NASA CONTRIBUTIONS TO THE HIGH LIFT COMMON RESEARCH MODEL ECOSYSTEM

M. Rivers, United States

As part of the High Lift Common Research Model (CRM-HL) ecosystem, NASA has designed and builtrntwo CRM-HL models. The first model is a 5.2% scale semispan model that has been tested in the NASArnLangley 14- by 22-Foot Subsonic Wind Tunnel (14x22), the low-speed wind tunnel DNW-NWB in Germanyrnand in the National Transonic Facility (NTF) at NASA Langley Research Center. Information on the NASArntests that will include wind tunnel information, model details, test methods and some test data will bernpresented in the final document. The second model is a 2.7% scale model that will also be tested in the NTFrnin both full span and semispan configurations. Information on the design and fabrication of this model willrnbe included in the final document.rnThere will be a total of four tests of these two models in the NTF. The first 5.2% semispan test focused onrnforce and moment and surface pressure measurements to compare with other data obtained for thernecosystem and to provide high Reynolds number data. The second 5.2% semispan test will focus on flowrnfield measurements, both on and off surface. The third test will be of the 2.7% full span model that willrnalso focus on force and moment and surface pressure measurements while the fourth test will be of thernsemispan 2.7% model that will focus on comparisons of full span versus semispan data differences. Morerninformation will be provided in the final document.rn1
