Yeah, the Aerobee sounding rocket used 20 furfuryl alcohol 80% aniline with
RFNA in a 4400 LbF TCA with a 50KLbF solid booster.

Same in Vanguard talking 19 fifties.

In Ignition! John D. Clark mentions that furfural comes from oat hulls and
Quaker Oats was glad to sell it. It was burned with WFNA or RFNA, I didn’t
see any reference about using it with peroxide.
The book seems essential to those involved with liquid rockets.

I vaguely recall of some (patent?) claims of hypergolic fuels for HTP

discoveries.

Troy -
This is scratching the deepest recesses of my brain but I remember reading
about a HTP-based vehicle in development circa the mid 2000s that was
supposed to use (perhaps wood alcohol?) alcohol as part of the igniter.
The key factor was that it was basically a waste product from… grain
production? Quaker Oats, seriously, rings a bell.
I have no idea what keywords to use to find that article again but it may
well have been something in the nitric acid family and not HTP.

Matthew, you might be getting confused with Nitric Acid (RFNA or WFNA). I
can’t recall any straight alcohol being hypergolic with HTP. I would
definitely be quite excited to learn if there was something not too exotic
available.
