The Hawker Dantorp H.B. III was a Danish single-engined biplane bomber of the 1930s. The aircraft was a development of the British Hawker Horsley designed for the Danish Navy, but differed in being powered by a radial engine and having a third crew member. Two examples were built in Britain as a precursor to license production in Denmark. Financial constraints meant this was not realised and the Hawker-built examples were the only aircraft produced. They served until the German invasion of Denmark in 1940.
Design and development
The Hawker Dantorp was derived from the successful Hawker Horsley.Шаблон:Sfn Originally designed to meet Air Ministry Specification 26/23 for a day bomber powered by a single Rolls-Royce Condor liquid-cooled engine, the Horsley entered service with the Royal Air Force in September 1927.Шаблон:Sfn
One example of the Horsley, serial number J8620, was equipped with an Armstrong Siddeley Leopard 14-cylinder twin-row air-cooled radial engine.Шаблон:Sfn The Leopard was the most powerful radial engine in the world at the time and in consequence promised much better performance.Шаблон:Sfn Meanwhile, another Horsley, J8612, had been equipped with floats and demonstrated that the aircraft could be operated from the water.Шаблон:Sfn The Danish Navy showed interest in these developments and, in 1930, ordered an aircraft type based on the design of the Horsley but equipped with the new engine and able to operate as a floatplane.Шаблон:Sfn The aircraft was to be known as the Dantorp and was given the service number H.B.III.Шаблон:Sfn
Description
The Dantorp was a large single-engined two-bay biplane of composite wood and metal construction. Unlike the two seat Horsley, it had a crew of three, with an additional crew position between the pilot and observer/gunner.Шаблон:Sfn The aircraft mounted a forward-facing Шаблон:Convert Vickers machine gun, a Шаблон:Convert Lewis gun in a Scarff ring and could carry eight Шаблон:Convert bombs, two Шаблон:Convert bombs, one Шаблон:Convert bomb or a torpedo weighing Шаблон:Convert.Шаблон:Sfn
The aircraft was equipped to operate using interchangeable wheeled undercarriage and floats. The floats were designed as separate structures to allow for the carriage of a torpedo under the fuselage.Шаблон:Sfn
Operational history
The first Dantorp, serial number 201, was first flown on 19 September 1932, equipped with a wheeled undercarriage.Шаблон:Sfn The second, 202, followed shortly afterwards and was first tested with floats in November 1932. The aircraft were flown extensively in Denmark from 1933, but it took until 1935 for there to be good results from launching torpedoes.Шаблон:Sfn They were also tested as catapult-launched floatplanes for operations off warships.Шаблон:Sfn However, these trials did not lead to the adoption of the tactic by the Navy. The aircraft continued to be flown for the rest of the decade and both aircraft were operational when Germany invaded Denmark in 1940 although their subsequent history is unknown.Шаблон:Sfn
The Danish Navy purchased a licence to build a further ten aircraft at the Danish Naval Workshops (Orlogsvaerftet), but a shortage of funds meant that the license was not taken up and no further aircraft were produced.Шаблон:Sfn
