To guide a projectile on the lens and for determining its ballistic trajectory and devices for implementing the process

摘要

The projectile self-guided passes the ballistic trajectory of firing, followed by a straight-line 25, has a trajectory of the terminal phase from which it is directed onto the lens repere. For this purpose, the instant t7 or the angle of slope is modified so as to leave the straight-line 25 is delayed with respect to the instant t5 fallen of the lens, while the projectile 21 travels in the straight-line predetermined 25, has the result of which only the latter passes on the approach trajectory which is tilted. For determining the instant of change of inclination optimal t7 as a function of the approach of the objective repere, the point of impact z11 of the straight-line 25 is computed on board the projectile 21 by taking account of the ballistic trajectory of the bolt 23.
