A ramjet consists essentially of

  • A.An inlet, a combustor and a nozzle with no rotating machinery
  • B.A compressor, combustor and turbine
  • C.A fan, a core and a bypass duct
  • D.A propeller and a gearbox

Answer: A

Forward speed alone supplies the compression that a turbojet obtains from its compressor. Removing the rotating machinery makes the engine mechanically simple and light, and allows flight speeds no turbojet could reach.
