CHALLENGES IN GEOMETRY DEVELOPMENT FOR THE CRM-HL ECOSYSTEM
A.M. Clark¹, D.S. Lacy¹; ¹Boeing Commercial Airplanes, United States
In 2016, the High-Lift Common Research model (CRM-HL) was developed by Boeing and made publicly available to support efforts at NASA to develop advanced aerodynamic technologies. Since then, further development has occurred to define configurations of interest, including takeoff, landing, and small perturbations to challenge CFD validation exercises. These development efforts have launched a robust Ecosystem, with its foundations built on several experimental models of different scales developed by various partners around the world. Ensuring that the physical models developed are a faithful representative of the reference CRM-HL configurations presents unique challenges. Additionally, accurate and robust CFD simulation to match the physical experiments also requires specific focus. This paper will discuss the geometric considerations for consistent development and experimental testing of the CRM-HL configurations, as well as highlight requirements for CFD modeling across the CRM-HL Ecosystem.
