Embarking on my internship at CSIR - National Aerospace Laboratories marked a graceful shift from the digital realm of simulation software to the enchanting world of hands-on experience. From day one, I found myself amidst a community of dedicated scientists, tirelessly striving to reduce the weight and maintenance cost of mechanical nozzles used in aircraft. Aligned with the collective mission, I was assigned to tackle this very challenge. In the blink of a week, my sanctuary became the library, where I devoted countless hours to delve into the depths of research on nozzles and propulsion technologies. 

The literature review on thrust vectoring captured my attention, prompting me to validate its results. This set the stage for a novel solution to my problem statement. Collaborating with my project guide, we brainstormed necessary design changes. Secondary fluidic injection was the key to creating a virtual throat for achieving supersonic flow at the nozzle exit. Opting for the simplest flat plate geometry, despite limited literature on the topic, I navigated through multiple iterations, designing and simulating each one. We shifted to divergent nozzles as pressure pockets emerged around the injection area. Overcoming challenges through various design iterations, the model evolved from flat plate to convergent-divergent to convergent-double divergent nozzles. 

Despite falling short of achieving the targeted Mach number 2 after approximately 120 distinct designs and simulations, this study serves as a crucial stepping stone towards a revolution in jet propulsion technologies. The research unveiled the potential of the proposed ideology to replace heavy mechanical nozzles, promising easier maintenance. Although this study might appear to be a setback, it led to the publication of a research paper presented at an international conference in Dubai. This work, supported by ample experimental data, holds the promise of earning a patent. Reflecting on these five months immersed in the world of research, I have discovered my craving for in-depth knowledge and my inclination towards bringing an impact. Far from being an end, this marks just the beginning of my journey from being a student to a researcher.
