Model Positioning Systems
Features and Benefits
The model position system supports the model weight and the aerodynamic loads generated by model aircraft with the least possible flow interference. During most of our history, we were collocated with the San Diego Low-Speed Wind Tunnel. That experience, along with providing test support in many facilities across the US, gave us invaluable experience in wind tunnel operations. Lessons learned over decades of testing are incorporated, resulting in robust, user-friendly systems that increase wind tunnel productivity. We provide full design, software, and control system development, fabrication, assembly, calibration, and on-site installation to meet your testing requirements.
The Crescent Support System provides pitch and yaw angle variation for typical sting-mounted models. The pitch and yaw centers of rotation are on the center line of the tunnel and do not translate; the pitch center does not move as the angle is changed. Any position combination of Pitch and Yaw is achievable at any time.
Scalable Design
Calspan's scalable Model Positioning Systems easily integrate into new and existing facilities with minimal impact on tunnel operators. The Integrated Motion Control and Data Acquisition System provides real-time load calculations.
Dependability
Pitch and yaw centers of rotation are on the center line of the tunnel and accurately maintain that location even when the angle is changed. Each axis may be set to a constant position while the other is varied.
Easy Operation
Our model position systems have repeatable interfaces that result in excellent performance and ease of use.
