Background• Jet fuel - 8 and 16 carbon atoms; depend on the feedstock• Impossible to define exact composition. Traditionally highest quality
available; fostered conservatism by OEMs• Aviation fuel production relies on accumulated experience

Background• Peak oil• Research into production of alternative fuels• Challenge – must be ‘drop-in’ i.e. no alterations to:
– Aircraft components– Ship hardware– Existing infrastructure
• Fischer Tropsch SPK (FT SPK) – 1999• Bio derived Synthetic Paraffinic Kerosene (Bio SPK) – 2012• Synthesized Iso-Paraffins (SIP) – 2014• Alcohol to Jet (ATJ) – 2016

So what?• At very high combustion efficiencies
– ηc = Combustion efficiency – defined by combustion limiting factors
• ηc limiting factor has historically been assumed to be evaporation rate (ηe) only
