Very cool; it appears to be an assist, however, without the power to actually do a takeoff.
- MiguelHudnandez 6y ago15kW should be enough to easily lift an adult human, but the stability implications are a good reason this is an assisted wingsuit and not a jetpack. Another thing to consider is that saying it has 15kW motors and 5 minutes of thrust does not necessarily mean 5 minutes at 15Kw. That would work out to 1.2kWH weighing what I guess to be about 40 pounds in batteries alone. I'm really impressed by wingsuits, and strapping a motor onto one just makes it that much cooler.
- hwillis 6y ago> That would work out to 1.2kWH weighing what I guess to be about 40 pounds in batteries alone. Absolutely not. Sony VTC4s are early 2010s cells that do 30 amps continuous with 2000 mAh capacity[1]. 172 cells weigh in at 17 lbs, 1.2 kWh, and a whopping 16.5 kW continuous rated output. For lower power applications, higher-capacity cells like the NCR18650G[2] weigh below 10 lbs per kWh.
