PTC's Flexible Engineering and CPC Solutions Reduce Costs and Cut Time

To Market By As Much As 50 Percent

PTC (Nasdaq:PMTC), a leading provider of collaborative product commerce (CPC) solutions, today announced its continued success within the aerospace/aviation industry. Leading aerospace and aviation companies choose PTC's mechanical computer aided design (MCAD) and Internet-based collaborative product development solutions to enhance their competitiveness. To illustrate PTC's selection by top aerospace and aviation companies, PTC will showcase today various organizations that have purchased and prospered with PTC solutions.

"As we approach the centenary of aviation, the pace of technological change in the industry is unprecedented," said Barry Cohen, executive vice president of marketing at PTC. "This leads to new challenges for the industry, from demand fluctuation to geographical diversification, all with the same heightened focus on lowering costs and shortening time-cycles. With Flexible Engineering and CPC solutions, PTC is uniquely positioned to support the aerospace industry in meeting these challenges - whether related to design, workflow or collaboration."

Currently, PTC's products are used to develop and test products ranging from satellites to commercial, military and corporate aircraft, to crew vehicles for NASA. With PTC's MCAD products, companies can drastically reduce their engineering design cycle times, rapidly explore multiple design solutions, minimize physical prototypes and leverage their existing design knowledge to create more innovative products. With PTC's Internet-based collaborative product development solutions, including Windchill, companies can communicate and collaborate effectively with other divisions or companies worldwide, without sacrificing the security or integrity of the design data.

"A major challenge in the spacecraft business is finding a powerful modeling tool that allows our engineers to simultaneously access key information. Of all the tools available, PTC provided the best solutions," said Michael Mongilio, CAE applications engineer at Swales Aerospace, a PTC aerospace customer. "In designing spacecraft, we have to know the product we design is exactly the product that we are going to fly. With PTC's solutions, we can trust the reliability and integrity of the product data, and are assured the end product is precisely what we see on our computer screens."

Implementing PTC solutions radically decreased the Aerojet X-38's time to market. "Our latest project, the deorbit propulsion stage of the X-38 Crew Return Vehicle, could easily have been a four-year, $2 billion project," said Jim Hanson, engineer for Aerojet. "With the help of PTC's solutions, we cut our time-to-market by 50%, allowing us to design, build and test-fly two prototypes in space for just $90 million."

"To compete successfully in today's aerospace marketplace, companies are focusing on more than just cost-cutting measures," concluded Cohen. "They are leveraging the collaborative abilities of the Web. By leveraging the enhanced communication that the web provides throughout all phases of a product's lifecycle, connecting all members of the value-chain, these companies create `virtual corporations' to meet the market's demands. PTC's solutions overcome the barriers of collaborating among heterogeneous environments, whether among a company's different departments or divisions, or with outside customers, partners or suppliers. Collaborating among all members of the value-chain allows a company's core team of design engineers to focus on their most important mission: continuously designing new, innovative products to stay ahead of the competition."
