MSC.Software Announces MD Nastran Rotor Dynamics Success

MD Nastran Rotor Dynamics Improves Propulsion System Analysis and Reduces Time-to-Solution for Jet Engine and Airframe Manufacturers

SANTA ANA, Calif., July 6 /PRNewswire-FirstCall/ -- MSC.Software Corp. (OTC: MNSC), the leading global provider of enterprise simulation solutions including simulation software and services, and Boeing Commercial Airplanes announced today MD Nastran Rotor Dynamics has successfully met its two-year goal to provide an industry standard for rotor dynamics simulation. MD Nastran Rotor Dynamics provides the standard that allows aerospace jet engine and airframe manufacturers to cut time-to-solution and improve analysis collaboration.

MD Nastran Rotor Dynamics is a cooperative effort between NASA, Boeing, major Boeing partners, and MSC.Software to enable collaboration between jet engine and airframe manufacturers.

"When you look at the requirements of a rotor dynamics code, such as blade out simulation, there are no other codes in the world that can perform this combination of analysis," said Dr. Charles Lawrence, structural engineer, Structures and Acoustics Division, Glenn Research Center at Lewis Field, NASA. "These models are incredibly large -- millions of degrees of freedom. MD Nastran is the only code that can take these large models and abstract them to smaller models and still produce accurate results. This is the industry-standard solution aerospace companies are using and will continue to use in the future to come up with better answers when designing propulsion systems."

"With a fully integrated linear and nonlinear solution MD Nastran provides the capability to simulate short-duration explicit events such as bird-strike and blade-out with rotor dynamic simulations. MD Nastran makes it possible to simulate Propulsion System dynamics behavior such as rotor unbalance, blade out and other critical conditions at a small fraction of the cost of a single physical test," said Reza Sadeghi, Vice President of Product Development for MSC Software. "MD Nastran Rotor Dynamics provides an industry standard, which allows collaboration between jet engine manufacturing partners and air frame manufacturers, reducing the silos of simulation technology that exist within today's enterprise environment, to further improve propulsion system analysis reliability."

"More than ever, today's manufacturers seek to improve the richness of the complex propulsion system simulation process to provide even greater representation of the physical world scenarios simulated today," said Technical Fellow Mohammad Heidari, Boeing Commercial Airplanes Propulsion technology. "MD Nastran Rotor Dynamics provides an integrated solution that will further help manufacturers to better predict, and help reduce the number of physical tests they currently conduct to develop and certify propulsion systems."

Propulsion system design is a collaborative process, requiring model and results accuracy. Propulsion system and airframe manufacturers had been using home-grown codes coupled with Nastran, which required significant effort to compare simulation results from different models. MD Nastran Rotor Dynamics reduces the time-to-solution compared to single point tools used for such multidiscipline applications because customers work with a common model instead of multiple models for each type of analysis. The ability to perform standardized analyses and exchange a common model results in much higher productivity and fewer bottlenecks.

About Boeing Commercial Airplanes

Boeing has been the premier manufacturer of commercial jetliners for more than 40 years. With the merger of Boeing and McDonnell Douglas in 1997, Boeing's legacy of leadership in commercial jets, joined with the lineage of Douglas airplanes, gives the combined company a 70-year heritage of leadership in commercial aviation. Today, the main commercial products are the 737, 747, 767 and 777 families of airplanes and the Boeing Business Jet. New product development efforts are focused on the Boeing 787 Dreamliner, a super-efficient airplane that is expected to be in service in 2008. The company has nearly 12,000 commercial jetliners in service worldwide, which is roughly 75 percent of the world fleet. Through Boeing Commercial Aviation Services, the company provides unsurpassed, around-the-clock technical support to help operators maintain their airplanes in peak operating condition, and Commercial Aviation Services, which offers a full range of world-class engineering, modification, logistics and information services to its global customer base, which includes the world's passenger and cargo airlines, as well as maintenance, repair and overhaul facilities. Boeing also trains maintenance and flight crews in the 100-seat-and-above airliner market through Alteon, the world's largest and most comprehensive provider of airline training.
