Guided Missile Holding Device Pin Rebound Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current holding devices in guided missile systems cause a pitch-down moment due to the rapid acceleration of the parallelogram, leading to the pin being catapulted back and influencing the projectile's trajectory.
Innovation Solution
A safety device is integrated into the receiving device, featuring a snap-action mechanism or spring hook that prevents the parallelogram and pin from being flung back, ensuring the pin remains in position and stabilizes the projectile's trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the parallelogram is rapidly accelerated during projectile launch, then the holding device can quickly release the projectile, but the parallelogram impacts the receiving device and catapults the pin back towards the projectile, causing a pitch-down moment that influences the trajectory
Solution Approach 1:
The catching device is pre-positioned in the receiving device to counteract the harmful rebound effect before it occurs. When the parallelogram is rapidly accelerated during launch, the catching device immediately engages to prevent the pin from being catapulted back, thereby eliminating the pitch-down moment while allowing high-speed projectile release
2Stability of the object's composition
If the pin is held firmly in the recess during transport, then the projectile remains stable, but the rapid acceleration during launch causes the parallelogram to impact and fling the pin back
Solution Approach 1:
The catching device acts as an intermediary between the pin and the harmful rebound forces. It provides a controlled engagement mechanism that maintains projectile stability during transport through the pin-recess connection, while simultaneously preventing the pin from being flung back during launch acceleration, thus ensuring trajectory reliability
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
The safety device effectively prevents the parallelogram and pin from being catapulted back, maintaining the projectile's intended trajectory and enhancing the reliability of the guided missile system.
Implementation Method 1
For this purpose, a torsion spring, for example, can be used, which can be integrated via a pivot point of the snap-action device
Implementation Method 2
The spring hook allows the parallelogram to be fixed in its final position. During the lowering of the parallelogram, the spring hook is pressed towards the end face, and as soon as the spring hook slides over the upper edge of the longitudinal component, it springs back to its initial position
