The Gnome-Rhône 7K Titan Major was a seven-cylinder 370 hp (270 kW) air-cooled
radial engine, that started life as an enlarged
Gnome-Rhône 5K with two extra cylinders.
Development
The Gnome-Rhône 5K was itself a licensed version of the
Bristol Titan. The 7K is very comparable to the
Bristol Neptune seven-cylinder engine since they used the same technology.[1] The 7K was followed by the larger and more powerful nine-cylinder 550 hp (405 kW)
Gnome-Rhône 9K Mistral. Gnome-Rhône later responded to the need for a more powerful engine by developing the 7K into a two-row version that became the
Gnome-Rhône14K Mistral Major.
