MasterZelgadis Posted October 22, 2010 Share Posted October 22, 2010 Hi pilots I have a problem right here, I discovered in the navigation Training mission, when the instructor said, I should set the throttle to around 80% fan speed to stabilize at around 300kias. Well, when I push my throttle (Saitek X52 Pro) all the way forward, I will end up with around 82% fan speed. Should it not be around 98% fan speed? I didn't touch any config about the throttle, saturation (X 100; Y 100) and curvature (0) set to default. Is there a way to configure my throttle to get the maximum of fan speed, and if yes, how can I do that? "Sieh nur, wie majestätisch du durch die Luft segelst. Wie ein Adler.

159th_Viper Posted October 22, 2010 Share Posted October 22, 2010 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.

MasterZelgadis Posted October 22, 2010 Author Share Posted October 22, 2010 I'm blind...I read it, but I didn't see that one. I should not go out there to hunt tanks ;) Thanks a lot "Sieh nur, wie majestätisch du durch die Luft segelst. Wie ein Adler.

MrYenko Posted October 23, 2010 Share Posted October 23, 2010 DCS: A-10C Beta Flight Manual, page 122 Engine Monitoring Instruments 3. Engine Fan Speed Indicators. Indication of rpm fan speed of each engine. Maximum, short term fan speed is 100% Normal operating range is 22 to 98% I'm an aircraft mechanic (DC-10s and MD-11s, [GE CF6-50 and -80 engines] mostly,) and although I'm not an engineer, and not familiar with TF34s or CF34s, I can say with 100% certainty that I've never, ever, not once, heard of a turbofan engine designed to run ~85% N1 with the power levers firewalled. That being said, and in a 100% supportive manner, I'd like to see ED's references on the current max-power settings in the sim. As it stands, I cant even get to 85% N1 most of the time, as it maxes out around 82-83%, even after disabling the joystick and using the keyboard to ensure I'm getting full power-lever movement. (I was, there was no change.) 80ish percent N1 sounds like the most efficient CRUISE power setting, but not full power. 1 Link to comment Share on other sites More sharing options...

For what its worth I am an A/C Engineer and fully agree with you :thumbup: 96% Max cont thrust. Take off approx 97% depending on Airfield temp, Alt and engine condition etc is a good ball park figure. Therefore 85% N1, firewalled can not be correct. 85% N2 for bleed air cross starts maybe?

rogueone Posted October 25, 2010 Share Posted October 25, 2010 Throttle question: my throttle command Joy_slider1 works and by changing assignments I can move either throttle 1 or throttle 2. However my joy_slider2 doesn't work to move either throttle 1 or throttle 2.

Rockeyes Posted October 25, 2010 Share Posted October 25, 2010 Doubt what you want matey but N1=Fan Speed N2= Core speed.:smartass: [sIGPIC][/sIGPIC] HTC Vive Windows 10 Maximus VIII Hero i7-6700k CPU @ 4.2GHz 16GB Nvida GeForce GTX 1080.

BlueRidgeDx Posted October 25, 2010 Share Posted October 25, 2010 N1 = fan speed? doubt it.. I'm not trying to get wrapped up in this, but I'm not sure what you're saying here? N1 is the abbreviation for Fan Speed; N2 is Core Speed. This is universal across turbojet/turbofan engines. ***Yes, before somebody says it, some RR engines are actually triple spooled and have N3, but that's irrelevant.*** "They've got us surrounded again - those poor bastards!" - Lt.

MrYenko Posted October 25, 2010 Share Posted October 25, 2010 ***Yes, before somebody says it, some RR engines are actually triple spooled and have N3, but that's irrelevant.*** RB211 'fo LYFE. :D The Russians built the Kuznetsov NK-12, which powers the TU-95 (Among others,) and is a really, REALLY impressive triple spool turboprop. The most powerful turboprop in the world, IIRC. It made 12,000hp in 1951. The A400M engines are also tri-spool. And there is another type of turbofan where the fan is indeed turning at a different (although directly proportional, the gearbox simply stepping down the fan speed to make a more fuel efficient airfoil on the fan blades possible) speed from either core spool; the geared turbofan.

Rockeyes Posted October 25, 2010 Share Posted October 25, 2010 Just found in a old Flight manual, Diagram A2-31 shows that it is possible to have a max N1 of 85% on this A/C. I stand corrected :doh: Well done DCS :worthy: [sIGPIC][/sIGPIC] HTC Vive Windows 10 Maximus VIII Hero i7-6700k CPU @ 4.2GHz 16GB Nvida GeForce GTX 1080.
