Energy Maneuverability

[JG14_Josf]

Thanks for the welcome back, Kurfürst, and it is encouraging to see that you continue to offer a well communicated viewpoint, and I hope that we can avoid repeating any irreconcilable contradictions that may have been generated in the past.

To which I will now attempt to communicate more information concerning the Energy Maneuverability angle of view generally and the corner velocity measure specifically.

To help broaden the scope of the data pool beyond those 2 charts that concern the 109E and the Spitfire, please consider helping in identifying the specific information being reported by utilizing the Navair Information and an additional example of the same type of EM Chart.

I can't (yet) cut and paste the Navair information other than text (no chart):

All that above may be GREEK to anyone sharing this interest in Accurately Measuring Relative Air Combat Performance.

RECAP:

Cornering Speed: "The lowest air speed at which a fighter can obtain the structural or aerodynamic limiting G force."

In the "dogfight" situation, this is the speed I'm trying to maintain in order to "out-turn" an adversary. It's also the speed above which I must excercise caution to prevent "Over-G" damage. Below this speed I must remain "Stall vigilant.

Is there a central location where the cornering speeds of CLoD aircraft can be found?

Obviously, to me, there is at least one other person who understands the significance of Corner Speed.

Please know the difference between Sustained Turn Performance and Accelerated or Instantaneous Turn Performance so as not to confuse the two.

Consider how much confusion might occur if someone were to confuse Accelerated or Instantaneous (Corner Speed) with Sustained Turn Performance with an example illustration.

Fighter A is dropping from a higher speed and higher altitude into the circle produced by Fighter B as Fighter B is maintaining or sustaining a level flight turn at Maximum Performance for a Sustained Turn.

Fighter A drops in behind Fighter B from higher altitude and higher speed, and the question that is asked will offer the reader an opportunity to test your understanding of Energy Maneuverability or Air Combat in general, to see if you are confused or not confused about the differences between Sustained Turn Performance and Instantaneous Turn Performance.

This is vital stuff, and if you are confused you may not even be able to recognize how vital this stuff is in fact.

Question:

Which plane will be able to turn a smaller turn radius and a faster turn rate when Plane A is dropping down into the turn of Plane B where Plane A is at Corner Velocity when it begins to track Plane B and where Plane B is maintaining a Sustained Turn at Maximum Sustained Turn Performance?

The answer must include a g force tolerance number for each pilot and so an arbitrary number can be added to the question so 5 g can suffice as the constant that is demanded in order to answer the question.

Plane A (Can be a Spitfire against Spitfire, 109 against 109, Spitfire against 109, Mig against Mig, F86 against F86, Mig against F86, Spitfire vs Mig, 109 vs Mig, etc.)

Plane B (can be any plane on those charts too)

Plane A is at the 5 g (pilot limited) Corner Speed at the time it dives into a tracking shot onto Plane B.

Plane B is flying a luffberry circle at Maximum Sustained Level Turn Performance Flight Path (Level turn at full throttle just above the stall or at CLMax angle of attack).

Which plane (Plane A or Plane B) in any case will turn inside which other plane when the assumption is that both pilots cannot tolerate more than 5 g?

Solve the question for 5 g as the pilot g limit - please.

Note: EM Charts can be made for each plane in the game by following the methods described in the Naviar link.
