drag coefficient prediction chapter 1

drag coefficient prediction chapter 1 the ideal force acting on a surface positioned perpendicular to the airflow is equal to a dynamic pressure, denoted by ' q ', times the area of that surface. dynamic pressure is one-half the square of the flow velocity times the density of the fluid. in equation form this is: 2 2 1 vqρ= where,=ρair... The existence of thrust, or lack thereof, can have a significant effect on the rocket's drag coefficient for blunt aft bodies, as in the case above.

How rockets work

20 in simple language, newton's laws of motion: first law objects at rest remain at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force. second law force equals mass times acceleration(or f = ma). third law for every action there is an equal and opposite reaction. before looking at each of these... Within the atmosphere, drag is an important unbalancing force. that force is virtually absent in space. a rocket traveling away from earth at a speed greater than...
