DART Jet Engine 1

The DGEN380 Aero-Propulsion Research Turbofan (DART) is a small-scale jet engine NASA uses to test new aviation technology. DART is seen here inside its host facility, the Aero-Acoustic Propulsion Laboratory at NASA's Glenn Research Center in Cleveland. This soundproofed chamber ensures researchers can understand the level of noise the engine is producing, as well as keeping the volume low outside.
