stelios2000 Posted June 26, 2012 Posted June 26, 2012 Hi all, I have Saitek X52 and it was great in every sim....till A-10C. I cant make the engines go up to 100%.... they lock 82-83% every time in the game (at the throttle the are at the top end). I chose OPTIONS/AXES and then BOTH ENGINES "found" the throttle but same again no more than 82%. Can somebody please help me? thanks in advance stelios

Pyroflash Posted June 26, 2012 Posted June 26, 2012 Yes, the FAN RPM simply shows the RPM of the fan section at the front of the turbofan assembly. It produces max thrust at around 82% under nominal conditions. There should be another gauge that shows core RPM, and this will give you a pretty good indication of your engine's actual RPM. This gauge will max out at 100% in most conditions, though it is important to monitor that it does not go too high. If you aim for the sky, you will never hit the ground.
sobek Posted June 26, 2012 Posted June 26, 2012 Yes, this is as per specification. It seems that the TF34s in the A-10 are somewhat rated down to improve their efficiency/durability, that's why the fan maxes out at around 82%. Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!
GregP Posted June 26, 2012 Posted June 26, 2012 Also noted in the A-10C FAQ: http://forums.eagle.ru/showthread.php?t=67747 "Q: FAN RPM % does not exceed 82%. Is something wrong with my throttle? A: No. The engine is designed to operate at optimum performance, which is 82% FAN RPM. Also note, that there is a difference between Core RPM and FAN RPM."
stelios2000 Posted June 26, 2012 Author Posted June 26, 2012 Thank you guys for the quick answers... I am pretty sure though that when i bought the game in some Instant missions the FAN gauges went at 100%......I remember it vividly.... but if you say so......then i might get old enough (36) ...... anyway.... thanks again stelios
chief Posted June 26, 2012 Posted June 26, 2012 I thought this was weird too. We have the cfm56 engines on our plane. We can easily get the fans up to 100%. Wonder what makes these 34s do this.

For example in a steep dive the Fan might start reaching higher RPM's due to windmilling. Or better said, it reaches higher RPM's because the airflow that's coming in is doing so at an higher speed then usual causing less resistance. I thought this was weird too. We have the cfm56 engines on our plane. We can easily get the fans up to 100%. Wonder what makes these 34s do this. As said earlyer in the thread, the A10C's engines are downrated to improve durability/reliability. Causing a max Fan RPM of ~ 82% under normal conditions. PS, there is a thread around here discussing this game feature (as it turned out to be) in detail. ~S~ [sIGPIC][/sIGPIC] The keeper of all mathematical knowledge and the oracle of flight modeling.:)

gear_monkey Posted June 27, 2012 Posted June 27, 2012 these are all just relative numbers anyway...each engine manufacturer has their own concept of what "100%" is. If a particular motor rates max thrust at 82% N1 or "fan" then so be it. one of the corporate jets I flew had a recommended take-off and max cruise setting of 101.4%. the E-120 Brasilia I flew for the airlines could obtain up to 160% torque... I've always thought...how can you have more than 100% of anything?? it's all ball bearings these days boys.....

I remember reading the engines are dereated to improve their service life... But for the life of me I cannot find the reference. The CFM-56 Was developed for the commercial industry and might have something to do with the difference... However, If you ask one of your pilots, (KC-135 Right?) They will tell you they seldom use 100% N1. They maximize takeoff data based on runway available...Flap setting...Temp & Pressure altitude etc, so the can use less engine to get airborne and have thrust available in an emergency if something happens.
