AirCo DH.10 (Amiens)

1918 WORLD WAR 1

History

In the last year of the First World War (1914-1918), Geoffrey de Havilland of AirCo developed an entirely new twin-engine biplane bomber in the form of the "DH.10". Its maiden flight took place on March 4, 1918, and the model was launched in November of that yearthe same month the war officially ended. As a result, the series left no trace of the Great War and production was limited to 258 units, most of which arrived in the postwar period. The UK became its sole global military operator, with bombers serving in one form or another in a total of eight squadrons.

Some continued community service in the UK and the US until the early 1920s.

Department of Health. The 10 was built in response to Britain's need for a new bomber to end the war. De Havilland modified the earlier DH. The 3-wing platform was the norm, and prototypes were quickly arranged for testing.

This form - the 'Amiens Mk I' - was powered by 2 x Siddeley 'Puma' engines rated at 230 hp and configured in a 'propeller' arrangement (propellers back). The design did not impress the British authorities, who thought it was too slow, so this led to a redesign of the already revised aircraft, which now features 2 Rolls-Royce Eagle VIII production engines , 360 hp each, with a more traditional traditional "puller" insert. configuration. In this form - "Amiens Mk II" - the project was a success.

However, due to the inability to use the Eagle engine, the production model - the "Amiens Mk III" - was equipped with an American "Liberty" 12 series 395hp engine, and it was this model that proved to be the hallmark of the Royal Air Force (RAF). , Amiens officially adopted DH.10.

A total of 221 Amiens Mk III were produced. The Amiens Mk IIIA (DH.10A) is a 32 gauge version with the engine mounted on the lower wing assembly (rather than suspended between the upper and lower wing assemblies like the Mk III).

The Amiens IIIC (DH.10C) is a limited production model (5 prototypes) with Eagle engines as insurance for Liberty engine availability in the United States.

The aircraft remained in service until 1923 before it was finally scrapped.

After DH is done. 10 has a trio. Dimensions include a length of 12 meters, a wingspan of 20 meters and a height of 4.4 meters. Curb weight is 5,750 lbs and maximum takeoff weight (MTOW) is 9,050 lbs.

Power comes from 2 Liberty 12A V12 engines, each producing 400 horsepower and a top speed of 130 mph, with a service ceiling of 19,000 feet and a mission duration window of 6 hours. It takes 11 minutes to ascend to 10,000 feet.

Defense weapons are 1 or 2 x . 303 Lewis machine guns on trainable (scarf) wings. These guns were located in the bow and center of the hull to help defend against slow-moving bombers. Internally provided conventional throwing weapons up to 920 lbs.
