Propeller blades
Today I decided to get a start on my actual propeller blades. This took way longer than expected.
I used many different aerofoils throughout the propeller’s length as the speed experienced at each length is different.
NACA 4424 for the propeller root as its thickness provides structural strength
Goe 387 for the lower midsection as it has a decently high stall angle
NACA 4412 for the upper midsection as it has low drag and high lift coefficent
NACA 2412 for the blade tips as its thin profile provides low drag at high speed
The loft command in solidworks was solid-not-working, making this a major headache.
Next i plan to work on the lock for the back of the gearbox and hopefully on the secondary propellers, I hope the bevel gears don’t take me 6 hours to figure out how to make to ISO specs :/
