NASA Ames, Tohoku University and ³Ô¹ÏºÚÁÏ researchers win award for testing new Mars rotor aerofoils, advancing future helicopter performance on Mars.

A joint team from NASA Ames Research Center, Tohoku University, and ³Ô¹ÏºÚÁÏ has been recognised with their second NASA Group Achievement Award for advancing Martian rotorcraft aerofoil research. Among the awardees are Dr. Lidia Carós Roca, Professor Oliver Buxton, and Professor Peter Vincent from ³Ô¹ÏºÚÁÏ’s Department of Aeronautics. 

The citation recognises the team “for conducting the first experimental test program to assess next generation rotor airfoil designs that will provide substantial leaps in mission performance for future rotorcraft on Mars. This test program demonstrated and reported the large benefits of these new airfoil designs relative to the airfoils used on the Mars Ingenuity Helicopter rotor.” 

The experiments were conducted in the Tohoku University Mars Wind Tunnel, a unique facility housed within a vacuum chamber and capable of replicating the low-pressure, low-density conditions of Mars at high subsonic Mach numbers. Specifically, the experiments compared the Ingenuity helicopter aerofoil (CLF5605) – a 5% thick, cambered, tear-drop profile used on the outer half of Ingenuity’s blades – with a next-generation ROAMX-0201 aerofoil, a 1% thick unconventional design optimised for Mach 0.60 and Reynolds number 20,000, onditions representative of Mars rotor operation.   

Measurements included lift and drag balance data, Pressure Sensitive Paint (PSP) for detailed surface pressure distributions, and Schlieren imaging to visualise flow fields. Angles of attack from –2° to +6° were tested, representative of hovering conditions for Martian rotorcraft. The resulting dataset – one of the most comprehensive of its kind – provides critical validation material for high-fidelity computational models and will guide the design of future Mars rotorcraft capable of greater range, endurance, and payload capacity.
