What are two different ways to change drag on an airplane?
Speed and flaps.
What are two different ways to change drag on an airplane and how would the airplane respond to that?
Flaps would increase drag increasing your speed will increase it even more
How do you change of speed of a toy airplane?
Increase in motor size with a propeller change, reducing drag on the plane
What is the aspect ratio of a high speed airplane?
Low! To minimize the drag which grow with the square of the speed.
How does drag affect a paper airplane?
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
What is the maximum speed an airplane can go?
The maximum speed a airplane can go is a factor of it drag and trust. All planes have a Vne speed witch is the never exceed speed, which is were the amount of drag becomes so great that it will start to damage the aircraft. Many factors have play on this number, such as the camber of the wing, form drag, induced drag, and how strong the frame is. A C-173 Vne is 169, and a SR-22 can go muck 3 or 4. Maximum speed of a airplane is around 1000 km per hour
How the airplane flies?
The airplane flues by using a fast amount of speed to push through the wind. There is also wind pushing back on it. This is called "Drag". If the speed is quick and strong enough, the plane will push through the drag and continue to fly.
Will speeding up decrease the drag force on an airplane?
In general (special exceptions may apply) increase speed = increase drag.
What are the amounts of lift and drag for a airplane?
The amounts depend on the airplane's size, shape, speed, altitude, and angle of attack, among other things.
What happens as the pilot gets closer to the speed of sound?
The airplane becomes more difficult to fly because there is more drag from air molecules
How can you maximize the lift to drag ratio of an aircraft?
Fly the airplane at L/Dmax speed. This is also know as best glide. This speed is found in the POH and represents where induced and parasite drags are at there minimal values for the airplane.
Air rushing against an airplane is an example of friction?
Yes, air rushing against an airplane is an example of friction. This force is called drag. It reduces the speed of the plane.
