The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of ...
The radial aircraft engines provided greater power-to-weight ratios and were more reliable than conventional inline vehicle engines available at the time. This reliance had a downside though: if the engines were mounted vertically, as in the M3 Lee and M4 Sherman , their comparatively large diameter gave the tank a higher silhouette than ...
The Wright R-2160 Tornado was an experimental 42-cylinder, 7-cylinder per row, 6-row liquid-cooled inline radial aircraft engine.It was proposed in 1940 with 2,350 hp (1,752 kW) for experimental aircraft such as the Lockheed XP-58 Chain Lightning, Vultee XP-68 Tornado, and the Republic XP-69.
Radial engines have cylinders mounted radially around a central crankcase. Rotary engines have a similar configuration, except that the crankshaft is fixed and the cylinders rotate around it. (This is different from the Wankel engine configuration described below.) Radial and rotary engine designs were widely used in early aircraft engines.

The Curtiss H-1640 Chieftain was an unusual American 12-cylinder radial aero engine designed and built by the Curtiss Aeroplane and Motor Company in the mid-1920s. [1] In contrast to most multi-row radials, where the cylinders in the rows are staggered to present better airflow for cooling, the Chieftain used the inline radial arrangement with the cylinders behind each other to allow pairs of ...
The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly 3,350 cubic inches (54.9 L). Power ranged from 2,200 to 3,700 hp (1,640 to 2,760 kW), depending on model.
Louis was joined by his brother Laurent who designed a rotary engine specifically for aircraft use, using Gnom engine cylinders. The brothers' first experimental engine is said to have been a 5-cylinder model that developed 34 hp (25 kW), and was a radial rather than rotary engine, but no photographs survive of the five-cylinder experimental model.
