Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warheads face challenges in selectively targeting specific areas while minimizing collateral damage, especially in urban environments where civilian facilities are nearby, due to the inability to adjust their explosive performance effectively.
Innovation Solution
An active body with a scalable explosive effect is designed, featuring an active explosive mass, a surrounding shell, a first ignition chain for detonative conversion, a second ignition chain for deflagrative conversion, and a cutting charge that severs the shell to introduce a pressure wave, allowing for precise control between detonative and deflagrative implementations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a warhead uses a single high-power ignition chain for maximum destructive effect, then the explosive effect is maximized, but the ability to minimize collateral damage in urban environments is lost
Solution Approach 1:
The single explosive charge is divided into multiple segments or zones with different ignition chains (first ignition chain for high-power detonation, second ignition chain for lower-power deflagration). This segmentation allows selective activation of different portions of the explosive material, enabling the warhead to adjust its destructive effect from maximum to reduced levels depending on the target and surrounding environment.
Solution Approach 2:
The warhead employs dynamic control of the ignition system, where the choice between detonative and deflagrative ignition modes can be changed based on real-time conditions. The ignition chains are designed to be selectively activated, allowing the explosive effect to be dynamically adjusted between high-power and reduced-power modes, providing versatility in urban combat scenarios.
2Power
If a warhead is designed for detonative conversion only, then the explosive effect is maximized at 100%, but the ability to perform deflagrative conversion for reduced effect is lost
Solution Approach 1:
The explosive charge is designed with multi-functionality, capable of performing both detonative and deflagrative conversion modes within the same charge. The first ignition chain enables detonative conversion for maximum effect, while the second ignition chain enables deflagrative conversion for reduced effect. This universal design allows a single warhead to fulfill multiple mission requirements without needing separate weapon systems.
Solution Approach 2:
The warhead utilizes parameter changes in the ignition process to control the conversion mode. By changing parameters such as ignition timing, ignition location, and ignition energy level between the two ignition chains, the explosive material can be converted between detonative and deflagrative modes. This parameter control provides ease of operation, allowing operators to select the appropriate conversion mode based on mission requirements.
3Power
If the entire explosive mass is converted detonatively, then the explosive effect is maximized, but collateral damage to nearby civilian facilities increases
Solution Approach 1:
The warhead employs partial action by activating only a portion of the explosive mass through the second ignition chain for deflagrative conversion, rather than converting the entire explosive mass detonatively. This partial conversion to deflagration reduces the explosive effect and associated harmful factors such as shock wave intensity and fragmentation, thereby minimizing collateral damage to nearby civilian facilities while still achieving the primary mission objective.
4Reliability
If a barrier layer is used to attenuate the pressure wave, then the sensitivity of the explosive can be controlled, but the complexity of the ignition system increases
Solution Approach 1:
The patent uses an intermediary approach by introducing a barrier layer between the explosive charge and the ignition source. This barrier layer acts as a mediator that controls the transmission of the pressure wave from the ignition chain to the explosive material, thereby controlling the sensitivity and reliability of detonation. The barrier layer can be designed with specific thickness and material properties to achieve the desired level of sensitivity control without requiring complex electronic or mechanical ignition systems.
