Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid systems for aircraft propulsion and lift generation are separate systems that do not effectively alter fluid flow to enhance propulsion and lift simultaneously.
Innovation Solution
A fluid system comprising a first body portion, a second body portion, a fluid pressurizer, and a duct, where the first body portion has a recess and defines injection and suction openings, and the second body portion is disposed within the recess, with a duct attached to the fluid pressurizer, allowing for controlled fluid flow to create jets for enhanced propulsion and lift.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate propulsion and lift-generating systems are used, then each system can be optimized independently, but the overall vehicle complexity increases and space requirements are not efficiently utilized
Solution Approach 1:
The patent combines propulsion and lift-generating systems into a single integrated structure where a conduit is embedded within the wing, allowing both thrust generation and lift enhancement through coordinated fluid flow control from shared inlet and outlet openings
Solution Approach 2:
The integrated conduit system serves multiple functions simultaneously: it acts as both a propulsion system for generating thrust and a lift-generating system for enhancing aerodynamic lift, eliminating the need for separate dedicated systems
2Productivity
If conventional separate propulsion and lift systems are used, then system design is straightforward, but space utilization and aerodynamic efficiency are compromised
Solution Approach 1:
The conduit is nested within the wing structure itself, utilizing the wing's internal volume to house the propulsion-lift system, thereby improving space utilization without increasing external dimensions
3Productivity
If fluid flow through the conduit is not altered, then system operation is simple, but propulsion and lift enhancement are limited
Solution Approach 1:
The system incorporates dynamic flow control mechanisms that allow alteration of fluid flow characteristics through the conduit, enabling variable thrust and lift generation by adjusting flow parameters rather than maintaining fixed operation
