Aircraft wing spoiler

Anonymous — Fri, 24 Jul 2020 15:47:33 GMT

Hi all, I am a self-learner of Fusion 360. I am working on designing a spoiler on an aircraft wing. I did not know where to start. Watched a lot of videos but I didn't find anything that was helpful for me. So, I've decided to post a forum seeking for some help.

I am trying to add a spoiler to this wing(file attached) so that I can do its simulation later. I am also attaching two screenshots on how a spoiler looks. The dimensions of the spoiler doesn't really matter here, as I need to keep changing the dimensions according to the results. I would just like to know how to actually build a spoiler on an aircraft wing with any dimensions.

Since my skills in Fusion 360 are limited, it would be very helpful if you share a screen cast on how to do this. Thank you in advance.

New Component, Activate it,

Surface > Create Offset, Select Top face of the wing. Hide the solid wing.

Sketch in Top View, Project the wing skin outline, Draw the top view of the Spoiler.

Go to Solid area, select larger sketch profile, Extrude Cut the skin to leave you just the spoiler.

Thicken the Spoiler, To the inside, Unhide the solid wing.

Combine Cut the spoiler body out of the solid wing solid body, Keep Tools.

Joint the Spoiler to the wing, As Built Revolve, Set Joint limits.

Enjoy....

"I would just like to know how to actually build a spoiler on an aircraft wing with any dimensions."

I'm not sure of your application here, but the dimensions of the spoiler would need to be relatively small compared to the drawings you are referencing. Of the aircraft I know with that NACA airfoil I don't think I know of one that has spoilers/speed brakes. Might want to reference the dimensions/style of speed brakes used on Mooney M20 aircraft (different airfoil entirely though) instead to assist in boundary layer separation.

The example file could hardly be regarded as a representation of a wing in real world.

I take it that the Op needs instruction for Fusion tools.

Hi Dave,

Thank you for your response. I really appreciate that you took time and tried to explain how to do it.

Could it be possible for you to share a screen cast of the process you explained? I think I am missing something while doing this. I am unable to do it.

Thank you.

Sorry I didn't see the file attached the other day,

https://autode.sk/305avs2 (might take a while to process)

Your file modified, based on what I found in it, slightly different approach this time, add your own dimensions.

Might help....

Sorry I took so long to figure out how to implement working joint limits. Can't just do a Revolve, because there isn't a good planer edge to work with that will properly set the appropriate rotation direction.

But otherwise, this kinda replicates the steps listed previously.

Thank you very much for your response. It was a very detailed video. I've learnt a lot. I really appreciate it.
