High Lift Common Research Model

This activity, in collaboration with Boeing, seeks to predict the dry air aerodynamics around an iced or uniced vehicle.  Computational icing tools consist of predicting two distinct problems: (1) the accretion of ice due to flight in icing conditions and (2) the dry air aerodynamics around the iced or uniced vehicle. A desire exists to advance these tools such that they can be reliably used earlier in the design process to limit the need for more costly flight and wind tunnel testing. To achieve these goals, the computational tools need to be benchmarked and validated against high quality experimental data sets to raise the software’s Technology Readiness Level. This effort is gathering experimental data to benchmark and ultimately validate the tools that predict the aerodynamics around the iced and uniced vehicle. Currently the scope of this effort is focused on the usage of simulated ice shapes to be representative of the iced vehicle.
