Chapter 9

9.1 What is weather cocking?

9.2 If a rocket has a vertical velocity of 17 m/s and the crosswind velocity is 1 m/s

what is the weather cocking angle?

9.3 In Exercise 7.2 what is the lost height due to the crosswind?

9.4 Why did the Saturn V rocket have several tons of baffles installed inside the

propellant tanks?

Travis S. Taylor 57

9.5 Define slosh.

9.6 Write a computer code to model the precession of a rocket due to vorticity in the

9.7 In our discussion of vorticity we neglected friction of the propellant fluid with the

inner tank surface. What effect would this friction have if not neglected?

9.8 We discussed tornadoes and overpasses. With that discussion in mind why is it

usually not a good idea to open both the front door and the balcony door of a

beachfront condo at the same time?

Travis S. Taylor 58

9.9 How much energy would be imparted to a rocket if it had a head-on collision with

9.10 Why was the mass fraction of the Atlas rocket better than its competition at the

time?

9.11 What does monocoque mean?

9.12 Discuss the systems engineering processes in Chapter 6 in comparison with the

SMAD process. Be sure to explain why and where the SE processes fit in the SMAD

and vice versa.

9.13 Why is using heritage designs from Apollo and Space Shuttle era programs a

good idea for the Constellation program? (hint: paperwork)

Travis S. Taylor 59

9.14 How does the new Ares rocket design immediately improve safety by reducing

the falling foam risk of the Shuttle if it still plans to implement ET like components?

9.15 Discuss the overall holistic subject matter and talent pool required for the rocket

scientist and/or engineer.

9.16 Name at least one impact on other programs and/or technologies cancellation of the

Space Shuttle program had.

Travis S. Taylor 60

9.17 Why are Dinosaurs extinct?

9.18 MOST DIFFICULT PROBLEM IN THE BOOK: Use all the information in this

book and at https://en.wikipedia.org/wiki/Falcon_9_full_thrust to create a calculation and

simulation of the Falcon 9 Full Thrust. Determine the fineness of the rocket as well as an

estimate on the critical pressure. Make assumptions where information is not available.

Also, complete a PRA for the rocket at the block diagram level and thus creating a RBD.

Determine using techniques like in the Mathcad code in Chapter 7 how loss of engines

from 1 to 9 will impact delivery of maximum payload to orbit.
