The Bristol Braemer triplane began life as a long range heavy bomber, designed for missions deep into Germany.
The aircraft was planned with a centralized location where all four of its engines would be situated. The propellers were to be driven through long shafts and gear boxes. After further consideration, it was decided that the weight and complexity of such and arrangement would detract from the overall performance of the aircraft. Eventually its four engines were arranged two per wing in push-pull configurations.
The first Bristol Braemar took to the sky in August of 1917. While it demonstrated adequate handling, it was somewhat under powered. A second prototype had more powerful engines. However, when the War came to an end, a long range heavy bomber was no longer necessary. It was decided to build a third prototype as a passenger transport.
The passenger prototype Bristol Braemer first flew in May of 1920. It had a cabin with seating for fourteen passengers. Pilots found it difficult to see out of its enclosed cockpit. The aircraft lacked flaps and brakes, and it had a relatively high wing loading. The flat sides of the aircraft made it difficult to land in cross winds. With all the factors working against it, the Bristol Braemar project was dropped in December of 1921.
