Rocket Stabilizer Separation via Fast-Burning Fuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separation of flight stabilizers from rocket bodies during fireworks displays is not reliably achieved, leading to potentially dangerous situations as the stabilizers can fall vertically and rapidly, posing risks to people and property due to their mass and aerodynamic properties.
Innovation Solution
The implementation of a fast-burning pyrotechnical fuse, such as a five-fold cotton-gunpowder strip in a paper lining, is placed between the stabilizing parts and the rocket body, which explodes at the end of the flight to separate the stabilizers with 100% precision, allowing them to fall horizontally and safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizing parts are made heavier to improve flight stability, then flight stability is improved, but the danger of falling vertically and rapidly increases
Solution Approach 1:
The invention divides the rocket system into separable parts: the stabilizing parts are connected to the body through a detachable connection that allows them to be separated after flight. This segmentation enables the stabilizing parts to remain attached during flight for stability, then detach to eliminate the falling hazard.
Solution Approach 2:
The invention implements preliminary action by providing means for automatic separation that activate at the end of flight. The detachable connection is designed to separate stabilizing parts automatically after the rocket has completed its flight, preventing them from falling vertically without requiring additional ballast or complex control systems.
2Reliability
If stabilizing parts are separated using explosive charge as in prior art, then separation is achieved, but rotation and gyroscopic effect cause unpredictable falling behavior
Solution Approach 1:
The invention extracts the harmful rotational motion and gyroscopic effects from the separation process. Instead of using explosive charges that cause rotation, the detachable connection separates stabilizing parts in a controlled manner that allows them to fall freely without rotation, making their trajectory predictable and safe.
Solution Approach 2:
The invention introduces a detachable connection as an intermediary mechanism between the stabilizing parts and the rocket body. This intermediary enables separation without the need for explosive charges, allowing the stabilizing parts to be released cleanly and fall predictably without rotation or gyroscopic effects.
3Object-affected harmful factors
If maximum weights of stabilization sticks are limited to ensure safety, then safety is improved, but the performance and flight stability are reduced
Solution Approach 1:
The invention makes the connection between stabilizing parts and the rocket body dynamic rather than static. The detachable connection allows the system to adapt its configuration: during flight, the stabilizing parts are attached for maximum stability; after flight, they automatically separate to eliminate safety hazards. This dynamic approach eliminates the need for conservative weight limits.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures that stabilizing parts are separated from the rocket body without additional ballast, resulting in a safe and controlled descent, reducing the risk of injury or damage by minimizing the kinetic energy upon impact.
Implementation Method 1
one or more ends of the fast-burning fuse which are placed in the bottom part of the effective charge holder are activated by the rocket motor in such a way that explosions of the fast-burning fuses separate the stabilizing parts of the rocket motor support with the hundred-percent precision
