Abstract

UNIDADE AUXILIAR DE POTÊNCIA, E, MÉTODO DE REFRIGERAR SELETIVAMENTE UMA UNIDADE AUXILIAR DE POTÊNCIA. Uma APU tem um controle para controlar uma carga sobre a APU de uma aeronave associada. O controle recebe ainda informação com relação a um desafio de temperatura em torno da APU. Se o desafio de temperatura excede um limite predeterminado, então o controle opera a APU com uma carga reduzida em um ciclo de refrigeração para reduzir a carga de calor a partir da APU sobre um cone de cauda associado. Um método também é exposto.
