Wilco Harrier (Download version released!)

Smoke intake effect by Jason Morgan

While waiting for the Zsolt repaints to be cleared by the flightsim staff (not there yet!) (edit: yes it is!), there is a nice Yeovilton [SIZE=-1]Sea Harrier [/SIZE]repaint by Jason Morgan already available. And it includes a nice intake smoke effect.

I've added an Auto_Smoke.xml gauge to make this effect appears only when N1 thrust is more than 50% and airspeed less than 80 knots... Plenty of room for improvement! Sorry for the GIF image... This forum doesn't like xml gauge reverse polish notation... who does...

Add this xml file inside a subfolder of the panel folder (I called mine "HarInt"). And in the panel.cfg add this to the [Vcockpit01] section :
gauge07=HarInt!Auto_Smoke, 0,0

Don't forget to update the aircraft.cfg file. Follow Jason's indications in his readme file.

Thanks to Jason Morgan for repaint and effect!
Thanks to Simon Swallow for his HMS Ark Royal for FSX at EGHI (porthigh.zip at flightsim)

It's not smoke, the Harrier family have a tank of de-mineralised water that gets injected into the front of the engine to increase the power for take-off/landing, so what you're seeing is the water vapour.

I have no idea how it works, although I think it's supposed to lower the intake air temperature so you can achieve full thrust without exceeding the max ITT on a hot day.

Yes, you are right about the last statement :icon_lol:
I suggest not to use this Autosmoke gauge as-is, since it induces the infamous "continuous event" problem; causing multi-keystroke commands, like pushback heading select, engine-select, exit select, radio select, etc etc., not to work properly.
Not very apperant here, since this Harrier has only one engine and one exit.
But if you try "N" followed by "2" to select the second NAV radio: it won't work anymore.

Iow:
Code: 
  if{ (>K:SMOKE_ON) } els{ (>K:SMOKE_OFF) }
is wrong coding, because it continuously generates either a SmokeOn or SmokeOff event.

Proper code would be:
Code: 
 if{ (A:SMOKE ENABLE,bool) ! if{ (>K:SMOKE_ON) } }
 els{ (A:SMOKE ENABLE,bool) if{ (>K:SMOKE_OFF) } }
I'm sure you see the difference: an event is now only given when the state of the Smokesystem var doesn't match the condition.

So in general: allways test first if it's necessary to give an event (ie. only give it if the related var is in the wrong state).
Can be applied to ANY event (even axis events).
Hope that helps ....

Hi Sven,

The hydraulics are cured by navigating to the [Hydraulics] section in the Aircraft CFG.

and using this value:

normal_pressure=3000.000000

During all the to and fro of editing FDs, the poor old thing lost all its hydraulics!

The collimation is being revised for the HUD so things will change there.:engel016:

Hello Barry,

Been away for a few days but this is excellent news! Looking forward to the update. The flight characteristics are very believable, based on my very short experience in a simulator.

Very close Skippy, firstly it is not smoke and yes it is water vapour caused by the slow moving air entering from the aux air intakes meeting the faster heated air entering directly into the intakes (basically stalling air).

Harriers carry 50gallons of Demineralised water in a tank just behind the engine and between the hot nozzles, which takes 90s to use. It gives up to ~2,000lb increase in thrust in the right circumstances (nearly 10%) - which in vertical operations can make all the difference between hovering and not, or getting off a short strip, Nominally 30s for takeoff, and 60s for landing (it doesn't start flowing until triggered as a certain JPT reached).

Injected after the combustion chamber, but before the free power turbines. With water flowing, you get a slight increase in allowable RPM and JPT, but of course, a great increase in "effective JPT" (i.e. for a certain fuel flow and RPM, water reduces the JPT, AND you get a higher limit).

Ahhhh! So that's how it works! I remember a sunny afternoon on BOST where one of the AETs asked how it worked for one of his exams. Bit of a stretch for a Lynx flight to be honest...
 
I still cannot find the speed brake indicator or the pitot heater. If either does not exist then what can I edit to have the pitot always on?
Having a blast with the plane. My fav is to be in a hover at the lowest altitude you can get away with. Then pitch the nose up and slowly reduce the nozzles and begin to pitch up. I have stood it on its tail doing this. Then eventually climb out vertical and watch later via tower view.
Btw- I was in aviation for the most part of my early years till my 40s and been around most all planes. I agree that the Harrier is the loudest with the B1-B a close second. The most damaging that headgear had no effect on was the t-37 tweet. Its whistle cut right through them and is probably why I have a 20 plus% loss of upper freqs in both ears.

Yes that low altitude bit, is the where the VTOL gauge doesn't quite cut it, one you get close to the ground the recirculating air moving under the wing should cause quite a sever suck down, which is why the Harrier gear had such a long stroke to absorb that final drop.

Saw several demonstrations of that vertical ascent maneuver, a wonderfully noisy affair.

We had 'temporary' (read cheap) meeting rooms which were little more than wooden sheds adjacent to the runway at Dunsfold, on many occasions meetings would be held up waiting for a hovering Harrier to move away so you could actually have a discussion.
 
The USMC Harriers based at Beaufort MCAS on the coast rarely venture up to central SC. I was flying freight in a Turbo Commander 690 and just flipped over to tower freq. 2 Harriers were in slow flight 1/2 mile off the threshhold and the tower ask them if they were going to hover. Seeing a military jet flying that slow is odd and from the air is downright freaky. I could not hear their reply on my comms but got the impression they were just going to do a low fly by. The pair started to descend to maybe 300 agl or so and again she ask if they were going to hover and said with a stern voice,"Do not hover". Well I was downwind and got a good look at one of them accelerate and do a low pass but the other dissapeared in a cloud of dust and landed about 1000 ft down the runway. She then got on his case about it. I had to extend, he did a stol, headed south and became a dot. I was then told the runway was fouled and to land on the second runway. I was later told the harrier baked and burned the surface. The FD had to hose off the debri and from what I understand the pilot was reprimanded. Other than airshows thats the only story I have about the Harrier. I know from other pilots that there are stretches of interstate and rural roads that are designated for both the Harriers and other fixed wing to use both for emergency and combat ops. Locals in Beaufort have seen the harriers covered in camo off secondary roads and in barns during practice and war games.
 
Is a final updated version available for this yet or still awaiting it? (enjoying it as is but would like to have the latest version installed when available)

Matt
 
Should be very soon Matt, we have just uploaded it.

Speedbrake control, parkbrake and pitot switch are among the revisions and fall easily to hand.

Hello bazzar,
Thanks for the update! I presume it is the "HJJ_FSX_v2.exe" file, isn´t it?
I´m asking because there is now two installers available and i don´t know witch one is the new one:
Harrier Jump Jet - HJJ FSX
Other files:
HJJ FSX v10
HJJ FSX v2

Thanks! :salute:
 
My install is failing. After entering the serial numbers it begins the install but halts ans I get a error message. Something about missing textures form a sea harrier exterior mdl or what not. Unable to install completly.Invalid data Aborted.Error Mfd. Try again. Have a nice day. No Harrier v2 for you.
