Hello everyone!
I'm a long time lurker who wants to give a bit back to the amazing community so follow along as I prototype up my first edf airplane.
Stuck in a hotel for a few weeks down in Iowa so its the perfect time to work on an idea I have been kicking around for a long time, the foamboard He162!
From wikipedia.
"The Heinkel He 162 Volksjäger (German, "People's Fighter"), the name of a project of the Emergency Fighter Program design competition, was a German single-engine, jet-powered fighter aircraft fielded by the Luftwaffe in World War II. Designed and built quickly, and made primarily of wood as metals were in very short supply and prioritized for other aircraft, the He 162 was nevertheless the fastest of the first generation of Axis and Allied jets."
The ideas/thoughts:
-huge nacelle for edf
-simple wing shape
-3 channel?
-based on existing designs if possible
-uses low cost 64mm edf
-moderate wcl
-around 2 sheets of dtfb
-few other designs of the 162 (might be a reason?!?!)
-easy to build
-removable wing
Start:
Being a huge fan of the dtfb Bugatti I stretched and stretched and scaled the wing out to 32in to get a rough resemblance of the 162 profile. I was hoping to do a bit larger of a wingspan but the 32in span is about the max that will fit on a standard sheet of foam. hopefully this keeps the wcl around 9-10 and makes it a bit more friendly for a noob pilot like myself. for the wing tips i just eyeballed the downturn, will have to make up a template for rev 2. As a side not I'm unsure if its just the batch of dtfb but the stuff with the black paper seems to delaminate much easier than the regular stuff, this will need to be redone at some point but will do for a proof of concept and hopefully initial flights.
Wing pre fold
Just for kicks i overlaid the bugatti fuselage over the 162 blueprints and its fairly close!! couple of minor mods and some stretching and we seem to have something workable. The final design will have a few 3d printed parts to help with the styling but those will have to wait until I'm home again.
Trying to get the feel for how it will look assembled
Since I dont have time to reinvent the wheel I scaled the edf section from the AP Eazy ducted fan from 50mm to 64mm and stuck it to the top of the wing. Added in a rough tail section and a couple of servos to the bottom of the wing and Here is how it sits as of this evening.
To do:
-pushrods
-attach wing
-radio setup
-battery tray
-nosecone
-first flight
Cheers!
