How many rpm is the Wright Flyer engine?
The completed engine weighed 180 pounds and developed 12 horsepower at 1025 revolutions per minute. The body of the first engine was of cast aluminum, and was bored out on the lathe for independent cylinders. The original airframe was designed to be powered by a rolls-royce merlin engine producing 1,030 hp (768 kw). It was strong enough and adaptable enough to use increasingly powerful merlins, and in later marks, rolls-royce griffon engines producing up to 2,340 hp (1,745 kw).Rolls-Royce developed the engine from 1933 from an engine called the PV12. Initially of about 900 to 990 horsepower on the bench, then in full production, once made reliable, in the Mk I Spitfire and the Hurricane with over 1100 horsepower. The Merlin engine is a small engine.
