POWERED WIND TUNNEL TESTING WITH HYDRAULIC MOTORS
D. Steiling¹, P. Aschwanden¹, J. Müller¹, T. Jax¹; ¹RUAG AG, Switzerland
The integration of propulsors in aircraft can be a challenge and often needs to be investigated in a wind tunnel test. The hydraulic technology in use at the RUAG wind tunnel for powered testing is described. Examples of actual test setups ranging from isolated propeller tests, both full-scale and model scale, to complex multi-engine aircraft models are given.
