SgtPappy Posted August 12, 2015 Posted August 12, 2015 I was wondering if anyone knew the source of these images: I'm interested in finding the Su-27's level flight acceleration (Mach number versus time) and was hoping the technical document that holds the above images might have that information. Thanks!
GGTharos Posted August 12, 2015 Posted August 12, 2015 The charts you're looking for are not publicly available AFAIK. The ones you posted here are from an RL combat manual [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda
Esac_mirmidon Posted August 12, 2015 Posted August 12, 2015 The only acceleration chart included in this document is: Acceleration from 600 Km/h to 1100 Km/h at 1.000 meters Su-27: 15 Sec - F-15: 13.5 Sec F-16A: 16 Sec - Tornado F2: 22 Sec.

SgtPappy Posted August 12, 2015 Author Posted August 12, 2015 Oh thanks so much for the info gentlemen. Hopefully more information will come to light sooner than later. The only acceleration chart included in this document is: Acceleration from 600 Km/h to 1100 Km/h at 1.000 meters Su-27: 15 Sec - F-15: 13.5 Sec F-16A: 16 Sec - Tornado F2: 22 Sec. mirmodon, would I be able to trouble you for that page? I'd like to have a screenshot of the diagram just to keep my documents consistent.

Ragnarok Posted August 12, 2015 Posted August 12, 2015 (edited) The only acceleration chart included in this document is: Acceleration from 600 Km/h to 1100 Km/h at 1.000 meters Su-27: 15 Sec - F-15: 13.5 Sec F-16A: 16 Sec - Tornado F2: 22 Sec. MiG-29S – 600-1100km/h to H=1km for 13,5s, 1100-1300km/h to H=11km for 8,7s, @SgtPappy, when I tested these charts, it seems to me that the su27 made by this chart. But you have to put 2.5t fuel. Also, F-15 does not match the chart, but the chart corresponds to the manual for the F-15 which shows the power of the engine. Maybe it's just a little stronger in the DCS, but not much... Keep Eagle with less then 3,5t fuel (less than of 8 on fuel meter) Edited August 12, 2015 by Ragnarok “The people will believe what the media tells them they believe.” — George Orwell

Ragnarok Posted August 12, 2015 Posted August 12, 2015 its for F-15A and F100-100. But PW-220 have 5% more thrust. “The people will believe what the media tells them they believe.” — George Orwell
SgtPappy Posted August 12, 2015 Author Posted August 12, 2015 Thanks Mirmidon! Ragnarok (And correct me if I'm wrong but this is what I think:) I think our F-15C might benefit from the upgraded thrust rating of the F100. The charts we referenced are pre-1988 and I think the F-15's engines were producing ~23770 lbf of thrust each, but after the F-15E came out, their engines (the same F100-PW-220's at the time) eventually were producing 25000 lbf of thrust. I don't know if they simply trimmed the engine or something, but you often see two different figures for the F-15's thrust. In DCS which is supposed to model modern F-15C's, this is probably the thrust we're working with, as you said, a 5% thrust increase.
