How much horsepower can a radial engine generate?
They can produce a lot of power. A typical radial engine in a B-17 has nine cylinders, displaces 1,800 cubic inches (29.5 liters) and produces 1,200 horsepower. Radial engines have a relatively low maximum rpm (rotations per minute) rate, so they can often drive propellers without any sort of reduction gearing.
What is wrong with Pratt and Whitney engines?
Investigators said a broken fan blade caused the failure. That 777 also had Pratt & Whitney 4000 series engines, similar to the ones that failed in each of Saturday’s troubled flights. A National Transportation Safety Board report said the failure in 2018 was caused by a fan blade that broke off and damaged the engine.
