Ramjet Propulsion Performance Analysis

Overview of Project

In this project, an analysis tool for parametric studies of ramjet propulsion performance has been developed, and it has then been used to examine how ramjet performance varies across a range of key parameters such as Thrust, Thrust-Specific Fuel Consumption (TSFC), Overall Efficiency (η_o), and Specific Impulse (I_sp). The analysis tool has been made in MATLAB, due to its excellent flexibility of coding as per requirement

Takeaway from Project

This work presents a detailed study of the performance parameters with respect to variation in the value of different Mach numbers, altitude of flight and efficiencies of different sections of the propulsion system. The temperature-entropy (T-S) diagram, displayed the difference between the states when the combustor is choked and when its unchoked and how choking the combustor could be a blessing in disguise for commercial flights where the more important factor is the overall efficiency of the propulsion system. The report also laid down the differences between the performance of the propulsion system when the combustor was unchoked and choked. The brief study of the two validation cases, indicated the known fact that, choking helps improve the overall efficiency of the propulsion system, while it compensates this increase by degrading the thrust of the ramjet system. However, the decrease in the thrust value led to improved performance of the thrust-specific fuel consumption value by minimizing it.
