Technical Point of Contact (TPOC) or Contracting Officer’s Representative (COR)

Contract Line Item Number (CLIN) 0001 The Contractor shall provide one (1) Non-intrusive Stress Measurement System (NSMS), including all necessary hardware and software to meet the requirements listed below.

· Sixteen (16) channel high speed Data Acquisition System (DAQ) for NSMS measurements

· NSMS measurements shall be made on turbochargers for diesel engines in high temperature environments of up to nine hundred (900)°Celcius (C). Shaft speeds may reach two hundred fifty thousand (250,000) rotations per minute (rpm).

· The system shall be able to operate stably without a once per revolution signal, such as that from a turbocharger speed sensor. A system which operates unstably or unreliably in the absence of a once per revolution signal is not acceptable.

· The system shall process and display NSMS data in real time, including campbell diagrams, blade resonances, and blade deflection levels. Software that can only display such information through post-processing is not acceptable.

· The Government requires the ability to simultaneously measure blade deflections in a compressor wheel and a turbine wheel, each instrumented with eight (8) probes. The DAQ system shall be able to process and display the data for the two (2) wheels separately, and in real time.

· Operator interface computer with monitor, keyboard and mouse.

· Mobile cart to mount DAQ and computer.

· Sixteen (16) channels of laser detection modules, for connection to DAQ

· The system shall allow the operator to set the laser power level at which a blade triggers the detector independently for each blade. This is to allow a user to account for a turbocharger blade building up a layer of soot over time which changes its blades reflectivity to the laser. A fixed detection level is not acceptable.

· The modules shall include a safety interlock feature. This is a critical feature which the system will need in order to pass Government safety requirements. A system without an interlock is not acceptable.

· All necessary cables to connect laser detector to DAQ, each at least one hundred (100) feet long.

· Sixteen (16) channel air cooling system for probes in hot environments

· Twenty-Four (24) air-cooled optical probes with a tip diameter of 1/16” or less, each at least twenty-five (25) feet in length.

· Thirty-two (32) probe holders, ¼” in diameter or less, for mounting optical probes.

· The Contractor shall ensure the probes have the capability to be removed from one (1) turbocharger, and installed on a new one (1) without damaging the probe. The probes shall provide a good seal in a 2.5 bar pressure, 900 C° environment.

· Real-time NSMS analysis non-expiring software license, with one (1) year of maintenance for sixteen (16) channel high speed DAQ. Software that can only display high speed calculations through post-processing is not acceptable.

· Off-line NSMS analysis non-expiring software license with one (1) year of maintenance for the software package.

· The Contractor shall provide a one (1) year warranty on all hardware.

CLIN 0002

The Contractor shall provide an auxiliary data acquisition system for recording pressure, accelerometer, and temperature data from a Government-Owned turbocharger research facility.

· Sixteen (16) channel data acquisition module for type-K thermcouples, sampled at least Fifty (50) Hertz (Hz).

· Eight (8) channel data acquisition module for 0-10 VDC (volts of direct current) analog input, sampled at up to one hundred (100) kiloHertz (kHz).

· Eight (8) channel data acquisition module for 0-20 milliamp (mA) analog input, sampled at up to one hundred (100) kHz.

· User-interface non-expiring software license to allow users to view and record the above channels, with a time stamp for every time a data sample is taken.

· User-input gain and offset information for each of the channels in CLIN0002 o convert mA/VDC to real units such as kilopascals (kPa), gs of acceleration (g), degrees celcius (°C), etc..

· User-input channel names for all of the above channels.

· User-input recording speed for all of the above channels, at up to one hundred (100) kHz.

· Data output format will be in .txt files.

CLIN 0003

The Contractor shall provide onsite training for two (2) separate weeks by an engineer with expertise in the NSMS. The first week shall be for the initial start-up of the instrumentation and training on how to use it. The second week of training will take place once the Government has installed the systems from CLIN 0001 and 0002 in their turbocharger test facility, and is ready to exercise the full capability of the system. The Government plans to complete installation of this facility in the later half of 2018.

CLIN 0004

The Contractor shall provide remote technical support and consultation for NSMS analysis over the phone and internet for a period extending one (1) year from the delivery of hardware to the Government.
