Downdraught

Unlike a wing-borne aircraft, a helicopter remains aloft through thrust rather than lift.

A rotor is a variation of a propellor which propels a large mass of air at a low velocity. However, in this video I failed to appreciate the product of large x slow and stood perhaps a little too close... The onset of buffeting should have been my warning.
