System Integration as Key for Improving and Speeding up the Preliminary Design Phase of Aero Engines

A design change from bladed disk to blisk leads to stronger endurance limits. The paper deals with aerofoil adaption of a blisk within a multi-criterion optimisation loop. Blisks are more sensitive to external excitation since mechanical damping is very low. Thus stronger limits have to be applied which are hard to be fulfilled and hence it requires the use of numerical optimisation. Combination of 2D CFD and FEM in a common optimisation loop to re-design a given blisk. Determination of relevant features for improving blisk endurance. Modern process integration and multi-criterion optimisation tools in combination with today's increased computational power allow to perform mulitphysics design even in the case of complex industrial design tasks.

Planetary gearboxes in highly sophisticated applications such as turbofan engines are required to have a high power-to-weight ratio and excellent reliability. Hence, thin-rimmed gear units need to be designed as compact as possible which, however, is usually limited by the tooth root load capacity. In order to come up with the best design, a tooth root shape optimization process is developed for thin-rimmed planet gears.
Zhe paper introduces ideas from shape optimization to multibody system dynamics. A disk rolling down a given slope is taken as a simple example, for which it is the goal of the optimization to shape the rolling contour of the disk such that it takes a minimum time to cover a certain distance. The shape of the sontour is described by its radius of curvature. The governing equations of motion result from the kinematics of relative motion and the Nowton-Euler formalism. Three different kinds of spirals are defined and optimized.
