46.027 DR Terrier-Improved Malemute sounding rocket was launched from Wallops Island, VA on March 21, 2022. BOLT-2 investigated boundary layer transition, turbulent heating, and drag at hypersonic conditions. Boundary layer transition to turbulence is the process where smooth, laminar flow becomes unstable after which turbulence dominates and significantly increases heating and drag on high-speed vehicles.
