Instrumentation
Force Measurements
Force and moment measurements (up to six components) are made using the external pyramidal type six - component balance built by the British company TEM .
The capacities of the balance are shown below:
- Lift: - 200 Kgf to +700 Kgf
- Drag: - 100 Kgf to +200 Kgf
- Side force: - 200 Kgf to +200 Kgf
- Pitching moment: - 110 Kgfm to +110 Kgfm
- Rolling moment: - 110 Kgfm to +110 Kgfm
- Yawing moment: -110 Kgfm to + 110 Kgfm
