Frequently Asked Questions
What is the purpose of an engine exhaust barrier?
An engine exhaust barrier is designed to seal and protect the exhaust outlets of an aircraft engine during storage, maintenance, and ground handling. These covers help prevent moisture, debris, pests, and environmental contaminants from entering the exhaust system.
This protection reduces the risk of corrosion and foreign object damage (FOD), which can compromise engine performance or lead to costly repairs. Sesame Technologies’ exhaust barriers provide a snug, weather-resistant seal to maintain engine integrity across all conditions. They are essential tools for any operator looking to preserve engine health during downtime.
How do Sesame engine exhaust barriers help prevent FOD?
Sesame engine exhaust barriers act as a physical shield against foreign object debris (FOD), which is a leading cause of engine damage during ground operations. By covering the exhaust ports, these barriers block the entry of dust, small objects, and environmental debris that could otherwise settle inside the engine.
The tight seal ensures nothing bypasses the barrier during aircraft storage or servicing. This proactive protection helps maintain operational safety and reduces the need for post-storage inspections and cleanings. In high-traffic ramp environments, they are especially effective in preventing incidental contamination.
Are Sesame engine exhaust barriers suitable for all weather conditions?
Yes, Sesame Technologies’ engine exhaust barriers are built with weather-resistant materials to ensure dependable protection in all climates. Whether your aircraft is stored in hot, cold, humid, or storm-prone environments, these covers provide a durable seal against the elements.
The materials resist UV damage, moisture penetration, and temperature-related wear. This makes them ideal for both short-term ramp exposure and extended outdoor storage. Operators can rely on them to maintain engine cleanliness and condition regardless of environmental challenges.
What aircraft types are compatible with Sesame exhaust covers?
Sesame engine exhaust barriers are compatible with a wide variety of business jets, commercial aircraft, and military platforms. Each exhaust cover is custom-designed or available in multiple sizes to accommodate different engine configurations and exhaust geometries.
Whether you're working with turbofan, turboprop, or specialized propulsion systems, Sesame has a solution to match. PJi’s support team can assist in identifying the right product for your exact aircraft model. This ensures a secure fit and maximum protection for every application.
How are Sesame engine exhaust barriers installed?
Sesame exhaust barriers are engineered for quick, easy installation to reduce technician workload and improve safety. Most covers are designed to slip over or insert into the exhaust outlet, with integrated securing features such as straps, drawcords, or rigid inserts.
The precision-fit construction ensures a tight seal without damaging surrounding surfaces. Installation typically requires no special tools, and removal is just as simple. These features make Sesame barriers an ideal choice for fast-paced maintenance environments and mobile operations.
Can engine exhaust covers be used during aircraft maintenance?
Yes, Sesame Technologies’ engine exhaust barriers are widely used during maintenance procedures to prevent internal contamination. While technicians are working on other systems or performing routine inspections, the exhaust covers keep debris and contaminants from entering exposed engine components.
This reduces the risk of post-maintenance failures and maintains a clean engine interior. They also support compliance with standard MRO cleanliness protocols. For routine or heavy maintenance, they’re a smart addition to your ground support equipment.
How do engine exhaust barriers support long-term aircraft storage?
During long-term aircraft storage, exhaust openings are vulnerable to corrosion, animal intrusion, and moisture accumulation. Sesame engine exhaust barriers provide a sealed, protective layer that prevents these threats from affecting the exhaust system and connected components.
Their durable construction holds up over time, ensuring consistent protection without degradation. These covers are especially valuable in outdoor storage scenarios or in environments with extreme weather fluctuations. Using them helps preserve engine condition and simplifies the reactivation process when the aircraft returns to service.
What materials are used in Sesame exhaust barriers?
Sesame Technologies uses rugged, aviation-grade materials that are resistant to UV damage, precipitation, dust, and temperature swings. The outer layers are often made from reinforced vinyls or heavy-duty fabrics, while the interior liners provide a soft, non-abrasive surface to protect engine components.
These materials are selected to ensure long-lasting performance even under repeated use. Their resilience makes them suitable for both indoor hangar storage and challenging ramp conditions. Overall, these materials balance strength with protective cushioning for sensitive engine parts.
What are the benefits of using exhaust barriers in ground support?
Using engine exhaust covers as part of your ground support strategy offers several key benefits. They help maintain engine cleanliness, reduce wear caused by environmental exposure, and prevent costly damage from debris or water ingress.
Exhaust covers also support compliance with FOD prevention protocols, making them essential for airport ramp operations and MRO facilities. Their ease of use saves time during aircraft handling and reduces the need for secondary cleaning or inspection. This translates into smoother, safer, and more efficient maintenance cycles.
