Title: Ernst Jensen: Innovator in Projectile Safety Devices
Introduction
Ernst Jensen is a notable inventor based in Furth, Germany. He has made significant contributions to the field of projectile safety devices, holding a total of 7 patents. His innovative designs focus on enhancing safety mechanisms in various types of projectiles.
Latest Patents
One of Jensen's latest patents is an after-firing safety device in a projectile with a percussion fuze. This device features a spiral spring set that includes at least three springs wound in series with opposite directions. The spring set, maintained under tension by a cage, begins to uncoil when the cage slides off due to the projectile's acceleration during firing. The time it takes for a central aperture to be vacated entirely depends on several factors, including the number of springs, their length, tension, and friction characteristics. This safety device is suitable for both spinning and non-spinning projectiles.
Another significant patent is for a training cartridge. This cartridge consists of a metallic case with a shoulder and a dummy projectile that has a gas exhaust opening at its front end. The propellant charge powder chamber is sealed at the front by a cup-shaped closure element that bursts during firing due to the action of powder gases along predetermined breaking zones. The rear of the powder chamber is sealed by a bottom piece inserted into the cartridge case. This design minimizes the risk of injury from ejected cartridge cases by placing the intentional opening zones inside the cartridge.
