Wingipedia: "acrobatics" through "induced drag."

Aviation has a language all its own; "aviationspeak" if you will. To keep up with the terminology, and the times (you've probably use Web-based Wikipedia), we've developed our own aviation-based directory of terms, Wingipedia. In our first edition, we covered "acrobatics" through "induced drag." Our second installment continues with "Jenny" through "roll." If you'd like to add to our aviation encyclopedia or you think that we've omitted anything, this is the space to add your two cents.

I enjoyed the first installment of Wingipedia. The only comment I have is to point out that dihedral effect is due not to the increase in projected area on a wing that is lowered, but to the change in induced angle of attack resulting from the normal flow component when the aircraft is in uncoordinated flight.
Think of the effect of dihedral on an aircraft in a coordinated level turn--nil, right? Now think of the effect of left rudder on an aircraft already in a 10 deg. left bank--the bank angle will increase.
This is the definition of dihedral effect--the rolling moment derivative with respect to sideslip angle.

Genoa, WA
I remember the first Luscombe to come to our area,(central Montana),70 years ago. We were told it was the first all metal airplane, it was affectionately dubbed- "The flying tin can". That was the one that stirred my desire to fly.

Your Wingipedia is missing "pilot", without which there would be no need to fly. Also, "plane", short for airplane but more specifically it is a geometric definition of a flat two-dimensional shape. The airplane got its name because of the fact that flight moves along a "plane" in space, didn't it?



"lift"

"land"

"prop wash"

"rate of turn, climb"

"red-right-returning"





Thanks for your magazine,

Regarding the comment that "Alberto Santos-Dumont made the first public European flight of an airplane in Paris in 1906. Long before the Wrights did, he routinely launched his aircraft without the aid of catapults. His dainty little Demoiselle of 1909 might well be considered the first practical lightplane."

Compared to what the Wrights did, Santos-Dumont is a footnote in aviation history. The Wrights flew the first powered controlled flight in the world on Dec 17, 1903. They went on to fly in France in 1908 many public demonstrations, including carrying passengers, flying for more than an hour. Harry Combs book "Kill Devil Hill" details the history of early aviation in great detail (including the mistakes Lilienthal made in his lift tables).

The Wrights discovered, in a wind tunnel they constructed, the correct values for lift, drag and the Smeaton pressure coefficent of air to be 0.0033, not 0.0055, remarkably close to the figure used today (0.00289) and explains why the lift they saw at Kitty Hawk was only 62% of what it should have been. They went on to discover so many of the basics of aeronautical engineering, these two men with no education except what they taught themselves. They rebuffed the majority of scientists who said man would never fly a heavier than air machine, certainly not a powered machine.

I really like when people are expressing their opinion and thought. So I like the way you are writing
