Project Title: Determining the efficiency of supersonic objects

 

 

Our Progression: Thus far, we have researched supersonics and the factors pertaining thereto. These factors include, but are not limited to, drag, lift, and fuel consumption. These factors are all relative to the speed achieved by the object in question.

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 Lift
