Siemens Energy has recently opened a facility in Charlottesville, Virginia for
the innovative commercial production of airfoil ceramic cores for gas turbine
blades and vanes using the TOMO^SM technology, initially developed by Mikro
Systems, Inc. The advancements are expected to improve the cooling capability
of gas turbine blading, thus enabling higher levels of engine performance and
efficiency for future Siemens Gas Turbines. This technology is available to
Siemens as a part of the Technology License agreement with Mikro Systems.

With support from the U.S. Department of Energy (DOE) and the American
Recovery and Reinvestment Act (ARRA), Mikro Systems was funded via Small
Business Innovation Research (SBIR) grants. Mikro Systems and Siemens Energy
partnered to develop the application of its patented Tomo-Lithographic Molding
(TOMO^SM) manufacturing technology to a range of gas turbine components.

“Through our licensing agreement with Mikro Systems, we are developing for
commercial application the TOMO^SM technology that is good for the environment
as well as for our customers’ budgets,” said Randy Zwirn, president and CEO of
Siemens Energy, Inc. and CEO of the Energy Service Division. “It provides us
with a game changing enabling technology to further boost our current world
record for combined cycle efficiency of almost 61 percent to even higher
levels.” Through retrofitting, the new technology can also be applied for
improving the efficiency of power plants already in operation.

“Over the past few years, we’ve begun developing advanced components based on
our TOMO^SM technology. Through our successful collaboration with Siemens, our
technology will be responsible for tremendous progress in blade
manufacturing,” states Mike Appleby, CEO and founder of Mikro Systems.

“Fundamentally, this manufacturing technology opens the airfoil design space
in ways thought unfeasible only a few years ago,” said Thierry Toupin, CEO of
the Products Business Unit of the Fossil Power Generation Division of Siemens
Energy. “As such, it represents a critical tool in Siemens’ clean energy
product development efforts.”

Gas turbines, which are used to produce power for industrial, utility, and
aerospace applications, consist sequentially of compressor, combustor, and
turbine sections. Incoming air is compressed to a high pressure state in the
compressor section, and heated to high temperature via the combustion of fuel
in the combustor section. The high-temperature, high-pressure gas is then
expanded through a series of rotor-mounted airfoils in the turbine section,
converting the gas’ energy into mechanical work. Therefore, improved airfoil
designs which can tolerate higher gas temperatures and use less cooling air,
result in the highest level of efficiency in natural gas turbine energy
production.
