Delta and ksp relationship advice

Delta-V Calculator

Consider the two** equations that deal with Delta G (∆G). One of the changes was to remove equation #2 below from the equations. Mass units are arbitrary; use whatever you like, as long as you're consistent. Similarly, Velocity units are arbitrary; the delta-V computed will be. Kerbal Space Program dV Map in US letter Delta V, Space Map, Spacecraft, . Kerbal Space Program - tips for Sips - Album on Imgur .. If you're looking for a detailed discussion of all the potential relationship pairings on the various Star Trek.

Table gives the attunation for various thickness of tungsten radiation shields.

Making sense of ∆G and ∆G°, when it comes to equilibrium

This tells us that a 2 centimeter thick shield would absorb The main things that have to be shielded are the crew, the electronics, the cryogenic tankage, and the magnetic coils if this particular antimatter engine utilzes coils.

The radiation flux will be pretty bad. Well, actually the report says megawatts so obviously I made a mistake somewhere. Anyway the thrust power basically is the fraction of the antimatter annihilation energy that becomes charged pions. The coil coolant systems should be able to handle that. The superconducting coils do not care about the biological dose since the coils are already dead. But you do not get something for nothing. The 10 centimeters of coil shield prevent the radiation from hitting the coils but it does not make the radiation magically disappear.

The coil shield will need a large heat radiator system capable of rejecting You will need more to shadow shield the living crew and sensitive electronics. Our antimatter gamma rays have an average energy of twice that, MeV not MeV. Let's assume the crew habitat module is 10 meters away from the engine instead of 1 meter. Radiation falls of according to the inverse square law.

That is the dose for a 1 Curie source. Our engine is much more radioactive than that. Extrapolating further, a single MeV gamma ray photon has 3. This means a This is equal to 8. Which is quite larger than 1 Curie. This is very very bad since a mere 80 sieverts is enough to instantly put a person into a coma with certain death following in less than 24 hours. The poor crew will get that dose in about half a second.

A shadow shield is indicated. Looking at table again, we see that 14 centimeters of tungsten has an attunation factor of 1. This will reduce the dose to 0. Conceptual schematic for radiation shielding Antimatter Bottle In the conceptual schematic, the reaction chamber is about 1 meter in diameter. The pressure walls have an equivalent thickness of 2 centimeters of tungsten, absorbing most of the gamma rays and coverting them into heat.

The pressure walls are cooled by hydrogen flowing through channels in the wall. The hot hydrogen is sprayed as a film over the exhaust nozzle to protect it from the ultrahot hydrogen plasma blasting out from the antimatter reaction. As per the calculations above, the superconducting coils are shielded with 10 centimeters of tungsten, with the thermal shields aimed at the antimatter annihilation point. Also as per the calculations above, the personnel will be protected by a shadow shield 14 centimeters thick and 0.

It's all about control surfaces. NEAR also makes rockets easier to launch, as the thing no longer calculates drag on all parts, but only the ones that are directly in the path of air. I was able to boost quite a bit more into orbit with just this change.

Still, I might try FAR, see how different they are. It would appear that the community may be split on opinion in regards to B9 or Spaceplanes Plus. From what little I've seen, you either like one or the other. I liked B9, but it was way too many parts. I'm just high on the world Bloody Fossil Sep 17th at 2: There is so many different fuselage systems and stuff, it's had to keep track of. All my delta v numbers for reaching Kerbin orbit are wrong now.

I can down-rate my launch vehicles, as they're massively OP now. Happiness is zero-gee with a sinus cold.

How do I do a Mun flyby in career mode? :: Kerbal Space Program General Discussions

Was still able to boost a rather large parallel-staged mess into orbit just fine Those with Kerbal Engineer or Mechjeb can go ahead and plug it all in and see if I did it right, those who can do this on paper can chime in and see if I did it right, too.

Those who want to simply try it, feel free I'll do up a. If you spot an error, feel free to point it out. We'll start with the 1-man lander can.

On top of that, we'll stick on a standard-sized docking port. We will need that to bolt the lander to our Mun Orbiter. We'll place four RCS quad thrusters onto the top of the pod, along the outer edge so they look nice. That adds another 0. No need for spare monopropellant, the can's internal supply will be sufficient for docking later.

On the sides of the can, we will place two of the small radial Batt-Man packs. We'll use an FLT fuel tank. Grafted to the sides of the tank, are three of the tiny lander legs. To power this midget lander, we'll stick on a S engine.
