| Description | The paper first deals with the origin of aerodynamic lift and offers two possible explanations for its existence. Both interpretations use only Newton's laws of motion and do without Bernoulli's equation. The simplicity of the argumentation allows their use in high school. The following text describes the flight of birds, the importance of flapping wings and the formation of flight. When describing the flight of insects, the causes of the differences between small and large fliers are commented and the main mechanisms that increase the buoyancy force of small fliers above the value usual for larger birds and aircraft are elementary. The appendix to the text draws attention to some difficulties in interpreting Bernoulli's equation. |
