Click to edit Master subtitle style Virginia Tech 1. As you slow down below the minimum drag speed, why do you need to add more thrust to maintain level flight? 2. What is the coefficient of pressure? 3. How does thrust required vary with altitude? 4. What dictates the minimum and maximum velocity you can fly at at a given altitude? 5. How does thrust available vary with velocity for a turbojet? 6. How does power available vary with velocity for a propeller? 7. What is power? 8. How do you compute the rate of climb? 9. How does thrust available vary with altitude? AOE 2104--Aerospace and Ocean Engineering Fall 2010 30 Sept 2010 Lecture 7
