Reseña: Construction and strength of aircraft part 1. Construction and strength of main components of gas turbine engines

 The overwhelming majority of contemporary aircraft engines are heat engines. A heat engine is a machine, which converts heat energy into mechanical work. Any heat engine consists of:

  • A combustion chamber (combustor) where chemical energy, which is contained in fuel, converts, to heat energy;
  • A device, which converts heat energy to mechanical work (sometimes a heat engine has several similar devices and energy is transformed in various stages of steps);
  • A propulsive device (propulsor), which directly realizes the motion of the aircraft.
