Abstract:
A high-enthalpy short-duration wind tunnel (hotshot wind tunnel) is designed for different operation modes ensured by combining various methods of test gas heating [by an electric arc, chemical energy, adiabatic compression, and heating in an external source of heat (with respect to the settling chamber)]. The wind tunnel is designed for the following ranges of parameters: stagnation pressure $p_0 = 1–200$ MPa, stagnation temperature $T_0 = 600–4000$ K, Mach number $\mathrm{M} = 4–20$, and test time $t < 1$ s. The wind tunnel can operate both in the regime of the classical hotshot facility with decreasing parameters of the test gas and in the regime with stabilization of parameters owing to synchronized motion of the opposite pistons of the pressure multiplier toward each other.
Keywords:
high-enthalpy short-duration wind tunnel, hotshot wind tunnel, settling chamber, test gas, stabilization of parameters, pressure multiplier, electric arc, chemical heating, adiabatic compression.
