Source-derived summary

The YF-102 is a Chinese liquid rocket engine burning LOX and kerosene in a gas generator cycle. It is manufactured by the AALPT based on the experience of previous kerolox engines, and using 3D printing technology and is capable of multiple restarts. It is used in Tianlong-2 launch vehicle developed by Space Pioneer.

History

The engine was revealed in 2021 without a target launch vehicle. In its presentation video, it was shown in a five engine configuration on a 3.35m diameter first stage and as a single engine on the second stage. As of October 2021, it was in an advanced state of development, with six fully assembled prototypes some of which had achieved over 200 seconds of test firing. It was stated that it could be ready by 2022. A reusable version, YF-102R could be ready by 2026 according to the manufacturer.

In 2023, Space Pioneer, a Chinese private aerospace startup used YF-102 engines to power its Tianlong-2 Rocket. Tianlong-2 is a medium-sized, 3-stage rocket powered by RP-1 and liquid oxygen, with a payload capability of 2 tonnes to LEO and 1.5 tonnes to SSO. The three first-stage YF-102 were arranged in a triangular arrangement.

Editorial summary

This brief starts where responsible research should: with the source description of “YF-102 (rocket engine)” as model of Chinese liquid-propellant rocket engine. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2021, 2022, 2026, 2023—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where YF-102, rocket and engine can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as model of Chinese liquid-propellant rocket engine. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q112083388. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 2022, 2026 and 2023.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
