This work investigates the application of recycle-rescaling inflow techniques to hypersonic turbulent chemically-reacting boundary layers. While current high-fidelity simulations resolve the entire laminar-to-turbulent transition due to challenges in prescribing realistic inflow conditions, this study evaluates a potential strategy to bypass such computational demands. The analysis begins with a simplified two-species reacting gas, where inflow-generated fields are compared against reference DNS to evaluate relaxation behavior. The methodology is then extended to a five-species air mixture representative of realistic high-enthalpy environments. Preliminary results aim to assess whether, under controlled conditions, synthetic turbulent inflows could significantly reduce domain size without compromising physical fidelity.
