What are the three types of parasite drag?

The correct answer identifies the three types of parasite drag as form drag, interference drag, and skin friction.

Form drag is created due to the shape of an object as it moves through the air. This drag occurs because the air cannot smoothly flow around the body of the aircraft, leading to a pressure differential between the front and rear of the object. It is particularly significant for objects with a larger frontal area or less aerodynamic shapes.

Interference drag arises when two or more parts of the aircraft interact with each other in a way that disrupts the smooth flow of air. For example, when airflow around the wings, fuselage, and tail combine, it can result in additional drag due to turbulent flow patterns that may not exist if those components were isolated.

Skin friction drag is associated with the viscosity of the air acting upon the surface of the aircraft. It is the result of the friction between air molecules and the surface of the aircraft and generally increases with the surface area of the object and the speed of the flow.

This explanation conveys the reason why the correct answer encompasses the types of drag specifically categorized under parasite drag, pertinent to aerodynamics and aircraft design. Other choices incorporate terms that relate to drag with different characteristics, but they do not accurately represent the
