Scale Model Quantitative Flow Visualization of a Pterosaur

This paper studies the aerodynamics of a pterosaur. The pterosaur is believed to be the earliest vertebrate to have achieved powered flight, but much is unknown about specific flight behavior and performance. These studies will improve the understanding of animal aerodynamics and flight characteristics, which can then be used for scale model flight vehicles. Using a scale model of a pterosaur, the surrounding air flow is studied using a WindShaper and PIV (Particle Imagery Velocimetry). The WindShape's technology is based on the concept of an open circuit wind tunnel using an array of individually controlled fans. This allows for the model to be subjected to realistic weather conditions, such as wind gusts and shear. The flow around the pterosaur is studied in a much more realistic flying environment, with chord based Re of around 150,000.
