ETC Forms New Composites Group

SOUTHAMPTON, Pa., Nov. 10 - Environmental Tectonics Corporation (Amex: ETC) (ETC), an internationally positioned developer and manufacturer of state-of-the-art flight simulators, aircrew trainers, centrifuges, aero-medical equipment, and motion-based, virtual reality type entertainment systems has announced the formation of ETC High Performance Composites. The key resources of the former ARDCO Composites (Advance Ratio Design Company, Inc.) of Chester, PA have joined ETC and will form the technical and management core of the new group. Over its nearly forty-year history, ARDCO earned a well-deserved reputation as a pioneering contributor to the advanced materials technologies. Among many other significant "firsts", they developed and manufactured the first all-composite propeller blade certified by the FAA for use on a commercial airliner (the CASA C-212). Over the past ten years the ETC High Performance Composites team has developed inventions and processes which make possible the molding of massive, high- strength composite material structures previously considered to be impractical or impossible, such as the primary landing gear beams for heavy-lift helicopters.

Carl L. Aley, President of ETC High Performance Composites, has over thirty years of design, engineering, and management experience, with a heavy concentration in advanced materials technologies. He holds numerous U.S. patents in the aviation, industrial, and nuclear power industries and served as President of ARDCO since 1985.

Robert B. Henstenburg (Ph.D Cornell, 1988), former Chief Engineer of ARDCO, is Chief Engineer of High Performance Composites. Dr. Henstenburg is a recognized authority in the very specialized technology of modeling and analyzing fiberously reinforced composite material structures. He is responsible for material modeling, structural design, analytical evaluation (including FEA) and customizing software packages to allow/improve computational capability.

According to William F. Mitchell, ETC's President and CEO, "ETC is very fortunate to have acquired this important capability. It is a timely acquisition, especially in relation to our entertainment products, which have such a great potential for the use of composite materials because of their demand for very unique shapes and extremely high strength - as well as lower cost of manufacture. Carl Aley and Rob Henstenburg bring their unrivaled breadth and depth of experience to this new group. They fit in perfectly with our long-range plans."

For nearly 30 years, ETC has been on the leading edge of the design, manufacture, installation, training and long-term maintenance of its products in the U.S. and 65 countries worldwide. These products include: aircrew training systems for standard and high-performance aircraft; disaster management simulators; industrial sterilization equipment and environmental simulation systems; clinical hyperbaric systems, entertainment/amusement systems; and related hardware and software products. ETC's main plant and offices are located in Southampton, PA, USA, with subsidiary locations in Orlando, FL, the UK, Warsaw, Poland and Ankara, Turkey.
