It can be reduce by streamline as many of the parts as possible, by using fairing , surface of aeroplane cleaned and polished.
winglet
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.
The edges of airplane wings cause vortices, in other words, a trail of air turbulence, usually in a spiral pattern. It was discovered that this actually adds extra "drag" on the airplane (wind resistance that the airplane must push through). Engineers found that by adding these "winglets", or "wingtip devices", the vortices were reduced, which reduced drag on the airplane, and this allowed greater fuel efficiency, which is important for commercial aviation.
Air drag can be reduced by improving riding posture and the use of tight fitting slick clothes.. Mechanical drag can be reduced by the use of high quality bearings.
The commonly used fuselage shape allows the aeroplane to move forward through the air at a reduced drag. And the sectional shape of the wings create lift.
Drag slows the forward movement of aircraft.
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
The drag of an airplane is the air resistance caused by the plane flying through air. Similar to when you pull your hand through water and feel resistance.
Flaps would increase drag increasing your speed will increase it even more
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.
