P.Lewis British Aircraft 1809-1914 (Putnam)

Dyott Monoplane

   Among the most successful of the early monoplanes was the Dyott, at the same time one of the neatest-looking of the practical aeroplanes of the period. The elegant little 50 h.p. Gnome-engined machine took its name from that of its owner. G. M. Dyott, to whose specification it was made. Its originator, who gained his Royal Aero Club Aviator's Certificate No. 114 on 17th August, 1911, on a Bleriot at Hendon, decided during the following year to construct a machine of his own design for cross-country flying. The work was entrusted to the Hewlett and Blondeau Company, the aircraft being built in their works at Clapham and completed early in 1913.
   After successful test flights, the Dyott monoplane was taken without delay by its owner on an extensive six-months tour of the U.S.A. From April, 1913, until the following October, the machine flew for some 2.000 miles, giving exhibition flights as far West as California. Reports reaching Britain from George Dyott were most enthusiastic about its reliability and lively performance. Writing from New York he claimed that it went "like a rocket", was taking off in 40 yds., and was reaching a top speed of 75 m.p.h.
   In November, 1913, the Dyott was flying again at Hendon and was entered in the London-to-Brighton Handicap, which was flown on the 8th of the month. Starting from Hendon, the nine British, French and American entrants had first to fly to Harrow Church and then set course for the Palace Pier at Brighton, the finishing-point for the first half of the contest. After flying westwards along the coast, they were to land at Shoreham, refuel and fly back to the Palace Pier, there to continue the race home to Hendon. The powerful wind blowing at the time from the West caused a miscalculation in drift, carrying the Dyott over Eastbourne, where a landing was made on Beachy Head. The machine alighted successfully, but was unfortunate enough to be blown over on to its back by a gust, leaving no option but withdrawal from the race. A projected flight to be made to India with the aircraft did not finally materialize.
   Features of the Dyott were the mid-wing and the lack of ailerons, lateral control being effected by warping of the tips. One rather undesirable aspect of the design was that the flying wires were attached direct to the undercarriage, thus subjecting the wings to the strain of landing loads. In addition to the usual flight instruments of tachometer, oil gauge, compass, petrol gauge and altimeter, the cockpit contained a special graphic recorder, designed by George Dyott, which noted by means of three pointers on a revolving drum the different movements of the controls for elevators, rudder and warping. Replacement of parts of the airframe was facilitated by a system of joining the components together with nuts and bolts. In addition to the 8 galls, oil and the main 8 galls, petrol tanks, an auxiliary of 10 galls, petrol was carried behind the pilot, giving enough fuel for 3 hrs. duration.
