Latest Patents

Bogdanoff's latest patents include a "Method and apparatus for initiating stable operation of a ram accelerator." This invention describes a technique for supersonically accelerating a projectile in a thermally choked subsonic combustion mode. The projectile is initially pre-accelerated using either a tank of compressed helium or a chemical propellant charge. As the projectile enters a tube filled with a combustible mixture of gaseous fuel and oxidizer, it is propelled by a ram acceleration process. Various devices are employed to control the velocity of the shock wave generated as the projectile enters the mixture, ensuring a stable combustion zone that accelerates the projectile down the bore of the tube.

Another significant patent is the "Apparatus and method for the acceleration of projectiles." This invention involves initially accelerating a projectile to a supersonic velocity before injecting it into a launch tube filled with gaseous propellant. The design incorporates a ramjet system that ignites the propellant in the combustion chamber, further accelerating the projectile through controlled detonation waves. This innovative approach allows for ultrahigh velocity projectile accelerations, showcasing Bogdanoff's expertise in advanced propulsion technologies.
