Definitions

  • the present invention generally relates to pyrothecnic-producing devices and, more particularly, to a pyrothecnic bomb, finding particular application in warfare.
  • smoke bomb In warfare there are many cases in which the production of a smoke screen is desirable. Some examples include: creation of a reasonably long duration smoke screen to screen friendly ground forces in critical operations, e.g. landing operations, mine field clearing, rescue operations and the like. Smoke screens can also be used for target marking, enemy blinding, decoy operation and for other purposes. It is also generally desirable that the smoke-producing means be designed within a bomb body so as to be easily adaptable to be carried aboard existing military aircraft. It is to provide such a bomb that one aspect of the present invention is driected.
  • the present invention may be defined as a smoke bomb comprising:
  • the smoke comes out from both ends of the main body section, with the main parachutes connected to the main body section.
  • Figs. 1A-1E Attention is directed to Figs. 1A-1E in which the novel smoke bomb is shown in different flight position.
  • Fig. 2 which is a cross-sectional diagram of the smoke bomb, designated by 10.
  • the bomb includes a tail assembly 12, two main pyrotechnic containers 13 and 14 and a compartment 15 for the main parachutes. Also included is a nose assembly 16.
  • the tail assembly 12 contains a mechanical timer assembly 21, which is capable of providing a preset time delay of 3 - 51 seconds.
  • a braking parachute 22 with a delay and ignition system 24 are also included.
  • the smoke producing matter or smoke charge 25 are in containers 13 and 14.
  • In section 15 are located the main parachutes 30 and the deployment mechanism.
  • An auxiliary parachute may be included.
  • the nose section 16 consists of a low drag ogive which houses the nose separation mechanism.
  • a parachute deceleration mechanism 22 which results in the bomb's soft ground landing. This deceleration mechanism is initiated by the timer 21, once released. This enables the bomb to be released from a stand off position.
  • Fig. 1A shows the bomb after release.
  • the bomb continues to descend at a speed of about 25 m/sec., lands softly on the ground and emits smoke from both ends of the bomb's main section, definable as the bomb, less the tail and nose sections. See Fig. 1E.
  • the novel smoke bomb is designable to be carried without modifications by most modern, high performance aircraft or helicopters.
  • One embodiment was actually reduced to practice to be carried by aircraft equipped with standard 14 in bomb carriers. It can be released in level flight, in dive or in pull-up. When in pull-up the bomb can be released from a stand off position thus avoiding the need for the airplane to fly over enemy terrain.
  • the braking parachute like the one shown in Fig. 2 and designated by 22 is deployed. If sufficient pull is applied to it, thus indicating that the bomb is dropping to the ground with sufficient speed, a detonator is activated. It activates the smoke producing matter in two separate smoke chambers A and B. Also the braking parachute and the tail section 12 separate, thus deploying a main parachute B. At about the same time the two chambers A and B separate by mechanism 50. Also the nose section 16 is separated, causing main parachute A to be deployed. As a result the two chambers A and B gently drop to the ground by their respective main parachutes A and B. Consequently two separate sources of smoke are produced.
  • a smoke bomb which is capable of being dropped from an aircraft to produce smoke on the ground. It is only activated when actually dropped from an aircraft as indicated by the pulling force on the braking parachute which initiates the smoke production.
  • any other pyrotechnic effect may be produced, e.g. flashing or continuous light.
  • the term pyrotechnic effect should be regarded as including smoke, light or the like.
