PERMIT NO. 29 February 6, 2017 AEDC H2 Arc Heater team validating new test capability after upgrades By Deidre Ortiz AEDC Public Affairs To meet development and testing needs for long- range strike and hypersonic vehicle materials, the H2 Arc Heater at AEDC has been upgraded, with check- outs being performed recently to ensure the modifica- tions were successful. According to Harry Clark, AEDC senior engineer with the Strategic Plans and Test Facility Require- ments, this project, known as the Mid-Pressure Arc Heater Prototype project or MPAH, has been a risk reduction effort that supports the Central Test and Evaluation Investment Program (CTEIP) project up- grading the H2 arc-jet test capability. “The Test & Evaluation, Science & Technology branch of the Test Resource Management Center identified in 2014 the opportunity to ensure the suc- cess of the MPAH project by funding the installation of a segmented arc heater in H2 and demonstrating its performance envelope,” Clark said. “The project was funded in 2015 and has nine test conditions that comprise the Key Performance Parameter for the risk reduction effort. Successful demonstration of the KPP is required before the CTEIP project can proceed to execution.” The facility modifications necessary to install the The H2 Arc Heater at AEDC has recently been upgraded, and checkouts are being performed to ensure the segmented heater in H2 were designed by AEDC en- modifications were successful.
