What are the advantages of a radial engine over an in line liquid cooled engine?

Air-cooled radial engines have quite a few advantages over their inline cousins. They’re lighter than liquid-cooled inline engines and since they don’t rely on coolant, they’re more damage-resistant. Radial engines are simpler – the crankshafts are shorter and they need fewer crankshaft bearings.

What are the advantages of an inline engine?

The straight cylinder configuration reduces the need for balancing components, reducing the mechanical complexity of the engine. Inline car engines suffer from relatively small amounts of unwanted vibration at typical engine speeds, and the long stroke of their cylinders gives these engines superior torque.

Are radial engines more reliable?

Reliability – Simply put, the radial engine is generally much more reliable. This is because it features a shorter crankshaft, simpler design, and creates less vibration. That less vibration means that it will suffer from greatly reduced levels of wear and tear during use.

What are the advantages and disadvantages of inline engine?

What are the advantages of radial engines over inline engines?

Air-cooled radial engines have quite a few advantages over their inline cousins. They’re lighter than liquid-cooled inline engines and since they don’t rely on coolant, they’re more damage-resistant. Radial engines are simpler – the crankshafts are shorter and they need fewer crankshaft bearings. They’re more reliable and run smoother.

What did radial engines compete with in WW1?

At the time, they competed with rotary engines and inline water-cooled engines. But, by the end of World War I, rotary engines reached their peak and radial engines quickly overshadowed them.

What is the compromise for a radial engine?

The compromise is a flat (boxer) engine with 2 or 3 cylinders on each side. This also overcomes two other problems with radials: upper cylinders obstructing pilot view and oil collecting in the lower cylinder when stopped. You also have at least one of these problems with an inline, depending if you mount it upright or inverted.

What fighter jets have water cooled engines?

The Russians copied the B-29 design for their long range bombers and eventually replaced the radial engine with water cooled engines. Other top notch fighters, the P-51 Mustang, the BF 109, the Supermarine Spitfire were water cooled.
