INDUCTIVE MICRO-FLASH DESORPTION (IμFD) FOR A MOLECULAR-LEVEL UNDERSTANDING OF FUEL LUBRICITY

摘要

Liquid fuels aboard modern high-performance aircraft currently fulfill the role of not only the propellant, but also a heat transfer fluid and a hydraulic fluid. The fuels themselves have now reached their thermal capacity for effective cooling, and any additional heat load results in unfavorable thermal stress to the fuel, restricting further performance gains. A proposed method to improve the operability of these aircraft and increase efficiency is to eliminate the entire lubricant system and require that the fuel serve not only as the propellant and coolant, but also as the lubricant [1,2]. To enable this transition, it is necessary to identify the important characteristics of fuel lubricity in order to design fuel blends that can optimize this function. In this work, we aim to demonstrate a method for quickly identifying potential lubricant candidates within complex mixtures.
