well, I have the feeling the tiles weren't placed correctly at all...
<bob>
sorry ron was acting like a moron
<bob>
he's an idiot
<raptop>
bob: so, how do you feel about the LV-T30 "Reliant" liquid fuel engine?
<bob>
it's useful as a vacuum engine, like a swivel/reliant equivalent of a raptor for a starship
<raptop>
uh
<bob>
ive seen ron watching someone do that
<bob>
again, sorry for how he was acting
<bob>
he's kinda a [NOT FRIENDLY] idot
<Althego>
couldnt you just coat the ship with a heat shield?
<bob>
would that be more expensive than heat tiles?
<Althego>
it looks like the individual placement is quite labor intensive
<bob>
sometimes labor is needed

working harder is sometimes better, as long as you're working smarter

what kind of particles?

Phonons and Skyrmions come to mind on the materials science side

<raptop>
uh, a bunch of other ones also (eg: plasmons, but I forget what they do)
<Althego>
skyrmion
<Althego>
apparently it does exist
<Althego>
is this because of skyrim?
<raptop>
at least in US-english they're pronounced rather differently so probably not
<ronbutcooler>
why am i not allowed to not like women
<Althego>
you think what you like
<Althego>
but this is not a place for that discussion

<TwistenX>
ok it forced me to disconnect
<TwistenX>
would it to be better to use ethanol or liquid oxygen as a fuel when liquid hydrogen is your oxidizer
<TwistenX>
for an effecient fuel and oxidizer mix
<Althego>
since whn is oxygen a fuel?
<Althego>
and hydrogen an oxidizer?
<TwistenX>
or is it the other way
<TwistenX>
hydrogen, fuel? oxygen, oxidizer?
<raptop>
I'm pretty sure you can come up with a sufficiently silly fuel to make hydrogen an oxidizer, but the only way you're going to oxidize oxygen involves halogen shenanigans
<TwistenX>
ok then
<TwistenX>
should i use ethanol or liquid hydrogen as a fuel with my oxidizer being liquid oxygen
<Althego>
chlorine trifluoride burns everything
<raptop>
For a paper rocket, the answer is obviously hydrogen for Isp or kerosene for TWR
<Althego>
there fore you want to be as far from it as possible
<raptop>
(...and still higher Isp than ethanol because those oxygens in the fuel are IIRC a net loss)
<TwistenX>
im currently starting a "space program"
<TwistenX>
and i'm trying to start with building a solid-fuel rocket as a plastic bottle with some thermal protection
<TwistenX>
and with building a small, yet effecient, liquid fuel (preferably combustion) engine.
<Althego>
bilding a vompletely liquid fuel rocket is hard
<TwistenX>
me and my cousin are going to build a, multi-stage, approximately 15 foot tall rocket but we're building smaller rockets for now
<TwistenX>
i know the simple physics and basic construction
<TwistenX>
the most basic parts of it are a fuel tank, oxidizer tank, pumps for each tank, the combustion chamber, the preburner, and the engine bell/nozzle
<Althego>
you can have a pressure fed engine. no pumps
<TwistenX>
how good compared to a combustion cycle engine is it?
<Althego>
not too good. but simple
<TwistenX>
as long as it's efficient enough, it'll work
<TwistenX>
i see
<TwistenX>
so the pressurizer tank pushes out the fuel and oxidizer into the control valves, then into the combustion chamber
<TwistenX>
i also had an idea for a new type of liquid fuel engine
<TwistenX>
but i don't think it would've worked
<TwistenX>
the idea was a Propane-Ignited Combustion Cycle Liquid-Propellant Rocket Engine. Or the "PICCLIPRE."
<Althego>
not pickle rick?
<TwistenX>
no
<TwistenX>
there isnt even
<TwistenX>
nvm
<TwistenX>
it initially was supposed to work as a crewed-flight engine
<TwistenX>
the way you would control the throttle was a gear connected to the Propane/Ignition Tank that you would twist to increase/decrease the throttle
<TwistenX>
if it were to be used as an un-crewed engine, there would be an arm that would twist the gear
<TwistenX>
that was controlled from earth
Kalpa^ has quit [Quit: Lost terminal]
<TwistenX>
but i don't think that propane can ignite liquid fuel & hydrogen, but there might be another liquid/gas that can
<TwistenX>
i'm gonna need to draw diagrams for some engines and possibly a diagram for the PICCLIPRE
<TwistenX>
Also, what does isp stand for and what does it mean? Also what does it do
Kalpa has joined #KSPOfficial
<Althego>
that is actually I and sp in subscript
<Althego>
specific impulse
<Althego>
basically the physical meaning is exhaust velocity divided by earth's average gravitational acceleration
<Althego>
that is why the delta v formula has a g in it, to egt rid of it
<Althego>
so Isp is in seconds
<Althego>
which is incomprehensible and meaningless
<Althego>
while exhaust velocity has an understandable physical meaning
<Althego>
the fatser stuff goes out, the higher the efficiency of the engine
<TwistenX>
so it's essentially how you measure how long the engine can burn, and how powerful the engine can burn
<Althego>
i understand it better without how long
<Althego>
no, to me it is how strongly it burns
TwistenX has quit [Quit: webchat.esper.net]
<Althego>
but it happened because of historical reasons, since on the apollo program germans and americans worked together
<Althego>
and one would use si the other imperial units
<Althego>
but seconds are the same for both
TwistenX has joined #KSPOfficial
<Althego>
and one would use si the other imperial units
<Althego>
but seconds are the same for both
<Althego>
so by converting it to seconds the could talk about easily
<Althego>
and i need to sleep
Althego has quit [Quit: HMI Module Alpha Humana on approach to Space Station Mercury]
<TwistenX>
So, isp is how strong the engine burns for a certain amount of time, and TWR is just if the engine is powerful enough to lift its cargo
<raptop>
Sorta. There's the old definition of how long an engine can produce a certain amount of thrust with a certain amount of propellant, but the exhaust velocity definition seems easier
<raptop>
And yeah, TWR being thrust to weight ratio. ie: thrust/weight
<TwistenX>
there's a pretty simple way to find out the TWR of an engine and it's cargo
<TwistenX>
you need to put your engine, nozzle down, on a scale, and turn on the scale after you put the engine on the scale so it reads the engine as no weight
<TwistenX>
burn the engine for a few seconds and record the lowest, middle, and highest thrust reached
<TwistenX>
then weigh your cargo
<TwistenX>
if the highest thrust is higher than the weight of your rocket, your TWR is high enough for the rocket to launch
