45
Q

RPM Warnings

A

95%- Steady light low pitch beep
106%- Flashing light/Warning Gong
110%- Flashing light/High pitch

46
Q

Types of drag

A

Parasite- Non lifting
Profile- Friction of rotor blades through air
Induced flow- Production of lift, High AOA
Total drag- Sum of all drag

47
Q

IGE- In ground effect

A

In ground effect- Increased efficiency within 1 rotor disk

-Reduces rotor tip vortices caused by horizontal flow of air along the ground
-Lower pitch angle reduces profile drag and power

48
Q

OGE- Out of ground effect

A

Increased induced flow requires an increased AOI to maintain the same AOA

-More drag on the blades needing more power to hover

49
Q

Dissymmetry of lift

A

Difference in lift between advancing and retreating blades

-Blade flapping

50
Q

Blade flapping

A

Advancing blade flaps up velocity at 3 o’clock with increased induced flow, increased induced flow

Max nose up flap 12 o’clock

Retreating blade flaps down with max 9 o’clock. Decreases induced flow

Max down flap is over the tail, Overall rotor disk is tilted aft (Blowback)

51
Q

Cyclic feathering

A

Fix blowback, Changes the AOI of each blade differentially around the rotor system.

Forward movement advancing blade has decreases AOA and retreating blade has increased AOA leading to forward facing thrust

52
Q

Translating Tendency

A

Tail rotor thrust used to counteract torque effect pushes the helicopter to the right counteracted by left cyclic

53
Q

Transverse flow

A

10-20 kts front half or disk operates in more horizontal flow of air and increases lift

Rear portion of disk operates in a higher induced flow caused by the amount of time the disk has to operate on air passing over it

Difference in lift between fore and aft portions of disk cause unequal drag and vibration

Effects manifest in 90 degrees in rotation

54
Q

Effective translational lift

A

16-24 kts Blades outrun their own downwash and operate in relatively undisturbed air.

-Increased efficiency, increased rate of climb and performance

55
Q

Settling with power

A

Helicopter settles in own downwash, vortex ring state forms vortices at blade tips

-Condition:
1)Descent >300 ft/min
2)Low airspeed < ETL
3)20-100% power to rotor with insufficient power to arrest descent

-Conducive Conditions
1)Steep approach at high rate of descent
2)Downwind approach
3)Formation flight approach
4)Hover above max. hover ceiling
5)OGE hover bad altitude control
6)Masking/unmasking

56
Q

Dynamic Roll Over

A

A lateral rolling tendency that occurs on level ground, slopes, or in crosswinds

-Pivot Point, A rolling motion, Exceeds critical angle

-Human Factors (IIIFL)
1)Inattention
2)Inexperience
3)Inappropriate control inputs
4)Failure to take timely corrective actions
5)Loss of visual reference
