NASA test: helikopterbladen houden supersone snelheden op Mars vol

NASA engineers have successfully tested advanced rotor blade designs that can withstand supersonic speeds exceeding Mach 1.08, removing a major structural barrier for future Mars helicopters. The tests confirm that composite blades can maintain integrity under the extreme rotational stresses needed to generate lift in Mars's thin atmosphere, which is only 1 percent as dense as Earth's sea level. While the Ingenuity helicopter operated at subsonic speeds up to 0.7 Mach, next-generation Mars rotorcraft designed for heavier payloads would require supersonic-capable blades, and this breakthrough
