Boeing 757

Jet Brella Boeing 757 Engine Covers

Jet Brella’s purpose-built engine cover system for the Boeing 757 provides comprehensive inlet and exhaust protection for aircraft powered by the Rolls-Royce RB211-535E engines. Designed for maximum defense during ground operations, storage, or extended maintenance, these high-performance covers shield vital engine components from foreign object damage (FOD), environmental hazards, and weather extremes. Compatible with all 757 variants, including BBJ adaptations, the complete cover kit (Part Number JB-RB211-535E-KT) is engineered to deliver superior reliability, reduced maintenance burden, and optimal operational readiness.

Inlet Covers

Jet Brella’s inlet covers for the Boeing 757 conform precisely to the RB211-535E engine nacelle, creating a tight, protective seal against airborne debris, moisture, wildlife, and ramp dust. Each cover includes a trampoline valve venting system that relieves backpressure and maintains internal airflow. At just 13 lbs. each and measuring 52.5” high by 12” wide in the stowed position, these lightweight yet durable covers are easy to handle and quick to install. Snap fasteners and quick-release pins make tool-free application effortless for one person. The glass fibre cone adds strength without weight, and every set comes with a breathable mesh carry bag, complete with loops for vertical stowage.

Exhaust Covers

Jet Brella’s exhaust covers for the 757 offer essential protection for the RB211-535E’s aft exhaust outlets. With a precise fit and robust construction, these covers guard against sand, nesting birds, snow, and rain, particularly during extended downtimes. Each cover is built with a fiberglass cone lined in neoprene foam, adding thermal and environmental resistance. The system uses a polycarbonate cantilever attachment with GSE bolts, ensuring firm installation that stands up to jet wash and wind. Measuring 44.5” in height by 18” in width (stowed) and weighing 13 lbs. each, these units are easily managed by ground personnel and designed for safe, rapid deployment.

Dual Venting Engine Covers for 757

Hi‑Flow Dual Venting Inlet Cover

• Engine-Specific Fit: The inlet and exhaust covers are molded to perfectly match the aerodynamic form of the RB211-535E engine, maintaining performance integrity and preventing damage during inactive periods.

• Venting System:

  • Trampoline-style pressure relief valves open automatically to equalize internal pressure from residual heat or ambient change.

  • Mesh-free airflow channels maintain consistent ventilation, minimizing condensation and internal humidity buildup.

• Protective Capability:

  • Prevents internal moisture accumulation, windmilling, and external damage from contaminants.

  • Ideal for use in snow-prone, coastal, or desert environments.

  • Best results when inlet and exhaust covers are used together.

• Installation & Security:
  

  • Snap/quick-release hardware for inlet covers; bolt/cantilever for exhaust units.

  • All components are tool-free and require no aircraft modifications.

  • Engineered to resist high winds, ramp turbulence, and precipitation.

• Convenience & Storage:

  • Compact stow dimensions and carry bags with mesh and vertical storage loops.

  • Fiberglass cones ensure lightweight durability.

  • Neoprene foam lining in exhaust covers adds thermal protection.

• Customization:

  • Available in a range of colors with optional mesh configurations.

  • Add custom tail numbers, aircraft IDs, or company logos via embroidery.

  • Variants available for specialized use (e.g., low visibility, desert ops).

Jet Engine FOD Damage Protection for 757

Built for Classic Performance

Jet Brella’s engine cover kit for the Boeing 757 offers high-level protection against FOD threats including salt spray, sand, snow, ice, birds, and maintenance debris. Ideal for carriers operating in extreme climates, the system helps prevent costly damage to fan blades, guide vanes, and internal engine components.

Weather Shielding

• Shields against moisture, precipitation, and environmental corrosion.

• Supports cold-weather operations by preventing ice buildup inside engine chambers.

• Maintains dry, contaminant-free engine interiors during all ramp conditions.

Operational Safety

• Clearly defines engine zones, reducing risks during ramp movement or maintenance.

• Prevents accidental ingestion of tools or ground debris.

Anti‑Corrosion Benefits 

• Blocks moisture, pollutants, and salt air from reaching engine internals.

• Reduces oxidation and helps extend overall engine lifespan and performance consistency.
