Consultant to Sergeant Fletcher Incorporation - El Monte, California -

Senior Test Engineer

Small Diameter Bomb (SDB) Rack and Carriage System - Designed, developed,

integrated and maintained Carriage System Test Set (CSTS) and its test

cables (1760, Telemetry, MMSI) connected to UUT (SDB Carriage System). The

Boeing MUX-CSTS is powered by 115VAC 3 400 HZ, internal 28VDC and 270VDC

power supply, DMM, BITE, other electronic cards such as Digital and Analog

I/O, MUX, 1553 Bus, etc and integrated with Boeing Visual Basic Software

in accordance to DO-160 testing specification. The UUT SDB Carriage System

contains of Carriage Main Harness, four accumulator assemblies (two on each

side), one Telemetry Interface, one 1760 Interface, one Carriage System

Control Electronics (CSCE) and one Compressor Assembly. The Compressor

Assembly consists of a motor, a coalescer, a filter and a fan which powered

by 115VAC 3 400HZ and 28VDC power supply which applies from the facilities

power. This sub-system will enable and pressurize fully to 5104 psi and the

motor will be disabled with the fan kicks in to cool off the motor while

the coalescar will split out the pressure every 10 seconds. The time to

enable and disable the compressor system took 20 minutes. Next 10 minutes

to stabilize and hold the pressure and another 10 minutes to check and

measure the pressure drop rate of <11.6 psi/minute. The total time to

complete the pressurization system is approximately 40 minutes.

The SDB Carriage System will test in Environmental Stress Screening using

thermistors, pneumatic valves assembly, pressurized hydraulic pumps,

valves, gauges and plumbings to test at (ambient, cold (-30Fand -5F) and

hot (140F and 158F)) for 3 full cycles took 2.5 days to complete. If

sampling plan (ambient and one cold cycles) takes day to complete. Each

cycle of tests will run Function Checkout (FCO) and Pressure Checkout

(PCO). The ESS test procedure was written and sent to Boeing for approval.

Trained test technicians to run the MUX-CSTS test set connecting to the

four UUT. Next, the SDB Carriage System will go through Vibration Chamber

which vibrates at 3g on three (Lateral, Longitudinal and Horizontal) axis

with three accelerometers connected on each test. The setup and integration

with "CSTS and its test cables (MMSI, TM and 1760)" and "Vibration Start UP

Test" take 3 hours to complete. The vibration test will run only FCO test.

Then, the Carriage System has to setup at Acceptance Test Procedure (ATP)

Test Stand 7A which simulates the bomb ejections on four stations in the

order of 3, 1, 4 and 2. The Test Stand 7A contains of Pylon Mounting

Structure, Bomb Rack SK404582 connected on top of the SDB Carriage System,

Data Recording System, 4 simulated bombs and ejection systems. The Data

Recording System uses Lab View 7.2 includes TCPIP, Object Oriented

Programming and DAQ (PXI-7851R) to control and record data from the four

bombs' ejections. The data consists of EOSV (Position vs. Time, Velocity

vs. Time and Position vs. Velocity). The ATP test procedure was written and

followed by test technicians to run FCO test, Single Weapon Station

Ejection (with pressure) takes 20 minutes and 10 minutes to stabilize

pressure at 4988 psi (total time 30 minutes) to complete. Next, bombs 3, 1,

4 and 2 start with data recording and ejections on individual tests

respectively. Excel data, graphs and test reports were presented to Boeing

customers and internal QA for sell-off the SDB carriages.

- Designed, developed and integrated Main Wire Harness Test Fixtures and

Test Set Cables (MMSI, TM and 1760) Test Cables' Fixture using CATIA and

programmed 1500 Horizon software with Horizon testers to troubleshoot and

test any failed Carriage Main Harness and Test Cables on Continuity and Hi-

pot testing.

- Trained test technicians how to troubleshoot failed SDB Carriages and its

components, test set and its cables, software, the test equipments and

others in accordance to the Test Plans.

Pneumatic Bomb Ejection Rack (PBER) System - Designed, developed,

assembled, maintained the Lockheed-Martin PBER Rack which consists of FWD

end-housing Gas Feed and AFT end-housing Gas Feed. Between the gas feed the

valve assembly and conduits were installed. Inside the valve assembly,

there are two orifices and spring loaded plunger connected. PBER Interfaces

have four hooks; fill valve; manual release shaft; test connector and four

solenoids' assemblies. Also, use hydraulic pressure pumps, valves, gauges,

plumping carts. Also connect to N2 gas tanks to test the Pneumatic Bomb

Ejection Rack. The ATP was written to perform the FCO and PCO tests before

the PBER Rack was connected to the Pylon Mounted Structure beam and the

simulated 2000 lbs bomb loaded on the ATP Test Stand 7B.

QTP was written in accordance to DO-160 test specification to test the PBER

Ejection Rack at thermal ESS with nitrogen gas connected to pressurize up

to 5700 psi. Next, the PCO was performed at ambient, cold (-40F) and hot

(160F). Then, the two string pots connected to PBER to measure the EOSV

data. Two cameras were also placed near the Ejection pitch to monitor the

FWD and AFT hooks, motion of the released bomb and other test equipments.

The NI DAQ (PXI-7851R), Lab View software and another computer were used to

collect EOSV data and ejection of the bomb.

- The PBER Rack was setup and installed upside down into the Vibe Fixture

on the Vibration Table at three (Longitudinal, Lateral and Vertical) axis

respectively. The three accelerometers were connected to the test fixture

to record the vibe data at 40g. The vibe tests were tested how long the

PBER components can survive by reviewing the vibe data, FCO data and other

software data. After the three hours vibration was done, the FCO test was

run in accordance to the ATP to observe the PBER Rack can survive the vibe

testing.

If any components on the PBER racks failed on the hardware, software, UUT

and its components, string pots, potentiometers, test cables or test sets,

the Notice of Test Deviation or Anomaly (NTDA) was written by the test

technicians. Test Engineer (TE) will respond to NTDA and the approval of

Project Engineering (PE) and Quality Engineering (QE). QE will create a Non-

conforming Material Report (NCMR) Number and TE will write test plans to

troubleshoot the failure analysis and root cause. The test plan is reviewed

by PE and QE. Test technicians or TE will execute the test plan. The final

recommendation of the test plan is presented by TE to PE and QE for

approval to close-out the test plan and NCMR and NTDA on both SDB and PBER

Programs.
