On-board low voltage device for generating plasma discharges for controlling a supersonic or hypersonic engine

Abstract From the Canadian patent

The present invention specifically concerns the field of provisions for guiding or steering projectiles self-propelled or not, or missiles, and concerns a process and an associated device to deviate a hyper-fast projectile (1) operating in a gas for instance a shell, bullet or missile along a direction Y, comprising a generally cone-shaped nose (4) presenting a more or less pointed extremity (29) characterised in that it consists in generating a first high voltage discharge capable of producing plasma onto a first limited sector (28) of the surface of the projectile and on the side of the Y direction and then of maintaining this plasma and of generating another low voltage discharge capable …
