Evolução dos aviões: entenda as mudanças ao longo da história
Em 1914, um voo de 23 minutos que levava apenas um passageiro criou a aviação comercial. Mais de cem anos depois vemos que esse setor é um dos ...
GE90-115B
Esse é basicamente o princípio dos motores à reação utilizados em aeronaves a jato da atualidade. Obviamente, a tecnologia evoluiu muito desde aquele tempo. O maior motor à reação é o <anchor>GE90-115B</anchor>, da General Electric, que equipa as asas do Boeing 777. Motores como esse são capazes de sugar mais de 2 milhões de pés cúbicos de ar por minuto e custam cerca de 24 milhões de dólares.

GE90-94B Engine

##### GE90-94B engine

Rated at 94,000 lbs. of thrust, the GE90-94B engine builds on the proven success of the early GE90 engine models to power the Boeing 777-200 and 777-300 aircraft.

GE90-115B Engine

##### GE90-115B engine

After being selected by Boeing to develop an engine with 110,000 to 115,000 lbs. of thrust, GE Aerospace delivered the GE90-115B engine, which now powers the longer-range Boeing 777-200LR, 777-300ER, and 777 Freighter aircraft.
