Tf30 seems to generate more thrust than f110

[Ddg1500]

From at least 50 times of  experiences on f14A&B carrier landing, I found out that at about 85%rpm, tf30 seems to generate more thrust than f110 at nearly identical load at weight configurations, interesting  ………..

Wasn't there something about the TF30s having better thrust or some such at a very specific RPM and altitude combination?

That's when it's fast and not super high - the F110 is like a stroker and the TF30 is more like a peaky high-strung thing that benefits more from the ram air effect*.  Eg. at sea level, the F110 in full blower starts with about 23500 lbf installed at zero airspeed and gets up to 30500 lbf installed at mach 0.9, then tails off above that, whereas the TF30 starts out at about 17500 lbf installed at zero airspeed, peaks at the same 30500 lbf at mach 0.9, but doesn't tail off as quickly at higher speeds.  The higher you go, the bigger the gap becomes at low airspeeds (the F110 has dramatically better static suction) until "above 25000 feet and below 250 kias, all the TF30 does at mil power is turn JP5 into noise" as another once said.

 

 

*Unsure how much of this is the design of the engine itself (turbine compression stages and bypass and afterburner) versus the design of the variable ramp intakes and the tuning or lack thereof that the intake ramp schedule got for each engine, any intake ramp changes that happened down the line for maintainability and reliability, etc.

The above may be true but that's not what OP was talking about. In DCS, the TF-30s seem to have a substantially lower specific fuel consumption at low alt and intermediate power settings, which manifests itself in a much lower power setting required to maintain level flight. This is most pronounced in the stack. While the F110s sit at around 2700pph at max conserve speed (about 220-230kts), the TF-30s need only about 2000 pph. I've heard that the TF-30s indeed have lower SFC at low altitude but it seems exaggerated in DCS. One would have to check the performance charts though to confirm if that is indeed the case.
