thanks for the tip on Newtons third formula
I will check them out next week
RE:SCE to AUX
generating heat for catalyst is a important question
First I need to find out what is the catalyst and how big it is and how much heat it needs
Assuming the heat can be supplied with vituly short circuiting the catalyst across a nicad battery a 70 gram 2400 cell will deliver ~100 amps for some 30 seconds before its runs out of power so 1volt *100amps makes 100watts of heat
more heat regured would mean bigger battery or less heat smaller battery
preferably the solution would be mayby simple lighter procces like a cigerrate lighter with gas that turns on a few seconds ahead of the use to pre heat the catalyst and then as the process is I think heat generating(exothermic ) that will supply the heat for the 3 second to 5 second run hopefully done in away not to ignite the gasses as flame for primitive early versions could add to much complexity
This type of motor proposed can be very seriously heavy compared to rocketry as the weight of the motor is lifted with large wings and thrust ratios are guite low 4kg on AUW take off to fly craft of ~1.2KGs ratio ~3.5:1 which for rocketry is exremly low so it realy reactor stuff
The simplest easiest solution the use of 80% H2O2 isnt possible due to the eneormous seriously enormous problems and costs to get it so its think up something else and N2O nitrous oxide is looking good f the catalyst isnt to expensive and heavy and dosnt need too much starting heat
cant find much info on the net
Again the point of this thread is not to prove what I know and dont know about rocketry as I am not out to make a rocketry project but a low power reactor motor derived from mixxing model RC plane material which I know and elements of rocketry which I can get know if as i conduct trials and experments
First preferences would be buy from off the shelf if it existed at reasonable prices
no sign of that
modify kits but thats not looking to hot an idea so far
Make from plans but the nearest contender solaire gasoline rockket uses the hydrogen peroxide H2O2 so that banjaxed that idea
next idea research any thing similar at all and try to make it or design it and then mayby get say my friends in eastern europe with acces to lathes and things to rattle up a proto type
When the craft is in the air and it lights up and if it goes bang well it will be a serous distance from me falling down onto nowhere ville farming land in stickville
The stactic tests will be done in suitable bunkers to keep noise down to neighbours and 4KG reactor motors cant blow a house to bits not even a brick wall down so the risks are low
N2O2 isnt a realy super dangerous gas if used correctly so I fail to see where I hurt myself seeing as I regularly use 6KG pulse jets and propellers making
10 bhp plus on models which when they shed a prop can be fun to be near
I regret that not being rich and not doing cheque book modeling I tend to try to get the maxxuim power per $$$ I can get
The reason I keep asking what happenes if you mix KNO3 with for example fuels is nobody from any rocketry forums or chemistry forums I pose this question to has any idea
Lots and lots of theories but no imperical facts
and I am not keen to go to a lot of time and trobble to source this stuff and make this mix if all it makes is a shock sensitive fuel which is then absolutly useless to me and cost me money and time
however if the awnswer does not eventualy arrive I will be forced to to conduct limited experments
