Adjusting wing loading?

[KJakker]

I recently was thinking about the F-100 in comparison to the MIG-19 and was wondering how to go about adjusting the wing loading of the F-100 to simulate equipping it with larger wings of 468 square feet vs. the original 400 square feet? According to my numbers that would give the F-100 near identical wing loading to the MIG-19. I want to try and figure out what would have been necessary to make "the Hun" the equal of the mig-19 in a dogfight. The other issue if T/W ratio I think I have solved.

Personally, I wouldn't change it. The F-100 isn't the equal of the Mig-19 in a dogfight. Even so, I 've been able to bring down Mig-19s on regular basis in the Hun. Last night, I dropped 4xMig-17s in the F-100 (Normal enemy skill), and the '17 is an even better turn-n-burner than the Mig-19. Granted, my '17s have slightly tweeked FMs - and I seriously mean "slightly" because I fly and fight (VERY successfuly) in the same '17 too.

 

My point being, you can successfully dogfight in the Hun the way it is. Just remember to keep your speed high and never, never forget to use your rudder in the turns. I also get a lot of kills in the F-100 by bringing the fight down close to the ground ( close enough to pick some mangos ) where the AI is unwilling to maneuver as hard as they usually do.

Thanks for the reply. This is just an experiment not something I would use in a campaign. It is more a what if new wings had been fitted and the aircraft re-engined test scenario than anything else. Incidentally I found where the wing loading in my F-100Ex_data.ini file is located.

Oops! There I go rambling off again. Sorry about that. Glad you found what you needed. Hope you have fun with it!

There is no "wing loading value", per se. Flight models consist of a complex interrelationship between the various lifting surfaces, control surfaces, and inertia values.

 

The AI-only aircraft in this series (such as the aforementioned MiG-19) are not coded to be player-flyable, as they are simplified for the AI's benefit. In fact, they do not fly under the same conditions that the player does...the game engine allows them to use an easier dynamics model...notice that the AI-pilots don't suffer from G-lock.

 

The only AI-aircraft which are somewhat accurate, are the MiG-21 models. And even there, quite a few compromises were made to keep them AI-friendly (stall, lift, and drag values, throttle rates, control-surface deflection angles and actuation rates, etc).

 

FastCargo is compiling a wiki on flight-dynamics, and I'm sure that you'll find it helpful.

 

For now, I suggest that you do nothing more than add 5-10% to the CLa values for the the four wing panels on the 'Hun.

The only thing I have ajusted so far is the "ReferenceArea" and the "EmptyMass" to account for the differences in wing area and engine weight. I still need to fine out what the average mass of the F-100's wings are so I can properly adjust the aircraft mass to account for the larger wings though. Thanks for the info about about FastCargo 's flight-dynamics wiki. I will have to keep an eye out for that.

Reference area appears to only come into play post-stall. Empty mass will effect the FM in all three axises, including the z-axis....I wouldn't do that if I were you.

I will reset those on my F-100 experimental. What would be great would be a spread sheet that I could plug that data into that would automatically adjust everything in the FM according each individual change. Still just re-engining the plane with an F100-PW-200 in place of the J57 does wonder for its performance.
