[WIP][Parts]Krakon Works - need help

[MatterBeam]

Hi.

I'm trying to make two electrothermal jet engines.

The first is a resisto-aerojet. It is tungsten heat exchanger that works like the electric version of the nuclear thermal turbojet. It should come out as a use-anywhere-anytime jet engine that can be used equally well on Duna as on Kerbin, at the cost of a lot of electric charge.

EDIT:

Getting there (testing in RSS Earth with FAR and DRE):

I think you would have to change ElectricCharge to something new make a new charge and give it a density.

EDIT- You might try and make a RESOURCE DEFINITION file

RESOURCE_DEFINITION

{

name = TurboEC

density = 0.005 // <---- You might have to play around with the #

unitCost = 0

flowMode = ALL_VESSEL

transfer = PUMP

isTweakable = true

}

How would that help as a propellant instead of just using Ec?

[Mecripp]

Ec don't have any density and so by playing around with it if you change the density and then look at the per sec used.

[FreeThinker]

Giving ElectricCharge a density sounds like a realy bad idea

[Mecripp]

Thats why, I would make a new RESOURCE to do it.

There has to be a better way.

[Mecripp]

How are planning to get this 222Ec per sec at to run the engine ?

Custom self-contained reactors based on a 150% efficient version of the Hyperion Power Generation technology listed here and here. They'd have a power density of about 2MWe/ton.

Here is two ways, You would have to play with the #. https://dl.dropboxusercontent.com/u/72893034/EC_Jet.zip There two jets and 1 intake.

Well, first of all, major thank you. You actually went the length of writing up demo mod files.

If I understand correctly, the first solution 'JetEngine3_EC_RAM' is a combination of air intake and jet engine, where the air intake generates a new resource, and the jet engine consumes this new resource alongside IntakeAir.

The second solution is to add a generator module to the jet engine that consumes electric current to produce a new resource, then the jet engine consumes this new resource alongside the IntakeAir.

I really like the second solution. It allows me to impose a continuous minimum electrical consumption rate for running the jet. I wonder, is it possible to have electric current consumed both by the 'generator' and as propellant at the same time?

[Mecripp]

Would think so.

Would think so.

EDIT- And forgot to take off the ModuleAlternator as you can see it was set way high and it was just for testing.

Yeah, I made the appropriate corrections.

I found out that the 'resource generator' module works fulltime, as in, it draws Ec even when the resource reserve is full, or if the engine is at zero thrust. Also, the thrust displayed in the VAB is not just a random number, it is exactly 50% of the value I wanted it to be.

I'll return after more testing.

PS: I finished making the reactors. I used stock models. Currently, they are textureless white. 45, 20 and 5MW versions.

[Mecripp]

You could add a on and off and not sure if there is if it's full to shut off will have to look around and thats why the intake might be better for that.

I'm currently testing using electric charge directly. Results seems promising. I'll post pictures if I get the correct propellant ratios.

Although, I do not understand how the regular turbojet uses a maximum of 1.16units/s of intakeAir, but the electrothermal jet I'm using, with even better ISP, and the same fuel/air ratio, manages to use a huge 5.36 units/sec of intakeAir.

Okay, here's an Album.

[Mecripp]

So were are this test engines

[MatterBeam]

Oh, I'll put them up.

I'm intending on using the OPT Aerie model for the Pulsed Electrothermal Jet, and one of the Near Future Electrical engines for the Resisto-Aerojet. I'm just making sure with licensing that I can publish their models as my own, with due credit.

[MatterBeam]

Here's something I've done on Sketchup on my first attempt ever at making models.

[MatterBeam]

I should have something in a few minutes.

[Mecripp]

More things to test out

[MatterBeam]

Yeah. Redid everything from scratch using Blender directly. Learnt about something called 'thrustTransform'.... Loading KSP to check if my new knowledge was applied correctly...

- - - Updated - - -

Okay, here's another album. I've got more outdated tutorials to slog through, it seems.

Okay, I have something. Did an attach node, engine glow, gimbal range and thrust test... all came out at a 'good enough' quality. Making more fixes before I start my own mod shop and post this as the first mod.

It reaches Mach 4.8 on this craft before the thrust (lowered due to reduced heat transfer at higher airspeeds) cannot overcome the drag on this craft.

[Mecripp]

You been busy

[trekfan42]

On your front post it says you didn't know what ISP is. Its basically fuel efficiency. The higher the number the less fuel your engine uses up per location. Like you can change rocket engines to have better efficiency in space as opposed to atmo.

Sorry if you already learned this.

BTW. I'm drewdus42 from reddit
