'''YF-1'''是一款由中华人民共和国研制、生产的[[燃气发生器循环]]液体火箭发动机，使用[[四氧化二氮]]和[[偏二甲肼]]作为燃料。这是一款基本发动机，当被安装在四发动机模块中时组成'''YF-2'''，同时也以此为基础研制出高空版本'''YF-3'''。<ref name=b14643-cz1prop /><ref name=mowthorpe-tmawos />

有人认为它是直接仿制{{Link-en|Isaev|Aleksei Isaev}} {{Link-en|OKB-2|A.M. Isayev Chemical Engineering Design Bureau}}（{{Link-en|NII-88|TsNIIMash}}）开发的С.2.1100/С.2.1150 {{Link-en|La-350|Burya}}助推发动机而来。<ref name=sd-df3/>众所周知，火箭发动机的开发在燃烧不稳定方面会面临困难，需要很长时间才能实现可靠的燃烧。

== 版本 ==
该基础发动机从[[东风-3中程弹道导弹|东风-3]]开始使用，一直是[[长征一号系列火箭|长征一号]]运载火箭的主要推力。<ref name=b14643-cz1prop />

* '''YF-1'''：芯级发动机。最初用于东风三号上飞行。使用偏二甲肼/[[赤煙硝酸|AK27S]]作为推进剂。据称是仿制自OKB-2的С.2.1150。<ref name=b14643-df3 /><ref name=sd-df3 />
* '''YF-1A'''：芯级发动机。改进后用于东风-3A 、 [[东风-4远程弹道导弹|东风-4]]和长征一号。<ref name=b14643-df3 /><ref name=b14643-cz1prop /><ref name=sd-df3 /><ref name=sd-df4 />
* '''YF-1B'''：芯级发动机。改进后用于[[長征一號丁運載火箭|长征一号丁]]。将推进剂更改为偏二甲肼/四氧化二氮。<ref name=b14643-cz1prop />
* '''YF-3'''：上面级发动机。用于[[东风-4远程弹道导弹|东风-4]]。<ref name=b14643-cz1prop />
* '''YF-3A'''：上面级发动机。改进后用于[[長征一號運載火箭|长征一号]]。<ref name=b14643-cz1prop />

== 模块 ==
虽然YF-1作为单个发动机也被多次使用，但它仅作为单个发动机用于助推器。通常会捆绑多台发动机作为模块使用。

用于第一级的相关模块：

* '''YF-2'''：包含四台YF-1的模块。最初用于[[东风-3中程弹道导弹|东风-3]]。<ref name=b14643-df3 />
* '''YF-2A'''：一个包含四台YF-1A的模块。改良版。用于[[东风-3中程弹道导弹|东风-3A]] 、 [[东风-4远程弹道导弹|东风-4]]和[[長征一號運載火箭|长征一号]]。<ref name=b14643-df3 /><ref name=b14643-cz1prop />
* '''YF-2B'''：一个包含四台YF-1B的模块。改良版。[[長征一號丁運載火箭|长征一号丁]]上使用的最终版本。<ref name=b14643-cz1prop />
