3241: Aerodynamics and Flight Mechanics Name: _________________ Concept Quiz #5 Consider again the example of the rocket on a thrust stand discussed in class. An actual rocket in flight is not attached to a thrust stand and is free to rapidly accelerate through the atmosphere and into orbit. The momentum equation complete describes this motion. ( 29 = + F dS n U U dV U dt d S V ˆ ρ Look again at the rocket on the test stand, but now assume that the test stand connection with the rocket breaks and the rocket is free to accelerate to the left, as shown in the drawing below:

Unformatted text preview: Using the given parameters in the figure and taking a control volume that is fixed to the rocket and accelerates with it, what is the time rate of change of momentum (first term in the momentum equation) within the control volume? Is there still an external force, F x , for this control volume? If this rocket were in a vertical orientation, what additional force might you consider on the right hand side of the momentum equation? V(t) M(t) x y P e A e V e e...
