlungswärmeaustausch an der anderen Seite als Randbedingung gelöst.
    Notes: Abstract The main purpose of the present work is to investigate the influence of normal and lateral conduction on the temperature distribution and heat transfer coefficient on the surface of a typical sounding rocket. A two-dimensional heat conduction equation with a time dependent aerodynamic heating condition at one surface and a radiation boundary condition at the other end is solved using finite element method.

    Notes: A numerical solution of the nonlinear inverse heat conduction problem is obtained using an in-line method in conjuction with the measured thermocouple temperature history. The deforming finite elements technique is used to treat initial time delay in temperature response due to thermocouple location. In the absence of elements deformation, the method reduces to the conventional Galerkin formulation. A three-time level implicit scheme, which is unconditionally stable and convergent, is employed for the numerical solution. The temperature-dependent thermophysical properties in the resulting matrices are evaluated at the intermediate level. The complication of solving a set of nonlinear algebraic equations at each step is avoided. Illustration of the technique is made on the one-dimensional problem with a thermal radiation boundary condition. The results demonstrate that the method is remarkable in its stability to predict surface condition without debilitation.
