Solution Overview
Problem
Current fire protection systems for gas turbine engines face challenges in effectively containing and preventing the spread of fires within engine compartments, particularly in meeting regulatory standards for flame resistance and fire containment.
Innovation Solution
A fire protection system comprising a fire blanket with attachment systems such as hook and loop, slot and wedge, protrusion and hole, and hook and hole systems, designed to securely attach fire blankets to fairing walls within the engine compartment, ensuring effective containment of fire and prevention of flame spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire seals are used to seal between adjacent components, then fire containment is improved, but the complexity of the system increases
Solution Approach 1:
A fire blanket is introduced as an intermediary component between the fire seal and the fairing wall. The fire blanket serves as a sacrificial protective layer that absorbs fire damage and prevents direct exposure to the fire seal and underlying structures, thereby enhancing fire containment while maintaining relatively simple sealing components
Solution Approach 2:
The fire protection system is segmented into multiple functional layers: the fire seal provides the primary sealing interface, while the fire blanket provides secondary protection. This segmentation allows each component to perform its specific function optimally without requiring the entire system to be overly complex
2Reliability
If fire blankets are employed to protect panels, then fire resistance is improved, but the attachment complexity increases
Solution Approach 1:
Attachment features (hooks, loops, slots, wedges, protrusions, holes) are pre-integrated into the fire blanket and fairing wall structures during manufacturing. This preliminary action eliminates the need for separate attachment operations during installation, reducing on-site complexity while maintaining secure attachment and fire resistance
Solution Approach 2:
The attachment system is designed with universal features that can be configured in multiple ways (hook-and-loop, slot-and-wedge, protrusion-and-hole) to accommodate different installation scenarios and fairing wall configurations, providing flexibility without increasing fundamental system complexity
