It looks to me like the designers were having trouble getting enough base drive current into Q101, Q102 during peak load current transients, so they put in CR5 to boost the base drive a bit. This may have led to the failure you have seen. Removing CR5 will probably work fine. The output peak...
In a hover, the blade tips are at a constant speed and it is generally 150-200 kts below Mach 1 (Sea level). At max Vne the tips going forward come pretty close to Mach 1, but as they go aft they drop below their hover speed by the forward velocity of the aircraft. At least that is how I...
Does anyone here know if the blade tips on helicopters get hot due to aerodynamic heating? Alternately does anyone here know a good reference for how to estimate how hot they get? I understand aerodynamic heating starts to become significant at Mach .8 or so. Does anyone have a formula for the...
