Background - AAT

Advanced Atomization Technologies (AAT)• Joint venture between General Electric Aviation and

Parker Aerospace• Formed in 2012• Specializes in manufacturing and testing fuel nozzles for

gas turbine engines

Background - Project

Fuel Injection Nozzle Testing System• Qualifying fuel injection nozzles• Specialized calibration equipment• Expensive, odorous calibration fluidProblems with system• Offensive odor permeates entire building• Loss of expensive calibration fluid

Problem Definition• All commercial aircraft nozzles must undergo a flow test to

assure that requirements are met for spray angle.• This test uses Stoddart Solvent (MIL-PRF-7024F Type II)• Petroleum derived, clear, transparent liquid.• The fluid is very expensive and has an offensive odor• The current exhaust system is ineffective at both containing

containing the odor and recovering the atomized fluid for reuse.

Fuel Nozzle Test Chamber

MSDS“Inhalation:

Breathing of vapor or mist is possible. Breathing small amounts of

this material during normal handling is not likely to cause harmful effects.

Breathing large amounts may be harmful.”

“Symptoms:

Signs and symptoms of exposure to this material through breathing, swallowing,

and/or passage of the material through the skin may include:, stomach or

intestinal upset (nausea, vomiting, diarrhea), irritation (nose, throat, airways),

central nervous system depression (dizziness, drowsiness, weakness, fatigue,

nausea, headache, unconsciousness) and other central nervous system

effects, and death.”

Use Scenario

Additional Scenarios• Angle test - purge atomized fluid, remove

nozzle• Flow test, connection failure - purge atomized

fluid, reconnect nozzle, repeat test• Angle test, connection failure - purge atomized

fluid, reconnect nozzle, repeat test

Benchmark Parameters • Air Quality (PPM)• Overall cycle time (Min)• Setup time for system/nozzle so testing can begin (Min)• Volume of collected fluid (fl. oz)• Function of door lock mechanisms (no opening during

test)• Visibility in chamber during test• Maintain proper spray angles

Project Deliverables• Fully operational system for the GE90 nozzle

• Documentation package for application to additional chambers

Constraints and Challenges

• Cannot impact flow testing

• Flow test materials and test procedures may not change

• Should be able to fully contain the calibration fluid

• Must be adaptable to current test chambers

• Must meet all applicable wire & safety codes and specifications

• Must be within budget (Also, no one item can be >$5,000)

• Must fit within current footprint

• Must not add too much additional process time

Stakeholders• AAT (Jim Kalinski, David DeWispelaere)• GE Aviation• Parker Aerospace• Floor Operator• Financial team• MSD team• Gary Werth

Communication Plan• Contact with AAT is ongoing• Will be contacting them primarily with questions or

concerns• Will be providing updates on project status only as

needed• Points of contact for general project questions as well as

purchasing questions.
