Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weather conditions and wind complicate launch operations for smaller autonomous and semi-autonomous aircraft, such as surveillance drones and blimps, from ground-based launch platforms, as existing systems lack effective load management and release mechanisms to ensure safe and stable launch.
Innovation Solution
A system comprising a launch arm with load cells, an aircraft, and a release mechanism that adjusts thrust generators and control surfaces based on load cell data to ensure safe launch by releasing the aircraft when the load falls below a predetermined threshold, allowing for precise control and compensation of environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a launch arm without load management system is used, then the device complexity is low, but the reliability of aircraft launch is insufficient under adverse weather conditions
Solution Approach 1:
The system incorporates load cells that continuously measure the load on the launch arm and provide feedback to the release mechanism. The release mechanism uses this feedback to determine when to release the aircraft, ensuring safe launch conditions are met before release occurs. This feedback loop significantly improves launch reliability under varying weather conditions.
Solution Approach 2:
The patent replaces purely mechanical launch systems with an automated system that uses sensors (load cells) and electronic control (release mechanism). This substitution allows for more precise and reliable launch control by using electronic sensing and decision-making rather than mechanical alone, improving reliability while managing complexity through automation.
2Measurement precision
If manual release mechanism is used, then the device complexity is low, but the precision of load measurement and release timing is insufficient
Solution Approach 1:
Load cells provide continuous, precise measurement of the load on the launch arm and feed this information back to the release mechanism. This feedback enables precise determination of when to release the aircraft based on actual load conditions, significantly improving measurement precision compared to manual methods.
Solution Approach 2:
The release mechanism is designed to automatically monitor load conditions and make its own decision to release or hold the aircraft based on the load cell feedback. This self-service capability eliminates manual intervention and improves precision through consistent, automated decision-making based on real-time load data.
3Stability of the object's composition
If thrust generator and control surfaces are not adjusted based on load data, then the ease of operation is high, but the stability of aircraft launch is compromised in adverse weather
Solution Approach 1:
The flight control system automatically adjusts thrust generators and control surfaces based on real-time load cell feedback without requiring manual pilot intervention. This self-service adjustment stabilizes the aircraft launch by continuously adapting to changing load conditions, improving stability while reducing the operational burden on the pilot.
Solution Approach 2:
The system uses continuous feedback from load cells to automatically adjust thrust and control surfaces. This feedback loop enables the aircraft to self-correct and maintain stability during launch by adapting to adverse weather conditions and load variations, improving launch stability while keeping the operation simple for the pilot.
