PRODUCT RANGE

DH40ABF- A1


DH40ABF (Air Burst Function) is a highly effective and cost-efficient nose fuze for 40mm HV timed airburst application. Innovative technology delivers advanced benefits:

  • Precision programmable airburst, implementing eXtended range Magnetic Induction technology (XMI). The selected airburst time is communicated to the fuze, by means of low frequency magnetic induction, in the first 2 meters after barrel exit.
  • No pre-launch stored energy, setback generator powered.
  • Electronic impact sensing, reliable point detonation (PD) assured against targets at impact angles up to 85⁰ NATO.

DH40ABF is suitable for all ammunition types, HE or HEDP complying with STANAG-4403. Either a normal HE or spit back HEDP booster is incorporated.

DL40ABF and DM40ABF are versions for low and medium velocity.

Air Burst Programmers


The DRACO ABF fuze requires programming of the desired time value. This takes place as the fuze exits the gun barrel using the DoppTech proprietary eXtended Magnetic Induction (XMI) technology.

The XMI High Velocity setter is Picatinny-rail mounted to the weapon and interfaces to the sight and fire control system by means of an interface cable. Weapon types such as Mk19, Mk47 and H&K are easily accommodated.

For low velocity applications a range of setter options exists with both manual and serial command control interfaces.

A reserve battery is a primary battery employing liquid electrolyte and a stack of battery plates. The electrolyte is kept in reserve in a sealed container until gun fire, after which the electrolyte rapidly enters the plates forming an active battery.

These batteries have virtually unlimited shelf life due to the physical separation of the electrolyte and the battery plates.

These batteries typically generate voltages from 9 to 24V and can supply currents up to 20mA. Activation times are very fast, typically less than 30ms.

DoppTech produces several such reserve batteries for a variety of fuze applications, for calibres 30mm to 155mm.
