Principles of Flight 2024

Front

As angle of attack increases

Back

lift increases and induced drag increases

Front

The Wright Brothers understood that they'd have to find three solutions (objectives) to three problems. Stated simply those solutions were: Yaw, Pitch, Drag; Lift, Control, Thrust; Weight, Drag, Thrust; Parasite Drag, Induced Drag, Total Drag

Back

Lift, Control, Thrust

Front

The function of this control surface is to

Back

yaw around the vertical axis

Front

The purpose of this control surface is to

Back

pitch around the lateral axis

Front

The purpose of this control surface is to

Back

roll around the horizontal axis

Front

Airflow over a wing produces pressure differences due to changes in the velocity of the air. This explanation of lift is described by

Back

Bernoulli's Principle

Front

The diagram illustrates the Four Forces Of Flight. Forces that oppose each other are: Lift and Drag, Lift and Thrust, Drag and Weight, Thrust and Drag.

Back

Thrust and Drag

Front

This illustration is actually a clever variation on the more aerodynamically correct:

Back

Four Forces Of Flight

Front

As the angle between the chord line and the relative wind increases

Back

angle of attack increases, lift increases, drag increases

Front

To maintain a balanced thrust force along a propeller blade, which part has a higher angle of attack?

Back

inside (root) of the blade has a higher angle of attack than the tip of the blade
