Die NASA bringt die Rotoren von Mars-Helikoptern zum ersten Mal überhaupt auf Schallgeschwindigkeit – die Rotoren von „SkyFall“-Flugzeugen der nächsten Generation erreichen 3.750 U/min, zehnmal schneller als normale Hubschrauber

A lot less air resistance at Martian atmospheric pressure.
Fun fact: if you run the numbers on rotor speed and diameter for a bunch of different helicopter models, they usually run tip speeds of M0.6 – M0.8
Past the speed of sound on Mars* that’s an important clarification. On Earth they’re still subsonic
I thought the first ingenuity helicopter already had supersonic rotors?
Wouldn’t it stop generating lift once the blade become supersonic?
What will this do for the craft on Mars? Will it be able to go faster, better maneuverability or just be more energy efficient?
How durable is this mega-fast moving blade doing “its thing” in Mars’ conditions?
