Clamshell Thrust Reverser Panel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current turbine engines, such as axial flow and reverse flow turbofan engines, lack efficient thrust reversal mechanisms that can effectively transition between stowed and deployed positions, impacting their performance and efficiency.
Innovation Solution
A clamshell thrust reverser system is integrated into the nacelle, featuring pivotable panels connected to a stationary structure, allowing the system to transition between stowed and deployed positions, and is connected to a gear train that links the fan section rotor with the turbo-compressor rotor, enabling efficient airflow redirection for both forward and reverse thrust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a thrust reverser system is added to the turbine engine, then thrust management capability is improved, but device complexity increases
Solution Approach 1:
The thrust reverser system is divided into multiple independent panels that can be individually deployed and controlled. Each panel is a separate component that can pivot independently, allowing the system to achieve thrust reversal functionality through coordinated action of segmented elements rather than a single complex mechanism.
Solution Approach 2:
The thrust reverser panels are designed to be dynamically deployable between stowed and deployed positions. The panels can pivot and move to different configurations based on operational requirements, transitioning from a static nacelle structure to a dynamic system that adapts its geometry to control airflow direction for thrust management.
2Ease of operation
If panels are made pivotable for thrust reversal, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The pivotable panels are equipped with actuators that provide the mechanical force necessary to overcome the weight and aerodynamic forces acting on the panels during deployment. These actuators function as counterbalancing mechanisms that enable smooth transitions between stowed and deployed positions, making the system easy to operate despite the added complexity of movable components.
