increase |or |decreasing |the |amount |of |lift |produced |by |the |rotor.
, Describe |the |function |of |a |rotorcraft |cyclic |pitch |control. |- |CORRECT |ANSWER✔✔-The |cyclic |
control |tilts |the |main |rotor |disc |by |by |changing |the |pitch |angle |of |each |rotor |blade |during |its |
cycle |of |rotation, |which |causes |the |helicopter |to |move |in |the |direction |the |rotor |tilts.
What |mechanism |is |most |commonly |used |to |compensate |for |the |torque |produced |by |the |
main |rotor |of |a |helicopter? |- |CORRECT |ANSWER✔✔-The |tail |(or |anti-torque) |rotor.
How |is |the |amont |of |thrust |produced |by |the |tail |rotor |controled? |- |CORRECT |ANSWER✔✔-By |
moving |the |foot |pedals
Why |should |control |surfaces |be |locked |when |an |aircraft |is |parked? |- |CORRECT |ANSWER✔✔-To
|prevent |damage |from |the |wind.
What |is |the |major |damage |to |aluminum |structures |that |is |caused |by |exposure |to |the |
weather? |- |CORRECT |ANSWER✔✔-Corrosion.
Name |several |methods |for |forming |sheet |metal |- |CORRECT |ANSWER✔✔-Bending |or |folding, |
streching, |shrinking, |bumping, |and |crimping.
