Blainjett’s hemi-rotor concept promises unprecedented VTOL performance
Blainjett's fascinating hemispheric rotor concept is a totally unique and left-field approach to VTOL flight. The company (no relation to me, for the record!) came up with the bones of the idea while working on the Horizon eVTOL hoverbike, which we covered back in January, and trying to solve the problem of how to generate lots of efficient vertical thrust without taking up large amounts of space or exposing bystanders to fast-spinning propellers.You could use a bunch of small ducted fans, something like what Lilium is…
