Test Facility Capabilities

Component/Engine Test Facility

The E-2 Test Facility has two test cells capable of accommodating multiple programs at the same time. Cell 1, formerly known as the High Heat Flux Facility, was originally constructed to support materials development testing for the National Aerospace Plane by subjecting special test articles to extreme temperature conditions.  Cell 2 performed Return-To-Flight testing for NASA following shuttle accidents, including frost testing and External Tank diffuser testing.  Other test projects at the E-2 Test Facility have included composite cryogenic tanks, turbo-pumps, pre-burners, and chemical steam generators.  The E-2 Test Facility is easily adapted to alternate open-loop scenarios and closed-loop schemes with minimal hardware changes.
