On February 8th, 2019, the Federal Office for Equipment, Information Technology and In-Service Support of the German Armed Forces held a participation competitionModernization of the 120 mm DM 61 mortar cartridge gestartet.
In addition to the ongoing modernization (in the form of reworking the basic charge and propellant charge) of the mortar ammunition(ES & T reported first in 2016)should in this case, since the shooting accidents 2018(ES & T reported in July 2018) gesperrte Annährungszünder PPD 324 modifiziert werden. Am Ende der Modifikation soll der Zünder nur noch in seiner Zweitfunktion als Aufschlagszünder verwendet werden können.
Unter anderem muss der Bewerber für diesen Auftrag gemäß den Ausschreibungskriterien „ in der Lage sein, die Handhabung und mechanische Modifikation (Anbohren) von nicht inerten Zündern für Mörsersprengpatronen sicherzustellen“. Gut informierten Kreisen nach, soll die Modifikation eine Stilllegung des Windrades beinhalten, welches für die Stromerzeugung des Zünders notwendig ist.
How the PPD 324 works as a proximity detonator:
- Verschuss the mortar round.
- Air flow around the cartridge causes the internal wind wheel to rotate.
- The circling wind turbine generates electricity.
- The detonator uses the electricity to transmit and receive radio signals according to the Doppler principle.
- During the final approach of the cartridge, the transmitted radio signals are reflected by the ground.
- The fuze uses the reflected signals to determine the distance to the ground.
- When the set distance to the ground is reached, the fuze detonates the mortar cartridge.
