A 6-inch high-enthalpy impulse test facility is constructed at Korea University. Impulse facilities, including an expansion tube, are capable of reproducing a wide range of high-enthalpy gas flows. While impulse facilities are renowned for their mechanical simplicity and cost-effectiveness, they have shorter test times. The primary objective of the expansion tube is to delve into the combustion characteristics of the scramjet combustor. In order to maximize test time, each section’s dimensions were meticulously optimized based on analytical solution. Subsequently, numerical simulations were carried out to verify the calculated test durations and conditions and assess the expansion tube’s performance. The facility was then constructed in accordance with the design specifications.
