During a wiki-walk, I found about the Cricketsonde [1] (acronym for Cold Rocket Instrument Carrying Kit sonde) a small meteorological sounding rocket powered by a pressurized mix of carbon dioxide and acetone. The latter is used to increase the reaction mass and thrust duration (carbon dioxide dissolves into acetone) but is not used otherwise.
So I thought about combusting the acetone with ambient air to increase the jet temperature and thus the specific impulse. The pyrotechnic igniter could be based on the PZU used for decades to start the Soyuz family of satellite launchers [2].

Tiens, au fait, tu connais ce gars - qui a trempé dans des affaires bizarres - mais a été l'un des grands pionniers américains du développement des fusées ?

Oui, j'en ai entendu parlé même si je ne suis plus sûr de la source. C'était probablement cet article :
