Short Take: Sikorsky uses SGI for stealth calculations

Sikorsky Aircraft has selected SGI to help develop stealth technology on the upcoming RAH-66 Comanche armed reconnaissance helicopter, SGI said today. In February, Sikorsky installed a 128-processor Origin 2000 computer with 32 GB of memory. SGI, meanwhile, last week introduced a new Origin 3000 series with higher performance. Stealth calculations for helicopters are more difficult than for airplanes because a helicopter's rotors swivel and rotate, drastically increasing the number of possible radar reflections.
