3 Customers Dr. Siva S. Krishnan, Professor Manish K. Saini, Research Assistant

4 Laser Extinction Device Laser Horizontal Knob Vertical Knob Burner

5 Planning the Project – Gantt Chart

6 Customer Requirements & Project Objectives Align the Laser to the Burner Improve Safety Improve Accuracy More Ergonomic Cost Effective Decrease Experiment Time

7 Problems with Benchmark

8 Concept Development & Design 1. Design Concepts  Motorized Vertical & Horizontal Travel  Motorized Vertical Travel with Manual Horizontal Travel  Manual Extension on Vertical Travel 2. Alignment Procedure

9 Concept #1 

10 Concept #2 

11 Concept #3

12 Alignment Procedure Alignment Target  Normalize the laser to the burner surface  Put the goggles on to view laser beam  Use the LabView program to move the burner until the laser is aligned on the target  Move the burner in the positive vertical direction 76.2 millimeters.  Open COSMOS program provided by Velmex and set the zero position Zero Position

13 Final Design Concept Cost MANUAL TO MOTORIZED CONVERSION KIT MMC $95.00 MANUAL TO MOTORIZED CONVERSION KIT MMC $95.00 VEXTA PK266-03A STEP MOTOR $ VEXTA PK266-03B STEP MOTOR $ D6CL DAMPER FOR TYPE 23 STEPPER MOTORS $88.00 VXM-2 PROGRAMMABLE STEP MTR CNTRL,2 AXIS $ Total Cost$1,383

14 Design Validation BenefitsPer Experiment Fuel Savings $25 - $50 Oxygen O 2 Savings $50 - $75 Improved Time 45 min – 1hr Improved AccuracyFrom ± 0.1 mm *********************************************************** More Ergonomic Enhanced Safety Cost Effective
