Seventeen Gulfstreams with recently overhauled Rolls-Royce Spey or Tay engines were grounded last month when a problem was discovered with the engines’ air control actuator (ACA), a key fuel control component. All the engines were being, or had recently been, overhauled by either Rolls-Royce or BizJet International. According to Gulfstream, three of the aircraft were already in scheduled maintenance at the time.
Rolls-Royce and Chinese aerospace representatives have signed a “collaborative agreement” to study a new regional jet application for the Rolls-Royce BR710 engine. An MOU, signed by representatives of Rolls-Royce Deutschland and the China Aviation Industry Corporation (AVIC), involves the potential use of the 14,000 lb- to 17,000-lb-thrust BR710 on China’s proposed ARJ21 regional jet.
The story of how a 100-year-old prestige motor car company evolved into one of the world’s premier aircraft engine manufacturers is rooted in the weaving together of two fundamental principles–adaptability and commonality.
Despite the large-cabin Gulfstream’s aura of being the all-American business jet, it
has significant European content. On the G350/450 that content includes the pair of Rolls-Royce Tay engines, and on the G500/550 it includes not only the Rolls-Royce Deutschland BR710 turbofans but also the tail, which is made by Stork Fokker in Holland.
Parker Aerospace companies are supplying a wide range of systems and components to airframes that range from the Airbus A380 and Boeing 787 airliners to the unmanned combat aircraft, including the first inert gas generating system (IGGS) for an Airbus aircraft.
