F1 Subsonic Wind Tunnel, Pressurized, High Reynolds number, High efficiency

MAIN FEATURES

 

Subsonic continuous pressurized wind tunnel, variable pressure from 1 to 3.85 bars, Mach number: from 0.05 to 0.36. A large, high Reynolds number, low speed wind tunnel with high productivity.

Wind tunnel designed for high productivity and test confidentiality.
Rectangular test section:

  • length: 11 m
  • width: 4.5 m
  • height: 3.5 m

 

The test section is movable and can be fitted with any of the pallets forming the test section floor.
Each pallet includes the model support and a data acquisition unit. This arrangement enables a full preparation of the test in separate cells.

 

 

 

Four pallets are available: pallet #1 is equipped with a sting holder quadrant, the three other pallets are multipurpose and adaptable to any kind of support.
The F1 powerplant is a 16-blade constants-speed fan driven by a 9.5 MW electric motor. Mach number is adjusted by changing the pitch angle of the blades.

TYPICAL TESTS

  • The wind tunnel is well adapted to high-lift configuration studies.
  • Aerodynamic force and moment (6 components) measurements on complet or half-models.
  • Control surface force measurements.
  • Large models of transport aircraft (more than 3 m span) or military aircraft.
  • Tests with engine simulation (turbofan or turboprop).
  • Ground effect tests.
  • Air intake tests for fighter or transport aircraft (steady and unsteady measurements).
  • Two-dimensional airfoil tests.
  • Special tests:
    • dynamic stability measurements,
    • building, ship, car, helicopter tests.
  • A larger scope of activities for customers worldwide.

Measurement techniques

Model deformation measurments (MDM) over the entire operating envelope of F1, up to 3.85 bar stagnation pressure

Particle Image Velocimetry (PIV) over the entire operating envelope of F1, up to 3.85 bar stagnation pressure

Pressure Sensitive Paint (PSP) over the entire operating envelope of F1, up to 3.85 bar stagnation pressure

CONFIDENTIALITY

 

 

  • Test preparation in isolated and protected premises (checked access control and video-surveillance).

 

  • Confidentiality of test and data guaranteed, even in case of simultaneous tests for different customers.
