A resposta correta é a letra d) Todas as afirmações estão corretas. O ciclo Brayton é um ciclo termodinâmico ideal que é usado em turbinas a gás. Ele é composto por duas transformações isobáricas e duas transformações isentrópicas ou adiabáticas. A eficiência térmica do ciclo Brayton é dada pela fórmula: η = 1 - (Q2 / Q1). A variação de propulsão a jato do ciclo Brayton visa usar o trabalho realizado pela turbina para mover um veículo. Os principais equipamentos do ciclo Brayton são o compressor, a câmara de combustão, a turbina e o bocal.
