Linear, Annular, and Sector Cascade Testing

Techsburg offers linear, annular, and sector cascade testing using their in-house test facilities. Typical applications include aero and heat transfer measurements of compressor and turbine blade rows for both aero and power generating engines. Advanced diagnostics are available to provide detailed flow analysis. Techsburg specializes in custom rig designs for one-of-a-kind testing needs. Brief descriptions of the specific capabilities of each of the cascade rigs are provided below

Linear Cascades

• 120 degree range of incidence angle variation
• Independent control of Mach and Reynolds numbers
• Reynolds numbers range of 50,000 to 2,000,000
• Subsonic and supersonic exit flow
• 1 – 6% turbulence intensity

Annular Cascades

• Custom inlet flow profiles
• Secondary air supply for cooling flow
• Mass flow measurements
• Independent control of Mach and Reynolds numbers
• Reynolds numbers range of 500,000 to 3,500,000
• Subsonic and supersonic exit flow
• 1 – 6% turbulence intensity

Sector Cascades

• Warm inlet flow and chilled cooling flow for heat transfer applications
