TEWKSBURY, Mass., May 3, 2007 -- Raytheon Co. was recently awarded a
$7.5 million contract to develop an improved composite material for
infrared windows and missile domes by the Defense Advanced Research
Projects Agency (DARPA).
The
two-year contract calls for the development of "significantly enhanced
materials and manufacturing processes compared to those currently in
use for windows and aerodynamically shaped domes in the 3 to 5-µm
midwave infrared band," said Mark Russell, vice president of
engineering at Raytheon's Integrated Defense Systems.
The
Phase 1 contract is being performed for the Office of Naval Research as
part of DARPA's Nano-Composite Optical Ceramics program. The objective
is to develop a processing method for the manufacture of infrared
transparent missile domes capable of higher-speed operation and greater
particle impact resistance than sapphire, the current material. If
options are exercised in subsequent phases, the full program has a
potential value of $14.4 million.
Phase 1 goals include
achieving midwave infrared optical transmission exceeding that of
spinel with mechanical properties greater than those of sapphire," said
Rick Gentilman, Raytheon's program manager. "These efforts will include
the development of new classes of infrared materials for windows and
domes based on multiphase nanocomposites designed to be substantially
stronger than existing single-phase infrared materials."
Joining
Raytheon's project team are Rutgers University, the University of
Connecticut, the University of California-Davis and three small
businesses -- Nanocerox, an Ann Arbor, Mich., producer of mixed-metal
oxide spherical nanopowders; CeraNova, a Marlborough, Mass., maker of
electroceramic composites for smart materials systems; and CBW Tech
Services of Framingham, Mass.
Raytheon's work on the contract
will be performed by its Integrated Defense Systems in Andover, Mass.,
and by Missile Systems in Tucson, Ariz.
