		abstract={Turbojet engines are part of a gas turbine that are used to produce thrust 
in aircraft. Along with the times, turbojet engines can still be optimized by 
increasing the pressure ratio on the compressor ( 
) and the speed ratio of sound 
to aircraft speed or commonly called the mach number (M) so that 
thermodynamic analysis is needed on turbojet engines to determine whether the 
engine can be optimized or not.
The thermodynamic analysis process carried out is calculating the 
performance of the VIPER MK601 engine on IAR 99 aircraft with variations in 
the increase in compressor pressure ratio ( 
) and mach number (M) during 
cruising to obtain thrust specific (Fs) and specific fuel consumption (SFC) which 
are calculated using excel to obtain the graph as a result of the engine 
thermodynamic analysis and as a comparison to determine the optimal value of 
the engine's performance..
The results of the performance calculation analysis showed that the 
increase in the compression ratio Fs value increased until the value of ( 
)=10 
then decreased after that point while the SFC value decreased. At an increase in 
mach number, the Fs value has decreased while the SFC value has increased.}
