F16 vs F15c acceleration?

[falcon_120]

Hello all,

 

I would like to know how is the comparison in terms of better acceleration between the simulated version of the F15C in game and our simulated F16C. How do their T/W Ratio compare? Is there a clear winner or are we talking about small diferences dependent on altitude, fuel load, etc...

 

 

I don't want to generate any debate, and I'm just curious which one is supposed to do better in term of quickly accelarating from M0.8 to M1.2-M1.3 in order to give a amraam maximum performance and then crank away. I know that the eagle is overall the better BVR platform for many other reasons (better radar, endurance, loadout, ecm, etc...) but I was not sure if its also better in this specific scenario, given also that the F16 model simulated is a bit more modern over the F15C version simulated (am I wrong on this?) so maybe is packing more updated engines.

 

Since I suppose acceleration is different for different regimes and very dependent on loadout or altitude lets stick to this particular example:

Full fuel load and combat loadout (4 AIM120 + 4 sidewinder for the eagle or 4 Aim120 + 2 sidewinders for the viper, no bags for any of them), accelarating from M0.8 to around M1.2, altitude 20K (will it play a big factor?) which one of the is supposed to accelarate better in this specific context?

 

I know if we want to do it right we need to perfectly define the scenario, fuel load, altitude etc, what I'm looking is rather general guidance, just to be clear.

 

Thanks!

I think there's too much stuff WIP in the Viper right now to make a definitive statement.

Sorry I was not clear about that. I meant what we should expect regarding the RL fighter performance for the specific version that we have IN GAME.

 

I assume that eventually both FM will represent very close to RL performance (The F15C is already there). So there my question.

The F-15C has a few issues of it’s own in terms of mil/max acceleration rates. I ran some tests based on EM charts a while back, but I honestly don’t remember which direction they were off, just that they were off. I want to say mil was too slow and max AB was a little too fast.

I don't have the actual charts, but I think both aircraft are fairly close in this metric. Both aircraft like to fly at higher speeds and they have similar powerplants. The Eagle probably does better the more heavily loaded they are since weight will have less effect on it and its semi conformal MRM's should be lower drag.

The F-15 requires a lot more throttle than other aircraft outside of AB, so it wouldn't surprise me if mil thrust was a little low.

I've been able to do a max climb to 30,000 in the Viper without dropping below 300 knots. This is loaded with 6 120C's. I might make it to 28,000 in the Eagle with the same loadout before I drop below 300 knots. I'll start the climb after takeoff when I hit 500 knots CAS and then pitch up to 30-35 degrees on the ladder.

I've always thought the Eagle felt under powered in the time to climb metric. Both it and the Viper should have similar performance and they're both designed to be close to 1:1 TWR.

The Viper most definitely out accelerates the Eagle and has a much faster response to throttle movement. In fact it might even out perform the 29 but I haven't checked.

I would be willing to bet that it doesn't. Both in terms of acceleration and top speed the Mig-29 is a freaking monster, of course it chugs fuel faster than Frank the tank so....there's that.

 

Maybe if the fuel flow issue were fixed and we had an engine that performed at maximum power it might out accelerate it, but it certainly couldn't keep up with it in top speed

I suspect when the Viper starts being punished (as it should be) for the non-moving inlet, it'll have a little more trouble getting up there compared to the eagle.
