StrongEagle mentioned:
For fun, I want to compute the energy of an IP disc at full throttle... something like 8,000 RPM at max rotor speeds. But, I have not been able to find any information as to the approximate diameter and mass of an IP disc throttle for this engine, making the exercise somewhat difficult.
Does anyone have approximate values for these parameters?
You could assume:-
Made of steel alloy, density 7 g/cc (or tonnes/m^3)
Uniform disk 1cm in thickness
From the pick up truck photos and the RR slides seems to be about 1m in diameter.
My guess is that the value obtained might be within a factor of 3 or so of the true value. Others have already suggested that the energy might be compared to a car at motorway speeds (or a 4kg anti-aircraft projectile at 2000ft/sec (mach 2 ish)).
Please post the results
