Office hours: By appointment

• Lab Groups will be assigned.
• Your Lab group time will be selected on the Friday before the week the laboratory is scheduled.
• Read the Laboratory Handout before coming to the Lab.
• All Experiments will be performed in tunnels at the Hessert Lab.

• A wind tunnel is a device that can be used to test aerospace vehicles or their components under controlled conditions.
From Wind
Tunnel Testing by
Pope

• Wind tunnels are used to obtain aerodynamic information on aircraft bridges, buildings, automobiles and various other objects.
• Wind tunnels have been designed for a wide range of flight speeds.
• What type of information can we gain from a wind tunnel test and why is it important?

• Wind tunnels help designers to build confidence in their design.
• Experiments provide information so that the designer and corporate leaders can confidently commit to a major new development program.

• Design time for a new transport aircraft is approximately 4.5 years.
• The Company must pay thousands of engineers and support people to design and develop the airplane.
• For example, Airbus has probably had to mortgage the net worth of the company to finance the development of the A380.
• If the A380 is not successful the Airbus would be in big trouble financially.

• Gross weight 1.2 million pounds
• 555 to 840 passengers
• Maximum range
10,000 miles
• 20% more efficient than B747-400

• To understand how experimental techniques can be used to provide improved understanding of aerodynamic phenomena.
• To appreciate ethical issues dealing with experimental studies.
• To be able to critical assess experimental information.
• To be able to present your results in a well written technical report.
• To be able to present a good oral presentation of your work.
• To be able to work effectively as a member of the team.
• To be able to design an experiment.

• Course Schedule
• Course Policy
• Report Format
• Peer Review report
• Laboratory handout
• Supplemental material

• You must attend your assigned laboratory session.
Failure to do so will result in a zero for that laboratory exercise.
• Laboratory reports must be turned in on time. Late reports will be penalized.
• For the individual lab report you will collect the data as a group but you must not collaborated with anyone in analyzing the data or in writing up your report. Failure to do so will be an honor code violation.
• For group laboratory reports you should work as a team to collect, analyze, interpret and document your results in a clearly written technical report.

• Four group lab reports* @ 10% each
• One individual lab report
• One group oral presentation
