The aim of the study, which is a blend of triple biofuel CSP and the blended fuel preparation with jet-A for B5 (5% CSP-95% Jet-A), B10 (10% CSP-90% Jet-A), B20 (20% CSP-80% Jet-A), B40 (40% CSP-60% Jet-A), and B80 (80% CSP-20% Jet-A) on GasTurb Details-6. GasTurb-14 software used to perform simulations at different engine speeds. Within the calculations made, the thrust, thrust-specific fuel consumption (TSFC), emission (CO 2 , CO, NO x ) and thermal efficiency values of the fuel blends used in the JetCat-P160 engine were predicted and compared with pure Jet-A fuel. As a result of the simulations, it has been seen that the CSP and Jet-A blends reduce the thrust value to around of 130 N for B20, B40, and B80 fuels with the addition of more than 10% CSP to the blend. TSFC values increase as the biofuel ratio increases and reaches approximately 2 times when the B80 and Jet-A are compared especially at low engine speeds. In addition, the prepared biofuels have a positive effect on reducing the harmful emission of CO value due to the content of O 2 . At 39 krpm engine speed, the CO value was 0.19% for Jet-A and 0.07% for B80 fuel and as the engine speed increases, it becomes 0.12% for Jet-A and 0.04% for B80 fuel for the maximum speed of 123 krpm. However, biofuels cause reduced combustion efficiency and delayed combustion and so accelerate the formation of NO x  especially above 78 krpm engine speed.

The effect of using triple bio-fuel blend with Jet-A on engine performance and emissions in mini-scale turbojet engine
