Bristol Hydra (original) (raw)
The Bristol Hydra (also known as the Double Octagon) was an experimental 16-cylinder, twin-row radial aircraft engine built by the Bristol Engine Company. It is a relatively rare example of a radial with an even number of cylinders per row – it is often claimed that radial engines require an odd number of cylinders, but this is simply easier, not physically required. Only two Hydras were built, the type never entered production.

Es un raro ejemplo de motor radial con cilindros en número par; con frecuencia se afirma que los motores radiales requieren un número impar de cilindros, pero esto es porque es más sencillo, y no por un requerimiento físico. Sólo se construyeron dos Hydras, y el modelo nunca entró en producción.
