Investigation Into Modeling And Control Methods To Optimize The Power Output Of Wind Turbines
… as attitude with respect to the wind and blade pitch settings. Optimizing power output with respect to these parameters is accomplished by optimizing the rotary system's power coefficient. A primary objective of this research is to optimize the power coefficient in a design space that includes …

Implementation of a trim routine in a rotor model for the numerical simulation of helicopter flow-fields
… between experimental and numerical collective pitch angle and cyclic pitch coefficients were found. Also the effect of the fuselage on the trim conditions proved to be minimal.

Analysis of the propulsion and manoeuvring characteristics of survey-style AUVs and the development of a multi-purpose AUV
… a vectored thruster and a collective and cyclic pitch propeller. The manoeuvring performance of both devices was found to be insufficient to justify the additional engineering complexity associated with them.<br/>The aim of the next generation of AUVs is to be able to combine long range …

Entwicklung eines Lebensdauersensors : Entwicklung und Anwendung eines neuartiges Konzepts zur Aufnahme von Bauteilbeanspruchungen für Betriebsfestigkeitsanalysen
… advantage of matrix evaluated data compared to cyclic pitch data based on Rainflow counting or cycle counting Algorithms, is the consideration of the shift in the mean stress. Successful testing of the data logging, measurement data pre-processing and wireless communication has been carried out …
