Separable Projectile Payload Container for Test and Effect Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separable projectile designs are inadequate for safely recovering sensitive measuring equipment during testing, as they often result in damage, and lack flexibility for modifying between test and effect embodiments.
Innovation Solution
A method and arrangement for modifying a separable projectile by changing the payload container from measuring equipment to effect parts, using a separation charge, such as a propellant or pyrotechnic primer, to safely separate the payload container from the projectile, allowing for easy conversion between test and effect embodiments, and incorporating a parachute for recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projectile is designed as a separable projectile with effect charges, then terminal effect capability is improved, but the projectile cannot be used for testing measuring equipment during acceleration and trajectory phase
Solution Approach 1:
The projectile is divided into separable components: a reusable projectile body and a replaceable payload container. The payload container can be detached and replaced to switch between test embodiment (with measuring equipment) and effect embodiment (with effect charges), enabling dual-use capability without redesigning the entire system.
Solution Approach 2:
The projectile body is designed with universal interfaces and attachment mechanisms that can accommodate different types of payload containers. This allows the same projectile body to serve multiple functions by simply changing the payload container, supporting both testing and operational missions.
2Adaptability or versatility
If the projectile is designed for terminal effect only, then terminal effect capability is improved, but it cannot be modified for testing measuring equipment during acceleration and trajectory phase
Solution Approach 1:
The payload container is designed as a separate, pre-configured module that can be attached to the projectile body without complex assembly. This segmentation allows the container to be manufactured and tested independently, then quickly installed on the projectile body, simplifying the modification process between different embodiments.
Solution Approach 2:
The payload containers are pre-configured and pre-tested in their respective embodiments (test or effect) before being attached to the projectile body. This preliminary preparation reduces on-site modification complexity and ensures readiness for immediate deployment or testing.
3Ease of operation
If the measuring equipment is recovered by slowing the projectile in compacted bales backed by a sand trap, then recovery is achieved, but the sensitive measuring equipment is damaged
Solution Approach 1:
The measuring equipment is extracted from the projectile body by detaching the payload container before recovery. The separated payload container with measuring equipment can be recovered independently using gentler methods (such as parachute deployment), avoiding the high-impact recovery process required for the full projectile and thus preventing damage to sensitive equipment.
Solution Approach 2:
The payload container is designed with protective features and separation mechanisms that cushion the measuring equipment before recovery. The separation occurs prior to the high-impact recovery phase, and the container itself provides protective cushioning during the recovery process, preventing damage to the embedded measuring equipment.
4Strength
If the projectile body and payload container are permanently integrated, then structural integrity is improved, but the projectile cannot be modified between test and effect embodiments
Solution Approach 1:
The projectile is segmented into a reusable projectile body and a replaceable payload container connected by a separable interface. This segmentation maintains structural integrity of each component while enabling flexibility to swap payload containers between test and effect embodiments based on mission requirements.
Solution Approach 2:
The interface between the projectile body and payload container transitions from a static permanent connection to a dynamic separable connection. This allows the system to adapt its configuration dynamically - permanently integrated during a specific mission phase, then separable for reconfiguration to a different embodiment, providing both strength during operation and flexibility for modification.

AI summary
A method for modifying a separable projectile between a test embodiment or an effect embodiment includes detaching the front projectile body from the rear projectile body, arranging a payload container in the front projectile body where the payload container comprises measuring equipment or an effect part, and fitting the front projectile body to the rear projectile body by way of a belt. A separable projectile which can be modified between a test embodiment and an effect embodiment is also provided.
