Thanks Dan,
I am glad to hear that the rules are not as restrictive as I thought, but
just to make sure I understand let me paraphrase my understanding of the
intent of the rules. Please correct me if I still have it wrong.
The FUEL class is differentiated from GAS by allowing oxygenated fuels
and/or the use of oxidizers other than the atmospheric air. Examples of
oxygenated fuels would be nitromethane, nitropropane, methanol, ethanol,
propyleneoxide, etc.
Examples of non-atmospheric oxidizers would be nitrous, O2 (compressed
oxygen), hydrogen peroxide, etc.
The GAS class is for non-oxygenated gas, or other non-oxygenated fuels such
as LPG, CNG, diesel, etc. Any oxidizers other than atmospheric air are
prohibited.
Where would compressed air go ? Would an engine using compressed atmospheric
air be considered blown ?
Where would non-oxygenated but potent fuels like hydrazine go ?
Thanks for your patience with a LSR novice.
Greg
