Using The Ternary Closed-loop Model to Research on pterosaurs' flight capability

Abstract

In this article, through the pterosaurs Flying Model and The Plotting of The Growth Curve and The Ternary Closed - loop Model to verify The ancient pterosaurs and The rationality of The ability to fly, and when using The albatross flight mode pterosaurs can reach maximum wingspan and weight. In the flight model, we simplified the relationship between flight flapping and energy to obtain the energy consumption of flight. In The Ternary Closed loop Model, we considered The energy acquisition in The modern sense and finally calculated and obtained the maximum territory for pterosaurs. The largest territory also verified that pterosaurs had enough food to obtain energy. And according to the relationship among territory, energy consumption and body weight, we can use any two parameters to figure out the other parameter.
