Explainer: Buoyancy‑engine Integrated Intelligent Airship
A deep dive.
First, a big thank you to China-based Harald Buchmann. His comment about the buoyancy‑engine airship – specifically about the team behind it and the export claim drove me to track down the answers.
His input served as the obsession catalyst for the research presented here.
Harald is a travel operator and analyst. He runs tours to China, produces videos about the country, and regularly shares his impressions and insights on Chinese society, technology, politics, and travel – particularly for an audience of prospective visitors.
Second, thank you to all my readers. I absolutely encourage questions.
Much of the current discourse on the low‑altitude economy adopts a Western/Euro‑centric framework, which often obscures rather than clarifies China's actual developments.
Disinformation compounds the issue.
Questions are necessary.
For me, questions compel a obsessive methodical, unyielding search for verifiable facts – and this is especially important given the rise of LLM models that scrape content, including my own articles.
Recent cases in point —
My article — Chinese Start-up Offers Ultralight Personal eVTOL Aircraft
Plagiarism (published three days after mine) —YiVTOL S-ZERO Personal eVTOL: What You Need to Know
My article — Southeast Asia’s Business Aviation Sector on the Rise
Plagarism (word-for-word rip) — Avi-Go Deep Dive: Southeast Asia’s Business Aviation Sector Poised for Growth Amid Rising Wealth and Regional Demand (Avi-Go is a so-called market intelligence platform based in Singapore).
Beyond blatant plagiarism, LLM models often veer off into hype tangents and hallucinations.
Which is why human writers and researchers remain indispensable for verification.
This article answers Harald’s comment —
“Reading you piece about the Buoyancy-Engine I was confused about their claim to have delivered prototype to AVIC and exported a full airship, as well as extensive testing and high altitude flight, yet all images seem digital renderings, also on their Douyin account.”
Before we get into it…
Thank you to my paid subscribers.
This newsletter is completely independent and managed completely by me; China eVTOL News does not rely on advertising revenue.
Your support truly makes this possible.
I do the work because accurate information matters.
Or, in the words of Sigurður Hjartarson, whose contributions to the Icelandic Phallological Museum in Reykjavík are, shall we say, rather unique — "Someone had to do it."
For any company reading — I function as your personal researcher, without the overhead of a salary.
If you are using this work commercially — meaning you are financially benefiting from it because you are actively applying the research — I simply ask that you subscribe to the appropriate tier (the highest tier, which is extremely affordable for a yearly personal researcher), unless we have come to an alternative arrangement.
I understand that aviation and consulting are fiercely competitive — even cutthroat at times.
With that in mind, I respectfully ask that my work not be used for financial gain without fair compensation in return.
Thank you to those subscribers who already do that.
And for those who require thoroughly researched, data‑driven reports on China’s low‑altitude economy or related sectors, I offer custom research services. Please reach out.
The below report took a solid 8 hours of research. Let’s get into it.
On June 13, 2025, the Civil Aviation Administration of China (CAAC) issued the advisory circulars "Type Certification for Normal and Commuter Airships" and "Type Certification for Transport Category Airships," clearing obstacles for the entire series of airship airworthiness certification.
Just over a week later, on June 21, 2025, the CAAC issued the letter "Air Tours and Experience Flights with Pilot," which explicitly stated "trial approval for the use of airships to implement long‑distance air sightseeing flights" and that "aircraft for out‑of‑town short‑distance sightseeing shall be airplanes, helicopters, and airships."
