Investigation on Elastomer Compatibility with Alternative Aviation Fuels

摘要: The introduction of synthetic fuels produced from various alternative approaches has led to the concern over their compatibility with elastomeric seals used in current aircraft engines. aim this research is investigate into issue aviation typical sealing materials. Experimental methodologies employed were stress relaxation test (under both isothermal and temperature cycling conditions) Fourier Transform Infrared (FTIR) spectroscopy. A wide range valuable data was collected detailed analysis carried out using statistical method Hansen Solubility Parameters (HSPs). The outcome establishes fundamental characteristics materials jet via sources. It demonstrates different impacts that individual fuel species may have on seals. correlation been found between molecular structure changes O-rings. HSP suggests a good non-linear equilibrium compression force RED number generated ‘triangle’ data. proved an influential factor terms performance O-ring. Generally, process slows down (accelerates) as decreases (increases). At extremely low temperatures, become very inert would stop. Temperature tests show relationship seals’ ability recovery thermal contraction aromatic content fuel. Based knowledge gained here, recommendations given potential future work related topic.
