“薩菲爾”（Sapphire）和“梅特羅維克”（Metrovick）F9飛機(jī)的研制工作一起于l946年開(kāi)始，當(dāng)梅特羅波里頓-維克斯（Metropolitan-Vickers）于1947年從航空界退出后轉(zhuǎn)交給阿姆斯特朗-西德利公司。“薩菲尓”發(fā)動(dòng)機(jī)于1948年10月首次運(yùn)轉(zhuǎn)，先后在“彗星（Meteor）、“哈斯汀斯”（Hastings）和“堪培拉”（Canberra）飛機(jī)上作過(guò)飛行試驗(yàn)，然后投入批生產(chǎn)，用于格洛斯特公司的“標(biāo)槍”（Gloster Javelin）和霍克公司的“獵人”（Hawker Hunter)F2飛機(jī)。

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.

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). 儀表板

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
