Ground testing for the atmospheric entry environment requires precise matching of key flow parameters. However, existing hypersonic facilities cannot comprehensively replicate all aspects of this complex environment. Impulse facilities can match the velocity and total pressure of hypersonic flow, but only for a short test duration. Plasma wind tunnels can generate continuous high-enthalpy flow, but challenges arise in achieving aerodynamic similarity. This paper will present a detailed system design study for an integrated facility that combines the capabilities of an arc-jet and an expansion tube. The test model will be heated using the small-scale arc-jet Osney Plasma Generator (OPG). Then, the preheated model will be exposed to the hypervelocity flow generated from the Cold-Driven Expansion Tube (CXT). The paper will explore if this design can provide a more comprehensive simulation of atmospheric entry conditions using a system study approach.
