Abstract

The NASA Environmentally Responsible Aviation (ERA) Project was established in 2009 with the purpose of developing and analyzing vehicle concepts and technologies aiming at reducing the impact caused by modern aviation to the environment. Virginia Tech’s role in this project was to develop a novel means to study the effects of inlet swirl distortion on turbofan engine performance and operability. The resulting tool, the StreamVaneTM, allows generation of prescribed distortion profiles in a full-scale, ground testing environment instrumented with probes and particle image velocimetry. The StreamVaneTM design is based on the analysis of the desired engine inlet velocity profile. A distortion screen consisting of non-uniform blades is created by placing vanes everywhere perpendicular to the desired velocity field. The turning vanes are then generated, and a CAD model is obtained. The model is printed using 3D printing techniques that permit versatility in the material and precision in the final model. StreamVaneTM models have been tested both at small-scale, in a 6” wind tunnel and at full-scale in a PWC JT15-D engine using Stereoscopic Particle Image Velocimetry (PIV). The results obtained exhibit that the StreamVaneTM method and instrumentation applications provide a valuable tool for generating and characterizing predetermined swirl distortion profiles encountered by turbofan engines for advanced concept vehicles. In this article, a perspective on StreamVaneTM performance related to ground test applications is provided.
