Vibracon:A
contract has been awarded to NSWC/Philadelphia and shock test planning
has commenced. A minimum of two pumps and a compressor will be
barge-shock tested using Vibracon chocks as the leveling and hold-down
devices.
DDG Valve Actuators:NSWC/Philadelphia
has been awarded a contract to conduct at-sea test and evaluation.
They are currently interviewing vendors and factory representatives
have visited USS ARLEIGH BURKE (DDG-51) to look at the intended test
application.
Variable Speed Drive: Upon
award of contract to NAVSEA/Philadelphia, they will install VSDs on CVN-68 class ships for
operational testing.
Magnetic Couplings:NSWC/Philadelphia
has been awarded a contract to evaluate and test potential solutions
to the water level indicator problems on fleet units. The ISEA has
identified several alternatives and is in the process of obtaining
components for testing.
Scullery
Dishwashers I:
MTTC
continues to provide
technical assistance to NAVSEA Philadelphia by employing former General Electric Appliance
engineers to analyze the current problems and provide recommendations.
A
contract has been awarded to NAVSEA/Philadelphia and analysis of
potential solutions has commenced.
Scullery
Dishwashers II: This
project was approved in January 2002. NAVSEA has provided necessary
documentation. Upon award of contract to NAVSEA/Philadelphia,
engineering and test efforts will commence. Fleet ships, in three
homeports will be used to verify replacement parts in CY 02.
UNREP Phone/Distance Line:
The at-sea testing
of the hand-held laser rangefinder was conducted on USNS TIPPECANOE on
April 22-25, 2002. A final report was issued by MTTC on May 22. Based
on the findings and recommendations, NAVSEA has requested that MTTC
extend its efforts and conduct at-sea testing of a billboard display
that would be used on the replenishment ships. MTTC has agreed and
preliminary planning is underway. Laser Atlanta will modify the
rangefinders with an inclinometer that will permit the calculation of
horizontal range, given slant range. Laser Atlanta will also loan a
display to the Navy for further testing.
Distiller
Anti-Scale:The
prototype unit is ready for at-sea testing. Plans to install on a
west coast ship have been delayed because the USS CARL VINSON
(CVN-70) (Smart Ship) availability work package has been overloaded.
NSWC/Philadelphia is now looking at the next available ships – USS
JOHN C STENNIS (CVN-74) or USS THEODORE ROOSEVELT in Norfolk.
Vertical Package
Conveyors:NSWC/Philadelphia
has made great progress in the past quarter. The PLC, Light Curtain,
chain auto oiler and variable drive has been installed and programmed.
Testing at the land-based test site will begin soon. Installation of
the PLC has been accomplished on the USS HARRY S. TRUMAN (CVN-75) (3
conveyors) and is underway on the USS CARL VINSON (CVN-70). Design of
the light curtain for combatants has begun.
Composite
Connectors:The
Navy has received the MTTC–provided wiring harnesses with composite
connectors from LiteCom, Inc. After testing on Phalanx CIWS systems,
it has been decided not to adopt the concept for fleet-wide
application. While there is great potential that may later be
realized, the Navy engineers were not comfortable with the lack of
solid lock on the bayonet-style device. Further development is
anticipated.
CIWS
Acutator Cam Pin: Prototype
entrance unit and drawings have been provided to the Navy In-Service
Engineering Agent in Louisville, KY.In-house testing will commence when a test mount becomes
available.
Speedwrap
Insulation: During
the first week of May, BBNT, Inc. conducted a six-month evaluation on
the USS THEODORE ROOSEVELT (CVN-71). The sailors especially
appreciated the laundry application since it appeared to lower
temperatures by at least five degrees F. Flex hoses were noted as an
unexpected hand-and-glove application. A 12 month inspection will be
conducted in the late fall.
Laser
Induced Surface Improvement (LISI) of LCAC Lift Fan Blades: The contractors, ST2 and the University of Tennessee
encountered problems in adjusting the heat balance so the coating
would adhere without damaging (annealing) the Aluminum 6061 alloy
substrate. The contract expired without delivery of fan blades for
at-sea testing. This project has been terminated, however ST2 is
continuing work under other funding vehicles. A solution to the
problem may still be forthcoming.
Electrospark
Deposition (ESD) In-situ repair of hydraulic rams: Prior to utilization
on fleet asset diving plane rods, the ESD process must be formally
approved by NAVSEA. It is considered to be a SUBSAFE item. A draft
process instruction has been written and is in routing. Comments are
already being received. Given the critical nature of the equipment, a
quick response is anticipated.
Anti-Sweat
Paint: The
MTTC-sponsored testing at Naval Research Laboratory has been
completed. Based on these results the Navy has decided to conduct
additional testing onboard designated ships. This is ongoing and will
be completed in 2002.
