GENERATOR OF HEATED IMPULSE GRANULAR JETS Russian patent published in 2017 - IPC F42B35/00 F42C21/00 

FIELD: testing equipment.

SUBSTANCE: device contains the hollow body with located inside subsequently and coaxially with the specified initial acceleration direction by the mechanism for the initial spring compression adjustment and the object throwing mechanism under the force of the spring released. The object throwing mechanism is provided with the open front part of the cylindrical channel, with the movable basin disposed inside it, bearing the throwing object, loaded by the compressed spring and held in the initial position by the trigger mechanism. The basin stroke limit switch is provided in the outlet part of cylindrical channel. The dose of heated hard granular heating carrier is taken as the throwing object, which has the initial packing of tapping or tap density with the average poriness 0.4. The hollow body is made from the heat resistant non-magnetic material. The basin is made of ferromagnetic material in the form of a cup with the opened front end, the rear drained bottom, the outer guiding locking belt at the rear part of the cup and inductive connection with the external heating inductor. The spring is connected with the mechanism of initial spring compression and the basin by means of the rod with supports at both ends. The trigger mechanism, equipped with the remote-controlled drive, keeps the spring compressed through the rod support. The opportunity to move the basin with acceleration up to the moment of locking belt impact to the anvil and the formation of the granular jet basin by the throwing object.

EFFECT: increase of the device operation reliability due to the providing the possibility of creating the heat impulse with the specified power and duration on the surface of the igniting material.
