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.
for use during the 2030s and beyond. If all goes well, the technology could proceed to more exhaustive tests involving larger facilities such as NASA’s wind tunnels. DART tests are run from the Mobile Control Unit – a large van converted into a high-tech control facility with video monitors reporting live data from the engine. In this image, two engineers supervise an engine test, with the nearest researcher operating DART’s thrust lever.Among its features, DART has a high bypass ratio, which is a measure of how much air passes through the turbofan and around the main core of the engine as opposed to entering it.
