"Improved Nose-Rod for Air Bombs" from Tactical and Technical Trends

The following report on German bomb nose-rods was originally published in Tactical and Technical Trends, No. 41, December 30, 1943.

Many earlier specimens of German bomb nose-rods (see Tactical and Technical Trends No. 23, p. 24) have been buckled when recovered, presumably because the angle of impact of the bomb was too oblique. It is assumed that the nose rods now described are intended, by virtue of the solidity of their construction and the
[Dinort Nose-Rod]  
means taken to increase the mutual rigidity of bomb and nose rod, to ensure satisfactory operation for low-level attacks.

The Dinort nose-rod consists of a cast steel cup and plate, welded one at each end of a drawn steel tube as shown in the sketch. Within the cup is welded a central threaded boss which screws into the nose suspension lug recess of an SD 250 (thick-walled, HE bomb, 550 lb) in which position the flange of the cup will embrace the nose of the bomb providing considerable lateral rigidity. The details of the rod follow:

Diameter of plate      9.45 in
Thickness of plate 0.20 in
Diameter of cup 5.55 in
Thickness of cup 0.30 in
Length of rod 14.80 in
Diameter of rod 2.75 in

The whole device is painted buff and the marking Din St 250 is stenciled in white paint on the side of the plate remote from the bomb.
