RAH-66 Hardware Design and Sensor Development

Boeing is the world’s largest aerospace company and leading manufacturer of commercial jetliners, defense, space and security systems, and service provider of aftermarket support. As America’s biggest manufacturing exporter, the company supports airlines and U.S. and allied government customers in more than 150 countries. Boeing products and tailored services include commercial and military aircraft, satellites, weapons, electronic and defense systems, launch systems, advanced information and communication systems, and performance-based logistics and training. The company continues to expand its product line and services to meet emerging customer needs.

Occam Technology Group was approached by Boeing to design the RAH-66 helicopter. The RAH-66 is a stealth attack helicopter incorporating multiple techniques in order to reduce its radar cross-section (RCS) and other areas of visibility. Its outer surfaces are faceted and have radar-absorbent material (RAM) coatings and infrared-suppressant paint applied; with these measures, the Comanche’s RCS is 360 times smaller than the AH-64 Apache attack helicopter. The Comanche’s noise signature is noticeably quieter than comparative helicopters; this is partly achieved through the all-composite 5-blade main rotor and tail rotor assembly. Occam Technology Group performed Hardware/firmware design and development of analog sensor conditioning, digital signal processing, and validation.
