Key points

  • The report details the design and fabrication of forward-swept counterrotation blade configurations for wind tunnel testing under NASA Contract NAS3-25269.
  • The primary focus was on evaluating the aerodynamic, aeromechanical, and acoustic performance of counter-rotating blade concepts.
  • Feasibility studies compared forward-swept and aft-swept blade designs to assess their impact on rotor interaction.
  • The report includes analyses and fabrication procedures for multiple blade sets, including a third set with enhanced stiffness based on earlier test results.
  • Scale-model propulsor testing was conducted at NASA Lewis Research Center, although results from this testing are not included in the report.
Frequently asked questions
What was the main objective of the report?

The main objective was to theoretically and experimentally investigate unique counterrotating blade concepts, focusing on their aerodynamic, acoustic, and aeromechanical performance.

What types of blade designs were evaluated in the study?

The study evaluated both forward-swept and aft-swept blade designs to understand their effects on rotor interaction.

What was the significance of the third blade set mentioned in the report?

The third blade set was produced with a stiffer outer ply material to achieve the design point operating line that previous blade sets had not reached.

Where was the scale-model propulsor testing conducted?

The scale-model propulsor testing was performed at NASA Lewis Research Center in Cleveland, Ohio.

Are the results of the scale-model testing included in the report?

No, the test results and comparisons to analytical predictions from the scale-model testing are not presented in this report.
