FOUR FORCES OF FLIGHT

FOUR FORCES OF FLIGHT - A CLOSER LOOK

FLY HOPPER

Lift

The force that allows an aircraft to take off and remain in flight. An airplane’s wings help it create lift, and rotorcraft, including our Hopper drone, use propellers to generate lift. Lift is created when airflow passes over and under an airplane's wing or a propeller's blades, which are shaped much like wings.  





Weight (Gravity)

The force caused by the downward pull of gravity and acts directly opposite of lift. Since gravity is always acting, lift must be constantly generated to keep aircraft in the air. The more an aircraft weighs, the more lift it requires to fly. 





Thrust

The force that causes an aircraft to move forward and allows its wings to create lift. For the drone, thrust is the force that the propellers direct downward to allow it to climb, hover and maneuver. Thrust is created by a propulsion system such as a jet engine or a motor turning a propeller. It varies with the amount of power being applied.





Drag

The opposite of thrust and is the force that acts against an object in motion. The atmosphere works against an aircraft in flight in the form of friction caused by air pressing against the aircraft while in motion. Drag is the reason airplanes are built in a streamlined manner with clean, smooth lines allowing air to pass by more easily.





Aerodynamics

The science of how objects move through air

Altitude

The height of an object in relation to sea level or ground level

Aviation

Flying within the Earth’s atmosphere

Drag

The force that acts against an object in motion

Flight

Flight is the process of moving through the earth’s atmosphere (or beyond) without touching earth’s surface.

Hover

To remain in one place in the air - all forces of flight must be equal

Lift

The force that causes an aircraft to rise while in flight; created when air passes over and under an airplane's wings

Pitch

The movement a drone makes along the lateral axis

Roll

The movement a drone makes along the longitudinal axis

Space Flight

Flying through the vacuum of space is called Space Flight.

Thrust

The force that allows an aircraft to move forward; allows an aircraft to overcome weight and produce lift; created by a motor turning a propeller

VLOS

VIsual Line of Sight - drone is visible to the pilot without any devices like binoculars
