Aerospace Testing Alliance Outside Machinist Jeffrey Fulmer conducts a test probe inspection at the Arnold Engineering Development Center (AEDC) Aerodynamic and Propulsion Test Unit (APTU) facility. The inspection is part of an ongoing major capability upgrade to APTU. The ongoing project includes a new combustion air heater (CAH) at APTU. The CAH, which underwent a successful preliminary burn using butane, is a crucial part of the upgrade, officially called the Hypersonic Air-Breathing Propulsion Test and Evaluation Capability (HAPTEC). This upgrade will provide AEDC with a high fidelity flight simulation capability in support of emerging missile-class hypersonic weapon systems and vehicles. (Photo by David Housch)
