Seeing Inside the Ramjet: NRL’s Optical Diagnostics Promise Major Range Leap
TL;DR Summary
US Naval Research Laboratory researchers used optical diagnostic techniques to observe a solid-fuel ramjet’s combustor, measuring flame temperatures, fuel vaporization, and gas-phase species, and combining these data with high-fidelity simulations (DES/LES) to validate models, potentially increasing operational range by 200-300% and accelerating development through better virtual prototyping for future high-speed defense systems.
