AVIT 323 FINAL TEST- DILSE (ACTUAL / ) QUESTIONS
AND VERIFIED ANSWERS (100 %SCORE) A+ GRADED
Total Drag curve changes:
Weight-Which drag affects it? - ---Answers----Affected only from the induced drag side -Curve shifts upwards
Total Drag curve changes: Configuration - ---Answers----
Affected only from the parasite drag side Curve shifts more to left and up -Parasite drag increases, total drag curve increases
Total Drag curve changes: altitude - ---Answers---Curve
shifts to the right -If density goes down, velocity has to go up -Both parasite and induced drag
which type of drag will change when aircraft goes into ground effect - ---Answers---Induced drag will go down -While in ground effect, upwash and downwash will reduce, and lift will shift forward
Aspect ratio -related to induced drag - ---Answers---The area of the wing- Gliders- bigger AR 1 / 2
HIGH Cdi at LOW AR LOW Cdi at HIGH AR
Which of these factors affects induced drag the most? - --- Answers---weight
Induced drag variables: weight increases - ---Answers---
Induced increases
Induced drag variables: Aspect ratio increases - ---Answers--
-Induced drag decreases
Induced drag variables: speed increases - ---Answers---
Induced drag decreases
Induced drag variables: altitude increases - ---Answers---
induced drag increases
Induced drag variables: lift increases - ---Answers---Induced
drag decreases
Wheel friction force - ---Answers---More weight on wheels will make the force more
