Title       The design of bomblet fuze capable of self-destruction and self-neutralisation and self-deactivating 

Abstract This essay comes up with a general design scheme for fuze, in which it is composed of spring-slider mechanism, aerodynamic mechanism, centrifugal spring-pin mechanism , circuit and power supply, based on Tactical and Technical Indexes of a certain bomblet fuze launched by Mortar-Howitzers。 And 2D engineering drawings are accomplished, as well as three-dimensional model built by Creo, after the structure size is designed。 The design calculation is figured out, the result indicates that  the designed fuze is able to ensure its safty in service process and reliability in arming process。 The methods for the fuze to achieve self-destruction, self-neutralisation and self-deactivating is put forward and principle circuit is given。 Lastly, strength check focused on springs and weak links on the fuze are carried out, the result indicates that no parts of the fuze will be damaged under the launching-overloading, the fuze can work normally。
