XingKong-2 Chinese hypersonic ‘waverider’ vehicle

Chinese waverider vehicle hits Mach 6

Quote
The test of the unmanned system, designated Starry Sky 2, took place recently in Northwestern China, reports the official China Daily newspaper.

During the flight the vehicle reached an altitude of 30km and undertook several maneuvers.

The wedge-shaped vehicle was initially lifted by a solid propellant rocket, before detaching and performing its flight. China Daily reports that the aircraft is a “waverider,” using its own shock waves to generate lift.

400 seconds powered hypersonic flight is pretty remarkable for such a small vehicle. Especially one with enough of a guidance system and control surfaces for "extreme maneuvering."

I don't think this is a powered test. At least everything in the article says an unpowered waverider.
I've seen conflicting interpretations/translations and the SCMP is definitely trying to suggest powered flight, can't tell if it's just the usual PLA fanboy-ism or just people not knowing enough about what they're reporting on. I would agree that taking the possible size of the vehicle and duration cited together makes more sense as Boost-Glide.

Hmmm... Quite happy to have 'identified' this beast way back in 2016…
Several waverider patents from CAAA, NUDT (PLA), Beihang University, Univ Nanjing, Univ Xiamen
They don't play the same game and some of these actors specialized in airbreathing vehicles using Kothari-like designs…
I'll make it very being super busy those days  B)
BTW, the PLA set up a dedicated research lab/ tech center to explore hypersonic technologies called the Unit 63820. It once filled  patent on hypersonic inlet design…

Latest CAAA issued hypersonic waverider patent:

"Layout of internal and external flow waverider aircraft"
Inventor: ZHANG HONGJUN, CHEN BINGYAN
Applicant: CHINA ACAD OF AEROSPACE AERODYNAMICS CAAA   
Patent #: CN107867387 (A)
Issue date: 2018-04-03
Priority date: 2017-10-16

To the best of my knowledge, the earliest PRC recorded patent showing interest in waverider design was filed in 2008 by Nanjin univ researchers (and issued in 2010 as CN101392685).

That one on photo looks like extremely trivial solid-fuel missile with cylindrical body and conical nose. Am I missing something?

Hmmm… protective fairing released somewhere between 13 and 29km in this case?

Ah, so it's just outer cover. Found scetches with proposed visual look in one of links.

Not sure if this is the best place for this.

At the end of 2015 the missile branch of the People’s Liberation Army (PLA), the Second Artillery Force (第二炮兵部队), was formally elevated to a full service and renamed the Rocket Force (火箭军; PLARF) part of a sweeping drive to improve the PLA’s joint operations, command and control, and combat effectiveness.

The establishment of the PLARF signals the increasing importance of conventional and nuclear missiles to PLA warfighting and deterrence capabilities. It also foreshadows continued, substantial investment in missile force modernization at both tactical and strategic levels in the years ahead.
