Abstract: A gas turbine engine includes a shaft defining an axis of rotation. An outer rotor directly drives the shaft and includes an outer set of blades. An inner rotor has an inner set of blades interspersed with the outer set of blades. The inner rotor is configured to rotate in an opposite direction about the axis of rotation from the outer rotor. A gear system couples the inner rotor to the shaft and is configured to rotate the inner set of blades at a faster speed than the outer set of blades.

An outer rotor has an outer set of blades interspersed with the inner set of blades. The outer rotor is configured to rotate in an opposite direction about the axis of rotation from the inner rotor. A gear system couples the outer rotor to the shaft and is configured to rotate the inner set of blades at a lower speed than the outer set of blades.

Abstract: A compressor section includes a counter rotating low pressure compressor that includes outer and inner compressor blades interspersed with one another and are configured to rotate in an opposite direction than one another about an axis of rotation. A transmission couples at least one of the outer and inner compressor blades to a shaft. A turbine section includes a counter rotating low pressure turbine having an outer rotor that includes an outer set of turbine blades. An inner rotor has an inner set of turbine blades interspersed with the outer set of turbine blades. The outer rotor is configured to rotate in an opposite direction about the axis of rotation from the inner rotor. A gear system couples at least one of the outer and inner rotors to the shaft.

Abstract: Motor de turbina a gás. É descrita uma seção do compressor que inclui um compressor de baixa pressão contrarrotativo que inclui pás do compressor externas e internas entremeadas umas com as outras e que são configuradas para girar em uma direção oposta umas às outras em torno de um eixo geométrico de rotação. Uma transmissão acopla pelo menos uma das pás do compressor externo e interno em um eixo. Uma seção da turbina inclui uma segunda turbina de baixa pressão contrarrotativa com um rotor externo que inclui um conjunto externo de pás de turbina. Um rotor interno tem um conjunto interno de pás de turbina entremeado com o conjunto externo de pás de turbina. O rotor externo é configurado para girar em uma direção oposta em torno do eixo geométrico de rotação em relação ao rotor interno. Um sistema de engrenagem acopla menos um dos rotores externo e interno no eixo
