Hi again folks,
Sorry for the patent bombardment today from me and promise this is my last patent post for a wee while.
Anyway, here’s one of the Heliplane patents due to Peter F. Girard and filed January 16th 1961.
“The primary object of this invention therefore, is to provide a heliplane type aircraft having a pair of delta wings which provide lift for the aircraft in forward flights with the wings fixed, the wings also having movable tips which act as propeller blades and being rotatable in opposite directions for vertical thrust in the manner of a helicopter.”
