JET ENGINES

JET  ENGINES  ARE  USED  BY   MOST  MILITARY  and   heavy  aircraft, and  by   many  Helicopters.The   simplest  type  of  jet  engine  or  gas turbine  is   the  turbojet.It    work  by  continuous  burning   a  mixture   of  fuel  and  air   in  a  combustion   chamber  to  produce  a  jet  of  hot  exhaust    gas,   that  is   expelled  through   a  nozzle    to  produce  a thrust.The  hot  gas  also  spins   the  turbine  blades,which  ,in  turn spin,  the  blades   of  an   air   compressor,the  compressor  forces   air   into  the  combustion    chamber.Many  of  th


e  fastest   aircraft   use  turbojet  with  additional  booster   units  called  afterburners ,but  their  use  is    restricted   by  their  noise  emission  ,Most  jetliners  use  turbofan  jet  engines ,which  are  quieter  .An     enormous  fan ,driven  by  a  low  -pressure  turbine,feed  some  air  into   the  compressor  but  feeds  most  of  it  through   bypass  ducts  to  join  the  exhaust  jet stream  in  the  tail cone.The  bypass stream  produces  most  of  the thrust.Many  smaller  ,propeller driven   aircraft   use  turboprop   jet engines , in  which   engine  powers  a  propeller .
