ANSWERS
3 |types |of |bearings |commonly |found |in |engines? |- |CORRECT |ANSWER✔✔-plain, |ball, |roller
3 |types |of |major |propeller |shafts? |- |CORRECT |ANSWER✔✔-tapered, |splined, |flanged
1. |_______, |the |first |and |most |important |requirnment |for |an |AC |engine |is |that |it |must |be |
2.________. |At |the |end |of |WWI, |the |Curtis |OX-5 |regularly |failed |after |only |30 |hours |of |
operation. |During |the |1950s, |airlines |often |ran |Wright |R-3350s |3000 |hours |- |CORRECT |
ANSWER✔✔-1. |reliability |2. |realiable
Perhaps |the |greatest |engine |related |airframe |advance |was |the |development |of |the |______ |
cowl, |which |reduced |the |cooling |drag |of |air |cooled |radial |engines |so |levels |that |were |
competitive |with |liquid-cooled |engines. |- |CORRECT |ANSWER✔✔-NACA
In |regards |to |the |engine |arrangement |of |cylinders, |any |engine |flexes |as |it |runs |and |must |be |
stiff |enough |so |that |it |does |not |crack |its |components. |This |required |a |very |heavy |crankshaft. |
The |______ |configuration |avoids |this |problem |by |having |a |short |stiff |crankcase |and |crankshaft.
|- |CORRECT |ANSWER✔✔-radial
The |greatest |_______- |advance |was |the |introduction |in |the |1930s |of |controllable |pitch |and |
later |automatically |controlled |constant |speed. |- |CORRECT |ANSWER✔✔-propeller
by |______, |AC |piston |engines |had |reached |their |pinnacle |of |development. |They |had |become |
light, |powerful, |realiable, |and |fuel |efficient. |- |CORRECT |ANSWER✔✔-1950
Define |flashpoint |- |CORRECT |ANSWER✔✔-Shows |the |temp |at |which |a |liquid |will |begin |to |give |
off |ignitable |vapors. |Sufficient |amount |of |vapors |to |support |a |flame.
