Publication number: 20060260499Abstract: A safety and arming device (10) for a spinning projectile fuze, which has a fuze housing (12), which is in the form of a pot, and a bearing body (14) with a booster charge (16). A spherical rotor (42) with a detonator (44) is mounted between the fuze housing (12) and the bearing body (14). A radial groove (22) is formed in the fuze housing (12), and an annular groove (46) is formed in the rotor (42). A holding ring (28) is forced against the annular groove (46), which is axially offset with respect to the radial groove (22), when the safety and arming device (10) is in the safe position. The holding ring (28) is designed with a separating slot (30) and a further, shorter slot (32). The separating slot (30) and the further slot (32) extend at the same distance apart in the circumferential direction of the holding ring (28) and define annular segment jaws (40). The spring device (48) has a pair of cup springs (58), which jointly form a horizontal V-shaped spring profile.Type: ApplicationFiled: December 29, 2005Publication date: November 23, 2006Applicant: Junghans Feinwerktechnik GmbH & Co.

Patent number: 7055436Abstract: A shell fuse has a target acquisition sensor, such as an impact sensor, and a firing train in which a firing device carrier is movable from a safe position into an armed position. Overflight safety all the way to the target is afforded in a simple manner. There is provided a force element, in particular a pyrotechnic trigger device, which can be initiated by the response of the sensor. The force element is coupled to the firing device carrier such that the firing device carrier is movable into the armed position.Type: GrantFiled: December 4, 2003Date of Patent: June 6, 2006Assignee: Junghans Feinwerktechnik GmbH & Co.

Patent number: 6920826Abstract: An energy supply device for a mortar fuse includes a housing, a driven rotary shaft including a cylindrical shaft surface rotatably disposed in a stationary cylindrical bearing surface in the housing, and a fan connected to the shaft for rotating the shaft in a single direction of rotation in a speed range of 30,000-50,000 rpm. Either of the cylindrical bearing surface or the cylindrical shaft surface has a destructible coating of polytetrafluoroethylene, the coating having a thickness in the range of 0.02-0.03 mm, and being destructible in response to rotation of the shaft in the speed range for a period of time no longer than 5 minutes.Type: GrantFiled: November 21, 2003Date of Patent: July 26, 2005Assignee: Junghans Feinwerktechnik GmbH & Co.

Patent number: 6673486Abstract: As activatable battery for an electronic artillery fuse includes an ampoule filled with an electrolyte, and an activation device for rupturing the ampoule in response to the application of an impulse of predetermined minimum magnitude. The activation device includes a timing mechanism for increasing the duration for which the impulse must be applied in order to enable the rupturing to occur, thereby increasing the safety of the fuse.Type: GrantFiled: August 6, 2001Date of Patent: January 6, 2004Assignee: Junghans Feinwerktechnik GmbH & Co.

Patent number: 6463855Abstract: A fuse device for a mortar shell includes an impact weight carrying a detonation charge and arranged to impact against a firing pin when the mortar shell strikes a target. A safety arm locks the impact weight against movement toward the firing pin in a safety position. The safety arm is movable out of locking relationship with the impact arm to establish an armed condition of the fuse device. Energy for moving the safety arm is stored in a spring. That energy is stored after the mortar shell has been launched, because an impeller is rotated by an air flow generated by the moving mortar shell, and that impeller rotation is transmitted to the spring to store energy.Type: GrantFiled: January 5, 2001Date of Patent: October 15, 2002Assignee: Junghans Feinwerktechnik GmbH & Co.
