It is called aerodynamic drag, or just "drag"
Why did you give the subject title as "inventors"?
The resisting force exerted on an airplane is called drag. Drag is the force that opposes the forward motion of the airplane through the air. It is caused by the interaction of the airplane's surfaces (such as wings, fuselage, and other exposed parts) with the air molecules in its path.
To calculate the drag force on an airplane, several factors need to be considered, including the shape and size of the aircraft, its speed, and the air density. The drag force can be calculated using equations such as the drag equation, which takes into account the aircraft's drag coefficient (a measure of its shape's resistance to airflow), the air density, the velocity of the aircraft, and the reference area (the effective area perpendicular to the direction of motion).
The drag force limits the speed and efficiency of an airplane. Aircraft designers aim to minimize drag by employing streamlined shapes, reducing surface area, and using aerodynamic features like winglets to reduce drag-inducing vortices. Additionally, pilots can adjust the angle of attack (the angle between the wing chord line and the oncoming airflow) to optimize lift and minimize drag at different flight conditions.
