WebbDrag is a force that opposes motion due to an object's shape, material, and speed. This project defined what drag force is, derived the governing equation for drag and listed … WebbThis resistance is called drag. Drag is the result of a number of physical phenonmena. Pressure drag is that which you feel when running on a windy day. The pressure of the wind in front of you is greater than the pressure of the wake behind you. Skin friction, or viscous drag, is that which swimmers may experience.

"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. " - Shape effects on drag nasa

Webb16 nov. 2024 · The effect of accommodation shapes on wind drag acting on hull of the ship has been investigated. Using the proposed frontal accommodation shapes, up to 30% of the total wind drag in head wind (N1), and up to 66.88% of the total wind drag acting on the hull at a Reynolds number of 8.65 × 10 7 in head wind (N3), could be reduced. WebbThe satellite design incorporates a “form follows function” approach with a cylindrical shape and conductive body-mounted solar arrays to minimize drag and perturbations to the space environment. Atomic-oxygen resistant materials are utilized and a passive thermal design with heat pipes and radiator panels minimizes the impact of aero-heating.
