Submarine Weapon Loading Device with Dual Linear Drives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for loading weapons, such as torpedoes, into submarine torpedo tubes require a significant amount of manual effort and skill, making the process time-consuming and labor-intensive due to the need for precise alignment and retention within the tube.
Innovation Solution
A storage and loading device equipped with two linear drives, where one drive acts directly on the weapon and is moved by another, allowing for extended reach into the torpedo tube, facilitated by a telescopic cylinder or spindle drive actuated by an electric motor, reducing physical effort and time required for loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading methods are used, then precision and control are maintained, but time consumption and labor requirements increase significantly
Solution Approach 1:
The loading device is divided into separate functional modules: a weapon cradle for holding the torpedo, a transport device with linear drives for movement, and a retaining latch mechanism for securing. This segmentation allows each component to perform its specific function efficiently while reducing overall complexity compared to a fully integrated manual system.
Solution Approach 2:
The patent replaces manual mechanical operations with automated linear drives (electric motors or hydraulic/pneumatic actuators). The first linear drive moves the weapon cradle along the torpedo tube, while the second linear drive positions the retaining latch, eliminating the need for manual dexterity and reducing loading time significantly.
2Manufacturing precision
If the weapon is pushed far into the torpedo tube, then proper installation is achieved, but the difficulty of manual operation increases
Solution Approach 1:
The first linear drive automatically pushes the weapon cradle with the torpedo deep into the torpedo tube, achieving precise installation without manual effort. The drive continues until the weapon reaches the proper position, eliminating the difficulty of manually pushing the weapon far into the tube.
Solution Approach 2:
The retaining latch mechanism is automatically positioned and engaged by the second linear drive at the correct position along the torpedo tube. The system self-regulates the retention process, ensuring proper installation without requiring manual intervention to position the latch.
3Productivity
If multiple manual steps are used, then control over the loading process is maintained, but the number of operating personnel required increases
Solution Approach 1:
The patent combines multiple functions into integrated components: the weapon cradle holds and transports the torpedo, the linear drives provide automated movement and positioning, and the retaining latch secures the weapon. This merging of functions reduces the number of separate manual operations and personnel needed while maintaining loading control.
Solution Approach 2:
Manual operations are replaced with automated linear drive systems that can be controlled by a single operator or even automatically. The first linear drive handles weapon transport, while the second linear drive manages retention latch positioning, reducing the number of personnel required compared to multiple manual steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and easy transportation of weapons from storage to torpedo tubes with minimal manual effort, significantly reducing the time and personnel needed for loading, as the device can extend the weapon's reach into the tube and secure it with a retaining latch.
Implementation Method 1
movement of the first linear drive is generated by means of a second linear drive, which is motion-coupled to the first linear drive
Implementation Method 2
a fluid-operated telescopic cylinder is particularly advantageous for this linear drive, as such a telescopic cylinder allows extensions beyond the weapon cradle
Implementation Method 3
The single- or multi-stage extendable telescopic cylinder can be designed as a pneumatic or hydraulic cylinder, with the latter being preferred
Implementation Method 4
a threaded spindle can be rotatably mounted in the weapon recess, preferably in an area below the stored weapon, with the first linear drive being motion-coupled to a spindle nut mounted on the threaded spindle
Implementation Method 5
the weapon is pushed into the torpedo tube until it reaches a locking position, in which the weapon is held by a retaining latch

AI summary
The loading unit for a torpedo (8), in a submarine, has a trough (6) to support the torpedo and a rammer at the trough to move the torpedo into the torpedo tube. The rammer has two linear drives (12) to give added movement paths.
