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.
