PORTER 'Gyropachute' (J. Robertson Porter, 9 Gray's Inn Square, London EC)
This vertical lift machine was exhibited at the Aero Show at Olympia in March 1913 by Messrs. Dagnall, Mallinson and Porter. It consisted of a frame of steel tube, over which was formed a bell shaped covering with a flexible skirt. Inside this was a rotor driven from below, by a Gnome rotary engine, with the fifteen gallon and two gallon fuel and oil tanks revolving with the engine. A smaller parachute surface at the bottom encompassed the pilot's station, at the base of the machine. The control of horizontal movement was obtained by manipulating sections of the skirt to release some of the air pressure.
Power: 50hp Gnome seven-cylinder air-cooled rotary

WHAT THERE WILL BE TO SEE AT OLYMPIA.
THE MACHINES.
Mr. J. R. Porter, A.M.I.C.E.
A helicopter will be shown on this stand, a general idea of which can be gathered from the sketch we publish. The machine will consist of two parachute surfaces, one above the other, with a centrifugal propeller, driven by a 50-h.p. Gnome motor, mounted between them. The engine will be provided with gearing, so that the propeller may be reversed. Means will be provided to produce a forward motion by the use of flaps, which, the inventor states, control the air travelling between the two surfaces. The diameter of the outer parachute will be 14 ft., and the machine will stand about 11 ft. high. Accommodation is provided for the pilot in a small boat or coracle swung some distance below the parachute surfaces.
