NASA Pushes Next-Gen Mars Helicopter Rotor Blades Past Mach 1

The rotor blades that will carry NASA’s next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA’s Jet Propulsion Laboratory in Southern California. Data from the tests, which took place in a special chamber that can simulate environmental conditions on the Red Planet, indicate that the fastest traveling part of the rotor blade, the tips, can be accelerated beyond Mach 1 without breaking apart. Data gathered from 137 test runs will enable engineers to design aircraft capable of carrying heavier payloads, including science instruments. “NASA had a great run with the Ingenuity Mars Helicopter , but we are asking these next-generation aircraft to do even more at the Red Planet,” said Al Chen, Mars Exploration Program manager at JPL. “That’s not an easy ask. While everything about Mars is hard, flying there is just about the hardest thing you can do. That’s because its atmosphere is so incredibly thin that it is hard to generate lift, and yet Mars has significant gravity.” VIDEO By pushing rotors beyond the speed of sound during recent testing at NASA’s Jet Propulsion Laboratory, engineers are unlocking new possibilities for low-altitude aerial exploration of Mars.
