About Pyramidal Balance

Overview

High-precision external pyramidal balances designed for accurate aerodynamic force and moment measurement in wind tunnel testing. Engineered for reliability and direct measurement output, these systems provide real-time lift, drag, and moment data without complex post-processing.

Available in three sizes (small, medium, and large) and configurable as 3-component or 6-component systems, these balances are ideal for educational, research, and industrial aerodynamic applications.

Key Features

Direct Measurement: Outputs Lift, Drag, Side Force, and Moments directly
3 or 6 Component Configurations Available
High-accuracy load cells for force and moment sensing
Robust Construction: Aluminium, carbon steel, and stainless steel
Modular Design: Compatible with various wind tunnel sizes
Manual or Motorized Pitch/Yaw Control

Measurement Capabilities

3-Component: Lift, Drag, Pitching Moment
6-Component:

Lift
Drag
Side Force
Pitching Moment
Yawing Moment
Rolling Moment
