Sibylle Walter is the first researcher in the Busemann Advanced Concepts Laboratory to receive the NASA Aeronautics Scholarship Award. The award is a two year, with an option for a third year, fellowship. The fellowship provides a $35,000 yearly stipend, tuition, and an opportunity to spend a summer interning at a NASA facility. Read more about her award in this Colorado Daily article.
She won the award with her proposal to design, build, and test a miniature turbine based combined cycle (TBCC) engine. TBCC engines were first used on the SR-71 Blackbrid, which featured a translating inlet spike and a Pratt and Whitney turbojet with an afterburner. During the "ramjet" mode, the translating spike would close off the airflow to the turbojet and instead re-direct it to the afterburner, which would operate solo as a ramjet. There has not been another TBCC engine used, although the National AeroSpace Plane (NASP) was planned to be a TBCC driven vehicle.
