Insinyur NASA capai terobosan rotor supersonik untuk helikopter Mars

Para insinyur di Jet Propulsion Laboratory NASA telah berhasil menguji bilah rotor yang lebih besar yang berputar lebih cepat dari kecepatan suara tanpa mengalami kerusakan. Pencapaian yang diumumkan pada hari Kamis ini meningkatkan kemampuan angkat sebesar 30 persen untuk misi Mars di masa depan.

Pengujian dilakukan di dalam ruang simulasi atmosfer tipis Mars, di mana ujung rotor mencapai kecepatan Mach 1,08. Para insinyur di JPL dan AeroVironment menggunakan desain tiga bilah dan dua bilah, di mana desain dua bilah sesuai dengan konfigurasi yang direncanakan untuk misi SkyFall. Sebuah kipas di dalam ruangan tersebut mensimulasikan angin sakal seiring dengan peningkatan kecepatan, dan tim mengamati hasilnya dari ruang kendali di dekatnya.
