New Supersonic Ramjet Engine Could Revolutionize Air Travel: Jindou400

China's New Supersonic Ramjet Engine Could Revolutionize Air Travel
China is taking a bold leap forward in aerospace innovation with the unveiling of its JinDou400 ramjet detonation engine, also known as "JinDouyun." Developed by Lingkong Tianxing Technology, this state-of-the-art engine has recently completed a groundbreaking test, reaching speeds of Mach 4 (3,106 mph / 5,000 km/h) at an altitude of 65,000 feet—nearly twice the height of commercial airliners. With this achievement, China is setting the stage for the next era of supersonic travel.

Unlike traditional ramjets, the JinDou400 utilizes detonation combustion, harnessing controlled explosions to deliver unmatched thrust and efficiency at high speeds. Measuring just 10 feet in length and a mere 12 inches in diameter, this compact powerhouse generates an impressive 882 pounds of thrust, proving that big things can come in small packages. This engine will power the upcoming Yunxing supersonic passenger jet, which promises speeds far exceeding even the legendary SR-71 Blackbird.

But the Yunxing isn’t just fast—it’s revolutionary. Featuring vertical take-off and landing (VTOL) capabilities, it redefines versatility in aviation, catering to both civilian and military applications. Space Transportation plans the Yunxing’s maiden flight for 2027, marking a historic moment in aerospace technology.

Meanwhile, other global players like Astro Mechanica and Boom Supersonic are racing to keep up with innovative solutions in high-speed and sustainable aviation. But can they match the ambition and pace of China's aerospace advancements?

In this video, we’ll break down the JinDou400’s cutting-edge features, how it compares to traditional engines, and its potential impact on global air travel. Don’t miss this deep dive into the future of supersonic flight!
