VKI-LS In aero-engine as well as industrial gas turbines, the drive to higher efficiency is steadily raising the pressures and temperatures in the engines, and this further increases the challenge to instrumentation. Accurate measurements in the hot components of gas turbines (including combustion diagnostics) are recognized as a major need for the assessment of engine component health and performance. High temperature instrumentation is required not only during product development for the validation of new designs or component life prediction methods, but also in service for health monitoring and optimum engine control. After some introductory basics on measurement chains, errors and uncertainties, this course will therefore address the following topics: measurements of surface temperatures, measurements of gas path pressures and temperatures including steady and unsteady measurement techniques, measurements of blade tip clearance and blade vibration (tip timing and strain gauges) at high temperatures.

The Lecture Series directors is Prof. J-F. Brouckaert of the von Karman Institute for Fluid Dynamics, Belgium.

FEE

The fee for the lecture series is 1300 euro, applicable to citizens of NATO countries contributing to the financing of the VKI (Belgium, Czech Republic, France, Germany, Hungary, Iceland, Italy, Luxemburg, Norway, Portugal, Spain and Turkey). For citizens of other NATO countries and of NATO partner countries, the fee is 1700 euro. For non-NATO citizens the fee is of 1850 euro. These prices include 21% VAT.

To encourage greater participation in our Lecture Series programme by university members, the Institute has established a limited number of VKI Lecture Series fellowships for citizens of NATO countries contributing to the financing of the VKI, as well as for citizens of other NATO countries coming from a university in a VKI financing country. The recipient of such fellowship is entitled to attend the Lecture Series at a reduced fee, which will be of 650 euro (VAT included) for assistants not having a Ph.D. degree and for Ph.D. candidates, or 300 euro (VAT included) for undergraduate students. The request to be considered for an award must accompany the application to attend the Lecture Series, and the applicant must provide a recommendation letter from his or her professor; if not done so, the request will not be taken into consideration. All possible alternative sources of funding should be investigated before aid is requested under this scheme, so that those most in need will benefit.
