I have a design for a VTOL plane and need to find plain airfoils to see if I can build a working model. I’m not picky about cross section but if I have a choice would probably try a version that maximizes lift such as one for a model glider.
I did a search on google shopping but couldn’t find anything.
this do?
How big we talkin?
There are several RC modeling forums out there. This is a random selection. I see information provided in responses all the time for questions like yours.
There are some simple KF airfoils made of foamthat can get you started quickly without investing a lot of time or money.
Thanks for the responses. Sorry it took me till now to see them in my subscribed threads list. I though it was odd that I hadn’t gotten any responses.
I’ve some motivational problems let’s say, so I’m very sporadic in what I can accomplish, but I’ve bookmarked all of the links and will refer back to them.
To simplify things to see if my idea is off the wall or legit, I’m thinking of building something that just consists of the airfoils and a source of thrust and the secret sauce which may or may not turn out to be bogus.
I just something big enough to lift all of the components. I would guess that something in the range of a medium to large RC airfoil will do the trick but as you can see I haven’t gotten into doing any calculations yet.
My first job will be to find the profile that generates the most lift at low speed and I’ll go from there - in fits and starts most likely.
Keep in mind that no airfoil generates much lift at low speed (low air speed that is). The difference is the minimum airspeed at which a foil will generate any lift, the amount of drag at a particular speed, and the total wing area.
Are you planning a VTOL, or STOL craft? VTOL craft generally are considered to have helicopter-like hovering capability, while STOL craft take off like airplanes, but in very short distances, which may be vertical when facing into the wind.
If it works, it will be true VTOL. The problem will be, as with helicopters, maximum velocity. I think there might be ways around that but I’m not going to worry about it until I have a proof of concept.
Thank you again for the info btw.
