Canopy/Cockpit/Fuselage Covers:
The Bell 47 Bubble Cover protects the entire canopy—including the windshield, skylights, and chin bubble—helping prevent damage from heat, leaks, debris, vandalism, and theft while reducing wear on upholstery and avionics. Made from Silver Acrylic Sunbrella canvas and fully lined with soft microfiber, the reflective, breathable cover is water-, ice-, snow-, and UV-resistant while preventing scratches. Features include reinforced patches at hinges, door handles, and windshield wipers, rope-hemmed top and bottom edges to prevent chafing, color-coded corners for easy installation, non-metal Delrin buckles, and sewn-in pockets for temperature probes and pitot tubes. The medium-weight material is treated for UV, water, and anti-static resistance, and tests show it can reduce cabin interior temperatures to near-ambient levels on the hottest days, while remaining breathable to allow moisture to escape.
Engine/Prop Covers:
Blade Tie-Downs for Bell 47 Models are "socks" that fit over rotor tips, securing with ropes or straps to the front cross tubes or any convenient point, while Rotor Hub Covers overlap Blade Covers for complete main rotor protection. Medium-weight Solution-Dyed Polyester Blade Covers cinch at the root with quick-release buckles and can be installed from the ground using a lightweight rope; Cold Weather Blade Covers include full-length zippers and optional deice “boots” for preheater systems. Engine Covers protect the swash plate, inlets, exhaust, and access areas, fastening securely around the rotor mast and tailboom with straps and Delrin buckles, while Insulated Engine Covers add 3M Thinsulate and soft nylon lining to retain heat and support preheating. Tail Rotor Covers are one-piece designs enclosing both blades and hub. All covers are available in durable Silver Acrylic Sunbrella for year-round use or lighter Solution-Dyed Polyester for seasonal or occasional outdoor use, providing reliable protection from sun, moisture, and cold weather.
Plugs and Protection:
Bell 47 Models Pitot Tube Covers (non-heat resistant) are made from durable Naugahyde vinyl and slip over the entire pitot assembly, securing at the base with a Velcro strap and including a “Remove Before Flight” streamer. Heat-resistant versions are available to prevent melting if the pitot heat is accidentally activated, and tethered sets can be requested for added convenience.
Wing/Tail/Empennage Covers:
Tailboom Covers vary by model but generally enclose the tail boom from the “bottleneck” to the aft end and often extend over the horizontal stabilizers. They are custom-made to accommodate antennae, lights, and other protrusions, and attach securely with straps underneath the tail boom. Separate covers for vertical and horizontal stabilizers are also available, with model-specific details provided on request.
Miscellaneous Products:
Padded Door Bags provide portable protection for aircraft doors when removed. Each bag is moderately padded, features a zippered closure, and includes sturdy carry handles for easy transport.
Light Weight Travel Covers:
The Bell 47 Models Lightweight Travel Bubble Cover mirrors the standard bubble cover design but uses very lightweight Silver Solution-Dyed Polyester fabric, allowing it to fold compactly for easy storage. Fully lined across the entire cover, the material is water-resistant and ideal for occasional outdoor use, while an ultra-lightweight option is available for fitted hangar dust covers. For daily outdoor protection, the non-travel Sunbrella Cover is recommended.
