The Bristol Pullman was a British prototype passenger aircraft developed from the Braemar triplane heavy bomber.

Design and development

The Pullman was developed as a 14-passenger variant of the Braemar bomber. The third prototype Braemar was completed as the prototype and sole Pullman and first flew early in May 1920. It was shown at the International Aero Show at Olympia in July of that year, where its great size and interior fittings were much admired. The Pullman was one of the earliest British aircraft to have a fully enclosed crew cabin, and this feature was disliked by service pilots, who often carried fireman's axes with them to enable them to escape in an emergency.

Operational history

Ultimately the Pullman was not accepted for squadron use by the Royal Air Force, nor was it selected for use by any civil operator. The prototype was the sole example of the type constructed or configured.

Variants

Type 26 Pullman: Passenger variant of the Braemar bomber powered by four Liberty L-12 engines, one built and first flown in May 1920, sometimes known as the Pullman 14.
Type 33 Pullman 40: Proposed upscaled 40-passenger variant, it was to be powered from a central engine room, at first with four 500 hp (373 kW) Siddeley Tiger engines and later by two 1,500 hp (1,119 kW) steam turbines. A smaller testbed for the central engine room concept was built as the Tramp.
