The Principal Aspects of Application of Detonation in Propulsion Systems

Typical schema of use of passive elements for acceleration of “plane” flames: helixes (Tshelkin spiral), each helix is characterized by three parameters with the dimensions of length: tube diameter , thickness , and pitch of spiral (a); singly standing rods (“forest” schema) (b) (in addition to the dimensions of an individual rod such as diameter and length , the rod-type accelerator is characterized by the number of the used rods and a law of their distribution in the tube, for example, by the step along the axis, azimuthal displacement in neighboring planes, etc.); disks with holes coaxial (c) (the characteristic dimensions are thickness and displacement of disk, and hole diameter ; the number of holes is of importance also), or with displacement (the dimensions are thickness and displacement of disk, hole diameter and distance among holes) (d).
