Fuze energy storage power supply problem

What are the requirements for a fuze power supply?

ii) SIZE & WEIGHT:- A Fuze power supply must fit into a very small space and its weight must not exceed a prescribed limit. Space & weight constraint are more stringent in case of mortar, artillery and small projectiles and less severe in case of missiles, rockets and bomb fuzes.

Which power supply is used in post impact delay fuze?

Capacitors based supply has been used successfully in post impact delay fuze developed at ARDE. 4. Piezoelectric power supply: The piezoelectric element is placed in the nose of the fuze ogive to produce electrical energy upon impact of the warhead.

Which battery should be used in a fuze?

Primary Battery. Lithium Primary battery are especially suitable for use in fuzes because of longer shelf life (10 years), excellent service over wide temperature range (-40 C to +65 C), and capacity to deliver high power density.

What are the requirements for electronic time fuze?

A very short activation time is required in Electronic time fuze. Long range guided projectiles need long active life measured in minutes. A long activation time can be used as arming delay for safety. ii) SIZE & WEIGHT:- A Fuze power supply must fit into a very small space and its weight must not exceed a prescribed limit.

Why do fuzes need a turbo generator?

Where Traditionally storage batteries were used as a power source for fuzes. To overcome their shortcomings like short life, chemical leakages, unreliability etc.; a new technology was required. R&D was carried out, which resulted in the development of wind driven turbo generator that could fit inside the fuze body.

Can reserve batteries be used in fuzes?

New development in the application of reserve batteries to fuzes is the use of lithium thionyl chloride reserve battery. Lithium thionyl chloride reserve battery has been developed for use in Universal VT fuzes for artillery shells. Technology for Lead-lead oxide based reserve battery is to be developed.
