...Paul F. Beard; Thomas Povey; Kamaljit S. Chana A turbine efficiency measurement system has been developed and installed on the turbine test facility (TTF) at QinetiQ Farnborough. The TTF is an engine-scale short-duration ( 0.5 s run time) rotating transonic facility, which can operate as either...
