What's the octane of jet fuel?
What's the octane of jet fuel? The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
Why is kerosene used as jet fuel?
Lower Cost In some cases, kerosene may cost less than half the price of gasoline. Along with its lower freezing point, higher flash point and lower viscosity, this is one more reason why kerosene has become the preferred type of fuel in the aviation industry.
What can replace jet fuel?
H2 is perceived as an attractive alternative aviation fuel both in recent and past research as it has a great supply potential, contains three times the energy content per weight of traditional jet kerosene (43.2 MJ/kg vs 120 MJ/kg respectively) and does not produce CO2 from combustion.
Is electricity cheaper than jet fuel?
Roei Ganzarski, chief executive of the electric motor manufacturer MagniX, told the BBC that a small aircraft will use $400 on conventional fuel for a 100-mile flight — but with electricity, “it'll be between $8-$12, which means much lower costs per flight-hour.”
