4/6/2007 - EDWARDS AIR FORCE BASE, CA. -- The 412th Test Management
Group completed the range acceptance certification procedure
on March 23 for the newest range mission control room built
to test the F-35 Joint Strike Fighter.
Unofficial assessments of the certification state the control
room is ready to support any mission, said Michelle Caldera,
program manager of the Range Control Rooms project with the
412th Test Support Squadron project management directorate.
"It's exciting to work on something this significant
and state of the art," said Ms. Caldera. "We're still
working on getting the security certification completed."
The range control room was designed to provide the F-35 test
team with the facilities necessary to monitor the real-time
performance of the aircraft during its test missions here, said
Steve Cronk, Director of Operations for the 412th Range Squadron.
The construction of the control room started in 2004, and took
about six months to complete. Equipment installation and room
certification is now completed, and the room is scheduled to
be commissioned Wednesday. The 412th Range Squadron, a part
of the 412th Test Engineering Group, is responsible for the
operation and maintenance of the JSF control room.
"The new control room is actually just one of the many
control rooms that the range squadron uses here in the Ridley
Control Center," said Nancy Bergren, test support operations
lead with the F-35 Integrated Test Force. "Initially, we
looked at the range's existing control rooms and determined
there wasn't enough capacity to support the JSF."
Up to approximately 40 flight test engineers from the F-35
Integrated Test Force will work in the control room, Ms. Bergren
said. Eight people on the range support the operations and maintenance
of the control room.
The tests are conducted by the Integrated Test Force, which
is comprised of government civilian, military, contractor and
foreign partner personnel, Mr. Cronk said.
"The control room allows us to deliver a better product
to the warfighter sooner," he said. "The capability
here provides us the ability to thoroughly test and evaluate
the performance of the F-35 and find any problems with the aircraft
long before we deliver it."
During missions, the control room will receive telemetry data
from the F-35 and video data from the range, Ms. Bergren said.
"The technology in this control room is state of the
art in real-time data-processing capabilities," Mr. Cronk
said. "When the JSF is full up and running, this control
room will process about 250,000 parameters from the aircraft
at 3 million samples per second. The F-22 had 120,000 parameters
processed at about 1 million samples per second. So you can
see how technology has improved in just a few years."
"We know everything that is happening on the aircraft,"
Mr. Cronk said. "In the 250,000 measurements received from
the aircraft, we can see stick positions, rudder positions,
internal engine temperature, brake pressures and more. You name
it, we see it all in the mission control room in real time.
It is far more information than the pilot could ever possibly
know while flying the aircraft."
Once a mission is over, the flight test engineers can access
the data from their personal computers for a more detailed analysis,
Mr. Cronk said. The data is electronically transferred down
to the Integrated Test Force's facility here, where it is put
on a storage system.
"Because there is so much data coming from the aircraft
in flight, we could not possibly look at all of it in real time,"
Mr. Cronk said. "The engineers can go back and look at
specific aspects of the test and get a better feel for the aircraft.
In the future, the flight test team can compare data received
10 missions ago and compare it to present performance to see
the changes and improvements they have made."
The first aircraft is being tested in Fort Worth, Texas, and
is scheduled to arrive here in September for testing, Ms. Bergren
said. The second aircraft delivered from Lockheed will be a
short takeoff and vertical landing variant, which will go to
Patuxent River Naval Air Station, Md. The first conventional
takeoff and landing variant to represent Air Force specifications
is set to arrive here in 2009.
"The new control room is the first control room that will
be able to support the F-35," Ms. Bergren said. "We
plan to build three more control rooms, which will enable us
to conduct four F-35 test missions at the same time and receive
data from each one independently. Some of those missions will
have more than one F-35 in them."
The good flying weather, proximity to the lake beds and the
infrastructure of the test facilities make Edwards an ideal
place to test the F-35, Mr. Cronk said.
"Edwards is also close to other ranges in the Southwestern
United States," he said. "Some missions will fly over
Vandenberg Air Force Base, Calif., and over the ocean. We can
receive data from that location as if the aircraft were sitting
on the ramp here."
Edwards will have five F-35's permanently assigned here in
the future for developmental testing and up to three Naval variants
visiting, Ms. Bergren said.
"This is the best place to do 'engine-out' testing of
a single engine aircraft," she said. "Engine-out testing
involves shutting down the engine in flight to prove that the
aircraft can restart the engine in flight. If the engine does
not restart, the lake bed provides a suitable place to land
the aircraft."
The new control room is unique because it is entirely personal
computer based, Ms. Bergren said. It is the next generation
beyond the control rooms used for the F-22A Raptor. It is larger
and capable of processing more information per second.
Ms. Bergren said the control room has performed well in acceptance
test runs. During the tests, engineers in the control room received
information from a mission simulator. They ran through the information
cards and communicated with each other as if it were a real
mission.
"After the commissioning on Wednesday, we want to start
doing rehearsal missions as soon as possible," Ms. Bergren
said. "Rehearsals will be conducted using simulations and
data played back from Fort Worth F-35 testing. We expect the
aircraft to arrive in September for live aircraft test support
missions using the new mission control room."
The JSF system design and development phase is scheduled to
end in 2013, but further testing is likely beyond that, Ms.
Bergren said.
"Making the control room a reality for JSF has been challenging
and a lot of fun," she said. "I think we have created
an awesome control room that will be able to support the F-35
for the life of the program."
