中国正在寻求小型涡扇发动机技术和涡轮喷气发动机，当做动力选项用于远程巡航导弹。以前，中国远程巡航导弹已经采用涡轮喷气技术，在HY-4（C-401）和YJ-82（C-802）设计中，导弹弹体最初为火箭动力设计。

    中国据报导已经发展小型涡扇发动机超过十年。已有对中国小型涡扇发动机技术来源的推测，长期持续未经证实的传闻认为在1990年中国引进苏联设计的Kh-55 SE（AS-15 'KENT'），连同美国巡航导弹残骸。在2005年早期，中国据传闻已经从乌克兰接收了六枚Kh-55 SE导弹。

China develops small turbofans

By David C Isby

    China is pursuing small turbofan technology as well as turbojets as power options for long-range cruise missiles. Previously, Chinese long-range cruise missiles have used turbojet technology, as in the HY-4 (C-401) and YJ-82 (C-802) designs, in airframes originally intended for rocket power.

    China has been reported to be developing small turbofans for more than a decade. There has been speculation as to the source of Chinese small turbofan technologies. Long-standing unconfirmed reports suggest that Soviet-designed Kh-55SEs (AS-15 'Kent') were imported in the 1990s, along with US cruise missile wrecks. In early 2005, China was reported to have received six Kh-55SE missiles from Ukraine.
