[1.0.5] Advanced Jet Engine v2.6.1 - Feb 1

[Dr. Death]

so, no updates on why the game stucks at rapier loading? the only thing that i can think of that changes the way that engines work, wich may conflict with AJE, would be just interstellar, maybe dynamic fairings/wings and deadly reentry.

[Hodo]

Good that you reminded me. It's a bug in the inlet MM patch. The same intake appears 3 times, so it gets 3 times the intake area. You can fix it by removing the other 2 duplicate entries.

Can you expand on this, because I am not sure I am tracking what you are saying.

I've got a few suggestions about what you could add AJE support to.

1). SXT stock extension pack: http://forum.kerbalspaceprogram.com/threads/24906-WIP-LLL-Lack-Luster-Labs-LLL-12-2-10MAY2014-SXT-15-1-09MAY2014

Tiny jet engine - Williams FJ44 http://en.wikipedia.org/wiki/Williams_FJ44

Huge jet engine - Progress D-18T http://en.wikipedia.org/wiki/Ivchenko_Progress_D-18T

2). D12 Aerotech: http://forum.kerbalspaceprogram.com/threads/77894-WIP-D12-Aerotech-A-B9-Aerospace-Expansion-%28Beta1%29

Daisho rotor - Ka-50 rotor http://en.wikipedia.org/wiki/Ka-50

Yari - CH-53E rotor http://en.wikipedia.org/wiki/CH-53E_Super_Stallion

B52 Engine - Twin P&W TF33 (B52 version, of course).

Gladius (radial SABRE), Buzz rotor and ShoutyCraft - something believable (the latter might require messing with the code).

Turboprop - might be though, because it uses MeshSwitch to radically alter it's looks. Reconfiguring it into multiple parts might be the best idea.

3). Coffee Industries: http://forum.kerbalspaceprogram.com/threads/60837-0-23-x-Coffee-Industries-Release-Thread?highlight=CoffeeIndustries

Small basic jet - P&W JT8D http://en.wikipedia.org/wiki/JT8D

Small turbojet - P&W J52 http://en.wikipedia.org/wiki/Pratt_%26_Whitney_J52

These are reasonably popular packs that contain both airplane engines and intakes. Also Spaceplane+ intakes config would be nice, but that's easy enough to make. It's engines that are hard.

Believe it or not, figuring out a reasonable real world counter-part is the most challenging job.

Camlost,

Still have a nagging question about intake area calculations. Is there a way to adjust the area or set the area on new intakes? Trying figure out why the larger variable geometry intakes have less area then the supersonic inlets.

Use tweakscale

[Hodo]

Use tweakscale

Isn't that the mod that lets me change the size of things? How does that tell me how to calculate the inlet size of a given intake?

Or am I mistaken.

I am not looking to make a part bigger or smaller, trying to find out if I have an intake from a mod not supported, and I want to try and figure the inlet aspect ratio so I can add it to the cfg file, how would I do that. Eyeball it?

Really? Well, I can do that for you, if you want. There aren't that many jet engines around, when new ones come up (assuming the RL counterpart isn't obvious), I'll try to think off something useful for them.

Tweak it and the area will scale

The VTOL engines from D12 is not obvious at all, for example

camlost: Hodo is asking how to make the module, not make a bigger intake. Hodo is talking about intakes that don't already have your module.

Also: how come intakes have *better* pressure recovery in the transonic regime than subsonic? Isn't that backwards?

[camlost]

No, why? There's no reason transonic TPR has to be lower than subsonic. Many inlets actually is designed to have optimal TPR at transonic speed.

This right here. Thank you Nathan.

If you want to know the size just compare to an existing inlet

Ok thats all I needed to know thanks.

Camlost: I'm really enjoying this mod. Think I found a bug maybe. The Willliams FJ33 doesn't give any thrust and doesn't use any kerosene. The sound and exhaust animation plays though and I get TWR values etc with MechJeb in the SPH.

I'm a beginner with MM patches, but I found you adress the TVPP part it's based on like this: "@PART[DA?Tiny?Jet]:Final", but it's named as: "DA Tiny Jet" in the TVPP folder. Could those questionmarks be a problem?

Edit: Now I noticed MechJeb says my aircraft has 2m/s^2 acceleration in the SPH and 46 something um/s^2 when it's on the runway. 46 MICROMETERS per second square!

This is with AJE 1.4, latest MM and RealFuels btw. Hope this helps, thanks!

Question mark is the only way to do it, part name shouldn't contain any space, or MM will freak out. The reason you don't have any thrust is that I forgot to add an inlet module to the TV tiny jets. You can add it yourself, or add another inlet

Thanks, that was quick!

I'm getting a similar bug with F-119. This time, it's not because they lack inlets, either:

Neither jet produces thrust, despite intakes being very much present. Using FAR+RSS, BTW.

I have not had that issue yet. I think your problem is you don't have enough intake. I see two of the smaller divertless intakes from B9, they are pretty small and you have them feeding two F119s which are pretty air hungry engines. You may want to go to the larger divertless intakes. This should get you over 50% intake air.

Look at my fighter with the same engines...

Note the intakes are much larger and I have two additional in the wing roots.

I added more intakes and it didn't work. Well, maybe I'll just need to add much more.

[Hodo]

You don't need to spam intakes, for the F-119 engine you only need about 7.5 inlet area to cover most of the intake requirements. If not you have something wrong with your install.

[Guest]

Well, this is supposed to be a high-performance fighter... I'll see what works best.

[Hodo]

And you think the one I posted is anything but high-performance? It tops out at Mach 2.15 @ 15km AGL, super cruise at Mach 1.025 @ 7.5km AGL. Can turn on a dime, is stable and easy to recover from spins, has 6 under wing hardpoints and 2 under fuselage, oh and has 2 wing root mounted .50cal MGs. Can use both Lazertek guided weapons and Skillful weapon systems. Yes it is a high performance multi-role fighter. And it only has those 4 intakes.

Well, the revised Dagger tops out at Mach 2.30 (then the engines explode, it could do more if it wasn't for that), can also turn on a dime (if you overdo it, the wings fall off, though ) and boasts 12 missiles and a 30mm cannon (though the latter shears off too easily, so I might swap it out). It's got 7 intakes, but unlike yours, they're smaller (it has no good place to fit a large one). The only problem is that it's finicky on takeoff, due to gear being a bit too far back. Oh, and thanks to those engines, it doesn't mind stalls at all (could probably pull a Cobra, too).

There are reasons why that aircraft is that size range is one. It can fly on internal fuel from the base in Africa to northern France non-stop all while at super cruise speeds.

The wings on mine stay on at up to 10.5Gs as long as you are not at some stupid dynamic pressure of over 60kpa. And this is my heavy fighter.. I have built a much smaller light weight fighter that is slower but more agile with less range.

And I am sure my fighter can go faster but I wont push it to the engine explosion speeds. Some of tricks I have learned is to set your max engine power to less if your craft is overspeeding and burning up your engine. The other thing is to make sure you are high enough this is not an issue. And I have yet to have an issue with the DEFA 30mm comming off of any of my craft. Where are you mounting yours?
