“薩菲爾”（Sapphire）和“梅特羅維克”（Metrovick）F9飛機的研制工作一起于l946年開始，當梅特羅波里頓-維克斯（Metropolitan-Vickers）于1947年從航空界退出后轉交給阿姆斯特朗-西德利公司。“薩菲尓”發動機于1948年10月首次運轉，先后在“彗星（Meteor）、“哈斯汀斯”（Hastings）和“堪培拉”（Canberra）飛機上作過飛行試驗，然后投入批生產，用于格洛斯特公司的“標槍”（Gloster Javelin）和霍克公司的“獵人”（Hawker Hunter)F2飛機。

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．燃氣渦輪發動機的控制通常要求只用一根操縱桿并且監視位于駕駛員儀表板(圖12-1)上的某些指示器。用操縱桿(油門／功率)選擇某個推力水平之后，這個推力水平就由燃油系統(第l0章)自動保持。

5．對于裝有加力燃燒室的發動機，仍保持使用一根操縱桿的控制，但是需用另一個燃油系統來供應及控制給加力燃燒室的燃油。
 
6．對于渦輪螺槳發動機，油門桿和螺旋槳控制裝置是聯動的，因而保持用一根桿操縱發動機。同樣，直升機的油門控制桿與總距操縱桿是聯動的，所以能保證槳距增加時同時增大發動機功率。

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). 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
