Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing flying bodies that simulate real-world flight environments for testing is costly and requires complex configurations to move the gravity center position, especially when loading objects or simulating passenger boarding, which is not efficiently addressed by existing technologies.
Innovation Solution
A flying body equipped with a lift generation apparatus and a gravity center movement apparatus, such as a slide mechanism or robot arm, that allows for arbitrary movement of the total gravity center position, controlled by a movement control section to set and adjust the gravity center within specific limits and velocity ranges, enabling realistic simulation of posture changes during flight testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various flight environments are prepared to test a flying body, then flight testing that simulates real-world conditions is improved, but development cost is significantly increased
Solution Approach 1:
The patent uses a weighted portion that can be positioned at different locations to create a virtual copy of various flight environment conditions, eliminating the need to physically prepare multiple test environments. By moving the weighted portion, the system simulates different gravity center positions that would result from loading heavy objects or having passengers board, thereby copying various flight scenarios without building separate test facilities for each scenario.
2Adaptability or versatility
If heavy objects are loaded onto flying bodies or people board flying bodies, then realistic flight testing is improved, but the complexity of inspecting flight status when gravity center position moves is increased
Solution Approach 1:
The movement control section automatically calculates the gravity center position based on the position of the weighted portion and autonomously controls the gravity center movement apparatus to maintain the gravity center at the desired location. This self-service capability eliminates the need for manual inspection and adjustment, reducing the complexity of flight status monitoring while enabling realistic loading simulations.
Solution Approach 2:
The system continuously monitors the position of the weighted portion and uses this feedback information to automatically adjust the gravity center position. The movement control section processes the position data and generates appropriate control commands to maintain stable flight conditions, creating a closed-loop control system that simplifies flight status inspection.
3Adaptability or versatility
If a gravity center movement apparatus is added to arbitrarily move the total gravity center position, then flight testing flexibility is improved, but device complexity is increased
Solution Approach 1:
The weighted portion serves multiple functions: it acts as both the mass that defines the gravity center position and the movable element that simulates different loading conditions. The gravity center movement apparatus, controlled by the movement control section, provides universal functionality for positioning the gravity center at any required location within the flying body, eliminating the need for separate mechanisms for different test scenarios.
