Bristol 109

2 min read

In the mid-1920s, the British Air Ministry issued a specification for a long-range aircraft capable of covering a distance of 5000 miles without a single stop. In response, Bristol Aeroplane Co. Ltd. designed the Bristol Type 109 in 1928 to meet this ambitious long-distance flight requirement.

Designing for Long-Range Endurance

To satisfy the specification’s demands, it was necessary to integrate 13 fuel tanks into the aircraft, holding a total capacity of over 4000 liters. This formidable fuel capacity was crucial for its endurance mission.

Flight Trials and Legacy

The aircraft’s maiden flight occurred on September 7, 1928. During trials, it achieved a maximum flight range of 3300 miles (5310 km), which, however, was significantly less than what the Air Ministry required. Consequently, the aircraft was subsequently used only for experimental purposes, notably testing the new Bristol Jupiter XF engine.
