SPECIAL TYPES AT THE DISPLAY
WESTLAND "PTERODACTYL"
THIS machine is a development of the "Pterodactyls" shown at previous Displays. Designed by Captain G. T. R. Hill and built by the Westland Aircraft Works, the Mark IV is a three-seater cabin machine, fitted with the 120-h.p. "Gipsy" inverted engine.
The "Pterodactyl" has no tail, the back-swept wings giving the fore and aft stability attained in orthodox machines by means of a tail. The ailerons perform the functions of fore and aft and lateral control. Used together they act as elevators, while used in opposition they act as normal ailerons. Directional control is by the rudders on the wing tips.
The "Pterodactyl IV" has the inverted "Gipsy III" engine mounted at the back of its fuselage and driving a pusher airscrew. The gross weight is 2,000 lb. (910 kg), and the maximum speed 110 m.p.h. (177 km./h.). The endurance is 4 1/2 hr. at a cruising speed of 90 m.p.h. (145 km./h.).

THE NEW PTERROR: The Westland Pterodactyl (Gipsy) appeared in new colours for the purpose of monster-chasing.
The latest of the Pterodactyl series, the Mk IV, appeared in a monstrous colour scheme at the 1932 pageant. -

EXPERIMENTAL RESEARCH: THE HANDLEY PAGE "GUGNUNC," THE CIERVA "AUTOGIRO," AND THE HLLL-WESTLAND "PTERODACTYL" IN FLIGHT FORMATION. RIGHT-HAND CIRCUITS WERE MADE SO THAT THE GUGNUNC COULD "MARK TIME" WHILE THE "PTERODACTYL" WENT FULL SPEED.

Flight 1931-06 / Flight
Westland, following upon the Pterodactyl l experience, elected to forego the Mk. II and III projected tailless fighters in favour of the more modest Mk. IV three-seater research vehicle. The sole example, K1947, first flew in June 1931 and was powered by a 120hp DH Gipsy III. The Mk. IV's maximum achievable speed in level flight was 113mph. Interestingly, in an effort to cure the roller-coaster excursions of the Mk. I, Capt. Hill reverted to using elevons on the Mk. IV, in place of swivelling wingtip, but the pitch control problems appear to have remained unaffected.

Air Enthusiast 1996-07 / A.Pelletier - Towards the ideal aircraft? (1)
The Westland-Hill Pterodactyl IV was a three-seat cabin machine, powered by a 120hp de Havilland Gipsy III, and was fitted with a completely revised control surface system. During the tests, which spread over several years, the highest incidence reached was 24.5°, but the machine was found to be overweight.

WILL IT COME TO THIS?: A FLIGHT Artist's conception of the result of combining three types which seek to avoid stalling and spinning; the Autogiro, the "Ente" and the Pterodactyl. The name might be something short and snappy, like "Pteroautogirentedactyl."
