What is the positioning and interconnect of the engine and transmission on the Bell 47 helicopter disused?

• The engine is mounted horizontally with the transmission attached directly to and driven by the output end of the engine

• The engine is mounted vertically with the transmission attached directly to and driven by the output end of the engine

• The engine is mounted horizontally below the transmission and linked to the transmission drive using drive belts

• The engine is mounted horizontally below the transmission and linked to the transmission drive using drive belts

What is the positioning and interconnect of the engine and transmission on the Robinson R22 helicopter disused ?

• The engine is mounted on an angle in the nose of the aircraft and inked to the transmission located behind and above the pilots with a shaft running from the engine to the transmission between the pilots

• The engine is mounted vertically with the transmission attached directly to and driven by the output end of the engine

• The engine is mounted horizontally below the transmission adn linked to the transmission drive using drive belts

• The engine is mounted vertically beside the transmission and linked to the transmission drive using drive belts

What is the positioning and interconnect of the engine and transmission on the Sikorsky S-578 helicopter disused?

• The engine is mounted on an angle in the nose of the aircraft and inked to the transmission located behind and above the pilots with a shaft running from the engine to the transmission between the pilots

• The engine is mounted vertically with the transmission attached directly to and driven by the output end of the engine

• The engine is mounted horizontally below the transmission and linked to the transmission drive using drive belts

• The engine is mounted vertically beside the transmission and linked to the transmission drive using drive belts

Why does the Aerospatiale Aloutte or Gazelle require some form of centrifugal clutch in order to aid the starting process?

• The starter motor drives a flywheel that engages through a centrifugal clutch to the engine. Once it reaches a certain speed to turn the engine

• The centrifugal clutch disconnects the engine from the transmission and rotor system during the start sequence due to the fixed or single shaft turboshaft engine design

• The centrifugal clutch disconnects the engien from the transmission and rotor system during the start sequence due to the free power turbine turboshaft engine design

• The centrifugal clutch disconnects the engine from the transmission and rotor system during the start sequence due to the radial type piston engine installed
