They used five Plymouth flathead straight-6 engines in a radial design where the tank could keep going if one engine was disabled.

It was a single-row, 9-cylinder air-cooled radial design.

Conceived and designed by Mead, the new engine would be a large, air-cooled, radial design.

It was a nine-cylinder, air-cooled radial design.

The Annex, which was completed in 2002, has a radial design that is stylistically compatible with the original building.

Discs with a radial design are also used, as these are considered gentler on the material being spheronised.

Winchester Prison was built to a Victorian radial design, with five 'spokes' radiating from a central hub.

It is only with the sequence of "fully centralised, circular and radial designs" that clear parallels are visible.

Again, therefore, the importance of radial designs is clear.

A new design, a 7-cylinder water-cooled radial design, was then developed by Canton and Unné.
