The Bristol Type 62 Ten-seater (" ten-seater ") was a single-engine, double-decker airliner made by the British manufacturer Bristol Airplane Company in the early 1920s. Only one copy was made of it, as well as the almost identical Type 75 Ten-seater and the military version Type 79 Brandon .
history
In the years 1919 and 1920, Frank Barnwell, Development Director of the Bristol Airplane Company , designed a range of civil aircraft models, from the single-engine three-seater to the four-engine variant with ten passenger seats. None of these planes was realized.
In early 1921 the British government decided to give financial support to established airlines. Barnwell then began developing a single-engine transport aircraft. In addition to a pilot in an open cockpit, it should be able to accommodate nine passengers in a closed cabin. A Bristol-Jupiter engine was provided as drive . Since this was not yet approved, the prototype was fitted with a Napier Lion engine with 330 kW.
The first flight of the Type 62 Ten-seater took place on June 21, 1921. In 1922 it came into the possession of the Instone Air Line , which it used on the route between London and Paris . It was later taken over by Handley Page Transport .
The second aircraft, the Bristol Type 75 , received a Jupiter IV engine with 315 kW. Since two pilots were now planned, the capacity was reduced to eight passengers. The first flight took place in July 1922. The machine originally intended for Instone came into the possession of the successor company Imperial Airways in 1924 . Since this only wanted to carry out its passenger transport with multi-engine aircraft, the Type 75 was converted to the Type 75A Express Freight Carrier and used between London and Cologne from July 1924 . In 1926 it was decommissioned.
A second Type 75 was still in production, but was no longer completed and sold to Instone in 1924 as a spare parts dispenser.
On behalf of the Royal Air Force which was created Type 79 , which was to serve as a troop transport and air ambulance. It received revised wings and a Jupiter IV engine served as a drive. The cabin had space for three stretchers and a paramedic or two stretchers and four seated patients. This model first flew in March 1924. After delivery, it was named Brandon . Together with an Avro Andover , it was used for patient transport in south-east England .
