    Figure shows the effects of turbine inlet temperature, cycle pressure ratio, and bypass ratio on thrust and specific fuel consumption for a high bypass ratio turbofan. Thrust is normalized by core airflow, as opposed to total inlet airflow, to restrict the comparison to a constant gas generator size. In gas turbine combustors, the problem appears to arise from a threefold interaction of combustion, system acoustics, and swirl flow aerodynamics. The principal of acoustic streaming is well known in the areas of rockets and ram jets, but its effect has not been considered to the same extent with swirl combustion systems.

So take your time and don't get discouraged. The first question has been addressed in the literature. 6–10 Some of these parameters include fuel concentration, fuel-to-air ratio, temperature, pressure, flow dynamics and residual gas concentration. 6 The hostile conditions prevailing in combustors mean that the selected sensors should be able to withstand exposure to such an environment.
