FRCE moves into future with new helicopter blade balancing system
Rotor blades for the CH-53K King Stallion helicopter that arrive for rework at Fleet Readiness Center East (FRCE) will be balanced on a new system that will save about $18 million by eliminating the need for building a new testing facility.
Helicopter rotor blades must be balanced to reduce vibration that can place stress on the helicopter’s airframe. At FRCE, this balancing process has traditionally been performed using the facility’s Helicopter Blade Balance Facility, commonly known as a whirl tower, to simulate the blade’s performance in flight.
