Webb1 maj 2013 · Drag increases with downforce, and it decreases with wing span squared. So, you want your wing to be as wide as you can legally run. Large endplates further increase the effective span of the wing, further increasing its efficiency.

WebbFins should be rounded and not have sharp edges. Also, they should be thin as they are just helping the rocket fly straight. If fins are thicker, they expose more surface area perpendicular to the direction of travel which creates more drag. Also, the fins should be swept towards the bottom of the rocket, which again helps to reduce drag. goodman bank and trustWebbReview Paper 1 Aircraft drag reductionÐa review D M Bushnell NASA Langley Research Center, Mail Stop 110, Hampton, Virginia 23681±0001, USA Abstract: The paper summarizes the state of the art in aeronautical drag reduction across the speed range for the `conventional’ drag components of viscous drag, drag due to lift and wave drag. goodman baker insurance agency warrensburg moWebb28 juli 2024 · The Object Geometry has a large effect on the amount of drag generated by an object.
