NASA JPL engineers achieve breakthrough in rotor technology
Ars Technica6 h ago
The team developed a variable-curvature rotor profile that, in wind-tunnel tests, produced about 14 percent more lift at the same power draw. Microsensors embedded at the blade root captured high-resolution vibration data in real time.
The project adapts the thin-atmosphere principle inherited from Ingenuity to the denser atmosphere at Earth altitude. The results have direct industrial applications for unmanned firefighting, logistics and urban-air-taxi prototypes.
Engineers say the profile's manufacturing cost is comparable to conventional rotors. Licensing talks have begun with private aerial-mobility developers; first commercial prototypes are targeted to fly in early 2027.
