Products

VHA product lines include composite main rotor blades for the Bell 206B3 JetRanger and composite tail rotor blades for the 206B3/206L series/OH-58, and various models of the UH-1 Huey. Operators in 15 countries around the world have equipped their rotorcraft with VHA blades for use in such varied industries as tour operations, law enforcement, fire fighting, agricultural and commercial/civil applications.

 

206B Main Rotor Blade

The VHA 206B main rotor blades use the same carbon fiber materials and construction methods similar to the company’s successful 206B/L tail rotor blades, which have been available as an STC/PMA aftermarket component since 2009.

  • Carbon fiber skin and spars increase strength and minimize corrosion.
  • An efficient NASA-designed laminar-flow airfoil provides greater speed at the same power settings (according to customer field reports; not yet confirmed by VHA).
  • Stainless steel and nickel abrasion strips cover the entire length of the blade for erosion and lightning strike protection.
  • A single trim tab facilitates the track-and-balancing process.
  • The VHA blades use the identical installation configuration as the OEM blades, allowing direct replacement without hub modification.
  • An 18,000-hour service life and pricing similar to the OEM metal blades means that your direct operating costs are lowered by more than half over the life of the blade.

 

206/OH-58 Tail Rotor Blade

If noise is a concern in your neighborhood, fly neighborly with VHA tail rotor blades. VHA’s composite 206/OH-58 tail rotor blades can lower the overall aircraft noise by up to 40%, according to FAA-approved acoustics testing. The noise reduction comes from a thinner NASA-designed laminar flow airfoil and shaped tip that cut through the air more efficiently than previous designs.

  • Carbon fiber skin and spars increase strength and minimize corrosion.
  • An efficient NASA-designed laminar-flow airfoil provides more tail rotor authority at higher altitudes and greater lift capability (new charts published in the 206L series Flight Manual Supplements).
  • Nickel abrasion strip and Astrostrike mesh cover the entire length of the blade for erosion and lightning strike protection.
  • A titanium root fitting and stainless steel pitch bearings provide more strength and durability at the root/hub connection.
  • The VHA blades use the identical installation configuration as the OEM blades, allowing direct replacement without hub modification.
  • A 5,000-hour service life (double the life of the OEM metal blades) means that your direct operating costs are lowered by nearly half over the life of the blade.

 

UH-1 Huey Tail Rotor Blade

If you’re still flying metal blades, experience the difference new technology can make on your UH-1. VHA’s composite UH-1 tail rotor blade uses an advanced cambered airfoil that improves stall margin, increases tail rotor authority and decreases vibration.

The VHA UH-1 tail rotor blade features carbon fiber spar and skins, fiberglass root fittings, and a stainless steel abrasion strip. The all-composite construction results in a lighter but stronger rotor blade that resists both corrosion and impact damage. Although VHA’s UH-1H tail rotor blade is nearly one-inch wider than the OEM blade, no modification to the tail rotor hub is required for installation.
