rocket engine test ~30N

a test of a homemade rocket engine, 60cm lenght, 5cm in diameter. in this test used 200g of fuel, which at a normal speed burns about 2sec, 100g/s. in the whole engine fits 1.2kg of the fuel, the power of this engine is over 30N.

we'll see how it will go. this is my original fuel, i don't need to compress it as i pour in a melted mixture of kno3,S,C, and sugar. the width of the nozzle is good 5 to 2.3 in diameter, whereas a 5 to 2 test lead to a CATO and enormous average start acceleration of about 100m/s^2. the power was about 20kg. and this was quite a succesful test, the normal force of the engine was over 3kg, and the normal burning speed 5cm/s 100g/s was reached at the 4th sec in the video.

kita karta rasysiu lietuviskai, bo jau anglu sunervino :D. po to visi angliskai kalbantys manys, kad kas pasakyta blogo, tas yra tiesa :D ai jo, ten yra kitam, kaip dega tas kuras, bet be slegio tai ziauriai letai, kazkaip labai keistai i slegi reaguoja :DD, kaip parakas tik inertiskas labai. na laiko turesiu, tai dar tobulinsiu, kad nozzle butu galima det kuo siauresni ir kad kiltu, bei ta aliumini, keisiu plienu, nes laiko tik kokias 10 na gal 15 sekundziu, tai rizikuosiu su 11. :D paziuresim

i think that a slow start could be caused by a wet fuel, so before a flight i'll try to keep the propellant as dry as possible, and for a start i've drilled a short 1cm in diameter hole, which i bet will not be a big mistake :D

the engine remained intact, the nozzle was far more durable, and in the finish there was a blast of fuel remains, which didn't make any special impact. So if it would burn 11secs, it could lift the rocket over 1km(or even a mile) up in the air. So i'll definately keep trying to reach that.

crap, fuel isn`t compressed well, nozzle isn`t strong enough. dude if i say it`s crap, then it is crap :D but respect for creating something, keep working ;D
