Alright, I added a emitter doodad and darkened the coil texture a bit. Also extended the top a bit to make more room for feeder tube thingy I tried doing paneling on the texture but i don't like it very much. It's a layer so easy to delete.
Unless there are any suggestions I'll add a thrustTransform and export it in Unity. Also, what scale do we want this at? the base is around 3.25 right now. I'll also include the .XCF in case anyone wants to improve on my textures.

It is lloking good. I prefer the 2.5m as a base.

If I wanted certain acceleration (on last stage) for example 1 (or 10) m/s, then what fuel I should pick for best delta-v in vacuum?

You have the better ISP with Liquid Hidrogen

I know that, but still fuel that has 0.5 ISP of Hydrogen and 3x thrust of Hydrogen would get me ~1.5x more delta V, if I took enough fuel so acceleration would be same between Hydrogen and other fuel.

It\s not the increased thrust that will increase delta V, but the increased density. However, the increased mass will also requires more powerful engines which the increase in thrust is not enough to make up for it, therefore you need more engine power to launch, which will decrease delta V

In my experience, Hydrazine is the best fuel for KSPI, excellent Delta-V and very good thrust also.

im having lots of problems with the radial mounted tanks whenever i launch something with it it just shakes and then blows up... Help

I have tsp 1.1

So densest fuel is best for highest delta-V, if I want certain acceleration?  I'm talking about rocket in space, not when its launching.

What fuel is densest one?

Is it possible to have 1000 km/s of delta v and starting acceleration of 1 m/s? Ship like this would have 2 parts - orbiter and lander.

These parameters would be good for grand tour for RSS.

If I wanted to land on any planet and return, then how much delta V I need in RSS?

THe advantage of Radial mounted tanks is that they allow you to store more propellant for less mass or they can be jettisoned. The disadvantage however is that they are less structural strong which becomes a problem when launching at high speed to low orbit. This is by design. To overcome this,  you could use a steeper of vertical take off.

Choices, choices, they make life interesting.

Water is very dense, but it has a terrible Delta V and oxidizes the engine making it impossible for use in gas core reactors, so I wouldn't use water, unless you are landed on a planet or mun with easy access to lot's of water but no access to ISRU

aerodynamic cones would be nice for x49 and x96 tanks , i use them alot as external droptanks for my ssto's but they break the ariflow .

I believe the others might be wrong, it has been my experience with 1.1  that the Physics (Physx?) Kracken is back with vengeance.    I have had several vessels that had minor parts clipping issues start dancing to the point of explosion.    See if you can move the tanks so they look stupid and are not actually touching the vessel using the KSP part mover in the editor. 

Also: it has been my experience struts almost always make the problem worse with 1.1.

Thank you very much i just reduced the amount

Ok, last picture. INGAME!

Bob approves.


Business end.

[dark jam]

by the way how do you use the reactors 

[Merekthul]

First off I want to say this is by far the most impressive KSP mod I have ever seen.  You should be commended for all the hard work.

To better the further development I wanted to point out a small bug.  The foldable graphite radiators do not seem to have a deploy option, but they do still radiate waste heat.

Keep up the good work.

Thanks, notice that KSPI-E interacts with stock heat part moldule which replaces the deploy and retract buttons

That is good to hear.  1.1 has a lot of phantom forces but the clipping Kraken has been the worst for me.

 

Also reactors are pretty easy to use.  For power you put them next ta  thermal generator and attach a couple radiators to the vessel.  For thrust you just attach a thermal nozzle.  There's more advanced thing's but those should get you started.

In my experience there are two fuels that would suit your needs, argon and xenon (expensive)  these both have high weight ratio of fuel to tank weight and terrific deltav. Hydrazine is good too but it makes me nervous when it's on a vessel . Even carbon dioxide works. Now if you're gonna do ISRU you use what's available.   I personally launch on nitrogen and switch to water in space because of the ease of gathering them.  (Fuel weight is 0% at launch because you can mine it from the atmosphere, my ships weigh 2x more by the time they reach orbit but are light for liftoff )

Hmm liquid fuel has highest TWR of all fuels, when running on VASMIR engine. My little spaceship is capable of 1.5 TWR when running at full thrust (not enough DV then to reach Earth orbit in RSS) and over 40 km/s dv when running on highest efficiency - 10% throttle.

I think my ship could reach orbit with careful ascent - slowly reducing thrust on way up. Also too slow ascent to orbit makes it burn in air.

Here is my spaceship - I installed stock ISRU equipment (produces liquid fuel) so it can refuel itself, when landed on other planets.

You need mech jeb mod - I added this piece of tech on my ship.

thanks you so much i was trying to use the molten salt reactor just by itself and it was not doing anything

That's kinda funny, I  must be thinking of an old version but argon use to produce spectacular thrust and xenon even more with liquid fuel being like 10th best for the plasma engine which should be like the vasmir

[FreeThinker]

Notice the current vasmir will be changed to correct 2 inconsistancies with reality  , VASMIR cannot presurize propellant like NTR (no trust bonus) and cannot possibly operate in an atmosphere. This will give Nuclear/Thermal Turbojet/Ramjet their rightfully value back.
