Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid systems in transportation vehicles, such as aircraft, do not effectively integrate propulsion and lift-generating systems, limiting their efficiency and performance.
Innovation Solution
A fluid system comprising a first body portion, a second body portion, a fluid pressurizer, and a duct, where the first and second body portions define an injection and suction opening and a channel, with a fluid pressurizer within the channel to generate both thrust and lift by pressurizing fluid and directing it through ducts as co-flow jets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate propulsion and lift-generating systems are used, then system reliability is maintained, but system efficiency and performance are limited
Solution Approach 1:
The patent combines separate propulsion and lift-generating systems into a unified fluid system where a single conduit integrates both functions. Fluid is drawn through the conduit and ejected to simultaneously produce thrust and generate lift, eliminating the need for separate systems and improving overall efficiency while reducing complexity.
Solution Approach 2:
The conduit system is designed to perform multiple functions simultaneously: it serves as both a propulsion system (generating thrust through fluid ejection) and a lift-generating system (creating aerodynamic lift). This multi-functional design allows a single component to replace what would traditionally require separate systems.
2Productivity
If fluid flow through the conduit is not altered, then system simplicity is maintained, but propulsion and lift performance are limited
Solution Approach 1:
The system incorporates flow delivery driver devices that can dynamically alter fluid flow characteristics within the conduit. These devices enable adjustment of flow rate, direction, and velocity to optimize propulsion and lift performance under varying operating conditions, transforming a static system into an adaptive one.
Solution Approach 2:
The patent employs mechanisms to change fluid flow parameters (such as flow rate, pressure, and velocity) within the conduit to enhance performance. By adjusting these parameters, the system can optimize both propulsion and lift generation according to specific operational requirements without fundamentally changing the system architecture.
