Le risque de panne attribuable à la défaillance des aubes de compresseur des hélicoptères à turbine, comme celle survenue dans l’incident en cause, sera réduit si l’on prend les précautions nécessaires au niveau de la conception, de la maintenance et des opérations pour faire en sorte que l’air qui pénètre dans l’entrée d’air du moteur est exempt le plus possible de tous contaminants solides, et ce, dans toutes les conditions d’exploitation. 1, record 1, French, - d%C3%A9faillance%20des%20aubes%20de%20compresseur

Success of vortex theories in the performance analysis of horizontal axis wind turbines depends greatly upon accurate specification of the geometry of the vortex wake... An earlier wake model of helicopter rotors is extended for wind turbine applications, the fast free wake method(FFW). The FFW was accomplished by partitioning the flow field downstream of the rotor into three regions :(1) the near wake, modeled as a series of straight vortex lines;(2) the intermediate wake, modeled as a number of vortex rings; and(3) the far wake, taken to be a semi-infinite cylindrical wake. 3, record 3, English, - fast%20free%20wake%20method

An arrangement in which the turbine extracts just sufficient energy from high pressure gas to drive the compressor and where the gases leaving the turbine will still be at a pressure above atmospheric and can be expanded in a propelling nozzle to produce a high velocity jet.

Record number: 7, Textual support number: 1 CONT
Gas turbine engines for aircraft come in many types and sizes, each of which has its advantages and also its limitations. The most common type is the uncomplicated turbojet, similar to the typical jet engine described earlier. Because it has no added features such as a fan, propeller, of free turbine, this kind of turbojet is sometimes referred to as straight jet engine.
