英语翻译
The present invention relates to a laser screen device used to test the velocity of experimental projectiles having unstable flight problems.The present invention permits velocity measurements of projectiles having unstable flight trajectories without causing damage to the down range velocity measuring system.The present device may be used to measure the velocity of a projectile regardless of whether the projectile is made of either magnetic or non-magnetic material.The present invention eliminates the need of preflight magnetization preparation of the projectile being velocity tested.
An object of the present invention is to provide a laser screen device for checking the velocity of projectiles having unknown flight characteristics.
Another object of the present invention is to provide a laser screen device for checking the velocity of an unstable flight projectile while protecting the velocity measuring system.
Another object of the present invention is to provide a laser screen device for checking the velocity of a projectile without requiring pre-flight magnetization of the projectile.
Another object of the present invention is to provide a laser screen device for checking the velocity of a projectile which offers the minimum amount of interference with camera coverage of the flight.
Another object of the present invention is to provide a laser screen having a relatively large cross-sectional area for checking the velocity of a projectile having unstable flight trajectories.A further object of the present invention is to provide a laser screen which can determine the velocity of projectiles made of non-ferrous as well as ferrous materials.
For a better understanding of the present invention,together with other and further objects thereof,reference is made to the following descriptions taken in connection with the accompanying drawing.
