“萨菲尔”（Sapphire）和“梅特罗维克”（Metrovick）F9飞机的研制工作一起于l946年开始，当梅特罗波里顿-维克斯（Metropolitan-Vickers）于1947年从航空界退出后转交给阿姆斯特朗-西德利公司。“萨菲尓”发动机于1948年10月首次运转，先后在“彗星（Meteor）、“哈斯汀斯”（Hastings）和“堪培拉”（Canberra）飞机上作过飞行试验，然后投入批生产，用于格洛斯特公司的“标枪”（Gloster Javelin）和霍克公司的“猎人”（Hawker Hunter)F2飞机。
The Sapphire originated in 1946 with the Metrovick F9, which was handed over to Armstrong-Siddeley when Metropolitan-Vickers withdrew from aviation in 1947. The Sapphire first ran in October 1948 and the engine was flight tested in Meteor, Hastings and Canberra aircraft; before going into production for the Gloster Javelin and Hawker Hunter F2.

4．燃气涡轮发动机的控制通常要求只用一根操纵杆并且监视位于驾驶员仪表板(图12-1)上的某些指示器。用操纵杆(油门／功率)选择某个推力水平之后，这个推力水平就由燃油系统(第l0章)自动保持。

5．对于装有加力燃烧室的发动机，仍保持使用一根操纵杆的控制，但是需用另一个燃油系统来供应及控制给加力燃烧室的燃油。
6．对于涡轮螺桨发动机，油门杆和螺旋桨控制装置是联动的，因而保持用一根杆操纵发动机。同样，直升机的油门控制杆与总距操纵杆是联动的，所以能保证桨距增加时同时增大发动机功率。

5. On engines fitted with afterburning, single lever control is maintained, although a further fuel system is required to supply and control the fuel to the afterburner (Part 16). 仪表板
6.
On a turbo-propeller engine, the throttle lever is interconnected with the propeller control unit (P.C.U.), thus maintaining single lever operation of the engine. Similarly, the throttle control lever of a helicopter is interconnected with the collective pitch lever, so ensuring that an increase in pitch is accompanied by an increase in engine power,
7.
The fuel system (Part 10) incorporates a high pressure fuel shut-off cock to provide a means of stopping the engine. This may be operated by a separate lever, interconnected with the throttle lever, or electrically actuated and controlled by a switch on the pilot's instrument panel.
8.
A turbo-jet engine fitted with a thrust reverser usually has an additional control lever that allows reverse thrust to be selected (Part 15). On a turbo-propeller engine, a separate control lever is not required because the interconnected throttle and
