The Ate AEROTECH Ltd (ATE) Integrated Balance and Wind Tunnel Model Motion System is a compact unit which is designed to be installed within the cockpit area of the model. Specifically designed actuation systems are assembled around the latest generation of Internal Strain Gauged Balance to provide a system that measures the aerodynamic load, as six separate components, and can also move the model in roll, pitch and yaw, rotation about the X, Y and Z axes respectively.
Technical Summary
The Balance load ranges and Model Motion criteria are considered and determined during the design phase in conjunction with the user=s space envelope. Typical values of a system suitable for a 50% model are shown below for guidance only.
| Balance Component | Load Range |
|---|---|
| Fx Drag | 600 N |
| Fy Side Force | ±500N |
| Fz Down Force | 3000N |
| Mx Roll Moment | ±150Nm |
| My Pitch Moment | ±600Nm |
| Mz Yaw Moment | ±250Nm |
| Motion Axis | Motion Range | Rated Speed | |
|---|---|---|---|
| Ax Roll | ±3° in minimum steps of 00.01° | 0.5°/sec | The above figures are typical only as each system is designed and manufactured to customer specific requirements. Different load ranges can usually be accommodated. System size: 410mm long x 190mm wide x 230mm high System weight: 70kg |
| Ay Pitch | ±2° in minimum steps of 0.001° | 0.2°/sec | |
| Az Yaw | ±10° in minimum steps of 0.01° | 0.4°/sec |
