RUCKER FLIGHT SCHOOL EXAM
QUESTIONS AND ANSWERS
Rotor blade coning is a compromise between which two forces? - ANSWER-
centrifugal force and lift
Define gyroscopic precession - ANSWER-When a force is applied to a rotating body,
it will manifest 90 degrees after application in the direction of rotation
why is rotor twisting necessary - ANSWER-to distribute the lifting force more evenly
along the blade
four methods to overcome translating tendency - ANSWER--rigging cyclic
-tilting mast
- left cyclic
- SAS/AFC
Four rotor blade actions - ANSWER-Rotation, Flapping, Feathering, Hunting
what are the two components of total force - ANSWER-lift and thrust
describe the relationship between total force to the tip path plane - ANSWER-
perpendicular
define effective translational lift - ANSWER-when the rotor completely outruns the
recirculation of old vortices and begins to work in relatively undisturbed air
ETL airspeed - ANSWER-16-24 KTS
TFE transverse flow effect airspeed - ANSWER-10-20 KTS
Define settling with power - ANSWER-A condition of powered flight in which the
helicopter settles in its own downwash.
three simultaneous conditions required for settling with power - ANSWER-vertical
descent of at least 300 FPM, engine must be using at least 20-100 percent, adjust
airspeed less then ETL
List the required recovery procedures for settling with power - ANSWER-increase
airspeed w? cyclic, reduce collective as altitude permits
Define auto rotation - ANSWER-flight condition during which no engine power
supplies and main rotor driven by relative wind
how does a pilot prevent a rotor RPM over sped during autorotation with turn? -
ANSWER-pilot must prevent rotor RPM overspeed with collective control
