Auburn, AL - Archangel Systems, Inc. announced today that Bell Helicopter Textron of Fort Worth, TX has entered into a long term agreement with Archangel, under which Archangel will supply its Air Data Attitude Heading Reference System (AHR150A) for the Bell/Agusta Model 609 Tilt Rotor Aircraft. Three AHR150A Systems will be used in each 609 as part of the aircraft’s fly by wire system.

Archangel’s AHR150A, selected by Bell, provides ARINC 706-4 Air Data on 4 ARINC 429 Lo-Speed busses and ARINC 705-5 Attitude Data on 4 ARINC 429 Hi-Speed busses. Each AHR150A system is comprised of two boxes, an Inertial Sensing Unit (ISU) and a remotely mounted three axis Magnetic Sensing Unit (MSU). The ISU contains multiple dissimilar software and processors to achieve true DO178b Level A performance with MEMS sensors. Certification of the unit is expected in December of 2006, with deliveries starting in the first quarter of 2007.

The heart of the AHR150A inertial sensing is a commercial version of the IM3 (Inertial Measurement Cube) and is based on Archangel’s proprietary FLASP software. The IM3 is being provided in varying configurations for a variety of guidance and control systems, image stabilization systems, and other applications.

The Bell/Agusta 609 is the world’s first civilian Tiltrotor aircraft. The BA609 Tiltrotor combines the speed, altitude, and comfort of a turboprop with the vertical takeoff and landing capabilities of a helicopter. Having cruising capabilities of 25,000 ft., this versatile aircraft will fly in icing conditions and extreme climates, from Arctic to desert. Seating up to nine passengers and at twice the speed of typical helicopters of comparable capacity, the BA609 is designed to be the best multi-mission aircraft for the task.

Jack Gallagher, Program Director for Bell/Agusta 609, expressed the importance of the long-term agreement, "Key to the success of the 609 is cost, performance, weight and schedule; Archangel Systems meets these critical elements and we welcome them to our Team."

"Archangel was founded to improve inertial sensing and navigation systems while at the same time reducing costs" said Archangel’s president Kitty Greene. "Bell’s selection makes it clear that Archangel is achieving that goal."
