Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rockets for artificial rainfall, primarily using solid propellants, pose safety risks due to mixed fuels and oxidants, and face challenges in approaching clouds with strong precipitation or turbulence, making them difficult to manufacture and handle safely.
Innovation Solution
A rocket design featuring a rocket body with a hygroscopic flare discharge outlet, a communication module, and a hygroscopic flare ejection device that separates and ejects cloud seeds at a desired altitude, allowing control over flight altitude, descent speed, and spray concentration using a parachute and oxidant management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If solid propellant rockets are used for artificial rainfall, then the rocket can achieve high thrust and altitude, but safety risks increase due to mixed fuels and oxidants
Solution Approach 1:
The rocket system is divided into separate components: the rocket body for thrust generation and the hygroscopic flare for cloud seed dispersal. The hygroscopic flare is ejected as a separate entity from the rocket body, eliminating the need to store mixed fuels and oxidants together in the same system, thereby reducing safety risks while maintaining thrust capability.
Solution Approach 2:
The hygroscopic flare containing cloud seeds is extracted and ejected separately from the rocket body after the rocket reaches the desired altitude. This separation removes the hazardous combination of mixed propellants from the upper atmosphere deployment mechanism, improving safety while preserving the rocket's ability to reach target altitudes.
2Ease of operation
If aircraft are used to spray cloud seeds, then the cloud seeds can be sprayed directly into clouds, but safety problems occur when approaching clouds with strong precipitation or turbulence
Solution Approach 1:
The rocket serves as an intermediary carrier that delivers the hygroscopic flare to the target cloud altitude without requiring direct human operation in hazardous conditions. The flare is ejected and activated at the target altitude, allowing cloud seed dispersal into turbulent or precipitating clouds while keeping operators safely on the ground.
3Manufacturing precision
If the hygroscopic flare is ejected from the rocket at desired altitude, then spray time and concentration can be controlled, but the device complexity increases
Solution Approach 1:
The hygroscopic flare is pre-loaded into the rocket body before launch, and the ejection mechanism is pre-configured to release it at the desired altitude. This preliminary preparation allows for controlled deployment without requiring complex real-time decision-making systems during flight, balancing precision with manageable complexity.
