The structural, aerodynamic and acoustic design of a lined test section necessary to produce a sufficiently reflection-free environment for noise tests in the Aircraft Research Association (ARA) tunnel at Mach numbers up to 0.85 are described. The aerodynamic design was aided by computational fluid dynamics methods and the acoustic design by a ray-theory model. Results of the aerodynamic calibration of the liner and preliminary acoustic and performance tests on two model propellers are presented. Development work carried out to improve the liner acoustically and aerodynamically is described.
