Bolted Flange Fuze Mounting for Penetrator Shock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional penetrator systems struggle to accurately detect and differentiate between thin, soft, or hard layers during penetration due to mechanical noise amplification, leading to miscalculations in the location of the projectable device within a sheltered target, particularly when encountering thin or soft materials like ceilings or soft soil.
Innovation Solution
A fuze mounting assembly with a bolted flange design that securely fastens the fuze to the projectable device, using high-tensile strength fasteners and a compression band to reduce mechanical amplification caused by impact and penetration shock, thereby enhancing the accuracy of acceleration and deceleration sensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fuze mounting is used, then the structure is simple, but mechanical noise amplification occurs during impact and penetration shock, reducing detection accuracy
Solution Approach 1:
The fuze mounting structure is segmented into distinct components: a fuze well, a fuze with integral bolt flange, and separate fasteners. This segmentation allows each component to be optimized independently - the fuze well provides structural integration, the flange provides mounting surfaces, and the fasteners provide secure attachment - while collectively reducing mechanical noise amplification compared to conventional integrated mountings.
Solution Approach 2:
The fuze is pre-configured with an integral bolt flange that includes mounting holes positioned before installation. This preliminary preparation allows for precise alignment and secure fastening to the fuze well, ensuring the fuze is firmly attached prior to impact. The compression band is also pre-positioned to apply force against the fuze, further securing it before shock events occur.
2Reliability
If the fuze is securely fastened to reduce mechanical amplification, then detection accuracy improves, but the mounting structure becomes more complex
Solution Approach 1:
The bolt flange is integrally formed with the fuze body, merging the mounting feature directly into the fuze structure. This eliminates the need for separate mounting brackets or adapters, reducing the number of parts while achieving secure attachment. The flange integrates the fastening function into the fuze itself, maintaining reliability without adding external complexity.
Solution Approach 2:
The compression band acts as an intermediary element between the fuze and the fuze well structure. It applies compressive force to secure the fuze in place while distributing loads evenly, enhancing attachment reliability. The band serves as a mediator that simplifies the overall mounting mechanism by providing a single-component solution for secure fastening.
3Productivity
If thin or soft layers are penetrated, then the projectable device can reach sheltered targets, but mechanical noise from impact shock amplifies, reducing layer detection accuracy
Solution Approach 1:
The secured fuze mounting configuration provides preliminary anti-action against mechanical noise amplification before impact occurs. By firmly attaching the fuze to the penetrator through the bolt flange and fasteners, and positioning the compression band to apply pre-compressive force, the system counteracts the tendency for mechanical amplification during shock events. This preliminary securing action reduces the amplification effect when thin or soft layers are penetrated, maintaining detection accuracy while enabling effective penetration to sheltered targets.
