Under the condition of high falling speed, because a cloud cluster needs a period of time (hundred milliseconds magnitude) for forming, the resistance coefficient of cloud fog is large, the cloud cluster can be suspended in the air quickly, and the initiation device still falls at the inertial speed, so that the initiation device passes through the cloud cluster before the cloud cluster is formed and cannot be coupled with the cloud cluster, and therefore, the secondary initiation type cloud detonation warhead is often only applied to a low falling speed weapon platform. With the development of the modern air defense back-conduction technology, the penetration capability of a low-falling-speed weapon platform is difficult to guarantee, and a secondary detonation type cloud blasting warhead which can adapt to the falling speed of 300m/s needs to be developed so as to meet the application requirements of some weapon ammunitions.
The Russian cloud bomb is thrown in a parachute deceleration mode, the detonating device is fixed on the parachute, and the detonation device is only suitable for a low falling speed environment of about 30m/s and cannot adapt to a weapon platform with a high falling speed.
In the aspect of cloud detonation technology in America, in order to solve the problem of high falling speed, a cloud and mist detonating device is thrown in the reverse direction of falling speed by gunpowder, the towing speed is counteracted, and the coupling of cloud and mist and the detonating device is achieved.
