TheSkipjack95 Posted March 2, 2019 Share Posted March 2, 2019 Nice ! I did notice that taxiing needs a lot of care because of that spike in power output when going past 9000RPM, making careful throttle control a must. Hopefully those tweaks will make it easier. On the topic of spins, is it really impossible to make the Famer spin ? I've tried level flight + rudder, high attitude + rudder, botched turn reversal (which works in the hornet), but I only got to this state where it gently stalls, and yaw inputs bring the nose down, going into an alternating stall/recovery situation with the nose down and pro-spin controls applied.

RvETito Posted March 3, 2019 Share Posted March 3, 2019 Hi CaptSmiley, Thanks for the heads up, I have a couple of observations. The roll rate at subsonic speed seems really high but what I believe needs to be looked into are inertia and damping. At sea level both seem almost non existent as the a/c hits maximum roll rate almost immediately upon stick deflection but then when the stick is brought back to neutral the roll ceases almost instantly (high damping and no inertia). That behavior is typical for a FBW a/c like the F-16 for instance where the computer actually applies slight reverse roll command in order to match zero roll with neutral stick. At high alt the damping is decreasing as it should and it takes a bit of an opposite command to stop the roll but low in the weeds the MiG-19 has barely any competition. Hornets and Vipers beware! :) Drag in level flight - seems really low. At 12k m the a/c easily maintains Mach 1.01 at mil power with no stores and it takes at least 20 sec to slow down to Mach 0.9 after cutting engines to idle. Similar at sea level cutting engines to idle at 1000km/h IAS the a/c needs good 24-25 sec to slow down to 900km/h IAS in level flight. I've got the feeling that it's mostly due to low drag rather than high idle power. I would be interesting to read your thoughts on this. "See, to me that's a stupid instrument.

Random Posted March 3, 2019 Share Posted March 3, 2019 I have a question. Are engine thrust levels at speed / altitude something you have a source for? Or is it a matter of extrapolating from the acceleration curves? Link to comment Share on other sites More sharing options...

I was going to write a post that said exactly this, it feels like the aircraft is fly by wire but also at the same time has no drag.

Mumby Posted March 3, 2019 Share Posted March 3, 2019 Hi all, Thanks for all the hard work, i've got many hours of enjoyment out of your modules. What do the three axes represent in that plot, and what are the units? I'm not familiar with FM data analysis. Thanks Link to comment Share on other sites More sharing options...
schurem Posted March 3, 2019 Share Posted March 3, 2019 Very much looking forward to improved edge case modelling, such as stalls and spins. Make the beast a little more dangerous to handle. I5 9600KF, 32GB, 3080ti, G2, PointCTRL Link to comment Share on other sites More sharing options...
TLTeo Posted March 3, 2019 Share Posted March 3, 2019 Thanks for all the hard work, i've got many hours of enjoyment out of your modules. What do the three axes represent in that plot, and what are the units? I'm not familiar with FM data analysis. Thanks Judging from the legend and what people have reported, my gut feeling is that it represents level flight acceleration as a function of Mach number for different RPMs at a given aircraft weight. Given what people are saying about the jet, my guess is the dashed lines is what the FM "predicts", and the continuous ones what is actually happening - that is, the jet accelerates too well across the flight envelope (as confirmed by the points CptSmiley pointed out). Note that this is only speculation on my part and I do agree with you - plots without axis labels are a sin! Link to comment Share on other sites More sharing options...
Magot Posted March 3, 2019 Share Posted March 3, 2019 (edited) question: Mig-19 can't do it spin maneuver? I tried spin maneuver and plane never fall in spin. Here pilot Mig-19 describe how ecape from spin: https://hushkit.net/2017/10/30/flying-and-fighting-in-the-mig-19-in-conversation-with-wg-cdr-irfan-masum-part-1/ citate: “The MiG 19 was notorious for getting into spins without much warning due to it’s ‘adverse yaw’ attribute. And my most frightening episode also relates to this aspect. Is something completely wrong with Mig-19 FM? I' am in real glider pilot, so I know how enter in spin .. of course jet planes are differ but, this behaviour Mi-19P looks weird .. I know personally Mig-15 pilots and for example Mig-15 can do it spin only on one side (in direction of rotating engine) and Belsimtek do it correct on Mig-15. Count that Mig-19 have similar configuration .. so Mig-19 is two engined plane, engines have contra-rotating turbines if I' am correct, but when I OFF one engine, plane must go in spin in direction on this engine which is active.

ED Team m4ti140 Posted March 3, 2019 ED Team Share Posted March 3, 2019 What about lack of roll-yaw coupling? Is there some aerodynamic feature that explains this behaviour in this aircraft, or is this a bug Link to comment Share on other sites More sharing options...

rainyday Posted March 5, 2019 Share Posted March 5, 2019 Looking forwards to the FM improvements. It is really rewarding to fly a plane and learn it's 'happy place', when to push - and when to stop pushing or it will bite back. BUt I feel like MiG-19 is not quite there yet - feels a bit like beast that has been tamed. Glad to see all the dangerous stuff, quirks and other real plane issues is looked into to make the plane really 'come alive'.

rrohde Posted March 6, 2019 Share Posted March 6, 2019 That's great news. Automation is always a welcome addition to development I bet. I am sure the end-results will speak for themselves. Q: Will this tool also be used to go back and evaluate/refine the M200C and Harrier FMs?

Hummingbird Posted March 6, 2019 Share Posted March 6, 2019 Hi Cpt. Smiley, Biggest problem atm is that the aircraft doesn't want to lose speed at zero throttle, as if the aircraft experiences no drag at all. Hopefully this will be fixed soon?
