Found a batch of military and aviation service pins and the two shown were in the group.

Does anyone recognize them or are they even military/aviation related?

One of them looks like an airfoil with the air flow over the wing but that is only a guess.

Any assistance is appreciated.

The GD is probably General Dynamics.

You are correct on the General Dynamics pin.  
Thank you.

Now for the other pin.  I did find out the person who owned this pin was a USAF pilot who was also an engineer.

I think you are correct that the other pin is depicting a side view of an airfoil.  It's possible that is also General Dynamics, but it could be other companies as well.  NASA also tests airfoils looking for the ideal design.

Found the id of the "Airfoil" wing:  Institute of the Aeronautical Sciences which was formed in 1932.
