+lindr2 Posted December 22, 2008 Posted December 22, 2008 After oct patch ALL planes need to corrected FM & Engine tables... I found mach table info for F-14, F-5E, Jaguar engines. This info present in russian pilot manuals 198~ Era. http://1.airwar.z8.ru/bibl/f14book.zip http://1.airwar.z8.ru/bibl/f5ebook.zip http://1.airwar.z8.ru/bibl/jaguar.zip I used this info & update WET & DRY mach tables For F-14A: DryMachTableNumData=7 DryMachTableDeltaX=0.25 DryMachTableStartX=0.0 DryMachTableData=1.000,0.960,0.970,0.990,0.980,0.922,0.888 WetMachTableNumData=9 WetMachTableDeltaX=0.25 WetMachTableStartX=0.0 WetMachTableData=1.000,0.990,1.075,1.193,1.312,1.452,1.666,1.880,2.04 For F-5E DryMachTableNumData=8 DryMachTableDeltaX=0.25 DryMachTableStartX=0.0 DryMachTableData=1.000,0.897,0.862,0.875,0.897,0.966,1.010,1.142 WetMachTableNumData=8 WetMachTableDeltaX=0.25 WetMachTableStartX=0.0 WetMachTableData=1.000,0.923,0.954,1.054,1.227,1.455,1.659,1.955 For Jaguar DryMachTableNumData=7 DryMachTableDeltaX=0.25 DryMachTableStartX=0.0 DryMachTableData=1.000,0.875,0.75,0.666,0.583,0.666,0.708 WetMachTableNumData=7 WetMachTableDeltaX=0.25 WetMachTableStartX=0.0 WetMachTableData=1.000,0.907,0.895,0.974,1.04,1.237,1.368 MaxInletTemperature=140 Quote
Icarus999 Posted December 22, 2008 Posted December 22, 2008 This is Interesting,and very much needed. what do you guys think about having a sticky thread in the knowledge base where we can list the planes that need to have some attention given to their flight model for use with the new patch, so that C5 or another flight model guru can take a look at them. Some of my favorite aircraft do some funny things with the new patch. I was watching the AI fly the F-106 the other day and it looked like the jet was suspended by a string in its center .... the nose was pointing/jerking all over the place pretty funny stuff. A shame though because it was one of my favorites with the 8/06 patch. Quote
+Fubar512 Posted December 22, 2008 Posted December 22, 2008 Good call, though we have data from -1 and NATOPs manuals available to us. Also, 7-figure resolution is rather basic, as both Streakeagle (independent), and Kreelin (Mirage Factory), have produced dry and wet-Mach tables with upwards of 20-30 entries. That level of resolution can certainly be "felt" in a model's performance. Quote
+Fubar512 Posted December 22, 2008 Posted December 22, 2008 This example, is from the Mirage Factory's (Kreelin's) Tumansky R-13 series, and illustrates my point: AltitudeTableNumData=83 AltitudeTableDeltaX=303.8 AltitudeTableStartX=0.0 AltitudeTableData=0.9993,0.9642,0.9330,0.9046,0.8783,0.8535,0.8298,0.8070,0.7850,0.7637,0.7431,0.7233,0.7043,0.6862,0.6690,0.6528,0.6376,0.6233,0.6099,0.5975,0.5858,0.5748,0.5644,0.5545,0.5450,0.5357, 0.5265,0.5172,0.5079,0.4983,0.4884,0.4780,0.4673,0.4560,0.4442,0.4319,0.4191,0.4058,0.3920,0.3780,0.3636,0.3490,0.3343,0.3195,0.3048,0.2903,0.2760,0.2621,0.2485,0.2355,0.2229,0.2109,0.1995,0.1887,0.178 5,0.1689,0.1598,0.1512,0.1431,0.1354,0.1280,0.1208,0.1139,0.1071,0.1005,0.0939362,0.0873,0.08087,0.0744,0.0680,0.0617,0.0557,0.0499,0.0444,0.0392,0.0345,0.0302,0.0263,0.0225,0.0187,0.0144,0.0090,0.0017 ,0.000 DryMachTableNumData=25 DryMachTableDeltaX=0.05 DryMachTableStartX=0.0 DryMachTableData=1.0,1.0,1.0,1.0,1.0,1.0,1.0,1.0,1.0,1.0,1.0,1.0042,1.0080,1.0133,1.0205,1.0296,1.0410,1.000, 0.9713,0.6908,0.3134,0.1394,0.00,0.00,0.00 WetMachTableNumData=22 WetMachTableDeltaX=0.1 WetMachTableStartX=0.0 WetMachTableData=0.9842805,0.9915914,1.0004157,1.0029738,1.0092311,1.0103222,1.0560442,1.1012654,1.1314681,1.2330341,1.3844839,1.5556399,1.8760589,2.0332034,2.1909406,2.3390799,2.4647821,2.5867926,2.6 835739,2.756534,2.8496669,2.9270453 Quote

There are several sources, two of which I mentioned. To start with, there was (and there may still be) a rather interesting, free applet available from NASA, called "Enginesim", that allowed one to either create, or use an existing jet engine design, and produce altitude table graphs with literally dozens of entries.

Thank You very much ! , but I however want to know: I can get updated f14_data.ini, F5E_data.ini & ect. with '20-30 entries tables' ? Quote

They're MF birds, and they're either being worked on, or will be updated. I do have a '21MF FM, that I will upload, shortly. Quote
+krizis Posted December 22, 2008 Posted December 22, 2008 (edited) Here are typical R-15-300 engine data (Mig-25's, dry and wet thrusts vs mach at different altitudes). I'm working now to represent it in the game (to improve performance of the Mig-25). Both thrusts depend on altitude in very different ways, so it's quite difficult to close real and game's parameters. Moreover, the functions have discontinuities, so I think there is no need to have dozens of entries in each mach table - 10-12 will be enough in such case. Edited December 22, 2008 by krizis Quote
