Multi-point Synchronization Network Detonation Technology Research And Application

This paper mainly introduces a technology of opening a cabin of an airborne dispenser's warhead. The airborne dispenser is a new type self-contained flyer which is developed and derived from both early cluster bomb units and a cruise missile. The airborne guided dispenser is known as 'unmanned bomber' abroad.The airborne dispenser's warhead mainly consists of a cabin, submunitions, and initiating devices which can be used for opening the cabin with various performance characteristics. When the dispenser enters the terminal phase of the flight, the terminal guidance technology will be used for positioning precisely. When the dispenser arrives over the target, the cabin is opened, the submunitions are dispensed and the target is attacked. As one of the key technologies for the airborne dispenser weapons, the opening-cabin technology for dispensing has directly influence on the precision to dispense the submunitions and their killing effect. Therefore, the cabin-opening technology is highly respected by many countries.The cabin-opening technology for the airborne dispenser's warhead discussed in this paper is mainly of a non-electrical explosive train which adopts the explosive logic network technology with multiple-point synchronic initiation. The redundancy designs have been made. This explosive logic network technology with multiple-point synchronic initiation simplifies the structure of the cabin-opening system of the dispenser's warhead, improves its precise attack capability and survivability, and saves a great deal of the ammunition resources.The explosive logic network system with multiple-point synchronic initiation mainly consists of insensitive electrical initiators, flame detonators, manifolds, confined detonating fuse (CDF), through bulkhead initiators, linear shaped charge etc. To meet the requirements of the cabin-opening system, deep researches and testing verifications on the key technology of the explosive logic network with multiple-point synchronic initiation were made. The relevant data on the input, transmission, output, safety and reliability were obtained. After a comprehensive environment test on a large quantity of the samples, the explosive logic network technology with multiple-point synchronic initiation in which the initiating devices are primary can meet the requirements of the overall system. The technology will further extend the application and function of initiating devices and offer a new thought for their designs.
