Mnie raczej limituje nie ciśnienie a wytrzymałość termiczna korpusu w czasie. A tego wyliczyć nie potrafię. Moim celem jest silnik papierosowy o ciągu 100 N przez 20 s. I główny problem to te 20 s...Właśnie taki zrobiłem,się suszy, ciekawe tylko czy da radę...Silnik startowy też mam gotowy, ale on to pikuś.
Pozdrawiam.
