Первый из этих опытных самолетов оснащался двигателем Armstrong Siddeley Mongoose мощностью 135 л. с., а второй - двигателем Bristol Lucifer такой же мощности. Были заказаны шесть серийных самолетов, но подводная лодка вскоре затонула. Считается, что был построен только один самолет.

BRITISH AIRCRAFT AT OLYMPIA

GEORGE PARNALL & CO.

   OF the two complete aircraft to be exhibited on this stand, one will be the little "Peto" two-seater designed for service with submarines, while the other will be the new "Elf," a private owner's two-seater machine rather beyond the light 'plane class, fitted with the A.D.C. "Hermes" engine.
<...>
   The Parnall "Peto" is a two-seater reconnaissance biplane designed for service use in conjunction with submarines. It is of composite construction, the metal work being chiefly stainless steel or duralumin. The limitations on space for stowage on board a submarine called for considerable ingenuity in design to meet service requirements and at the same time produce an aircraft that was seaworthy and had a useful air performance. The "Peto" can be launched from or stowed in its base in an exceedingly short time. Provision is made for catapult starting.
   The fuselage is of rectangular form, with spruce longerons and spruce or stainless steel struts. The rounded deck fairing meets the underside of the centre-section. The fuselage is fabric covered except the sides of the front cockpit, where quickly-detachable aluminium panels are used.
   The biplane wings have spars and ribs of spruce, while the centre section and aileron spars are steel tubes. The top planes have ailerons extending the whole span, while the lower plane trailing edge is hinged for wing-folding purposes.
   A braced monoplane type of tail is used, of composite construction and fabric covered. The fin is underslung, the rear spar to which the rudder is hinged being attached to the top and bottom longerons. The tail plane has provision for trimming during flight.
   Of the twin-float type, the undercarriage has streamline struts of N-formation in side elevation, braced with cables in front and rear panels. Long single-step duralumin floats are carried cantilever fashion on front and rear booms, and can be readily removed without interfering with the bracing.
   The engine is an Armstrong-Siddeley "Mongoose," supported on a simple girder-type plate attached to the fuselage by steel tubes. A hand-starting gear is fitted in the passenger's cockpit. The engine cowling is quickly detachable, and a 14-5-gallon petrol gravity tank is fitted inside the fuselage, the 1 1/2-gallon oil tank being placed immediately below it.
   Tandem cockpit arrangement is provided, both cockpits being aft of the top centre-section. They are fitted with seat pans capable of taking parachutes or air cushions. The observer is provided with a chart case, observation instruments and a short-wave wireless transmitting and receiving set. The pilot's cockpit contains the standard joystick controls and service equipment.
   Following are the main dimensions of the Parnall "Peto": Length, 22 ft. 6 1/4 in.; span top plane, 28 ft. 5 in.; span bottom plane, 20 ft. 5 in.; width, folded, 8 ft.; height, 8 ft. 11 in.; track over float centres, 6 ft. 1/2 in.
   The tare weight is 1,300 lbs. and the loaded weight, 1,950 lbs., giving a wing loading of 11-4 lbs./sq. ft. and a power loading of 12 -65 lbs./h.p.
   The performance of the "Peto" is: Full speed at sea level 113 m.p.h.; at 5,000 ft., 107 m.p.h. Rate of climb at sea level, 600 ft./min. Climb to 5,000 ft. in 11 mins. Endurance 2 hours.
