The device operates as an in-bore ramjet in which a subcaliber projectile, shaped like the centerbody of a cylindrical supersonic ramjet, is propelled through a stationary tube filled with a pressurized gaseous propellant mixture of fuel, oxidizer, and d

From this time on, this accelerator concept has generated considerable interest in various countries, particularly in the USA, Israel, Japan, Korea and France.

A two-dimensional numerical simulation is described and the CFD results are validated against test data from

The Ram Accelerator [., .], (referred to as RamAc), a ramjet-in-tube concept, is a propulsion concept based on using the Shock-Induced Combustion
