Lockheed Jetstar II

Jetstar in PBR4

I took a quick course in PBR conversion and this is the results. I sent Roland a PBR4 version file and will let him decide if he wants to upload here or where ever.

Jetstar II - preliminary paint kit & white texture

I just uploaded - never done this, hope it works!

OK - looks like it did!!

I am no pro, but getting there with layering in Photoshop PSD files. I would like to point out to those wo do not already know, a couple of successful approaches to adding a texture to my white base files.

1. Create new blank layers(s) to paint on ABOVE the basic layers provided

2. once done painting in what you want, right click on individual new layer(s) and choose "blending options"

3. choose "blending mode" - multiply

If your new layer is on top of the basic layers, this should pick up the detail from the layers below it, rather than painting over the detail and obscuring it beneath the areas where you painted.

I have layers for dummy registration numbers on the outboard engines - these are text layers that can be completely edited in style, size and color using the text tool

I hope this is a quick start that will be a gradually improved set of products.

Now working on a metal texture, but will take a little time to smooth up

Looking forward to your comments and suggestions.

GE - those PBR shots look fantastic - very impressed.

Mike71 - Though I don't have photoshop your efforts are much appreciated, now opening the door to others doing some further repaints hopefully.

Thanks guys!
 
Thanks a lot Mike- VERY appreciated

Whats next ?

FSX:I will repair some more gauges, and make next model ( Beta2 ) available und upoad here
Also incluse all the findings

P3D only:I will do like above and add GREY EAGLE'S PBR model ( THANK YOU SO MUCH )+ texture as well

Still we need XML gauges makers, Repainters (N313JS), GMAX Artist (VC) to move further more forward


Thanks to all contributors

Roland

Allow overwrite


in panel cfg / [Vcockpit01] you replace this


gauge24=JS!JET_ITT_1, 629,133,37,39
gauge25=JS!JET_ITT_2, 675,133,37,39
gauge26=JS!JET_ITT_3, 722,133,37,39
gauge27=JS!JET_ITT_3, 768,133,37,39

and this

gauge72=LJS!Jet_FF_1, 1352,355,68,68
gauge73=LJS!Jet_FF_4, 1540,355,70,70

and this

gauge144=LJS!Jet_FF_2, 1259,355,71,65
gauge145=LJS!Jet_FF_3, 1448,356,67,68

with this

gauge24=JS!JS_ITT_1-A, 1260,267,74,72
gauge25=JS!JS_ITT_2-A, 1351,267,74,72
gauge26=JS!JS_ITT_3-A, 1441,267,74,72

gauge73=JS!JS Eng4_FF, 1540,355,70,70

and this

gauge144=JS!JS Eng2_FF, 1259,355,71,65
gauge145=JS!JS Eng3_FF, 1448,356,67,68

Result should be attached engine gauge view

to XML designers

ITT Gauge
Although I state in nonlinearilty what needles should show(coordinates) , they show too much.I got first time this, what is wrong ?


Thanks

Roland

I don't have gauges numbered this high. I go up to gauge 133.
gauge144=JS!JS Eng2_FF, 1259,355,71,65 >>>> dont have gauge with this number
gauge145=JS!JS Eng3_FF, 1448,356,67,68 >>>>> Ditto

Look for this

LJS!Jet_FF_1(1,2,3,4 ) and relace with this JS!JS Eng2_FF (1,2,3,4 )


That should work

Still the same, no change.
I assumed you meant to change entries in the panel.cfg like so:

Gauge12=JS!JS Eng2_FF1, 837,724, 68, 68
Gauge13=JS!JS Eng2_FF2, 909,724, 68, 68
Gauge14=JS!JS Eng2_FF3, 981,724, 68, 68
Gauge15=JS!JS Eng2_FF4, 1053,724, 68, 68
 
Overspeed

Wish the over speed warning would be fixed. The engine data should be configured to not allow an over speed IMHO.

Just a small nitpick, I know it would take some model rework but I would of liked to see the turbine blades turning.

Lots of planes can exceed Vne / Mme in certain situations; pilot error, not airplane design.

As I did some research and unbeknownst to me:

Vmo Maximum operating limit speed. Exceeding Vmo may trigger an overspeed alarm

Va Design Maneuvering_speed. Speed above which it is unwise to make full application of any single flight control (or "pull to the stops") as it may generate a force greater than the aircraft's structural limitations.

So it looks like all the aircraft have established Vmo and a Vne but the engine(s) don't know it. :encouragement:
 
The JetStar was certainly fast in its day compared with other contemporary corporate aircraft options, e.g., Convair CV-440, DC-3, Lodestar (Lockheed!) etc. However, it was no Cessna Citation X (mach 0.95 cruise). I have read its max cruise at FL30 is about Mach 0.82 - i.e., before over speeding - but would typically cruise efficiently about Mach 0.75.

Mike is right

Please consider that the original plane had four (14.7 kN) thrust Pratt & Whitney JT12A-8 turbojet engines. I read a lot about the plane and even the USAF ones were very fast(and thursty). Pls also consider that you need the trust mainly to climb fast

Now the modelled one has four (16.5 kN) thrust Garrett TFE731-3 turbofan engines- so for sure she theoretically can fly Mach 0.9

BUT after climb you usually reduce throttle as you need to be in healthy ITT , so I guess FDE is quite correct ( and its a Steven Small, which was very accurate in the things he did ) as also ammended by Mike 17- pilot- US Navy and more

Best regards

Roland

Exactly - FAA certification limits were / are 350 KIAS to Mach 0.82 (in other words, whichever is higher; if you start to climb at sea level at 350 KIAS and hold 350 KIAS in a climb, you see your Mach gradually INCREASE due to colder temperature --.Eventually, you might not be able to get 350 KIAS due to engine thrust loss. However, you could still exceed 0.82 Mach at some point). These limits are often based on longitudinal stabiliity limits, where the pilot may start to overcontrol in pitch and overstress or lose control. More modern exec jets and airliners have higher limits because we know more about transonic flight and artificial stability methods.

Yes, best I can see from charts is normal cruise is 0.76 IMN, but you could go as fast as 0.82 at altitude (if high enough and light enough without exceeding engine limits), but what a fuel flow! However when you are cruising at 0.76 - 0.82 IMN at altitude you would have a relatively low IAS. You would have to be careful starting a descent because you could quickly hit the 0.82 IMN limit without reducing throttles. Gradually, your KIAS will build up if holding a constant IMN in the descent - just the opposite of what happened in the climb, and you might hit the KIAS limit if not staying on top of it. This true in any non-combat jet airplane that I can think of, and many turboprops as well.

Combat jets I have flown were usually limited by external stores limits (they could flutter, etc), but the basic airframe could be pointed at the ground at full power with no problems (LBA - "limited by airframe")!
