ABSTRACT:
A turbine engine arrangement is provided in which contra rotating shafts104, 105are respectively secured to a fan and a gearbox106which is also coupled to the shaft104. In such circumstances the relative rotational speed ratio between the shafts104, 105can be determined with a first low pressure turbine101secured to the first shaft104arranged to rotate at a lower speed but provide high work whilst a second low pressure turbine102secured to the second shaft105rotates at a higher speed governed by the gearbox106. By such an arrangement a smaller gearbox106may be used as less power is transferred through that gearbox106than with previous arrangements. By contra rotation of the turbines101, 102a lower flow deflection guide vane assembly103may be used and a further stator/guide vane assembly is not required between the turbines101, 102.
