ETD TIME FUZE

NSN: 1390

The ЕTD is a fuze with wireless input of the time of delay.
It is designed to be used on mortar rounds of calibers 60 mm, 81 mm, 82 mm and 120 mm
in smoke and illumination applications.
The preset time of delay can range from 2 up to 99.9 s (in 0.1 s increments).
Its value is saved in a read-only memory, which is capable of multiple reprogramming.
The programmer has a LED display for visualizing the time of delay, and a light-emitting diode
to indicate the successful memorizing.
A contact impact action and a time of self-destruction are provided for self-destruction.
In accordance with STANAG 4187, an inertial mechanism and a linear acceleration sensor
provide arming at a safe distance.
