BAe Sea Harrier - Technical data and discussion

This is also incorrect - the forward and downward thrust components are equal at 45 degrees nozzle angle providing overall more thrust then the engine makes static. And at 60 degrees it’s makes its peak thrust components

Good job on feet pics math

Math you didn’t even need to do as a diagram and thrust components data point was already provided.

The 28,000 and 14,000 figures hold up at 45 degrees nozzle angle not 60.

Even still the relatively low bleed rate is contributed also in part by the increased aerodynamic efficiency.

Don’t even say something about no full documentation.

Ive given you the full reference you can go and read the full thing.

Likely not true when compared to a CTVC harrier.

Given that the Cl of the harrier at heavy buffet is around .9 using only the wings standard aerodynamic lift coefficient.

As seen below there is a massive uptake of the lift coefficient here it appears to be close to an increase of 2.4.

Simply the added coefficient of lift proved by the change in airflow over the wing greatly exceeds the overall maximum lift coefficient achievable by the F-18

Buddy…look at your chart really closely.
The thrust at 0 degrees / no vectoring is 20,000lb.
The thrust at 60 degrees is 10,000lb.

10,000lb is half of 20,000lb.

Holy moly it’s a basic trigonometric problem. Wow. Amazing. Yet you somehow do not understand that.

Ohhh boy another unlabeled diagram from yet another different source and a conclusion based on conjecture. Note that no drag diagram is included… curious.

You can’t use this same excuse any more

The docs have been provided in full go read it and educate yourself

Maybe you ough to try reading them.

Just at a glance the chart you have posted already shows a non-vectored CL that is much higher than you claim it is. No Mach number is listed either.

It seems you are once again taking something out of context and then doing a song and dance go apply it to the Harrier.

Like does it ever stop?

Feet pic fails reading comp

That’s an AV-8B

I gave values for A

The simple explanation is that you have misinterpreted the document that describes the most efficient way to enter a turn.

I.E they are not slamming the nozzles to 60 degrees deflection and aren’t doing a pure-maximum ITR to enter a dogfight. This would also be consistent with other documents and practices described by pilots. For instance 20 degree deflection retains majority of forward thrust.

That’s literally what it says they are doing unless to you words don’t have meaning

50-60 degrees nozzle for a maximum performance turn missile brake

It was an example chart not exact data broski

The chart shows a CL of 1.5 for aerodynamic lift. Not the 0.9 you are claiming that it is.

Keep in mind I do have the NASA document that Gaijin has based the FM on as well. It’s not worth my effort since it should be blatantly apparent to anyone that you’re just going to keep moving goalposts to try to conjure and argument.

I already told you I gave data for harrier 1 that is a harrier 2

Harrier 1 is .9
Funny that the harrier 2 has almost as high a Cl as the Hornet

It’s almost like they entirely redesigned the wing to be a lot better. Crazy how that works.

Yet you still make the argument that somehow the Harrier II is incomparable to the Harrier I because it is somehow worse.

No we don’t have VIFF data for it as such no comparison can be made

The goal posts always move.

One day we can’t use the EM diagram for the Harrier II to generalize turn performance of Harrier I because it’s incomparable / worse / makes the plane look bad.

However we can use the CL diagram for Harrier II to try to approximate data for Harrier I on the next day because reasons.

Like dude just literally compare sea level diagram of Harrier II with diagrams for anything else at this point and you’ll see the plane is thoroughly mediocre.

All it showed was the CL increase due to thrust vector

Never claimed any specific data point just helped visualize the increase in lift C

Or you could just use the harrier 1 chart. Just an idea.

You have a Harrier 1 chart that shows bleed rate?
No?
I did not think so.

What?

If you angle the thrust down then not all of that thrust is pushing the plane forward. It is basic trigonometry.

No but it’s foolish to try compare it to the harrier 2 chart like you have been trying to do endlessly.

It’s extremely silly. The Harrier 1 chart shows the harrier 1 can sustain a full 6G at .8 Mach

The harrier 2 in that chart can’t even achieve .8 Mach in level flight.

Now you keep talking about the harrier 2 as being mediocre without taking 1 possible consideration into mind - what happens if a harrier 2 is using the normal lift thrust rating? What does the turn rate increase by then.

Seeing as the sustains G value on the harrier 1 was increased by over 1 in some cases. What’s to say seeing as they share the same engine and layout that the harrier 2 doesn’t achieve the same.

At 350 knots for example the Harrier 1 goes from sustaining 3.5G to sustaining 4.5G

What if the harrier 2 increased proportionally like the harrier 1?

3.8 to 4.8 at 350 knots if the added sustained G is the same as the harrier 1

So the harrier 2 goes from being mediocre to sustaining within 1 D/S with a clean F-16. Keep in minds that’s with all pylons and a gun pack. Vs the F-16 being clean, but only for this 1 given speed.

Regardless: We do not have any data to confirm the performance metrics of the Harrier 2 regarding normal lift thrust or CTVC

It’s such basic trigonometry that he got the angle wrong

Still at 45 degrees of nozzle angle the thrust going down and the thrust pointing aft are equal
