Sphere

About Sphere

Overview

A precision sphere model designed for transonic and supersonic wind tunnel testing, ideal for baseline drag studies, flow symmetry validation, and calibration applications. Available in multiple diameters to match test section size, the sphere provides repeatable and well-characterized aerodynamic behavior.

Key Features

• Simple Geometry: Ideal for baseline and validation studies
• Multiple Sizes: Scaled to suit various test sections
• Optional Pressure Instrumentation: Configurable tap locations
• Sting Mounted: Threaded base for quick installation
• High-Precision Manufacturing
