NASA Researchers Develop New Mars Helicopter Blade Designs to Enable Longer and Heavier Flights
NASA researchers are developing new rotorcraft blades for future Mars missions that could allow helicopters to fly much higher, farther, and carry heavier scientific payloads than current designs.
NASA researchers are developing new rotorcraft blades for future Mars missions that could allow helicopters to fly much higher, farther, and carry heavier scientific payloads than current designs. The research builds on the historic success of NASA’s Ingenuity helicopter, which achieved the first powered flight on another planet.
Engineers at NASA’s Ames Research Center collaborated with Imperial College London and Nagoya University to design a new airfoil, or blade cross-section, named roamx-0201. Utilizing computer simulations and wind tunnel tests, the team created a thinner, asymmetrical shape that differs significantly from traditional rounded blades.
Published on September 22 in a journal by the American Institute of Aeronautics and Astronautics, the findings indicate the redesigned blades could extend single-flight distances from Ingenuity’s 0.7 kilometers up to 18.7 kilometers.
The roamx-0201 design succeeds by delaying drag divergence—a sudden drop in performance when rotors approach the speed of sound, which is lower on Mars than on Earth. The blades also intentionally disrupt the boundary layer of air at the leading edge. This controlled turbulence pulls the blade upward, creating more effective lift. Additionally, the new design showed improved behavior during stall conditions, where flight normally becomes unstable, allowing future craft to operate safely across
