Republic, Poland and Turkey, as well as external partners. One of
the GE AAT Munich-led partnerships is the Turbine Technology
Project (TURN), which was set up to accelerate technology maturation
for future aero engines.
And in response to a Clean Sky 2 call for proposals, in 2018
a consortium of Hamburg University of Technology (TUHH),
TU Dresden (TUD) and technology company Autodesk, was
selected to support GE AAT Munich for the design and manufacturing
of a large-scale metal additive manufacturing component
- the Advanced Additive Integrated Turbine Centre
Frame (TCF) casing - the MONACO project. This also included
the design and production of coupons and critical parts,
validation and qualification, and the final delivery of the fullsized
metal 3D-printed casing.
After almost six years in R&D and engineering, the large-format
TCF casing design using GE Additive's Direct Metal Laser
Melting (DMLM) technology in nickel alloy 718 was recently
unveiled by the consortium. The TCF casing is one of largest
additively manufactured parts produced for the aerospace
industry. The additively manufactured TCF casing is designed
for narrow-body engines in which the part is approximately
one meter or more in diameter.

armin International, Inc., a unit of Garmin Ltd., has
announced the selection of its G3000 tandem integrated
flight deck as part of a U.S. Special Operations Command (USSOCOM)
Armed Overwatch program contract. Sky Warden, an aircraft
being developed for the Armed Overwatch program by
L3Harris will become the first forward-fit deployable combat aircraft
to feature Garmin's G3000 tandem integrated flight deck,
according to Garmin.
The G3000 provides USSOCOM with the latest communication,
navigation, surveillance air traffic management (CNS/
ATM) capabilities with commercial-off-the-shelf (COTS) solutions
based on Garmin's modern open system architecture
design. L3Harris has integrated its mission management system
along with a wide range of military sensors, communications
equipment, and weapons systems into the G3000 touch
screen human machine interface (HMI).
One major goal for L3Harris is leveraging the integrated flight
deck's ability to enable rapid deployment of new technologies.
Garmin's user interface for the G3000 is completely software-based,
so it's easily configurable for specific airframes and avionics configurations.
Future enhancements, applications and system
growth capabilities can all be achieved with software updates that
do not involve physically altering the mechanical controls.
The night vision goggle compatible G3000 contains synthetic
vision technology (SVT) that creates an outside the

" We wanted to reduce the weight of the part by 25 percent but
also improve the pressure losses of the secondary air flow as well
as a strong reduction in part count to improve maintenance, " said
Dr. Günter Wilfert, GE AAT Munich's Technology and Operations
Manager. " Those targets were achieved and surpassed. We were
able to reduce the weight by 30 percent in the end. The team also
reduced the manufacturing lead time from nine months to two
and a half months, by approximately 75 percent. Over 150 separate
parts that make up a conventional turbine center frame
casing have been consolidated into one single-piece design. "
The turbine center frame, an inherent component of modern,
turbofan aircraft engines, serves as a duct for the hot gas that
flows from the high-pressure turbine into the low-pressure turbine.
Conventionally, they are manufactured by casting and/or
forging, followed by additional machining steps.
This new additive manufacturing design solution on engine
frames is not limited to turbine center frames for future
engines; it can be leveraged to existing and legacy engine center
frames. The proposed design features can also be transferred
and/or scaled to turbine rear frames (TRF), low pressure
turbine casings and turbine mid frames (TMF).

Sky Warden is also equipped with Garmin's GFC 700 digital
autopilot which augments to the flight management system's
(FMS) ability to generate complex, pilot configurable search
and rescue (SAR) patterns.
Additional features within the G3000 integrated flight deck on
the Sky Warden include terrain awareness and warning system
(TAWS), traffic collision avoidance system (TCAS), and automatic
dependent surveillance-broadcast (ADS-B IN) traffic.
The Armed Overwatch program includes delivery of up to
75 fixed-wing aircraft.
