Latest Patents

One of Harshman's latest patents is a scramjet combustor designed for hypersonic flight vehicles, specifically those operating at Mach numbers greater than 5.5. This innovative combustor features a housing with two spaced-apart, generally opposing, and longitudinally extending walls. Each wall incorporates an aft-facing step where fuel, such as hydrogen, is injected into the shear zone along the separation line. This design improves fuel-air mixing, which is essential for efficient combustion. The longitudinal distance between the steps is meticulously controlled to leverage the aerothermo compression provided by the shock from the forward step. Additionally, the back portion of each wall is positioned transversely inward toward the combustor's longitudinal axis to further enhance mixing effectiveness.
