Need help with this lift-line theory application

Click For Summary
SUMMARY

The discussion centers on the application of lift-line theory in aerodynamics, specifically regarding the Angle of Attack (AOA) and its impact on lift coefficient (CL). It is established that the AOA should enhance CL until a critical AOA is reached, beyond which the lift does not increase further. The critical angle is determined through experimental methods specific to each wing design.

PREREQUISITES
  • Understanding of lift-line theory in aerodynamics
  • Familiarity with the concept of Angle of Attack (AOA)
  • Knowledge of lift coefficient (CL) and its significance
  • Experience with experimental methods in aerodynamics
NEXT STEPS
  • Research the relationship between AOA and CL in various wing designs
  • Study experimental techniques for determining critical AOA
  • Explore advanced aerodynamic concepts related to lift-line theory
  • Investigate the effects of wing shape on lift performance
USEFUL FOR

Aerodynamics students, aerospace engineers, and aviation professionals interested in optimizing wing performance and understanding lift dynamics.

TL;DR
I'm calculating the lift coefficient of an elliptical wing while i'm changing the values of AoA. Then, i'm doing an CL vs AoA plot, but here it shows a straight line and i read that it's supposed to stall in one point, but it's not happening here. What can I do? Or how can i interpret this result?

Welcome, angel1601! :smile:

The AOA should increase the value of CL, but only until the critical AOA (maximum value is reached).
The critical angle is normally found for a specific wing via experimentation.

Please, see:
