Thiokol Successfully Tests Technology Demonstration Motor

Brigham City, Utah--November 16, 2000-- Thiokol Propulsion, an Alcoa business, today successfully test fired a 92" diameter, 120,000 pound class demonstration motor with new propellant, case, nozzle and control technologies. "The test is an important milestone for Thiokol, the Deputy Under Secretary of Defense's Science and Technology group, and the Air Force since it demonstrates a major improvement in performance while simultaneously reducing the cost," said Michael Blair, manager of Propulsion Technology Business Development.

The test is the culmination of a 23-month, jointly funded program by the Air Force Research Laboratory Propulsion Directorate and Thiokol to demonstrate the Phase I Integrated High Payoff Rocket Propulsion Technology (IHPRPT) goals. The IHPRPT program is a three-phase, government and industry coordinated effort that began in 1996 with the vision to double the propulsion capability by 2010. It has been cited as a model of government and industry partnership in research and development.

"The demonstrated technologies are ready to be transitioned into small and large launch vehicles as stages or strap-on boosters, and defense missiles. If all the technologies were incorporated into a small launch vehicle, the cost-per-pound to orbit would be reduced by approximately 30 percent," explained Steven Glaittli, Phase I Program manager. Thiokol and the Air Force are continuing to pursue solid propulsion improvement with initiation of the Phase II Demonstrator Program scheduled for completion in 2004.

Alcoa (AA-NYSE) is the world's leading producer of primary aluminum, fabricated aluminum and alumina. Alcoa has over 300 operating locations in 36 countries. Thiokol Propulsion, part of the Alcoa Industrial Components group, is the leading manufacturer of solid propulsion systems for space and defense.
