Bristol Braemar & Pullman

A strategic bomber that evolved into a commercial transport that was ahead of its time.

The Bristol Aeroplane Company Type 24 Braemar was designed as a strategic bomber for operations against Germany.  It was conceived in response to the establishment of the Independent Air Force towards the end of World War One and designed for bombarding railway yards, aerodromes and important industrial installations.
 
Initial designs favoured a central engine room configuration with shaft-driven propellers in pairs. However, this was soon abandoned as too complex and the large four-engine triplane was eventually built with the power units installed in 'push-pull' pairs, mounted on the upper surface of the middle wing.
 
The first prototype (C4296) was flown on 13th August 1918, eventually being powered by the Siddeley Puma inline engines (the more powerful Rolls-Royce Eagle having been the intended powerplant).

This was followed by the improved Bristol Type 25 Braemar II (C4297), using four Liberty engines which first flew on 18th February 1919. A third aircraft, the Bristol Type 26 Pullman (C4298), was completed in a 14-seat transport configuration and made its maiden flight in May of 1920. This aircraft later received a civilian registration (G-EASP).
 
Radically for the time, the Pullman featured a fully enclosed cabin for the flight crew and 14 passengers.

The unsuccessful Bristol Type 25 Tramp was intended to be a cargo-carrier and featured four engines mounted within the fuselage (again using shafts to drive two tractor propellers mounted on the middle wing). Whilst two airframes were built, these were broken up at Farnborough on 1922 without having flown.
