Drop bomb for aircraft.

Addendum to patent 266643.

Patented in the German Empire on July 23, 1912. Longest duration: March 27, 1927.

The invention relates to an aircraft drop bomb of the type shown in patent 266643 Kind in a training in which the priming charge in a tubular extension of the bomb at a distance from that in the bomb body self-lying explosive charge is kept secured until the bomb is dropped and at a certain distance from the point of impact conveyed the explosion of the bomb.

According to the invention, the detonating charge with a when striking the ground Percussion ignition rod or pipe connected to it as a whole can move against the bomb body and thereby the detonating charge 1 in such a Brings that when the detonating charge explodes, the ignition on the explosive charge the bomb is transferred.

ao If the detonating charge is behind the explosive charge before the bomb is dropped, it takes place the shifting of the ignition charge into the ignitable position as soon as the bomb is dropped; is it initially in front of the explosive charge, so it is only moved into the ignitable position when the rod hits the ground.

The bomb is stored or hung on the vehicle in such a way that the ignition rod locks and the detonating charge is at a certain distance from the explosive charge itself is located.

In the drawing is

Fig. 2 is an axial section of the bomb with the tail pipe broken off and

Figure 4 is a top plan view of the primer in the tail tube.

Fig. 5, like Fig. 1, shows the bomb in a different embodiment.

Fig. 6 is a section of the front end,

7 shows one of the central part of the bomb.

In the embodiment according to FIGS. 1 to 4, the ignition charge α is located on a tube a ¹ in the tail tube a ^{2 of} the bomb housing a ³ . In the quiescent state of the bomb on vehicles, the pipe is α ¹ by means of a guided through holes of the tubes a ^1, a ¹ b plug pin against displacement in the tube ² a secured. This pin b can be on the frame b ¹

of the vehicle must be articulated. The bomb hangs on the frame on a horizontal pin δ ² with hand lever c, which is inserted through the eyelets δ ^{3 of} the bomb and an eyelet of the frame δ ¹ .

If the aviator pulls the pin δ ^{2 back} by means of the hand lever c, the tail tube a ^{2 is} free from the pin b , and the ignition tube ^{a 1} can now go down in the bomb to the

ίο to bring ignition charge α into the bomb (Fig. 2). The firing pin c ¹ on the lever c ² is under the pressure of a spring c ³ and rests in the hanging position of the bomb (Fig. 1, 3) on the tube a ¹ ; in the fall position (Fig. 2), however, where the tube a ¹ has gone down by the bomb, the pin c ¹ latches with its carrier c ² under the pressure of the spring and is ^{α by the stop c 4} in the axial position in the tube ² held. It stands here just in front of or above the ignition cap d at the inner end of the tail tube a ² , the continuation of which in the bomb forms the tube d ¹ , and when the head d ^{2 of} the ignition tube a ¹ hits the ignition cap d hits the ignition pin c ¹ , whereupon the explosion takes place even before the bomb body has even hit the ground. The height or the distance from the ground at which the explosion is to take place is determined by the length of the ignition tube a ¹ , and can therefore be changed as required by changing the tube length, possibly by means of extensions or telescopic devices.

The vertical direction of fall with the head d ² down is secured by the caudal fins iZ ^4; a fall delay for the purpose of gaining enough time for the ignition tube a ¹ to fall into ^{the tube a 2} , d ¹ in the position according to FIG. d ⁵ can be in connection with the fins.

If the ignition tube is designed telescopically (Fig. 5-7) in order to lengthen when the bomb falls, all tube pieces a ⁴ can be held in the closed or pushed together position by the plug pin δ (Fig. 7). Spring pawls α ⁵ ο. The like. Are to be provided in order to hold the individual pieces α ^{4 of} the telescopic tube in the extended position. Here the firing pin c ^{1 is arranged} in the bomb a ^s , and the ignition charge α lies in front of the bomb in the first tube a ^l . If the bomb is dropped, the telescopic tube pulls out under its own weight effect, with that mentioned fall delay device ensuring the necessary delay of the fall. When the pipe head d ² hits the ground, the ignition charge α moves into the bomb and the explosion takes place.

Claims (3)

Patent Claims: 1. Drop bomb for aircraft according to patent 266643 with in an approach of The detonating charge kept away from the explosive charge, characterized in that the detonating charge with a on the ground the percussion ignition rod (tube) is connected, which (depending on the initial position the priming charge with respect to the bomb body) either when it is dropped the bomb, as well as when hitting, or only when hitting the ground as a whole against the bomb body can move and thereby brings the ignition charge in such a position that when the ignition charge explodes the Ignition is transferred to the explosive charge of the bomb. 2. Drop bomb according to claim ι, characterized in that a resilient firing pin is held in the disengaged position by the ignition rod (tube) and in the ignition position engages when the detonating charge goes to the explosive charge when the bomb is dropped. 3. Drop bomb according to claim 1, characterized in that the ignition rod (tube) Is composed telescopically, when dropping the bomb pulls out and remains in the extended position. For this purpose 2 sheets of drawings.
