High Speed Wind Tunnels
WE OFFER:
- Weight and pressure measurement of 2D airfoils and 3 D scale models (mock-ups of airplanes, their parts, half-wings, missiles and other bodies that are exposed to high velocity effects in operation)
- Non-steady pressure measurement on these mock-ups
- Probe calibration (static pressure and total pressure probes, directional sensors, ice-accretion probes, etc.)
- Pressure characteristics of new probes being developed at various angles of attack
- Flow visualization
EQUIPMENT:
An atmospheric intermittent suck-down wind tunnel (A):
- Tunnel designed to measure scale models´ aerodynamic characteristics
- It features a device to excite vibrations in model tested
- Four working sections can be made up:
| TUNNEL | A1 | A2 | A3 | A4 |
| Working section (m) | 0,9 x 0,6 | 0,6 x 0,6 | 0,6 x 0,6 | 0,4 x 0,8 |
| Mach number | 0,2 - 0,75 | 0,3 - 1,1 | 1,4 - 2,1 | 0,15 - 0,9 |
| Head (MPa) | 0,1 | 0,1 | 0,1 | 0,1 |
| Re # (SAT) | 2.106 | 2.106 | 2.106 | 3.106 |
| Time of run (s) | 8 | 8 | 6 | 10 |
| Angle of attack (deg) | -12+12 | -12+12 | -12+12 | -18+20 |
| Walls of test section | closed | erforated | closed | slotted |
| Wall opening (%) | 22,5 | 0 - 10 |
A calibration atmospheric aerodynamic intermittent-run wind tunnel (C)
- Tunnel is designed for small diameter probe calibration and tests
- Working section is 0.12 x 0.12 m
- Manipulable Mach numbers up to M 1.1
- Tunnel is fitted out with device to excite flow air vibration to change inlet pressures for non-steady pressure measurement
- Virtually uninterrupted run type due to a small size of working section
An atmospheric intermittent wind tunnel (M):
- Tunnel is designed to measure aerodynamic characteristics of scale models of small size and to calibrate pressure pick-ups
- Mach number range 0.2 – 2.1
- Working section size 0.24 x 0.2 m
- Perforated walls
CUSTOMERS:
- Aircraft manufacturers
- Aviation industry suppliers
- Customers using pressure pick-ups
- National and international research and development projects
