Abstract
A Mach-scaled model rotor with active twist capability is in preparation for a wind tunnel test in the large lowspeed facility (LLF) of the German-Dutch wind tunnel (DNW) with international participation by DLR, US Army,
NASA, ONERA, KARI, Konkuk University, JAXA, Glasgow University and DNW. To get the maximum benefit
from the test and the most valuable data within the available test time, the tentative test matrix was covered
by predictions of the partners, active twist benefits were evaluated, and support was provided to the test team
to focus on the key operational conditions
