Unreal pitch change

[yufighter]

In borderline positive G load after restoring the control stick in neutral position leads to unrealistic changes PITCH, which is not in accordance with the laws of physics.

This is evident in the following times of 14:52:12, 14:53:18, 14:53:17, 14:56:07 video.

You may want to change the link for the vid, it isn't working

Just use the video code as opposed to the whole youtube link. You know, the text behind the "="

Here's the video:

Without detailed aerodynamic data it's difficult to tell if that behavior is wrong or right. What you'd need is the pitch inertia and pitching moment at that elevator placement at that Mach swept over those AOA. I agree it looks overly sharp.

 

We could make a very rough investigation using tail area as a flat board like a bar room dart and an assumed moment of inertia. The CP shift on the main wings I fear makes a large impact on the pitch moment that I don't know how to begin approximating.

I have enclosed * .trk file the summer that can be analyzed in detail and notice this anomaly.

Also in the video footage shows that RPM value shown is incorrect. The engine operated with 100%, and it is shown that the RPM is 50%.

yufighter, what are you trying to accomplish here?

 

Dolphin has already repsonded to you on LN's bug tracker, on the bug report you created.

In this video, unlike the previous, showing the behavior of the aircraft and still in the same maneuver but in a horizontal plane. The purpose of this video is a more detailed view of the problems that I have outlined. I hope you now understand what I want.

 

Sorry for the bad English.
