Parasite
Drag
Drag
This type of parasite drag is caused by the shape of the aircraft and its components.
What is Form Drag
Induced drag is a byproduct of this force that opposes gravity.
What is lift
This type of drag is influenced by the smoothness of the aircraft’s surface.
What is Skin Fraction
This force acts opposite to the direction of motion and slows the aircraft down.
What is Drag
This part of the aircraft generates lift.
What is the Wing
Parasite drag is broken down into what two components?
What is Form Drag and Skin Fraction?
Induced drag increases with this angle of the aircraft.
What is the angle of attack?
What does Skin Fraction refer to?
The tendency of air flowing over a body to cling to its surface
This force propels an aircraft forward.
What is Thrust?
This component controls the pitch of the aircraft.
What is the elevator
By what is Parasite Drag caused by?
By those parts of the aircraft that do not generate lift such as the fuselage, landing gear, struts, antennas, wing tip fuel tanks, etc.
When the pilot uses control surfaces, they produce what?
What is form drag and induced drag
Form drag is also known by this term, which describes the resistance due to the shape of an object.
What is pressure drag?
This force pulls the aircraft downward towards the Earth.
What is Weight?
This part of the aircraft is used to control roll.
What is the aileron
What adds to Parasite Drag?
Any drag caused by openings, such as those in the cowling and those between the wing and the ailerons and flaps
Induced drag is caused by these swirling air patterns generated at the wingtips.
What are vortices?
Which type of drag is primarily increased due to the layer of dirt and bugs on the aircraft’s surface?
What is Skin Fraction
What limits an aircraft's performance and why?
Drag does limit an aircraft’s performance. However, drag also allows the pilot to control flight because an aircraft turns by increasing the drag in certain areas using control surfaces that push on the passing air.
This part of the aircraft houses the cockpit and passengers.
What is the fuselage
How can Parasite Drag be reduced?
Remove parts of the aircraft that cause it.
Streamline those parts that cannot be eliminated.
This aerodynamic feature can help reduce induced drag by altering the airflow at the wingtips.
What are winglets?
This type of drag is most significant at high speeds and is a major component of total drag.
What is Form Drag
The various forms of drag change with different flying conditions and, in general, increase what
What is Speed?
This component helps stabilize the aircraft in flight.
What is the vertical stabilizer?
