IDI Technology - Aerodynamics
Modern aircraft and automobile designers rely more and more on aerodynamics
and wind tunnel testing to produce high speed, energy efficient streamlined
designs for today's modern vehicles. Large structures such as ships, tankers,
bridges and towers now require significant aerodynamic design to function
properly under high winds and inclement weather conditions. NASCAR racing,
sailboat racing, and even bicycle racing rely on superior performance
from sophisticated aerodynamic design and flow sensor measurements. While
these high performance designs are typically refined in wind tunnel tunnel
testing, IDI has developed a new line of aerodynamic sensors that make
"on the track" and field measurements a viable substitution. The basic
concept of this technology is the detection of boundary layer induced
pressure and shear fluctuations using a high frequency response surface-mount
piezoelectric transducer array. When mounted on the vehicle, flow field
lines are plotted directly from the sensor signal, excited by the airflow
as the vehicle is moving. Flow patterns can therefore be deduced right
from the vehicle on the track, in a variety of real world conditions.
IDI seeks to work with interested parties to apply these sensor technologies
or related product areas and is available to provide engineering services,
license technology, or in some cases provide complete sale or technology
transfer. The following abstracts describe a summary of currently available
IDI technologies for aerodynamic testing applications.
