Hi all,
I am a 51 years old italian structural graduated engineer since 1986, but from the age of 15 my major interest out of my job is amateur/experimental rocketry (I built and flight rockets with zinc/sulfur motors made by myself since 1973). You can explore my current activity visiting: www.labsa.it.
Now I am trying to design a liquid rocket engine exploiting a nitric acid/furfuryl alcohol (or turpentine, or other fuel) propellant. However my major concern is about the concentration of HNO3 (no more of 69% commercially available in Italy). Could a 69% nitric acid still be an oxidizer for rocket engine pourposes (even with reduced performance compared to WFNA or RFNA?) Could anyone help me?
Many thanks in advance,
Livio
