Short Brothers: Knuckleduster

From Graces Guide
March 1934.

Note: This is a sub-section of Short Brothers.

The Short R.24/31 (or Short S.18 and nicknamed the Knuckleduster) was a twin-engined, high-wing cantilever, gull winged monoplane flying-boat designed and built by Short to Air Ministry specification R.24/31 for a "General Purpose Open Sea Patrol Flying Boat". The contract also specified the use of the experimental Rolls-Royce Goshawk engine. The Saunders-Roe London and the Supermarine Stranraer competed successfully for this contract.

Although it never saw military service, the Knuckleduster provided useful information on the steam-cooling of engines and the handling of monoplane flying-boats; much experimental data gathered contributed to the design of the successful Empire and Short Sunderland aircraft.
