Description
Technical Field
[0001] The utility model relates to a centrifugal test tool and belongs to the technical field of fuze safety systems. Background Art
[0002] Fuze, also known as fuse tube, is an explosive device installed on ammunition such as artillery shells, rockets and missiles. Fuze is a control device that uses target information and environmental information to detonate or ignite the charge of the warhead of ammunition under predetermined conditions. The detonation sequence of the fuze is composed of pyrotechnics such as detonators, detonating tubes and detonating tubes. Under static conditions, the detonation sequence is in an unopened state due to the isolation effect of the safety system. During launch, the rotor of the safety system releases the safety to center the detonation sequence under the action of centrifugal force and inertial force, and the detonation sequence is opened. The fuze safety system can prevent the accidental explosion of ammunition due to other reasons before the release condition is met, and allows the ammunition explosion sequence to work after the safety is released. The centrifugal release test subjects that need to be carried out during the production of the safety system include non-release test, release test and release flexibility measurement test to prevent the failure of the safety system from causing the failure of the fuze and even the ammunition system, and prevent the occurrence of safety accidents.
