Aircraft Design, Weight Estimation

1. assessment problem due after one week, March 21, 2022

2. Exercise due after one week, March 9, 2022 1- Determine W TO ,W E and WF for this airplane mission 2- Find W TO varies if cruise V changes from 250 nm to 200 nm and from 250 nm to 300 nm 3- write excel sheet code to determine the following gross weight sensitivity parameters

3. 4- Then calculate the these derivatives for this problem aircraft mission segments 5- In the above twin propeller mission phases, what is the most effective and least effective parameters to minimize aircraft weight? 6- If we want, in design phase, to increase the range by 100 mile, increase flight endurance time by 0.5 hr, increase velocity by 20mile/hr, decease cp by 0.1 increase propeller efficiency by 0.1 and increase L/D by 2 . Calculate the variation in the design gross weight
