Pleas tell me show me, how i can make a propeller geometric construktion drawing with pencil, paper and so on, not auto- cad . I know it is a helix , but this is not all . Hochachtungsvoll Lust Johannes
just curious, this doesnt really explain much as to why almost all high performance aircraft have a forward bias sweep (e.g. ww2 aircraft). Spitfires for example started with eliptical wings but transitioned to forward sweep biased wings with rounded tapered edges, and aside from having a heavier engine, there are other designs that also retain their forward sweep even with a mid-mounted engine as the engine upgrades got heavier (such as the P-39/63 family, whose engine lies behind the wing). According to my understanding is that it slightly marginally increases the lift performance/efficiency of the wing near the critical lift angle, but in return stalls become more drastic/sudden, necessitating washout/wing twist.
I have a question. When configuring a tandem wing aircraft on a straight cylinder fuselage.....can both sets of wings be on the same mid wing axis or does the front wings need to be lower than the rear? I have have seen RC planes with both sets of wings on an equal high wing axis but does this also apply to full sized aircraft?
The vertical separation of the wing does not matter much, it is more important to space them out longitudinally. A Canard airplane is a bit like this, with the front "wing" at the same height as the main wing. But the rear wing will always be affected by the flow from the front wing.
@@sonjaenglert thank you for the answer. So to be clear they can be on the same Axis as long as they are far enough apart? Also, could you do a video on the specific benefits of particular wing, tail and fuselage shapes and configurations? You seem very knowledgeable on these topics. Btw the plane I am designing is a fictional fighter plane with a radial engine, straight cylinder fuselage and mid-wing tandem wing design. The plane itself is described in my story as "slow but graceful and maneuverable" as both sets of wing flaps can be used to control pitch and roll. I would enjoy a video regarding a tandem wing configuration of this sort
Don’t know how you don’t have more views Sonja your channel is concise and amazing the world needs more people like you if that’s even possible!
2:25 should be lift distribution instead of local lidt distribution isnt it? Please correct me if im wrong
Really useful.
