which airfoil must produce the lift with less than one mach number . that is
called sub sonic airfoil......
Another answer would be : an airfoil designed to perform below the speed of sound.
The antonym for subsonic is supersonic.
the ground is an type of airfoil
It depends on what the airfoil is made of.
The rotor blade is the airfoil on helicopters.
airfoil is important beacause it boils
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
Just like any other airfoil.
A symetrical airfoil is an airfoil that has the same shape on both sides of its centerline and in this type of airfoil : the centerline is thus straight the chord line is the center line the maximum camber is zero the camber ratio is zero

A simple concept in aeronautics is about airfoil to know the shape of airfoil before speaking about about the shape of airfoil i would prefer you to know about airfoi the advantages of using airfioil is $it is the most aerodynamical shape ever designed $if you look at a planes planes wing closely you can notice the shape of airfoil $
The difference between airfoil and airfoil section is that airfoil is a structure with curved surfaces designed to give the most favorable ratio of lift to drag in a flight, it is used as the basic form of wings, fins, and tailplanes of most aircraft. An airfoil section is the cross- sectional shape or profile of an airfoil. I studied that in sixth grade for a model plane that I did a report on. Researching into things that aren't required can help put you farther into life's riches. Hope I helped.
