Mechanical fuze

Mechanical Fuze. Any fuze which depends for its arming and functioning on events primarily of a mechanical nature. Fuzes may consist of a combination of mechanical and electronic features. Proximity fuzes may contain a mechanical delayed arming device mechanical fuzes may be functioned by electrical energy from a piezoelectric element. The classification is dependent upon which features are predominant... 

Some mechanical fuzes are functioned by electrical energy from a piezoelectric element. Some proximity fuzes contain a mechanical delayed arming device... 

French. Generally speaking, French bombs of WWII were fuzed in nose or tail (or in both) with mechanical fuzes (i.e., contg strikers and detonators, and with... 

Ad 91a) G. Rove, Ordn 39, 831-33(1955) [Mechanical time fuzes, superquick (MTSQ) -M500A1 and M502A1 developed by the Army Ordnance Corps are described. Also is briefly described the early mechanical fuze which was invented in I860 by Lt Tremel of Bavaria) [Note Accdg to Ostankiewicz ( Ref Ad 42), the 1st mechanical time fuze was invented in 1840 in Switzerland and Germany] Ad 91b) M. Zippermayr, Explosivst 1955, 25-40 CA 49, 8601(1955) (Initiation by gas compression heat in various confinements is discussed for TNT,... 

Firing Pin. In a mechanical fuze, contact sensing is converted directly into mechanical movement of a firing pin which in turn is driven into or against (he first element of an expl train (primer). For the simplest solution to obtain initiation using this method, the forces on munition impact are used to crush its nose, thereby forcing the pin into the primer. In a base fuze, (he pin may float in a guide thru which it moves... 

Electromechanical Fuze. Its definition is given in Vol 4, p D882-L, under Mechanical Fuze... 

Before WWI, the two countries who seem to have devoted the most time and money to aerial bombs were Germany Spain. They developed bombs specially designed for use from aircraft. The Spaniards were the first to employ a bomb with mechanical fuze incorporating safety devices to protect airmen launching it. This was during the war in Morocco... 

Espoleta instantanea — Instantaneous fuze Espoleta mechanica — Mechanical fuze Espoleta de ferforante de hormigon — Concrete-piercing fuze Espoleta quimica — Chemical fuze (See also Ref 9, p 65 Ref 13, pp 23, 31,36, 55, 65,99 375)... 

Fuzeless target practice cartridges are used in lieu of expensive HE contg mechanically fuzed rounds, to produce a flash and smoke signal upon impact of the projectile with the target.
