Rotors for Mission to Titan Tested at Langley’s Transonic Dynamics Tunnel

A key component of the 8-rotor Dragonfly vehicle that will make that journey to Titan recently underwent testing at the Transonic Dynamics Tunnel (TDT) at NASA's Langley Research Center in Hampton, Virginia.

Similar to a drone, Dragonfly will traverse Titan's dense, nitrogen-rich atmosphere, then land on, sample and examine various sites. Dragonfly will have four pairs of rotors, each with two rotors in coaxial configuration, meaning one rotor above the other. It's similar to, but significantly larger than, a typical terrestrial drone, as the vehicle is over 12 feet both nose to tail and at the widest points, rotor tip-to-tip.
