What airfoil is used on the MQ-1B Predator's wing? There are lot of UAV's in todays world to be re worked on. The General Atomics series of UCAVs is quite remarkable. I have selected MQ-1B Predator UAV, for an geometric analysis project(undergraduate).
Though the wing dimensions including root and tip chord's length are found at https://mq-1predator.weebly.com/design-and-specifications.html and the rest performance specifications for it is available at https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104469/mq-1b-predator/.
Still it isn't mentioned anywhere at websites and in factsheet too, about its &quot;Airfoil profile&quot;.
I have been trying to figure it out.
Can anyone please help me out to ascertain MQ-1B's airfoil profile?
The MQ-1B uses three different airfoils: Drela GW-19, GW-25 and GW-27, created by Dr. Mark Drela (one of the creators of the XFOIL software) and proprietary to General Atomics.

The airfoils used on the MQ-1B (Drela GW-19, GW-25, GW-27, created by Dr. Mark Drela) are proprietary material of General Atomics. Dr. Drela personally stated on a hobbyist remote-control drone forum that a scale model should use an SD7032 wing (similar shape to a NACA 3510), while the full-scale MQ-1B airfoils &quot;...have LOTS of top surface camber.&quot;
