Like, the coanda effect for example. Though propwash has been "kinda simulated" in sp, shown here in JamesPLANESii's J-3 Cub. Basically, it's just a hidden underpowered jet engine on it's control surfaces.
Now you may wonder why I asked this, because I'm trying to remaster my PC-2A into a PC-2B, which is an improvement. It has the same engine placement design as the ShinMeiwa US-2, stated here;
The Shin Meiwa US-1A flying boat utilizes a similar system, only it directs the propwash from its four turboprop engines over the top of the wing to generate low-speed lift. More uniquely, it incorporates a fifth turboshaft engine inside of the wing center-section solely to provide air for powerful blown flaps. The addition of these two systems gives the aircraft an impressive STOL capability.. (Taken from wiki's coanda page lmao).
To explain the coanda effect in a simpler way, Moving air sticks to a surface(no matter what kind). So, if you have an engine that produces a lot of thrust, you can stick that engine on top of the wing. Giving you a high speed air on low speed flight. I'm still trying to understand this thing instead of actually advance studying for college 💀🙏
(Big edit to delete a lot of stuff) I read the thing a few times and tried to write it, but I don't understand it fully xdd
.
I think that the jet itself has low pressure as it is fast. And due to fluid viscosity and flow/pressure effects, surrounding air speeds up and decreases in pressure as well. Far away, the air maintains atmospheric pressure. This makes an axial pressure gradient with higher pressure on the outsides and lower pressure in the middle.
.
If one side is then blocked, it will always be at low pressure since there is no air there to form the usual pressure gradient. The new pressure gradient has lower pressure near the surface, and higher pressure at the free side. The pressure difference means that the jet experiences more force on the free side, and will tend to move towards the surface. This is much stronger than any passive airflow effect, and you can push the jet around sharp curves.

The simple does not have coanda effect. The wings only consider angle of attack afaik
@MonsNotTheMonster oh, well I have no clue
@CARSnBULL Fast air sticks to surface. That's the simplest way I can explain it :v
I have no clue what that is
