What Effects Do Aerodynamics Have on a Drone?

Due to the rotational movement of the props or the displacement of the aircraft, an airflow passes over the wings or the propellers. This causes a pressure increase below the profile & a pressure decrease above the profile of the wing or propeller.

Aerodynamics is something quite complex, & is actually the science that focuses on the study of flows of air & other gases.

Given the difficulty of the matter, & because it is only partly relevant, we will only briefly discuss this, but do not hesitate to contact us if you have any questions about this.

Different types of aerodynamics:

In aerodynamics we talk about 2 different types of forces when an object is in the wind.

The first concerns the prevailing wind. This is there when an object is also in a fixed place.

The other force is the relative wind, & it forms when an object moves through the air in combination with the prevailing wind.

When a drone is in the air it will always be the relative wind that applies.

Even without wind, forces will apply to an object. For example, there is gravity, & the reaction force or lift that prevents the aircraft / drone from falling down.

In addition to a lot of other forces that apply in practice, it is mainly the pull or thrust of the propellers in the form of a reaction force that causes the drone to move upwards. This pulling force works against gravity. Something similar happens with both aerofoils & propellers.

Due to the rotational movement of the props or the displacement of the aircraft, an airflow passes over the wings or the propellers. This causes a pressure increase below the profile & a pressure decrease above the profile of the wing or propeller. This is converted into a force that keeps the aircraft in the air. The difference in under & over pressure is made by the split just before the aerofoil. The shape makes it easier for the air to pass under the profile than above it, creating a pressure difference.
