| X.4221 17.10.21. Extract from R9/G17.10.21. X.4219 CRANKSHAFT DAMPER. X.4221 We understand that the period which requires damping is at a very high speed. This, therefore, only requires a very small flywheel in weight, but possibly with a fair amount of friction. The period will get worse with higher compressions, and it might be advisable to test various compressions. We should be contect to lose a certain amount of power at the highest speed of, say, 3000 revs. R. {Sir Henry Royce} | ||
