Kaman Helicopters Delivers 1,000th BLACK HAWK Erosion Protection Coated Main Rotor Blade

BLOOMFIELD, CT, June 08, 2010 ¡X Kaman Helicopters has delivered the 1,000th helicopter rotor blade protected with Kaman¡¦s erosion-resistant coating system. U.S. Army BLACK HAWK helicopters are utilizing main rotor blades with Kaman¡¦s innovative coating system and have reported significantly improved blade life, increased aircraft availability and reduced maintenance requirements.

The latest erosion-resistant blade delivery defines another successful chapter in Kaman¡¦s ongoing support of U.S. war fighters around the world. The program has been in production for more than two years with a flawless quality assurance record.

As the only U.S. company certified to apply Hontek sprayable protective coatings to rotor blades, Kaman has improved the operational effectiveness of U.S. Army BLACK HAWK helicopters flying in the harsh desert environments of Iraq and Afghanistan where sand can cause damage to the leading edges of helicopter blades during rotation. Coated rotor blades operate effectively in rain, sand, gravel and icing conditions, and worn coatings can easily be repaired in the field. After reviewing the system¡¦s proven performance with the U.S. Army, the Naval Air Systems Command is qualifying the coating process for use on U.S. Navy and Marine Corps helicopters.

Kaman has invested heavily in infrastructure and equipment at its HeliworX㤠subcontracting facility to support the rotor blade protection program and to develop its world-class design, development, manufacture and repair of composite rotor blades.
