Chinese Hypersonic Developments (HGVs/HCMs)

Shouldn’t this be a post for radars and not hypersonic?

I thought about this as well, but it's not exactly radar either. There are so many components involved with this multi-layered system, including infrared detection, that I thought radar thread might not be appropriate. Since this is an exclusively anti-hypersonic system, I thought maybe this thread is the place to put it, even if the fit is not ideal.

Maybe mods could move this where they see fit.

I think it's fine here, as a system I think hypersonic defense systems are more relevant in a hypersonic thread for now (and likely for the next few years) rather than the generic radar thread.

This is related and relevant. Excerpts from a study on a multi-layered early warning system against (trans-Pacific) hypersonic vehicles. My technical Chinese is limited, so someone please help with a translation. From what I understand, a multitude of satellites in different orbits will work in concert with ground stations and low-altitude detectors to provide early warning using a variety of radar and electro-optical detection systems.

An illustration taken from a study on a conceptual hypersonic aircraft. The illustration shows the lift requirement for the various flight altitudes. The conceptual aircraft is in the 30-ton class and capable of Mach 6 and cruising/flying at an altitude well above 20km.

A patent from Chengdu Aircraft Design Institute (611) on applying heat-resistant "marking" paint on a hypersonic military aircraft and/or space plane that is capable of reaching Mach 5 - Mach 25. The patent is in English at Google Patents (first link below).

A hypersonic concept that utilizes vortex waves(?). I have no idea what it means, but just posting it here for the record.

This is pretty big news. The 31st Institute of CASIC has successfully completed initial testing of the pre-cooler for a combined-cycle engine, with the results exceeding all expectations. This combined-cycle engine is code named Cloud Dragon (云龙), but I'm not sure if it's RBCC, TBCC, or TRCC. Another milestone toward a single-stage spaceplane.

Holyshit, that's huge news.
China does have its own SABRE engine project, so maybe it's for that?

Combined-CyCle ConCeptsHighlighted presentations at Xia-men on missions and vehicles in-cluded an integrated design method for an adaptable hypersonic dual wa-verider with twin scramjets fed by two 3D inward-turning inlets. The paper, from researchers at Avic, indicated the sharply swept delta-winged de-sign with bifurcated inlets would have “satisfactory” performance at diferent angles of attack across a speed range of Mach 4-6.A second highlighted vehicles study, presented by Yuan Yu of the Beijing-based China Academy of Launch Ve-hicle Technology, evaluated a recon-fgurable waverider that would unfold its wings following deployment from beneath the shroud of a launch vehi-cle. While the details of the application were not discussed, the study appears to be clearly aimed at increasing the potential size—and therefore capa-bility—of hypersonic glide vehicles that could be boosted into the upper atmosphere by intermediate or large ballistic missiles.The papers also reveal a major Chi-nese focus on advanced combined-cy-cle propulsion systems for two-stage orbital vehicles, including precooling hypersonic air-breathing engines as well as a variety of turbine-based com-bined-cycle (TBCC) and rocket-based combined-cycle engines. Researchers from the Beijing Institute of Aerospace Technology also provided one of the most startling revelations of the con-ference, of significant progress on a hybrid engine dubbed the turbo-aided rocket-augmented ramjet (TRRE) combined-cycle engine (see page 55).Under testing and development for more than two years by the Beijing Power Machinery Research Institute, the TRRE is designed to operate from a standing start to Mach 6+ and from sea level to 33-km altitude. The propul-sion system combines a turbine engine, rocket and ramjet with a common, adaptable inlet and exhaust and is in the frst of three planned development phases. Developers plan to conduct the frst tests of the prototype engine up to Mach 6 in a free-jet facility later this year. Initial fight tests of a TRRE subscale demonstrator are planned by HypersoniCsTests of a magneto-hydrodynamic heat shield system showed performance could be boosted by seeding the fow with potassium particles.college of aerospace scieNce aND eNgiNeeriNg and full-scale envelope expansion by 2030.
