GFD150 Posted March 30, 2015 Share Posted March 30, 2015 Would like to know how to increase engine power in the aircraft config file. The aircraft i want to increase power on is a A321-200. I'm having issues with only being able to climb at about 1000 ft a min and as low as 500 the higher i get and i'm not as cruise level. Thanks for the help everyone. Here is my general engine data for the aircraft in question. [generalenginedata] engine_type=1 fuel_flow_scalar=1.086 Engine.0=6.500000,-18.95,-5.125 Engine.1=6.500000,18.95,-5.125 min_throttle_limit=-0.43 max_contrail_temperature = -30 What numbers do i change? If someone could copy and paste in a reply some new numbers it would be greatly appreciated. Here are my autopilot settings for this aircraft as well. Anything that would help climb better would be a great help.

tvieno Posted March 30, 2015 Share Posted March 30, 2015 I'd check your weights and fuel quantities before mucking around with engine power. As poor as the A321 is modelled, it can fly and climb reasonably well right out of the box. http://my.flightmemory.com/pic/tvieno.gifhttp://www.vatsimsigs.co.uk/Status/1136602.jpg Link to comment Share on other sites More sharing options...
GFD150 Posted March 30, 2015 Author Share Posted March 30, 2015 All my weights are and fuel are fine. It's not a purchased aircraft it's a free download. Link to comment Share on other sites More sharing options...

Avechelice Posted March 30, 2015 Share Posted March 30, 2015 Hello, You can also try a very raw (but effective) setting .... [TurbineEngineData] fuel_flow_gain=0.00247 inlet_area=29.3000 If you increase the number the aircraft speed will be lower So in your case .. decrease this number ! Test some different values until satisfied .... BTW if it's the A321 from Project Airbus ... it's odd as mine is (after my setting) inlet_area=31.000//29.3000 And initial climb with no problems between 2.500 - 3.000 ft / minute Regards.http://smilies.sofrayt.com/%5E/a/bye.gif If you gave a couple of monkeys a box of ballpoints, enough paper, and enough time, they'd eventually finish up writing the complete works of Shakespeare :) Link to comment Share on other sites More sharing options...
GFD150 Posted March 31, 2015 Author Share Posted March 31, 2015 thanks. will be trying it out later on today. will let you know how it works. Link to comment Share on other sites More sharing options...
PhantomTweak Posted March 31, 2015 Share Posted March 31, 2015 If you really want to do it right, google a PDF file called jet_flow_chart.pdf at a place called Mudpond.org. I don't think I'm supposed to put that site up as a link, so that's the best I can offer. You will need a goof Air File Editor, like AirEd, available on this site as freeware. I've heard both pro's and con's about it, but I love it. Couple the PDF file and AirEd and you can make any jet engine as accurate as if it were real life. By the by, that Inlet_area tweak really only affects the aircraft's to end at it's optimum altitude, at 0 cargo/passenger weight and only 50% fuel. Give it a whole number change, set up a flight at whatever altitude (say 36,000, for example), 50%fuel, etc, give 'er full throttle and see what it maxes out at. It should wind up at about 5KIAS below the point where the OVERSPEED warning comes on (which number can be located in the aircraft.cfg file under [Reference Speeds]). If it's too fast, increase the whole number portion of the entry, try again. once you get real close, start changing the tenth's digit, then, if you want to get really accurate, the hundreth's. Remember, after every change, you have to reload the aircraft. If you do that, though, make certain AI traffic is totally OFF, or the the game may not read all the aircraft's file's. Hope all that helps a little! Pat☺ [sIGPIC][/sIGPIC] Had a thought...then there was the smell of something burning, and sparks, and then a big fire, and then the lights went out! I guess I better not do that again! Sgt, USMC, 10 years proud service, Inactive reserve now :D Link to comment Share on other sites More sharing options...
GFD150 Posted March 31, 2015 Author Share Posted March 31, 2015 Things are a tad bit better. i'm still only getting a total of 94.4 N1 and N2 power and if i try to climb past FL280 even with a climb of 500 FT per min. I lose my airspeed and have to stop the climb. Need to get full power. Link to comment Share on other sites More sharing options...
fsblibli Posted April 1, 2015 Share Posted April 1, 2015 Increase your autothrottle_max_rpm= 100.0. If found that on the Project Airbus it's even lower than 100%. I set it to around 107% and it helped. Otherwise the autopilot doesn't use full power on climb. Link to comment Share on other sites More sharing options...
napamule2 Posted April 1, 2015 Share Posted April 1, 2015 That's right. The 'old' setting for throttle rpm was '90.000'. I make mine '110.000'. Some modelers go by the SDK I am sure. But that don't mean it's correct (or rather it has been corrected but nobody 'heard' about it). Don't forget to turn on PITOT HEAT or you will have problems at altitude.
