Ballistic multi-parachute system saves eVTOL in low-altitude fall | eVTOL

What happens when something goes very wrong in an eVTOL aircraft? China’s AeroHT has released video of its innovative low-altitude multi-parachute system turning a catastrophic propulsion system failure into a soft-ish landing from just 50 m (164 ft) up.

For many years, eVTOL aircraft manufacturers have been talking about using ballistic parachutes as a last-resort safety measure, and we’ve been wondering just how practical that kind of thing could possibly be from altitudes below about 100 m (328 ft), where such systems will have precious little time to deploy.

AeroHT has now answered that question, by releasing a video of its own multi-parachute safety system deploying from an X2 manned multicopter prototype at just 50 m off the ground. The chutes start grabbing air within about a second and a half of blasting out of the front of the aircraft, they’re fully deployed by about a second…
