The China Academy of Aerospace Aerodynamics has released photographs showing first guided flight test of the newest hypersonic aircraft, also called waverider.

Waverider is a hypersonic aircraft that have wedge-shaped fuselage that improves its supersonic lift-to-drag ratio by using the shock waves being generated by its own flight as a lifting surface.

According to the China Academy of Aerospace Aerodynamics, at 6:41 am on August 3, at the northwest test range was held successfully test-fired of new Star Air-2 waverider aircraft system.




The hypersonic aircraft was successfully completed active phase, jettison of aerodynamic payload fairing, autonomous and high maneuvering turning in 10 minutes’ flight.

The Aerospace Exploration Institute of the China Aerospace Science and Technology Corporation presented this waverider as the first hypersonic test aircraft in the aerodynamic layout of the wave body.

Waveriders are aircraft bodies shaped to skim along the top of the pressure wave created by their own supersonic flight — in essence, using the shock wave to increase the plane’s lift, or the upward force that keeps a plane in flight.

From video it looks like quasi ballistic missile. @The Deterrent your thoughts?
 
I don't think is the first time. The were videos circulating in the internet on objects flying rapidly across the sky.
 
No, it is not.

The "waverider" hypersonic aircraft separated from the rocket you see in the pics at an altitude of 30km and then flew in autonomous mode for over 400s reaching speeds of Mach 5.5 to 6.
It looks it will be unmanned aircraft.

A ballistic missile carry either an RV, MaRV or an HGV.

RV = Reentry Vehicle
MaRV = Maneuverable Reentry Vehicle
HGV = Hypersonic Glide Vehicle

Objective of each is same but HGV descend/glide towards its target at hypersonic speeds, faster than traditional RV and/or MaRV.

The wave rider is powered and not a glide vehicle.
 
Wave rider has a scramjet engine on it just like X-43/X-51 but hyper-sonic gilde vehcile don't have any kind of engine on it @LeGenD

That the main difference b/w HGV and wave riders @LeGenD
Did you read the paper I cited?

HYPERSONIC Glide Vehicle has been a hot topic in the aerospace area in terms of the high speed and long range performances [1]–[3]. Due to the high lift-to-drag ratio in hypersonic flow, the waverider is proved to be a remarkable basic configuration for HGV.

yes but main difference is HGV has engineless whereas wave rider has scramjet engine on it @LeGenD both have a similar in design @LeGenD
 
Superfast aircraft test a 'success'

China has successfully developed and tested a cutting-edge hypersonic aircraft that rides its own shock waves, according to the China Academy of Aerospace Aerodynamics in Beijing.

The academy, part of the State-owned space contractor China Aerospace Science and Technology Corp, announced on Friday that the first flight-test of its Starry Sky 2-which it calls the nation's first hypersonic experimental waverider vehicle-was conducted that morning at an unidentified testing field in northwestern China. It said the test was a "huge success".

A waverider is a hypersonic aircraft that has a wedge-shaped fuselage designed to improve its supersonic lift-to-drag ratio by using the shock waves generated by its own flight as a lifting force.

The hypersonic vehicle was first carried by a solid-propellant rocket and then separated as its own propulsion system took over. During the independent flight, the test craft maintained ultrafast speeds above Mach 5.5 for more than 400 seconds and reached Mach 6-7,344 kilometers per hour-according to a statement from the academy.

The United States tested an experimental waverider from 2010 to 2013 that was designed to reach Mach 6.

Tagged as the fastest aircraft ever built, the US HTV-2-which was not a waverider-achieved a record speed of Mach 20, or 24,480 km/h, during its first flight in April 2010.

The fastest manned aircraft in service is the Russian Mikoyan-Gurevich MiG-25, which boasts a maximum speed of 3,470 km/h. A Boeing 747-400ER passenger jet cruises at about 933 km/h.

In the flight-test announced on Friday, the Chinese waverider reached an altitude of 30 km and carried out large-angle maneuvers. The vehicle also tested a host of advanced technologies such as a domestically developed heat-balance thermal protection system, the statement said.

The research, sponsored by China Aerospace Science and Technology Corp, aims to demonstrate new aerodynamic technologies. It said the design of Starry Sky 2 took three years.

The test marked the first time China officially confirmed its research and development of the waverider, a futuristic concept that can be turned into a hypersonic strike weapon capable of evading all existing air-defense networks.

The US and Russia have been researching and testing waveriders for years, aiming to make use of such vehicles' potential in military applications.

Wang Yanan, editor of Aerospace Knowledge magazine, said the waverider is an ideal design for a hypersonic strike platform or ultrafast aircraft.

"The test confirms that China possesses reliable and advanced technologies for a hypersonic vehicle, as it relied on its own propulsion for a 400-second hypersonic flight-as opposed to such vehicles in other nations that didn't use their own propulsion in the first flight-test," he said.

"The test also showed that we have reached a world-class level for a hypersonic vehicle's key equipment, such as separation devices, thermal protection, flight controls and communications apparatus."

Although China had not revealed its efforts in hypersonic aircraft before Friday's test, Western media have reported that the country had designed at least one type of hypersonic craft, which Western analysts called WU-14 or DF-ZF, and that it had undergone several flight-tests.

China hails a 'successful' test of a new hypersonic weapon that could slip a nuke past US defenses

  • China claims to have successfully tested a hypersonic experimental waverider vehicle able to fly at speeds as high as Mach 6.
  • China claims the aircraft reportedly has the potential to be used as a hypersonic strike platform capable of carrying conventional and nuclear warheads and evading modern missile defense systems.
  • The US and Russia are also experimenting with hypersonic systems, but China's progress in this area has some observers on edge.
  • Additional testing of the new Chinese vehicle is expected to be carried out at an accelerated pace going forward.

China has successfully tested a new hypersonic aircraft, a potential "hypersonic strike weapon" that could one day be capable of carrying multiple nuclear warheads and evading all existing defense networks like the US missile shields, according to Chinese state-run and state-affiliated media, citing experts and the domestic designers.

The Xingkong-2 (Starry Sky-2) hypersonic experimental waverider vehicle designed by the China Academy of Aerospace Aerodynamics in Beijing can reportedly achieve a top speed six times the velocity of sound.

During the recent test, conducted last Friday at an unspecified location in northwestern China, the aircraft was first carried by a multistage solid-fueled rocket before it separated to rely on independent propulsion — it is said to have maintained speeds above Mach 5.5 for 400 seconds. The max speed was reportedly Mach 6 or 4,600 miles per hour, according to the state-run China Daily.

The wedge-shaped vehicle made several high-altitude and large-angle maneuvers at a maximum altitude of a little over 18 miles. The aircraft then landed in the targeted area as intended, with observers touting the test as a "huge success."
