Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turbine engines, such as those used in aircraft, face limitations in generating sufficient pressure and propelling force due to suboptimal compressor and turbine designs, leading to incomplete fuel combustion and reduced propulsion efficiency.
Innovation Solution
A fluid supercharging device with rotating fan blades featuring centrifugal fluid guiding structures, including fluid guiding inlets and outlets along the length of the blades, generates centrifugal force to enhance fluid flow velocity and pressure difference between the windward and leeward sides, increasing engine pressure and propelling force through a multi-stage vane disc and turbine configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a multi-stage compressor and turbine structure is used to increase internal pressure, then the pressure generation capability is improved, but the fuel combustion completeness deteriorates due to insufficient pressure
Solution Approach 1:
The fan blade is segmented into multiple functional regions: windward side for fluid intake, leeward side with fluid guiding inlet for secondary fluid entry, and internal fluid channel for fluid transport. This segmentation allows different parts of the blade to perform specialized functions that collectively enhance pressure generation and fluid mixing for complete combustion.
Solution Approach 2:
The fluid channel is nested within the fan blade structure, with the fluid guiding inlet positioned on the leeward side and the channel extending along the blade length. This nested configuration allows the blade to simultaneously perform its primary propulsion function while housing an integrated fluid transport system that enhances combustion efficiency.
2Force
If fan blades rotate to generate centrifugal force for fluid flow, then the propelling force is improved, but the structural complexity increases due to fluid guiding inlets and internal channels
Solution Approach 1:
The fan blade is designed as a multi-functional component that simultaneously generates centrifugal force for propulsion, guides fluid flow through its internal channel, and facilitates fuel-air mixing. The leeward side fluid guiding inlet and internal channel are integrated into the blade structure, allowing it to perform multiple functions without requiring separate dedicated components, thus managing complexity while enhancing performance.
3Stress or pressure
If fluid flows along different paths between windward and leeward sides at different velocities, then the pressure difference is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different regions of the fan blade are designed with locally optimized characteristics: the windward side is configured for high-velocity fluid intake, the leeward side includes a fluid guiding inlet positioned at a specific location, and the internal fluid channel has specific dimensions and orientation. This local quality differentiation creates the desired velocity differences and pressure gradient while providing clear manufacturing guidelines for each specific region.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly enhances the propelling force by creating a pressure difference that collaboratively increases engine pressure and fuel combustion efficiency, resulting in improved propulsion performance compared to traditional engines.
Implementation Method 1
the fan blades rotate to generate a centrifugal force such that a fluid flows into the fluid channel via the fluid guiding inlet on the leeward side
Implementation Method 2
the fluid flows along different paths between a windward side and the leeward side of the fan blades in different flow velocities to generate a pressure difference
Implementation Method 3
a gas intake of the suction motor is in communication with the fluid channel and operable to extract gas stream under action of a driving force, such that a fluid flows into the fluid channel via the fluid guiding inlet on the leeward side and generates an accelerated flow velocity within the fluid channel
