The Porter Gyropachute was a 1910s experimental direct-lift machine designed by James Robertson Porter.
Design and development
[edit]James Robertson Porter was an Australian-born civil engineer, resident in the United Kingdom, who became interested in flight in the mid-1900s. He developed a series of un-crewed test-rigs which incorporated annular fans fitted with vertical blades, drawing air down and through a set of two superimposed annular surfaces.[1]
Porter's fourth, and first full-size, craft was called the Gyropachute. It consisted primarily of two superimposed parachute-shaped surfaces. An opening of 3 ft (0.91 m) diameter in the uppermost surface allowed air to be drawn in by 6 ft (1.8 m) wide impeller, fitted with vertical blades, powered by a 50 hp (37 kW) Gnome rotary engine.[1][2] The air would be expelled out through an annular shroud created by the lowermost surface, creating lift. Segmented flexible skirts arranged around the circumference of the outer shroud could be controlled by the pilot, via a steering wheel, to manoeuvre the craft.[3]
The Gyropachute was exhibited at the 1913 Olympia Aero Show. It is not known if the craft was tested, or if it flew.[2][4]
