=== What does "sloshed/suitable for aromatic fuel(s)" mean? === | |||
A substance is "aromatic" if it has a "noticeable and pleasant smell".<ref>{{cite web |title=Aromatic |url=http://www.merriam-webster.com/dictionary/aromatic |website=Merriam-Webster |access-date=5 August 2024}}</ref> When used in context of fuels, it refers to a category of chemical compounds related to benzene that were historically grouped together due to the fact they had a common smell.<ref>{{cite web |title=Aromaticity |url=http://en.wikipedia.org/wiki/Aromaticity |website=Wikipedia |access-date=6 August 2024}}</ref><ref>{{cite web |title=Aromatic Compound |url=http://en.wikipedia.org/wiki/Aromatic_compound |website=Wikipedia |access-date=6 August 2024}}</ref> | |||
These types of compounds were added to aviation fuels during the war because they increased engine performance.<ref>{{cite web |last1=Graff |first1=Cory |title=Mustang Was 'Suitable for Aromatic Fuels' |url=http://www.heraldnet.com/life/mustang-was-suitable-for-aromatic-fuels |website=HeraldNet |access-date=6 August 2024 |date=30 April 2014}}</ref> However, they were also highly corrosive and if certain parts of the fuel system of an aircraft were not specially treated, specifically the rubber used in seals and self-sealing fuel tanks, it could cause damage.<ref>{{cite book |title=Aviation Fuels and Their Effects on Engine Performance |date=1945 |page=37 |url=http://app.aircorpslibrary.com/document/viewer/s15fsjwis79 |access-date=6 August 2024}}</ref><ref>{{cite magazine |date=February 1946 |title=The Story of the Self Sealing Fuel Tank |url=http://www.usni.org/magazines/proceedings/1946/february/story-self-sealing-tank |magazine=United States Naval Institute Proceedings |access-date=6 August 2024}}</ref> | |||
The aircraft that had this treatment therefore had a note added to the technical data block on the side of the fuselage that it was safe to use these type of fuels in them. | |||
