Understanding Lift & Wings: Upscaling Data for Real Planes

Click For Summary
SUMMARY

This discussion focuses on the relationship between the angle of attack, wingspan, airspeed, and lift force in the context of real aircraft wings. The Reynolds number is identified as a critical factor in understanding lift but is not clearly linked to the lift produced by wings in the conversation. Key concepts discussed include Bernoulli's law, which explains the aerodynamic principles that prevent wings from falling. The conversation highlights the need for further exploration of how these factors interact in real-world applications.

PREREQUISITES
  • Understanding of Bernoulli's principle
  • Familiarity with the concept of the Reynolds number
  • Basic knowledge of aerodynamics
  • Experience with measuring lift forces
NEXT STEPS
  • Research the relationship between Reynolds number and lift in aerodynamics
  • Explore advanced topics in fluid dynamics related to wing design
  • Study the effects of angle of attack on lift generation
  • Examine real-world applications of lift calculations in aviation
USEFUL FOR

Aerodynamics students, aviation engineers, and anyone interested in the principles of lift and wing design in aircraft.

Hi guys,

I'm working on a project for school and I have measured the influence of the angle of attack, the wingspan and the speed of the air on the lift force the wing is producing. Now I have the question what these data say about real wings from planes. I've already red it has something to do with the Reynolds number, but I can't link the Reynolds number on the lift the wing produces.

Welcome to the PF.

What reading have you been doing about wings so far?
 
I've red about Bernoulli's law and I understand why wings don't fall out of the sky. I know the Reynold's number is defined as the ratio of inertial forces to viscous forces.
