STARTING MECHANISM Russian patent published in 2018 - IPC F42C15/24 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to weapons. Starting mechanism includes a housing with an electric branch and an electrical outlet, inside which there are two microelectromechanical systems keys, opened in the initial position and triggered by overload, an electronic time block providing an overload time counting time exceeding a threshold level, and forming a control signal at the output, in the event that the recorded time exceeds a certain value. One of the MEMS key is located in such a way that the closing of the contacts is carried out under the influence of an overload exceeding the threshold level, acting along the longitudinal axis of the trigger mechanism. Another MEMS key is located in such a way that the closing of the contacts is carried out under the action of a centrifugal force, when the trigger is rotated relative to the longitudinal axis. One of the contacts of the MEMS key activated under the action of longitudinal overload is connected to the electric motor of the trigger mechanism, and the other contact is connected to the input of the electronic time block, the output of which is connected to one of the terminals of the MEMS key triggered by the centrifugal force, the other contact of which is connected to the electric output of the trigger.

EFFECT: invention makes it possible to achieve an improvement in the mass-dimensional characteristics of the trigger mechanism and an increase in the level of reliability of operation during combat use.
