To reduce the drag
Airplanes try to reduce drag so they can cut back on fuel costs, and shave time off their route.
the drag of air craft is reduced by aerofoil design, retractable under carriage besides advanced augmentations.
A boattail is the progressively narrowing rear end of a bullet or ballistic missile which is designed to reduce drag.
Because that helps to reduce 'drag' and lets the aircraft move faster.
don't drag it copy and paste it
drag is minimized by aerofoil shape. drag is a force acts on aircraft to minimize speed
it doesn't
By streamlining the aircraft.
The Wright Brothers designed the plane themselves.
Drag
A wing that is swept back reduces drag, but sacrifices stability at low speeds. Straight-winged aircraft produce the most drag, but are the most stable at low, landing speeds. The F-111 and F-14, with variable geometry wings, benefit from both aspects.
