Harrier Overheating Problem

Alas, this is not a conspiracy theory. There are just plenty of similar examples in the British tech tree.

If you’re talking about the AV-8B, it’s an excellent aircraft, and it’s nothing like the original Harrier in the game.

They used the AV-8A and C too

Weren’t they introduced into the game later as a copy-paste of the British Harrier?

The Av-8A and C, and the Harrier Gr.1 and Gr.3 were all introduced in New Power.

Those are not top speed charts for sustained speed, that’s maximum safe speed for engine operation.

@Flogger_cbs
Harrier’s a joint US-Britain project, and we all know Gaijin loves USA and Britain.

And AV-8A/C use different engines.

Max speed on the deck is 614.64kt

With minimal remaining fuel, it is possible to accelerate up to 627 knots.

You can see they can go or not from this website.

Okay, it’s just that I tried to do it in the test flight.

That’s max speed wisla the harrier doesn’t actually have airspeed limits.

The level flight envelope in the av-8a manual is for max thrust setting or 16,000 lbs the Pegasus can make 19,000 lbs + in normal lift setting. Therefore the aircraft can actually accelerate past the envelope given in the manual to the 625 listed.

In the Gr1 pilots notes it clearly states there is no IAS limit so in game you should be able to put it in a vertical dive from max altitude and not even worry about it breaking.

In game it’s not

I’ve bug reported lots of harrier issues they don’t get fixed.

You posted documentation showing IAS limits of the engine.

As for thrust:
16458 / 2.20462 = 7465kgf.
13197 / 2.20462 = 5986kgf.

Spoiler



9218 x 2.20462 = 20,322lbf.

Engine thrust is either correct or over-performing, either way it’s not under-performing.

It showed 1g flight envelope and was also done in 1968 the harrier 1 is a transonic fighter and like the hunter should be able to slip in and out of supersonic speeds easily with just shallow dives.

I have also reported on the thrust of the Pegasus the mk101 and 401 over perform at low end thrust however the later Pegasus engines underperform in low end thrust.

Nonetheless I want you to measure thrust at .7 Mach at sea level and notice how it drops by about 50% they artificially nerfed the harrier on release by having its thrust decrease with speed yet irl it doesn’t. This means zoom climbs, str, max achievable alt, and acceleration where all falsely nerfed since it entered the game.

Aircraft have specific speeds for maximum thrust, Harriers are closer to 0 IAS.
F-14B gets to peak thrust around 900IAS.

IRL the Pegasus engine increases thrust with airspeed.


I’ve also gone through the gross thrust chart and calculated in ram drag for various Mach functions and it still results in a net increase in thrust. Even at transonic speeds.

In game we can see it drop off in thrust rapidly. All jet engines make more power with increased free stream velocity.

Gaijin nerfed it like this as they didn’t understand how the performance charts were made.

As you demonstrated above with 85% throttle or so the Harrier Gr.1 and AV-8A should perform in climb and speed what they do with WEP in game.


As seen here for a clean aircraft with 85% throttle in game the AV-8A should be able to cruise at 40,100 feet and have a combat ceiling of 46,100 feet with 500 FPM climb remaining. Good luck even getting to 40 grand in a harrier.

With missiles and guns retained and with 3,100 lbs of fuel the AV-8A will climb at 16,700 FPM and in game should do that with 85% throttle.

40,000 feet is easy to do in all Harriers.

Never said it wasn’t Alvis but it will barely do it the highest I’ve ever gotten the Gr.3 was around 42k and that was max achieved to the stall while also using 110% throttle.

With guns and missiles it should get to 43k with 85% throttle.

So how high can you get the AV-8A at 85% throttle with guns and 2 sidewinders retained on the plane?

That would be with 5000 lbs plus of fuel on the combat air patrol.

When at combat weight with 3,100 lbs fuel remaining it will do the 43k
