METHOD OF SETTING TIME OF CORRECTING ROCKET WARHEAD OPENING OR SEPARATION Russian patent published in 2010 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: proposed method comprises reception of flight mission data from ground hardware, measuring rocket flight parametres by means of accelerometer and computing time correction for warhead opening or separation by preset algorithm. Rocket test magnitudes of acceleration on flight trajectories, time of their actuation and accelerometer individual parametres are entered into onboard hardware permanent memory. In prelaunch preparation, accelerometer initial signal is measured that corresponds to rocket motionless state. Said signal is memorised and subtracted from accelerometer current readings. Then test problem is solved by algorithm intended for calculation of time correction with arguments corresponding to flight mission data received from ground hardware, test accelerations of rocket on flight trajectory and time of their actuation. Results of solving said test problems are sent to ground hardware for it to verify correctness of the solution. If solution corresponds to that made by ground hardware, lockout release signal is generated and received from ground hardware. Accelerometre initial signal magnitudes are allowed for on flight trajectory.

EFFECT: higher accuracy.
