The new rocket, which will be around 30 percent more efficient than exising designs, works on a completely novel fuel mixture of acetylene and ammonia (atsetam)." See: http://www.space-travel.com/reports/...olutionary_Amm.... only a tiny cost of a rocket launch is fuel.. so will this produce more power per pound of fuel? Said to be more easily stored and handled when compared to liquid H2. But I am only looking at press reports so .........the truth maybe in the wind.............Trig |

Apparently, though, a mixture of the two substances - and an issue exists that it could be dangerously explosive in the mixtures required for efficiency - is just the fuel. The oxidizer would still, apparently, be liquid oxygen, which is cryogenic - even if not as cryogenic as liquid hydrogen. Thus, since we already have kerosene-oxygen rockets, it looks as though this would only be an incremental improvement. If a non- cryogenic oxidizer could also have been used while maintaining efficiency - harking back to the original V2 - that would have been revolutionary. John Savard |

John Savard IIRC (I don't have the table in front of me), NH4/O2 isn't too much better than LOX/kerosene. NH4 is corrosive and highly toxic. |
