Beardmore Inflexible

William Beardmore and Company · United Kingdom · first flew 1928 · bomber

The Beardmore Inflexible was a massive British experimental heavy bomber of 1928, built to explore all-metal cantilever monoplane construction on a giant scale. With a wingspan exceeding 48 metres, it was one of the largest aircraft in the world at the time of its first flight.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Unmistakable due to its enormous span, high cantilever monoplane wing with three buried engines, smooth all-metal skin, and massive overall proportions relative to 1920s aviation.

History

Designed by Adolf Rohrbach and built by William Beardmore and Company, the Inflexible first flew in 1928. Its enormous stressed-skin all-metal structure was pioneering, but the aircraft was severely underpowered for its weight and demonstrated poor performance. Only one was built, and it was used purely for research. Despite its impressive size, it flew only a handful of times before being scrapped.

Variants

Only one prototype was built; no variants were planned.

Where you'll see it

Purely experimental; used for structural and aerodynamic research by the Royal Air Force in the late 1920s before scrapping.
