title = "Development of the BOLT II Roughness Experiment for Flight",
abstract = "BOLT II is a sounding rocket research project with the goal of studying hypersonic boundary layer transition and turbulence. The BOLT II research vehicle is based on a threedimensional geometry (a slightly longer version of BOLT) with concave surfaces and swept leading edges that provides two separate and distinct, also redundant, flow paths for conducting measurements. One side of BOLT II is dedicated to smooth surface transition and turbulence, to better study the natural instability processes, while the other has been assigned to study forced transition and turbulence using discrete roughness trips. The present paper is intended to document the primary drivers and decisions made leading up to finalizing the roughness side experiment for the BOLT II flight.",

note = "Funding Information: NASA{\textquoteright}s contribution to the BOLT and BOLT II projects comes from the Hypersonic Technologies Project, Advanced Air Vehicles Program, Aeronautics Research Mission Directorate. The DoD HPCMP Hypersonic Vehicle Simulation Institute provided support to the USAFA to conduct the wind tunnel testing. The computational work on the BOLT and BOLT-II geometries is supported by AFRL/AFOSR under grant numbers FA9550-18-1-0010 and FA9550-19-1-0154, respectively, with program officers Drs. Ivett Leyva and Sarah Popkin. The authors are grateful to Pointwise and NASA for providing the Pointwise meshing program and the DPLR CFD code, respectively. The authors also acknowledge the Texas Advanced Computing Center (TACC) at The University of Texas at Austin for providing high performance computing (HPC) and storage resources that have contributed to the research results reported within this paper. In addition, portions of this research were conducted with the advanced computing resources provided by Texas A&M High Performance Research Computing. CUBRC{\textquoteright}s support comes from the same two grants mentioned above. Support to the University of Arizona was provided by AFOSR, with Sarah Popkin as the Program Manger. The authors would also like to thank Bryan Morreale and Rodney Bowersox for providing the US3D solutions to support the computational analysis and Christoph Hader for CFD roughness calculations.
