text: Of course, the combustion chamber discharge 
  could be more completely expanded through a 
  larger turbine section and the net power could 
  be used to operate a propeller rather than pro- 
  vide high exhaust gas velocity. For certain 
  applications, the gas turbine-propeller combi- 
  nation could utilize the high power capability 
  of the gas turbine with greater propulsive 
  efficiency. 
  
  FUNCTION OF THE COMPONENTS. 
  Each of the engine components previously de- 
  scribed will contribute some function affecting 
  the efficiency and output of the turbojet engine. 
  these components 
  For 
  should be analyzed to determine the requite- 
  ments for satisfactory operating characteristics. 
  The i&t or &@er must be matched to the 
  powerplant to provide the compressor entry 
  with 
  the 
  the required airflow. Generally, 
  compressor inlet must receive the required air- 
  flow at subsonic velocity with uniform dis- 
  tribution of velocity and direction at 
  the 
  compressor face. The diffuser must capture 
  high energy air and deliver it at low Mach 
  to the compressor. When 
  number uniformly 
  the inlet is along the sides of the fuselage, the 
  edges of the inlet must be located such that 
  the inlet receives only high energy air and 
  provision must be made to dispose of the
