# Practicality of High Energy/Zip Fuels?

High energy/zip fuels were developed in the 1950s as a next generation fuel for aircraft and rockets but were largely abandoned due to the risk of damaging turbine blades. The last projects to consider using the fuels were supersonic aircraft that would have run conventional fuel through the engine and only used the high energy fuels for the afterburners.

Most of the research focused on borated fuels, but I'm wondering if there are any other fuels that could have been used. Also, could could high energy gasoline fuels have been developed for use by combustion engines?
