Pivoting Thrust Reverser Mounting for Open-Position Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thrust reversers on aircraft engines are prone to damage during maintenance and towing due to inadequate support in the open position, which can compromise the integrity of seals and increase the risk of fire propagation.
Innovation Solution
A mounting assembly that supports thrust reversers with pivotally connected arms and base assemblies, allowing them to move between angular positions to maintain stability and prevent damage during engine core removal and towing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thrust reversers are positioned in open position to allow engine core removal, then access to engine core is improved, but thrust reversers and seals can become damaged due to inadequate support
Solution Approach 1:
A support assembly with arms is introduced as an intermediary device between the thrust reverser and the aircraft structure. The support assembly provides temporary mechanical support to the thrust reverser sections when in open position, preventing damage while allowing maintenance access. The arms connect to the thrust reverser sections and maintain them in a supported position during engine core removal.
2Stability of the object's composition
If thrust reversers remain connected to aircraft during towing, then connection stability is improved, but excessive forces are applied to thrust reversers causing damage
Solution Approach 1:
The support assembly acts as a mediator that decouples the thrust reverser from direct stress during towing operations. By providing independent support to the thrust reverser sections, the assembly prevents transmission of excessive towing forces to the thrust reverser structure and seals, while maintaining connection stability.
3Strength
If thrust reversers are in closed position, then structural support is improved, but seals become damaged due to compression against wings
Solution Approach 1:
The support assembly enables dynamic positioning of the thrust reverser sections. Rather than forcing the thrust reverser into a fixed closed position that compresses seals, the assembly allows the sections to be held in intermediate or open positions where structural support is provided without seal compression, making the system adaptable to different operational requirements.

AI summary
A mounting assembly to support a thrust reverser that is mounted to an engine mount of an aircraft. The mounting assembly includes a support assembly configured to connect to the engine mount of the aircraft with the support assembly having a first lateral side and a second lateral side. A first arm is connected to the first lateral side of the support assembly and is configured to connect to a first section of the thrust reverser. A second arm is connected to the second lateral side of the support assembly and configured to connect to a second section of the thrust reverser. The first arm and the second arm are pivotally connected to the support assembly to support the first section and the second section of the thrust reverser at different angular positions.
