F-15 Eagle: History, Performance & Discussion

Unless there is a source saying gaijin is right about engine channel loss then it should be lowered to the level of other jets regardless

You must realize that duct losses are pressure losses, not thrust losses. Of course there are graphs that show the relative thrust losses in the air intake duct and nozzle

Sure, but should the F-15 specifically really have this much loss? If they are taking liberties with all the other jets they should take liberties with the F-15’s as well

Compare the F-15 with the existing acceleration, climb, and turn schedules.

Gaijin has engine installed thrust data for the F-15A/C, I am not sure about the F-15E. The intake losses are accounted for on the F-15 series properly… they have chosen to improperly model the Su-27, it is “good enough” for them at the moment. The higher thrust is not the advantage you think it is. It comes with increased drag and low SEP.

So this pretty much means that gaijin doesn’t know how to properly model other planes and the F-15s are accurately modeled.

Most American stuff aside from the F-16 is modeled pretty well given the game engine limitations. The Su-27 and MiG-29 lack the easy to read and simplistic EM diagrams of western aircraft and thus are poorly modeled.

No. The only restriction is the -220 jets cannot share CFTs with -229 jets due to some differences in how the heat exchangers work. They get swapped around like candy otherwise.

did anyone try bug report this? would be very big if added as 13.0 is pretty rough right now

Honestly if gaijin solidifies their position on the Kh-38MT then there could be a genuine argument to have that added

isnt HMD on f4j from an experimental one like that?

Maybe, but less experimental than Agile Eye afaik

I think you mean overpreforming inlets as gaijin chose to give it functionally no channel loss.

Reminder as well that channel loss to gaijin is fully arbitrary with engines that lack a channel full stop like the TF34 having channel loss for some ungodly reason.

Not just all planes, anything that flies, missiles, helos, bullets planes etc, gaijin’s drag simulation is horrible and needs a refactor.

Such came to light with the AIM-54 being unable to ever reach it’s designed max speed even if fired from orbit straight down.

It is presented in manual for F-4J and in SAC sheet for F-4S.

It depends which HMS specifically you are referring to VTAS-I ( baseline AN/APG-8, system produced by McDonnell-Douglas mounted to the AN/HGU-30/P, Ersatz modified APH-6 with COTS liner, Later the -30A/P which uses a Molded liner (Pilot comfort and improved fit) was introduced) and saw frontline service starting with the Block 46 & -47 F-4J airframes, though not available in quantity until 1972.

The VTAS -II ( AN/APG-8A uses an improved Display and was produced by Honeywell, mounted to the HGU-37, which uses a PRK-42/P shell)


Further Select F-15A & -15B airframes, alongside F-14As & A-7s (mass simulators were also flown on the F-5E) that were used during ACE/AIMVAL, to help provide feedback to the Seeker trials that were undertaken, and so were fitted with revised VTAS II & prototype VTAS -III sets for comparison and testing purposes.

Studies were performed for mounting it to the F-16 as well

The VTAS was never fitted in service to any Teen series aircraft due to not being able to loose the weight needed to be deemed safe for (sustained) use at the higher 7.5~9G’s that the Teen Series were rated for vs the F-4’s 7.5G, without causing strain issues or injury to pilots, while still meeting Ballistic Protection requirements of a flight helmet so was not procured, and canceled due to delays and not being able to satisfactorily meet the design requirements or goals.

When it comes to channel loss ingame, unless Gaijin specifically has data for it they just… make it up. Then they change the drag to match acceleration charts and turn etc. Really, the channel loss doesn’t matter. So the F-15A/C having 22 percent percent channel loss and the E like 19 percent doesn’t matter, it’s just a funny stat
