Some quotes of key industrial partners of joint research efforts
Dr. B. Tester (principal and key research scientist Rolls-Royce, early retirement and still active in the
field, current ISVR, Visiting professor of Imperial College London, joint fan noise related work
during a 1½ decennium):
“It has been a great privilege to work with you guys at NLR and lots of fun as well.”
N. Baker (Rolls-Royce engineering) about innovative research on exhaust liners in the hot stream
acoustic liner test facility (2003):
“Thanks for your report - It is a very thorough and extensive record – and should provide a very
useful basis for further understanding of the database”
Dr. Andreas Venskutonis and Dr. Jörg Färber (PLANSEE Aktiengesellschaft, Austria) about the
advice and test of the titanium liner and other liners:
“Let us take the opportunity to say thank you for all the work you did within the WP 1.3 and also let
us congratulate to the outstanding scientific work you arranged in the course of this SILENCE(R)
sub-task. We hope that there will be another opportunities to work together on advanced noise
suppression technologies for future aircraft engine systems. We would be pleased to be at your

disposal at any time.”
List of references
On request and after consult I can give you a list of colleagues and references within the aeroacoustics
aerospace and gas turbine community (research establishments, universities and industry), where you
can inform about my former work and their assessment of it (quality, work efficiency, relevancy for
the field and “social quality”).
