Electromagnetic
Mass Accelerator

EMMA, our Electromagnetic Mass Accelerator, unlocks a new approach to hypersonic development by filling the major gap left by today’s testing tools. Existing methods, such as wind tunnels and CFD, struggle to recreate realistic high-Mach, high-Reynolds-number conditions, offer very short test durations, and limit iteration cadence. This slows development and leaves critical behaviors under-validated. ​

EMMA changes this equation. Using electromagnetic acceleration, it launches test models to hypersonic velocities with high repeatability and minimal setup time. In practice, EMMA functions as a “reverse wind tunnel.” Instead of pushing air across a stationary model, we send the model through realistic atmospheric conditions at actual hypersonic speeds. ​

EMMA enables multiple tests per day, dramatically increasing campaign efficiency and reducing costs. It transforms hypersonic testing into a continuous engineering process, enabling faster discovery, deeper understanding, and the rapid advancement of high-speed flight technologies.
