Corsair propeller diameter 13 feet 4 inches, ground clearance
9.1 inches, engine R-2800-8.



The corsair used a 3-blade prop. Why didn't they use a smaller 4-blade
prop if ground clearance was such an issue?

They wanted to keep the main landing gear as short as possible, to
simplify structural loads. The Hellcat had a relatively long main gear
leg.

Corsair had a 4 bladed prop. A 3 bladed prop may have been big enough to
irritate the Seabees who had no sense of humour when it came to prop blades
chewing up their runways.

It also had a 3 bladed prop. It all depends on the specific model.

The early Corsairs used a 3-blade prop, later versions had a 4-blade
prop.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

You appear to be answering a question other than the one asked.

The F4U-4 had a four-blade prop, but earlier versions had three blades,
and include a large part of what saw combat in WW2.

A four-bladed prop for the same power output should be shorter than the
three-bladed equivalent.
