🚀Controlling drag is essential for a successful space shuttle reentry.
📐Angle of attack and bank angle are key parameters in controlling drag.
🔄Roll reversals are used to control cross-range during reentry.
🛬The objective is to safely land the space shuttle on a runway.
🔒Aerodynamic constraints limit the range of control during reentry.
What is the purpose of reentry guidance in space shuttle missions?
—Reentry guidance ensures a safe landing of the space shuttle by controlling drag and cross-range.
How are drag and cross-range controlled during reentry?
—Drag is controlled using angle of attack and bank angle, while cross-range is controlled using roll reversals.
Why are roll reversals necessary during reentry?
—Roll reversals help maintain the desired cross-range capability of the space shuttle.
What are the main objectives of space shuttle reentry?
—The main objective is to bring the space shuttle safely back to Earth and land it on a runway.
What are some of the limitations in controlling drag during reentry?
—Aerodynamic constraints and thermal limits impose limitations on the control of drag during reentry.
