Summary In this paper we present numerical simulation results for a generic helicopter configuration in slow descent flight. The well known HART-II test case has been chosen as the experimental reference, especially the baseline case. This test case is characterized by the occurrence of Blade-Vortex Interactions (BVI) and can thus be considered as very ambitious with respect to the aerodynamic simulation...
We present different aspects of the molecular beam epitaxy (MBE) growth of InAs QDs directly on silicon. At a substrate temperature of 370°C and a growth rate of 0.25 ML/s we observe an abrupt transition from 2D to 3D growth mode after the deposition of nominally 1.7 ML of InAs, independent of the III/V flux ratio. The density of quantum dots, measured ex situ by atomic force microscopy (AFM), depends...
