OEA AWARD CRITERIA

� Demonstrates engineering challenges and

innovative solutions

� Integrate a Blower, Motor and VFD that will

perform as required under harsh conditions

with no mistakes, thereby enabling

Honeywell to maintain its commitments.

� Modify commercially available equipment to

meet the operational requirements of the

wind tunnel.

24

OEA AWARD CRITERIA

� Demonstrates the importance of the

engineering profession to society

� The wind tunnel will be used for

performance and endurance testing of

equipment enhancing the safety of large

commercial and military aircraft.

� The wind tunnel would not exist without the

blower, motor, VFD and PLC System which

are engineered products and systems.

25

OEA AWARD CRITERIA

� Demonstrate a clear and tangible benefit to

the Delaware Valley Region 2.

� Local engineering and design talent

enabled us to perform this project without

no issues, within schedule and within

budget.

� Awaiting future turnkey projects to design

and build the power and control systems for

many more 2,000 to 3,000 HP Wind

Tunnels in the next five year.
