I want to know about how to get more lift from aircraft wings without increasing engine power and wingspan.
I have said "without increasing wingspan" and you haven't noticed that part.berkeman said:Welcome to the PF.
How about this?

I think using Coanda effect can help but don't know about any real example of using that.Greg Bernhardt said:What are your ideas so far?
Of course I did. That's why I went "up" instead of "out"...T C said:I have said "without increasing wingspan" and you haven't noticed that part.
How much reading have you been doing at the NASA pages on wing geometry and design for different flight profiles?T C said:I think using Coanda effect can help but don't know about any real example of using that.
Increase the angle of attack.T C said:I want to know about how to get more lift from aircraft wings without increasing engine power and wingspan.

Nah, you just fly slower...boneh3ad said:That would increase engine power on account of increased drag.

That is a good place to start. The references at the bottom of the article point to more advanced sources. The wiki article features "thin" as a strategy for better airfoils. I'm sure there are dozens of other ways too.

We know. We're just trying to draw the OP out of his/her shell...Dr.D said:This works, up to a point, after which the wing stalls. Also, drag increases requiring more engine power.
How can you say that jets are necessary for Coanda effect?boneh3ad said:I am not sure how you intend to utilized the Coandă effect without a jet of some sort. It doesn't apply to a typical flow over an airfoil.

If you have a propeller for your plane's propulsion, what is the source of all of that pressurized air for the wings? Some heavy air compressor added to the aircraft?T C said:This wikipedia explanation is enough for me.
Pressurised air is used in static application i.e. to get a flow of air. Do you want to mean that if the air flow is created by a blower, then Coanda effect wouldn't occur there?berkeman said:If you have a propeller for your plane's propulsion, what is the source of all of that pressurized air for the wings?

Sorry, I've tried a few times, but I'm not able to parse what you wrote there.T C said:Pressurised air is used in static application i.e. to get a flow of air. Do you want to mean that if the air flow is created by a blower, then Coanda effect wouldn't occur there?

TC, When you say wing span are you only referring to the width of the wing from root to outer wing tip, or you referring to all wing geometry?T C said:I want to know about how to get more lift from aircraft wings without increasing engine power and wingspan.
pyroartist said:Fact: There are more flying wings in use today than all commercial aircraft combined. Hang gliders and paragliders are tailless, flying wings and are enjoyed all over the world.

pyroartist said:or just use a laminar airfoil and very smooth surface finish.
