Bristol Aquila

The Aquila was a 9-cylinder single-row radial aircraft engine produced by the Bristol Engine Company starting in 1934. It was the world's first production sleeve valve aircraft engine and its basic design was used in the sleeve valve Bristol Perseus, Bristol Hercules, Bristol Taurus, and Bristol Centaurus.

The first Aquila engine delivered a modest 365 horsepower (270 kW), which was hardly spectacular for an engine of this size. It soon developed into more powerful versions as improvements were worked into the line (as well as similar changes to the Perseus), and by 1936 it had improved to 500 hp (370 kW). This made it an excellent replacement for the Bristol Jupiter, which ended production at 590 hp (440 kW) three years earlier, but by this time almost all interest was on ever-larger engines.
