Chinese space transportation company Lingkong Tianxing Technology (Space Transportation)It can operate at almost twice the altitude of commercial airliners and reach twice the speed of Concorde. JinDou400 named (JinDouyun) ramjet detonation engine (ramjet detonation engine) tested successfully.

Motor, 65.000 ftof (19,812 m) Mach 4 It is aimed to fly at a speed of (5,000 km/h). Yunxing supersonic passenger plane will form your heart.

Conventional ramjet engines operate by relying on the speed of the aircraft to get air into the engine and compress it. This compressed air mixes with fuel and ignites, producing thrust. The engine has a very simple structure There are no moving parts such as turbines or compressors.

Advantages of ramjet detonation engine

However, instead of a steady and steady flame, JinDou400 explosive (detonation) combustion is using. In the combustion chamber, it is much more powerful and efficient than normal combustion. controlled explosions are created and the engine Produce more thrust with less fuelIt enables it to work effectively. However, this is only possible at much higher speeds.

The company has not made public the exact dimensions of the JinDou400 engine, but reports say the engine is approximately 3 m long and about 30 cm in diameter He says it is. JinDou400, which is quite remarkable for a motor of this size. 400 kgf thrust can produce.

Ramjet engines do not use moving parts such as compressors and turbine components found in conventional turbojets. In addition to being compact, lightweight, efficient, they can be produced at a lower cost. Their disadvantage is that they are completely ineffective at low speeds. Therefore, they are used in conjunction with turbojets so that the aircraft can fly in subsonic flights.

First flight with full-size prototype is targeted in 2027

Chinese SCMP news site reported that the Yunxing prototype aircraft successfully flew at Mach 4 on October 26, 2024. Space Transportation It aims to prepare a full-size supersonic passenger jet for its first flight in 2027.

Yunxing supersonic aircraft, produced by the USA in 1966, with hybrid turbojet/ramjet-shod engine. SR-71 BlackbirdIt looks quite similar to . Blackbird could reach speeds of Mach 3.3 (3,529 km/h) at an altitude of 85,069 ft (25,929 m). The strategic reconnaissance aircraft was retired in 1999.

Yunxing promises to be significantly faster than the SR-71, using JinDouyun ramjet burst engines. Yunxing also vertical landing and takeoff will also have the ability to do so.
