Flight Controls Flashcards
1
Q
Adverse yaw
A
During banking, high wing more lift and drag, causing slow down
Pronounced at low airspeed
2
Q
Reduce adverse yaw
A
Differential aileron
Frise-type aileron
Coupled ailerons and rudder
Flaperons
3
Q
T tail
A
- Above downwash from wing and prop
- Reduce noise and vibration
- Move greater distance to raise nose, greater force
- Moment arm causes high loads, create flutter
- Susceptible to deep stall
4
Q
Stabilator
A
Uses a riser antiservo to reduce sensitivity
5
Q
Canard
A
Creates lift, nose up, less drag
6
Q
Types of flaps
A
Plain
Split
Slotted
Fowler
7
Q
Slotted fowler
A
Increase lift coefficient
When lowered, high energy air from lower surface through slot to upper.
Accelerates upper boundary layer
Delays airflow separation
8
Q
Leading edge devices
A
Fixed slots
Movable slats
Leading edge flaps
Leading edge cuffs
9
Q
Trim systems
A
Trim tabs Balance tabs Servo tabs Antiservo tabs Ground adjustable tabs Adjustable stabilizer
