English

Subject field(s)
  • Chemical Elements and Compounds
  • Launchers (Astronautics)
CONT

As a result of the larger diameter Vanguard satellite design, the original Aerobee was now too skinny for use as a second stage. A new larger-diameter stage designed by Aerojet-General would have to be used instead. It incorporated an AJ-10 rocket engine that developed 33 kilonewtons(7, 500 pounds) of thrust using the storable propellants inhibited white fuming nitric acid and symmetrical dimethyl hydrazine.

CONT

I have developed several liquid rocket engines using both cryogenic and storable propellants. We have never had a problem with cryogenic propellants(and yes we have never had a LOX valve freeze--you have to use the proper valve). We have shifted over to storable propellants(Inhibited White Fuming Nitric Acid and furfuryl alcohol) because of their high density, hypergolicity, and long term storage capability.

OBS

inhibitor: Substance, naturally occurring or a synthetic additive, whose presence in small amounts in a petroleum product retards or prevents the occurrence of certain phenomena considered undesirable, e.g. gum formation in stored gasolines, corrosion in steam turbines.
