Like many people, I've recently been fascinated by the lives and affections of the ruling classes of Westeros. Westeros spends a lot of time arguing about who is in charge, with its occasionally charming residents. Game of Thrones is a lot of fun, but don't get attached to any one character because their lifespans in the world seem to fluctuate quite a bit.
One of many up-and-coming rulers, her Daenerys Targaryen spends much of her time riding dragons from time to time. My background as an aeronautical engineer inspired her to think about mythical creatures. They realized that in order for them to fly, their world had to function a little differently than Earth.
It is possible to estimate the size of the dragon compared to Daenerys, who appears to be about 1.6 m (5 ft 3 in) tall and about 60 kg (132 lbs). A dragon's body is about four times as long, about five times as deep, and about twice as wide, and its tail is about the same length and thickness as its body. Assuming that dragons and females have approximately the same density, a full-grown dragon should have about 44 times the mass of Daenerys, or about 2,600 kg (5,700 lbs).
Considering that everyone in Westeros seems to move the same as on Earth, let's assume the same gravity pushes the dragon's weight up to what he calls 26,000 Newtons (let's call it W). meters/second/second (32 feet/second/second).
To understand the aerodynamics of kite flying, he needs two additional pieces of information. Wing area first. Two 4 x 8 m (13 x 26 ft) or 64 m2 (340 ft), which we call the wing S, as each wing appears to have a wingspan about twice the length of the dragon's body Let's approximate it as a rectangle of .
Then there is the deceleration speed, the slowest speed the dragon can safely fly before it falls out of the sky. It is reasonable to assume that kites take off and land at near-stall speeds, just like airplanes and birds. Judging by the program, a kite body length of about 13 m is finished in about 3 seconds, giving a stall speed of about 4.3 m/s (14 ft/s).
