Project Title: Determining the efficiency of supersonic objects
Our Problem: The efficiency of supersonic objects is low. To achieve these speeds, too much fuel and energy is used.
Our Solution: To create a program using the proper mathematical equations to determine the most efficient object traveling at supersonic speeds. The models are as follows:
Drag - The retarding force exerted on a moving body by a fluid medium such as air or water. Drag equation = c x S x 1/2rV V = Velocity D = Drag C = Coefficient of Drag S = Area of Object r = Air Density C = Coefficient of Lift This equation can be re-written using Parasite and Induced Drag Equations: D = (C + C ) x S x 1/2rV Parasite Drag - definition unavailable at present. D = Cd x S x 1/2rV Induced Drag - definition unavailable at present. D = Cd x S x 1/2rV Total Drag - D = D + D Lift - The component of the total aerodynamic force acting on an airfoil or on an entire aircraft or winged missile perpendicular to the relative wind and normally exerted in an upward direction, opposing the pull of gravity. Lift equation = C x S x 1/2rV V = Velocity D = Drag C = Coefficient of Drag S = Area of Object r = Air Density C = Coefficient of LiftSources: http://dictionary.reference.com/
