In addition to delta wings, there are straight wings, where the leading and trailing edge are both 90 deg to the fuselage, there are tapered wings, which start 90 deg to the fuselage and, typically, the trailing edge of the wing tapers forward to the direction of flight. And there are swept wings, (usually tapered,) where the leading edge of the wing sweeps towards the tail of the aircraft, allowing for a longer wing and less profile drag, meaning greater lift and increased economy for the speeds expected in cruise flight.

Another interesting thing to note is diehedral. Most aircraft have some diehedral built into the wings. Diehedral is the upward angle of the wings from the fuselage to the wing tip. This provides greater flight stability.

Low wing aircraft, (with the wings mounted at the bottom of the fuselage,) tend to have a greater diehedral than high wing aircraft because with low wings, the rest of the airframe is sitting on top of the center of lift while the high wing basically hangs from the center of lift.

Think of it this way, if you pound a nail into your wall, you can hang something from it easly. If you drive two nails and set something with a pointed bottom between the nails, it’ll stay where you put it until the nails bend.

Cathedral, used by some fighters and stunt aircraft, has the wings sloping downward from the fuselage. This increases agility and manueverability by allowing the airplane’s weight to use gravity to basically fall over the center of lift in a turn.

To go back to the nail in the wall analysis, try to balance a painting in a circular frame on a single nail.

If a google search doesn’t give you more information on NACS airfoils than you want, www. ntsb.gov, should be able to help you find what you’re interested in.

www.airliners.com will also have more pictures than you ever wanted to see of airplanes and can better illustrate the various wing designs and shapes. High wing aircraft are Cessna from the 140 model to the 208, with the 336 and 337 along the way, Piper Cubs, Tri-Pacers and the like. Low wing aircraft with varying diehedrals include the Mooney M-20, Piper PA-28, anything from Beechcraft, and most jets.

Good luck, hope I helped.

Thanks.

however carbon does not only absorb trace elements but organics as well as inorganics like, metals, ammonia, nitrates/nitrites salts and verious chemicals from the water.

the reason carbon won’t remove lots of ammonia. It’s lifespan as was mentioned is about 2 weeks before it becomes useless. Depending on how many other compounds are in the tank like salts, nitrates/nitrites and various chemicals used to adjust algae, medicines etc the carbon quickly becomes clogged and useless. The padded coating will still remove the bulk waste but the carbon has seen its day. It becomes saturated with these unseen components. While it does remove the bad stuff, it also removes the good stuff.

That is not to say everyone should stop using carbon filters, they serve their purpose and especially for beginners.
Going carbonless as G mentioned is something seasoned fishkeepers already know.

Other colors can really affect the screen of certain viewers, its worth testing and tracking with each color to work out the best.

Or research your market and ask them up front.

You would be doing it for their benefit so I don’t see why they would not be co-operate.
