Munition Front Mounting System With Beveled Plate And Rotational Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing munitions lack a robust and flight-worthy method to mount forward component packages on a flat interface at the front of the munition, particularly when traditional legacy interfaces are not available, and there is a need for independent rotation indexing relative to the munition's axial rotation.
Innovation Solution
A mounting system comprising an attachment device with a beveled surface plate and a housing for the forward package, where the housing is joined to the plate using fasteners that engage with the beveled surface, allowing for rotational adjustment and secure attachment of the package.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional legacy interfaces are used for mounting component packages, then the mounting method is simple and familiar, but they are not available as a mounting option on the flat interface at the front of the munition
Solution Approach 1:
The mounting system is divided into separate components: a flat interface plate mounted on the munition, a component package housing, and multiple fasteners. This segmentation allows the flat interface plate to provide a mounting surface where none existed before, while keeping each component relatively simple in design.
Solution Approach 2:
The flat interface plate acts as an intermediary element between the munition body and the component package. It provides a mounting interface on the front of the munition that didn't previously exist, enabling attachment of various components without modifying the munition body itself.
2Ease of operation
If the housing is rigidly fixed to the plate, then the mounting is secure and stable, but rotational adjustment and independent indexing are not possible
Solution Approach 1:
The fastening system transitions from a static rigid connection to a dynamic adjustable connection. The fasteners initially allow rotational movement of the housing relative to the plate, enabling indexing adjustment, and then can be tightened to create a stable fixed connection when the desired orientation is achieved.
Solution Approach 2:
The housing is preliminarily positioned and secured to the plate using fasteners that allow rotational adjustment. This preliminary securing enables the operator to rotate and index the housing to the correct orientation before final tightening, ensuring proper alignment while maintaining mounting stability.
3Adaptability or versatility
If the fasteners are designed to allow rotational adjustment, then independent indexing is enabled, but the permanent attachment capability is reduced
Solution Approach 1:
The fastening system provides dynamic characteristics during installation by allowing rotational adjustment, and then transitions to a static strong connection when tightened. The fasteners are designed to permit rotation when loose but provide strong permanent attachment when tightened, combining adjustability with structural integrity.

AI summary
A mounting system is provided for mounting a forward package on the front of a munition. The front of the munition has a plate joined thereto with a beveled aft peripheral surface. The forward package includes a housing that has an aft portion defined by side walls that provides an opening at the rear of the housing. The aft portion of the housing is configured to fit around the periphery of the plate. Fasteners are provided that are engageable with the beveled surface, and are configured to temporarily hold the housing adjacent the forward surface of the plate while permitting rotational adjustment of the housing relative to the plate.
