Definitions
- the invention relates to methods and devices according to the preambles of Main claims.
- the present invention is technical The problem is to further develop the generic measures in such a way that satellite navigation on board the projectile, namely for determination the brake release point in relation to the currently flown trajectory to the actually announced goal, decisive through additional measures supported and possibly even replaced.
- Brake triggering is therefore preferred in the context of the present invention when a predetermined point is reached on the previously ballistic movement path supported or even replaced by a counting device which the stabilizing twist of the projectile describing the angle of rotation or speed curve over flight time on the ballistic path as a trigger criterion.
- the outgoing speed is one Artillery projectile quantitative when leaving the gun barrel due to the system is known, and the decrease caused by the dynamic pressure on the ballistic path this initial speed over the flight time or over the distance from Launch site at least qualitatively. That is why the current yaw rate and thus also the currently accumulated number of revolutions since leaving the Gun barrel a measure of the current location of the projectile on its calculated ballistic trajectory.
- All that is needed on board the projectile is in addition to the function of the satellite navigation device for continuous position determination along the ballistic trajectory - or even entirely with the replacement of a satellite navigation device - via a rotation rate sensor or a revolution counter to be determined that by the decreased rate of rotation or by the accumulated number of revolutions predetermined brake release point on the current
- the ballistic flown path has been reached in order to achieve more precise target acquisition now release braking in a shortened, steeply descending trajectory.
- the trajectory itself is no longer required (online) To be determined on board the projectile. Rather, as before, (offline) the cheapest braking trigger point is determined from a flight path simulation and now additionally (also offline in advance) the remaining twist (e.g. the sinking from initially 300 Hz to 180 Hz) or the accumulated number of revolutions Leave the gun barrel (e.g. 20,000 revolutions) for this point on the initial ballistic trajectory that still points beyond the target. The projectile then only needs a braking trigger criterion The only numerical value for the remaining rotation rate or for the total revolutions to be specified, e.g. can be easily implemented in the course of the charging process is.
- the remaining twist e.g. the sinking from initially 300 Hz to 180 Hz
- the accumulated number of revolutions Leave the gun barrel e.g. 20,000 revolutions
- the rotation due to the projectile swirl to determine the rotation rate or Accumulated number of revolutions can hardly be done on board the projectile complex and functionally very reliable, for example by means of a gravitational field responsive mechanical pendulum or by means of a Determine earth magnetic field responsive inductive sensor, because such systems exactly one digital signal to be evaluated per revolution of the projectile deliver.
- the signal frequency is the rotation rate or the signal sum is the number of revolutions, their reaching a predetermined value over the flight time like described as a criterion for triggering the braking device.
- the satellite navigation device which is very expensive in terms of equipment and energy on board a spin stabilized projectile, to determine a brake release point for target-related correction of its initially, the ballistic trajectory, which points beyond the target So according to the invention based on or even replaced by on board the projectile Information that can be obtained from movement, in particular from the projectile swirl.
- the braking trigger point is preferably predetermined by the fact that the projectile taking into account the twist when leaving the launch tube predetermined number of revolutions has accumulated, what on board the Projectile simply by responding to a gravity pendulum, an earth magnetic field sensor or possibly also a position gyro per projectile rotation is detectable about its longitudinal or roll axis.
- this rotation information namely the roll rate of the projectile, like the trajectory from Back pressure and thus also of atmospheric environmental influences in particular how air density is affected is by specifying rotation information at the same time a corresponding independence of the brake trigger point from achieved such interferences.
