Hot Temps, Weak Engines, and Heavy Loads
Here is a hopefully thought provoking questions pertaining to Rotary Wing aerodynamics, power management, and aircraft/engine performance.
If an aircraft is limited by temperature (T5, TOT, TGT, etc…Let’s call it T5 for now), will increasing rotor rpm by 2% (as is the case in many aircraft in “Cat A” mode) INCREASE or DECREASE T5 for a specific maneuver? (e.g. hover IGE, hover OGE, takeoff from a confined area, etc.)
Discussion: If you are temperature limited, ability to takeoff is in question, and you have a rather wide range of possible “normal” Nr, say 100%-107%, are you better off at a higher RPM or lower, and why?
