# What are the four principles of aerodynamics?

## What are the four principles of aerodynamics?

The four forces of flight are lift, weight, thrust and drag. These forces make an object move up and down, and faster or slower. How much of each force there is changes how the object moves through the air.

What are the four forces of flight quizlet?

Terms in this set (46)

• What are the four forces? Lift, weight, thrust, drag.
• Lift. created by the airflow over and under the wing.
• weight. due to gravity, opposes lift.
• thrust. propels the airplane forward.
• drag. backward force limiting speed, opposes thrust.
• vector arrows.
• equilibrium.
• newtons first law.

What are the principles of flight?

Principles of Flying. (1) Lift, (2) Gravity force or Weight, (3) Thrust, and (4) Drag. Lift and Drag are considered aerodynamics forces because they exist due to the movement of the Airplane through the Air.

### Who identified the four forces of flight?

Cayley
Cayley discovered and identified the four aerodynamic forces of flight—weight, lift, drag and thrust— and in 1799 took the crucial step of separating the system of thrust from the system of lift.

What is aerodynamics flight?

Aerodynamics is the way objects move through air. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air is affected by aerodynamics, from a rocket blasting off, to a kite flying.

What are three key aerodynamic principles?

Q. What are three key aerodynamics principles? Drag, height, & acceleration.

#### What forces affect an aircraft in flight quizlet?

There are four forces that affect flight; lift, drag, weight and thrust. A force that pushes objects upward. A force that pulls an aircraft down.

What is form drag quizlet?

Form Drag. Drag due to the pressure imbalance in the drag direction caused by separated flow. Interference Drag. Pressure drag caused by mutual interaction of the flow fields around each component of the airplane.

Which of the 4 forces of flight opposes weight?

lift
Thrust opposes drag, and lift opposes weight. For an airplane to fly, thrust must overcome drag, and lift must overcome weight.

## What force makes an airplane turn?

The horizontal component of lift is the force that pulls the aircraft from a straight flight path to make it turn. Centrifugal force is the “equal and opposite reaction” of the aircraft to the change in direction and acts equal and opposite to the horizontal component of lift.

What are the four forces?

The Four Fundamental Forces of Nature

• Gravity.
• The weak force.
• Electromagnetism.
• The strong force.

Which of the four forces of flight has the biggest impact on flight stability?

Perhaps the most importance force to a pilot is lift. Lift directly opposes the weight of the aircraft to keep it aloft. As the aircraft moves faster, lift increases until its force is equal to weight.
