How was the 1000 Hp determined… ??? What was the max peak torsional reversal levels above and below the mean torque during the test ? ? ? What was the frequency of the max peak torsional reversal levels during the test??? What loading condition produced the most adverse peak torsional levels with each prop for which it is designed to be used and was the gear box operated at that most adverse condition long enough to accomplish a minimum of 10^7 peak torsional reversals fore each engine/prop combination for which it is to be used ??? Just some of the appropriate questions that would need to be documented… Regards, George "" The guys that are developing V-8's have a problem. They either need to cam for low RPM direct drive or use a PSRU. The Eagle 540 has a gorgeous PSRU that will handle 1,000 HP that potentially could be a bolt-on for other V-8's. It's compact and light. It has helical-cut gears with 3.4 tooth engagement, a huge benefit over spur gears. Those gears have a special hollow body for lightness. All bearings were designed by the Timken helicopter guys. It also is set up for a prop governor and has a standard prop flange. It uses its own oil (Shell Donax TC-50) and has its own filter and pump. Ted Noel """"
