Flight model compared to Pakistani veteran accounts

[Dirty Rotten Flieger]

I'm happy to have another red plane to play with but the flight model is hopefully a work in progress :)

 

I found this great account of the Farmer from a pakistani veteran. He gives detailed descriptions of the handling. Here are some quotes I found interesting

 

 

Flying and fighting in the MiG-19: In conversation with Wg. Cdr. Irfan Masum (Rtd)

"“The F-86F had automatic leading edge slats, speed operated – a virtue not available to most other fighters around, not even the F-86E. That made the plane extremely manoeuvrable at low speeds. The MiG-19, on the other hand an aerodynamic problem where it would ‘adverse yaw’ at low speeds, often snapping out of hard turns during low speed manoeuvring. One had to assist a hard turn with a bit of inside rudder to keep it from ‘adverse yawing’. "...

 

...“There were quite a few bad qualities but the worst, in my opinion, was the thick wing which made transonic speeds (just short of Mach 1) very rough to ride through and almost uncontrollable, although it employed ‘short arm’ and ‘long arm’ technology to cater for it.”

 

...“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....

 

...During the very first merge, I was told by my section leader to do a hard 180 turn to the left. I remember going in to a hard turn and lighting my after burner. The next thing I remember is that is that the MiG flips out of the turn and starts spinning (this phenomenon was the result of adverse yaw attribute of the MiG-19)...

 

..."During one of the 1 Vs 1 combat training, I pulled vertically up without the afterburner. The airspeed bled so fast that before I could recover, my speed was approaching stalling speed. I knew fully well that if I allowed any yaw at the time of stalling, I will enter in a spin. So, I held my rudders neutral to avoid inducing any yaw. Also, I pushed the stick forward just enough to go to zero G – in a state of zero G the aircraft never stalls. Soon the speed went to zero and the MiG started sliding down while remaining in vertical position and the altimeter began to register a descent. I was thrilled that I was descending while in vertical position without stalling or spinning. My elation was rather short lived as I realised that I must recover without stalling or spinning. It was not possible to drop the nose forward or back words to the horizon. The only option was to yaw the MiG and let the nose drop sideways to the horizon. Mindful that if I induce a yaw the MiG will go in to a spin, I made sure that I maintained zero g (which does not allow the plane to stall) and induce a yaw just enough to let the nose drop sideway as done in a ‘Stall turn’ manoeuvre – which I had learnt in my basic training on the ‘Harvard the T-6G’. I also had to counter the roll that the yaw would induce by applying just enough opposite aileron. To my great delight and relief, the nose dropped sideways to the horizon and I could complete the recovery. The amazing thing was that the engines, which were very prone to stall, did not"

PS does anybody know what "Short arm and Long arm technology" is?

 

I saw the switch in the cockpit and wondered if it changes the sensitivity of the elevators as the speed increases or decreases. A similar system as the Mig21 has?

 

Maybe it is something else completely?

It is actually a similar system to the MiG-21's ARU system. It is located under the fat fin fillet by the way. Did not try it out yet but maybe one can even do the amazing stunts with arm in T.O./Lndg. mode like in the MiG-21.
