Erickson Incorporated has announced final FAA certification for the composite main rotor blades on the S-64F and CH-54B helicopters. Earlier this year, the company received approval for the S-64E model. This recent announcement finalizes the certification of the S-64F and CH-54B, solidifying FAA certification for the entire fleet of S-64 Air Crane® E & F models, as well as the CH-54 Skycrane A & B models.

The advanced design of the blades provides a significant performance advantage, especially with hot and high conditions.

This Certification brings considerable advantages, such as:

  • Performance gains
  • Fuel savings
  • Reduced vibration, meaning reduced wear and fatigue on the entire aircraft
  • Blade interchangeability with the E/A models
“It was quite difficult, but extremely satisfying to see this
project through to completion. There are a lot of blood
sweat and tears in those blades.”
– Billy Johnson, Chief Engineer at Erickson Incorporated

  1. Questions from a dummy-
    Are the new blades carbon fiber?
    Were the old blades aluminum or an alloy thereof?

    1. “An advanced composite blade construction for a helicopter rotor blade using for the most part fiber reinforced plastic materials in which the major assembly of blade elements is a single step co-cure operation and in which an integral spar/skin carries centrifugal, flapwise and chordwise loads and also incorporates redundant means to carry torsional loads and a honeycomb core carries shear and aerodynamic pressures loads.”
      —————————————-End of quote —————————-
      Notice that the above is (wow!) one sentence!

      Plastic reinforced materials are as follows:

      glass
      Carbon
      aramid
      Basalt

      As far as I can find rotor blades for the S-64 were made of aluminum. No mention of alloys.
