Performance test of a small-scale turbojet engine running on a palm oil biodiesel - jet a blend

The performance characteristics of an Armfield CM4 turbojet engine are investigated by running it on conventional kerosene fuel Jet A and on palm oil biodiesel fatty acid methyl ester (PME) 20% volumetric blend with Jet A. Values of thrust, fuel flow, temperature and pressure distribution along the...
