Cutaway model of a SD-10C (L) Splitterbombe. The Sd-10C (L) was a clusterbomb, 28 SD-10C bombs were carried in a AB (AbwurfBehalter) 250.
The body of the bomb is of pipe material and 76 mm in diameter. It has nine angular grooves around the body to improve fragmentation. A base cap is placed in the base of the body, held in place by a rolled shrunk.
A cast steel adapter on top of the bomb body is also rolled shrunk in place. It houses the e.AZ66 electric impact fuze and the lock up / airflow ring for the fuze.
The tail is made of four pressed sheet metal parts, spotwelded together. It is connected to the bomb body by means of four prongs, punched into corresponding recesses in the bomb body.
A gr.ZdLg.C/98 Np. (Large booster C/98 Nitropenta) is placed below the fuze in a fitting recess in the cast explosive filler in the bomb body.
The bomb has an explosive charge of 0,75 kg Fp 60/40 (Amatol 60/40).
Weight of the complete bomb is appr. 8 kg
Over all length: 20,5 “ (521 mm)
Body length : 12,2” (310mm)
Body diameter: 3,0” (76,2mm)
Wall thichness: 0,55” (14mm)
Tail length : 9,4” (239mm)
Tail width : 3,0” (76,2mm)
There were several types of SD-10 bombs, however all types had a 3,4”dia (86,5mm dia) body. The SD-10C only had a 10mm dia. smaller body to allow more bombs in a AB container.
Other types of SD-10 bombs : SD10-A1, SD-10A2, SD-10FRZ (adepted french bomb).
There was a wide veriaty of types in SD-10C bomb type, the difference was mainly in the production method:
SD-10C (Pr) - Pressed steel body (Presstahl)
SD-10C (L) - Pipe with machined grooves (Rohr mit eingedrehten rillen)
SD-10C (STG) - Cast steel (Stahlguss)
SD-10C (TE) - Tempered cast steel (Temperguss)
SD-10C (SGe) - Special steel cast (Sonderguss)
SD-10C (Pge) - Perlitic iron (Perlitguss)
The bomb was meant to be used against unarmoured targets like: parked aircraft, trucks, personel, artillery positions and supply points.
The bomb is fuzed with the e.AZ.66 (empfindliche AnschlagZunder type 66), however this one is placed on a SD-4 HL.
Functioning of the e.AZ.66 Electric impact fuze for the SD10-C:
The fuze is a plastic mould fuze (1), containing a electric spool of 54 windings copper wire (2), forming a 0,75inch dia coil. A magnitized steel cylinder (3) is placed in the centre of the coil. Above this cylinder an aluminium threaded cylinder is placed (4), housing a screw (5) over which the impeller (6) is placed. The screw has longitudal indentations (knurled) in the upper part and a small square piece is protruding from the lower side. Behind this small square piece a sping (7) is held that serves as a contact switch as soon as the screw is moved upward.
The impeller houses a spring loaded inertia bolt (8 ), which is housed in a of centre channel.
As soon as the bomb is released to the airstream the impeller starts to rotate the air allowed away through the holes in the fuze retaining ring. At a certain moment the rotation is sufficient to throw out the inertia bolt -compressing the spring- , enabeling the lower part of the bolt to grip into the longitudal indentations in the upper part of the screw. This will now unwind the screw, moving the impeller and screw upward and relaesing the spring-contact switch (7), closing the electric circuit. The bomb is now fully armed.
On impact the impeller, the screw and the aluminium upper cylinder are hammered inward –either straight, either angular-, hammering the magnitized cylinder down.
Moving the magnitized cylinder down induces an electric current that runs down the terminal pins the into the squib igniter (red), igniting the detonator and the gr.Zdlg.C/98Np. and the main charge.
