Jet Stream Balloon Navigation With Apparent Wind Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current weather balloons lack the ability to maneuver horizontally within the jet stream, leading to incomplete data collection and inaccurate weather predictions due to their limited lateral movement control, which is crucial for maintaining position within the jet stream.
Innovation Solution
A lighter-than-air vehicle (LAV) equipped with an altitude movement device and an apparent wind generating device, such as a motorized propeller or drag balloon, to navigate laterally within the jet stream, combined with a three-vehicle control system for precise lateral movement and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If weather balloons are used for jet stream navigation, then data collection is possible, but lateral movement control is insufficient causing the balloon to drift out of the jet stream
Solution Approach 1:
The patent applies dynamics by making the balloon's lateral position adjustable and controllable rather than fixed. The system uses variable buoyancy distribution and aerodynamic control surfaces to dynamically respond to jet stream conditions, allowing the balloon to actively maintain position within the stream despite wind variations and drift forces.
Solution Approach 2:
The patent changes physical parameters of the balloon system to enable lateral control. This includes modifying buoyancy characteristics through adjustable ballast or gas volume, changing aerodynamic properties with control surfaces or appendages, and adjusting mass distribution to create lateral movement capabilities that were previously absent in conventional weather balloons.
2Quantity of substance
If discrete weather balloon observations are used, then some jet stream data is collected, but coverage is incomplete leaving large areas unmeasured
Solution Approach 1:
The patent implements continuous useful action by enabling balloons to remain within the jet stream for extended periods through active lateral position control. Instead of drifting out and requiring replacement, the controlled balloons can continuously track and measure jet stream parameters along their path, providing ongoing data collection that fills coverage gaps and reduces information loss.
3Speed
If weather balloons drift like flotsam in a river, then they follow the wind flow, but they quickly glide out of the jet stream path and fall to the ground
Solution Approach 1:
The patent applies feedback control by continuously monitoring the balloon's position relative to the jet stream center and adjusting lateral control mechanisms in response. Sensors detect drift from the desired path, and the control system responds by modifying buoyancy distribution or aerodynamic forces to correct the position, creating a closed-loop system that maintains prolonged engagement with the jet stream.
