BAe Sea Harrier - Technical data and discussion

They say all this but Art Nalls has said if you set it up right you can let go of the stick in the sea harrier and it will remain stationary.

Yeah, I knew it was something for those who know little of aircraft but I enjoy when my favourite aircraft still get mentioned properly instead of getting dismissed because its subsonic and has a useful feature

Well yes, but this would be more AV-8B harrier 2 related.

All misrepresented in every simulator and game. I feel we will get more information about them as sundown comes around.

Made a 20,000 feet comparative performance chart for the data I have on the Gr.1 (RR400 - mk101 engine) Harrier

This performance would be so nice for the FA.2.

The harriers engine has a PRL that limits the rpm of the engine under certain conditions to make the engine surge free under harsh flight conditions.

When developing the FA.2 they decided to re-define the PRL and it was over-restrictive. They found that turn performance could be improved 50-100% while still maintaining the surge free AOA limits.

Do / would the devs consider real life HUD videos as a useable source?

This awesome FA.2 at an airshow estimated to be at 17,900 lbs with 2 190 gallon tanks will pull 5.1G /10 degrees AOA at 427 knots.

Really running out of ideas, would be hilarious if video of the actual IRL plane pulling the G claimed in the docs is not enough proof.


Gaijins FA.2 at the same estimated weight with 2 rocket pods will pull 4.1G/10 degrees AOA at 422 knots.

369 knots IRL 3.8G 9 degrees AOA

Gaijin - 3G

Hello

After several videos that were reported and misinterpreted either intentionally unintentionally over the past year or so for some top tier jets, such videos are no longer accepted, partially because:

It is based on guesswork and interpreted from the person reporting it. Rather than the factual based information coming from the manuals and other primary documents that the FM is currently based upon. So a video would not supersede this.

I see that’s perfectly understandable.

I do however have a report from BAE systems about the sea harrier maneuvering performance in this exact configuration when loaded up to 22,000 lbs.

Again I would just like to point out - according to BAE a 22,000 lbs aircraft will pull similar G at the same AOA as the source gaijin used to model the lift. That source used a 17,000 lbs aircraft. 5,000 lbs less weight to still achieve less - the same G.

Gaijin also didn’t fully read the flight V-N diagram.

1 it uses cockpit units AOA (this is an unknown quantity as the harrier actually uses an airstream direction detector that gives units equivalent to real AOA)

2 the V-N diagram gaijin used does not includes stall boundaries (stall boundaries are found in other aircraft’s V-N diagrams like the F-4)


In the very manual the devs used there includes another chart that confirms my initial report.
7.5G seen at .65 Mach at the deep buffet (maximum usable Lift coefficient) AOA on a 16,500 lbs harrier 1. This would be approximately 14 degrees AOA/ADD read on the HUD and AOA indicator on the real aircraft.

Was it the Rafale reports?

Probably one of them

Goofy, ahh well we have something they don’t have.

A direct report from BAE in the exact profile at an exact weight including the AOA per G.

Unless this is not a valid source. We still have gaijins own source to use as it includes the correct lift chart, but maybe that’s not valid either.

Stall AOA and Cl data for anyone who’s curious.

The Harriers wing was one of the most advanced aerodynamic profiles of its time. They had to make a wing that provided 6G lift at 400 knots at 10,000 feet that remained within the size and weight requirements.



So @Smin1080p_WT

Could you possibly ask the devs to reconsider.

The devs denied the report based on a chart from the AV-8A manual, a chart they didn’t read fully.

In the exact same manual there includes another chart that has the correct maximum lift performance.

So in their own document there is a chart that confirms my report.

We even have the coefficient of lift that the devs need to use to correct the performance.


As already explained several times, all of this information has already been reviewed. Unless there is brand new source material, the outcome will remain as its based on primary documentation.

Is this some kind joke now.

Operating data manual - CA release to service - nasa technical reports - BAE maneuvering performance report - THE ACTUAL PRIMARY DOCUMENT THEY USED

All 5 documents undeniably confirm my initial report.

This is from the same document, the exact same manual they used.

How is it less primary when it’s the same thing.

The AV-8A manual is less primary than the AV-8A manual according to the devs

@Gunjob
Could you please talk to the devs. I think 5 primary sources including the source the devs used should be more then enough.

To play devils advocate: 7.5g in that diagram is the structural limit, it is not saying the aircraft is actually capable of pulling that many g.

Not quite there is another chart for that.

Flight strength diagram is a composite presentation of the airplanes operating envelope.
It represents pulling the wing until stall AOA. This angle varies based on Mach number.
