Large Project Fall 2006 – Spring 2007

ELM4701/ELM4702 - ELM Project I & II

Wind Instrument Testing Apparatus Project - WITAP

 

Product Name: Wind Instrument Testing Apparatus - WITA

Team Members: Robert Koch and Andrew Lawrence

 

Background: An anemometer is a device used to measure wind speed.  Commonly it is mounted on towers and high places.  The data generated from these devices is used to assess the feasibility of wind power generation at that site.  The accuracy of this data is important for the proper assessment of how a wind turbine would function at the site.  The functioning of the anemometer is important due to the difficulty of replacing a poor functioning device on a tower or at a remote site.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 The Problem: Vermont Technical College has an Anemometer Loan Program using NRG anemometers.  The anemometers need to be checked regularly for function and calibration.  NRG sends their instruments out to be calibrated.  A workshop device for calibrating anemometers needs to be developed with an effective range of air flow to assess anemometer operation and accuracy.

 Our Solution:  Build a machine that can output a steady air flow velocity that is effective and accurate enough to test for calibration a cup type anemometer.

Brainstorming/Sketches

Research/Feasibility Testing: A soft model of the chamber and fan was built and tested to determine air flow characteristics.
