Flow Around a Circular Cylinder
Flow around a circular cylinder can be approached from the previous example by bringing the source and the sink closer. Then we are considering a uniform flow in combination with…
Velocity Effects on Aerodynamic forces
Aerodynamic forces are generated whenever an object moves through a liquid or gas. From Newton's second law of motion, the aerodynamic forces on the body are directly related to the change in momentum of the…
Density effects on Aerodynamic forces
Aerodynamic forces are generated whenever an object moves through a liquid or gas. From Newton's second law of motion, the aerodynamic forces on the body are directly related to the change in momentum of the…
Bernoullis Equation
In the 1700s, Daniel Bernoulli investigated the forces present in a moving fluid. This slide shows one of many forms of Bernoulli's equation. The equation appears in many physics, fluid mechanics, and airplane textbooks.…
Factors that affect Aerodynamics
When a solid body is moved through a fluid (gas or liquid), the fluid resists the motion. The object is subjected to an aerodynamic force in a direction opposed to the motion…
Inviscid flow
Inviscid flow is the flow of an inviscid fluid, in which the viscosity of the fluid is equal to zero. Though there are limited examples of inviscid fluids, known as superfluids, inviscid flow has many…
Maximum Flight Altitude, Absolute and Service Ceilings
The RC information can be used to estimate the flight altitude that can be reached by an airplane. Again, we use the Messerschmitt fighter as an example. Clearly, the RC…
Maximum Range of a Subsonic Airplane
We complete this brief set of applications of basic aerodynamics by estimating the range of a propeller-driven aircraft. The key here is to introduce the rate at which fuel is…
BASIC AERODYNAMICS
Although the material covered in this book is a necessary prerequisite for understanding basic aerodynamics, it is important to realize that the principles set forth may not be directly applicable…
