SUMMARY

The discussion centers on calculating the Mean Aerodynamic Chord (MAC) for a wing, specifically focusing on determining the necessary distance from a diagram. Participants emphasize the importance of geometry in this calculation, suggesting methods to locate the centroid of each wing section. The conversation highlights that while the values in the example are not real, geometric principles can be applied to derive the required distances. A specific method involving vertical lines to assist in finding the MAC is recommended.

PREREQUISITES
  • Understanding of Mean Aerodynamic Chord (MAC)
  • Basic geometry principles
  • Familiarity with wing design and aerodynamics
  • Ability to interpret technical diagrams
NEXT STEPS
  • Research geometric methods for calculating Mean Aerodynamic Chord (MAC)
  • Learn how to locate centroids in wing design
  • Explore technical resources on wing aerodynamics
  • Review examples of MAC calculations in aeronautical engineering
USEFUL FOR

Aeronautical engineers, students studying fluid dynamics, and professionals involved in aircraft design will benefit from this discussion.

TL;DR
Hi!

I´m going to calculate the Mean Aerodynamics Chord MAC but I need the distance of the line in red

How can I calculate?

Please!

Welcome to PhysicsForums. :smile:

Is that wing from a particular aircraft? If so, you can probably find the dimensions online somewhere.

Is this question for schoolwork? If so what is the full problem statement. If not, what is the application?

no,I should find this distance
The values aren´t real. Geometry should be used
This is a example for a wing.But,I need that distance to solve the MAC

There are quite a few red lines in that diagram.
Are you referring to the one labelled cuerda de raiz fisica?
Alternately, is it possible you need to find the length of the line in blue?

There is not enough information to find the length of the "cuerda de raiz fisica" line, but there is enough information to find the length of the blue line. Drawing a vertical line down from its left end can help.

Welcome, Melissa! :smile:
There is a geometric method that you could use, first locating the centroid of each section of the half-wing, where the MAC of each section is located at, then finding the MAC that is equivalent for the whole half-wing.

Please, see this example:

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
