JAS-39E for Sweden

[DEV] JAS 39 GRIPEN E WRONG ENGINE

I think i found some information about the IRST should we need it, i don’t think it’s implemented on DEV yet so can’t check if it’s correct. I’m not sure if this information applies to the version “G” that is in JAS39E either.

IRST is implemented on Dev.

Are you in-game looking at the stock engine or the one when the engine module is unlocked?

when the engine module’s unlocked

Oh, i missed that in that case, i thought i cycled through all the options when i test flew it but apparently not :P

It’s usually the first thing I check with new additions, given my fondness for air to ground and the benefit being quiet brings to that.

Powerplant: 1 × General Electric F414-GE-39E (RM16) afterburning turbofan engine, 64 kN (14,400 lbf) thrust [349][d] dry, 98 kN (22,000 lbf) with afterburner

Powered by a single GE F414-GE39E afterburning tubofan offering 64 kN of thrust (98 kN with afterburner), the Gripen E has a maximum speed of 2,100 km/h at 15,240 m, a service ceiling of 52,000 ft (6,000 m), a combat range of 1,500 km and a ferry range of 4,000 km.

The in-game engines (all of them) also have less thrust than the numbers mentioned in all the specifications due to something called “channel loss”. When an engine is tested it’s on a testbench and get 100% of the air it needs to run, when installed in an aircraft the engine get less air due to the airflow being restricted by the intakes and things like that. So the DEV’s usually take away a percentage of thrust but i can’t remember the exact number.

Number varies quite considerably between platforms. Some of them are sod all, some of them are quite heavily impacted.

But it is lost too much, based on sources E should be faster like 20% than C

If they manage to get the IRL numbers i think they add those, otherwise they just do some percentage but i’m not sure if they do the same for every aircraft. In this case (if all modules are indeed unlocked and the report is correct) it looks to be ~19%.

Edit:
I think they haven’t changed the characteristics of the engine yet, it looks like it’s still the C engine numbers:

My pict in report is after engine module unlocked

your edit is about what I said in report lol. that’s why I reported that thing

They dont. For the most part they apply 10% channel loss I think but with some vehicles it might be more or less depending on sources provided.

But i think the actual engine gives more thrust and it’s just the stat card number stat are wrong, when i flew it an hour ago it could supercruise at sea level. Something the C can’t do. I’m uncertain about this though.

C can super cruise at sea level

yeah, you should read my report in above link

Were you carrying any ordinance? Because clean Gripen C can already supercruise at sea level:

Yeah you’re all correct, both planes top out at Mach 1.03 when flown clean and 15 min fuel. So still C version engine on the E i’m guessing.
