INERTIA SENSOR Russian patent published in 2018 - IPC F42C15/24 

Abstract RU 2642688 C1

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of armaments and, in particular, to the starting devices of rocket shells. Sensor contains a housing with an electric line, an electric outlet and a key made in the form of a two-component microelectromechanical system - the MEMS key. Latter contains two electrically independent contact groups that are open in the initial position. These groups are provided with the possibility of triggering under the action of an overload and are designed in such a way, that the closure of contacts of different groups is ensured by the action of forces whose directions of action for different contact groups are mutually perpendicular. Electronic time block provides the possibility of counting the time of the overload, exceeding the threshold level and forming an electric pulse at the output in case of exceeding the duration of the overload action exceeding the threshold level of a certain time value. MEMS key is located in the housing of the inertial sensor in such a way that the closing of contacts of one group is provided under the effect of longitudinal overload, and the closing of the contacts of the other group is ensured by the action of centrifugal forces when the inertial sensor rotates about the longitudinal axis. One of the contacts of the group is provided with the possibility of operation under the action of longitudinal overload. It is connected to the electric motor of the inertial sensor. Another contact is connected to the input of an electronic time block whose output is connected to one of the contacts of the group. It is provided with the possibility of triggering under the action of centrifugal force. It is connected to the electric motor of the inertial sensor.

EFFECT: improvement of the overall mass characteristics of the launching device, increasing the reliability of its operation during combat use, and increasing security in service circulation.
