Each of two swashplates of NASA’s Ingenuity Mars Helicopter controls the pitch of the relevant rotor blades as they rotate and are critical to stable, controlled flight. Each swashplate is driven by three small servo

motors.

The Ingenuity Mars Helicopter was built by JPL, which also manages the technology demonstration project for NASA Headquarters. It is supported by NASA’s Science, Aeronautics Research, and Space Technology mission directorates. NASA’s Ames Research Center in California’s Silicon Valley, and NASA’s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity’s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Martin Space designed and manufactured the Mars Helicopter Delivery System.
