Extended Bio

Pearl Jain works with fire — the controlled, engineered, precisely understood fire that powers rockets beyond the atmosphere. She is an Aerospace Engineering scholar and researcher specializing in advanced rocket propulsion systems, high-energy materials, and combustion science, conducting her research at the Centre of Excellence (CoE) Propulsion Laboratory.Her research centers on Solid Fuel Ducted Rocket (SFDR) technology — a class of propulsion systems that combines the simplicity of solid fuel with the efficiency of air-breathing ramjet combustion. SFDR systems are of intense interest for next-generation aerospace applications because they offer higher specific impulse than conventional solid rockets while maintaining the storage and handling advantages of solid propellants.At the core of her work is the study of boron-based metallized fuels. Boron is an attractive fuel additive because of its high volumetric energy density — it packs more energy per unit volume than almost any other material. But boron also presents significant challenges: it is difficult to ignite, tends to form protective oxide layers that inhibit combustion, and requires careful formulation to achieve complete energy release.Pearl addresses these challenges by investigating how additives like iron and titanium can enhance boron's combustion behavior. She studies ignition dynamics — how and when the fuel begins to burn — and regression rates, which measure how quickly the fuel surface recedes during combustion. By understanding these parameters, she can optimize propellant formulations for maximum efficiency and reliability.Her analytical work relies on advanced spectrometer-based diagnostic tools that capture and analyze the light emitted by high-temperature combustion reactions. Different chemical species emit light at characteristic wavelengths, so by analyzing the emission spectrum of a burning propellant, she can identify which reactions are occurring, track their progress, and identify bottlenecks in the energy release process. This allows her to map complex reaction mechanisms with precision.Her work has direct implications for the future of aerospace propulsion. More efficient solid fuels mean rockets that can carry heavier payloads, fly farther, or achieve higher speeds. They mean propulsion systems that are more reliable and more predictable. They mean the difference between a rocket that performs as designed and one that falls short.As an author for ENTECH Magazine, Pearl writes for the aerospace engineering student diving into propulsion, the researcher exploring high-energy materials, the space enthusiast who wants to understand how rockets really work, and anyone fascinated by the science of controlled combustion.
