Waiting for another year for a flight test?

In the meantime SpaceX is going for a 2nd landing attempt mere weeks after the failure of the first. The difference between government "efficiency" and the private sector.

Musk knows that failures will happen on occasion when you push boundaries, and he's willing to take the risk with unmanned vehicles. Most government and public-corporation projects seem to be terrified of risk, and want absolute guarantees (which anyone at the technical level knows are BS) that the item will function flawlessly from day one.

There was a video about hypersonics a while back. In it the head honcho general said they seriously considered not flying the last X-51 flight. Too scared of failure. I guess nobody told them that you don't learn how to do something by not doing it.

Navy Modifying Army-Designed Advanced Hypersonic Weapon For Land-Based 2017 Test

Posted: April 16, 2015


The Office of the Secretary of Defense has tapped the Navy to conduct the next test flight of a candidate Conventional Prompt Global Strike capability, modifying the Army-developed Advanced Hypersonic Weapon to fit in a submarine missile tube and launch the prototype weapon from a land-based test facility in 2017, according to a senior Navy official.

Vice Adm. Terry Benedict, director of Navy strategic systems programs, told InsideDefense.com during a brief April 14 interview at the Sea-Air-Space exhibition in Maryland that the service is currently working to modify the cone-shaped hypersonic glide vehicle for ship integration.

"We are currently working to take the Advanced Hypersonic Weapon shape and size it to a Navy-sized concept," Benedict said. "That is a funded program that will fly in 2017," he said.

The Pentagon's acquisition directorate for strategic warfare, sponsor of the Conventional Prompt Global Strike development effort, is effectively handing the ball to the Navy after an Army attempt to conduct a second AHW flight test last August was terminated seconds after liftoff.

In December, the Army Space and Missile Defense Command/Army Forces Strategic Command determined the cause of the failure was a blanket wrapped around the base of the booster to regulate motor temperature that got tangled in the launch steering assembly, tripping up the rocket as it lifted off.

Since 2003, the Defense Department has explored a range of options for giving commanders new ways to strike high-value, time-sensitive targets -- from terrorists to weapons of mass destruction to anti-satellite weapons -- anywhere on the planet in about an hour.

In 2008, Congress quashed a Navy proposal to fund the modification of submarine-launched Trident missiles to carry conventional weapons and perform the prompt strike mission over concern that such systems, when employed, could be misconstrued for nuclear launches. Air Force plans to develop a boost-glide hypersonic weapon stalled out after the Hypersonic Test Vehicle-2 project, pursued with the Defense Advanced Research Projects Agency, resulted in test flights in 2010 and 2011 that terminated early.

The Pentagon is seeking $72.9 million in FY-16 for a range of activities in support of the proposed FY-17 hypersonic demonstration, according to DOD's budget request. The department "completed System Requirements Review through collaboration with the national CPGS team for the next CPGS Flight Experiment 1 (FE-1) in FY 2017 using a scaled AHW glider," the budget request states.

Benedict said the new prototype weapon "will not fly off a ship, it will fly off a land-based" launcher. "It saves a lot of time and money to do the first flight off a land base," the three-star admiral added.

In September, Benedict's office awarded $10 million trade studies to both Lockheed Martin and Raytheon "to develop and evaluate technology options and concepts with application to a broad range of potential intermediate range boost-glide Conventional Prompt Global Strike architectures," according to the statement of work in the contract solicitation.

"The notional test concept is a sea-based (submarine underwater-launched) approach, which provides a challenging set of constraints and technical trade factors, but the contractor analysis of technology options shall include applicability to both the notional test concept and other potentially applicable technology options," the document states. -- Jason Sherman

A bit more detail:

Raytheon has been awarded a $20,489,714 cost-plus-fixed-fee funding for the Hypersonic Tactical Boost Glide (TBG) missile program.

The TBG program is for the development and demonstration of technologies to enable air-launched tactical range hypersonic boost glide systems. The Defense Advanced Research Projects Agency, Arlington, Virginia, is the contracting activity.

The Tactical Boost Glide (TBG) program is a Joint DARPA / Air Force effort that will develop and demonstrate technologies to enable air-launched tactical range hypersonic boost glide systems, including a flight demonstration of a vehicle that is traceable to an operationally relevant weapon that can be launched from current platforms. The program will also consider traceability to, and ideally compatibility, with the Navy Vertical Launch System (VLS). The metrics associated with this objective include total range, time of flight, payload, accuracy, and impact velocity. The program will address the system and technology issues required to enable development of a hypersonic boost glide system considering

(1) vehicle concepts possessing the required aerodynamic and aero-thermal performance, controllability and robustness for a wide operational envelope,
(2) the system attributes and subsystems required to be effective in relevant operational environments, and
(3) approaches to reducing cost and improving affordability for both the demonstration system and future operational systems. TBG capabilities are planned for transition to the Air Force and the Navy.

Hypersonic technology could be seen as a follow-on to stealth, Lewis said. Even if an aircraft has that kind of technology, it doesn’t mean it is invisible, he said. Adversaries are growing better at spotting stealthy aircraft, he said. Speed might compensate for that, he said. “If I can fly really fast, it makes it harder to act against me. It doesn’t make it impossible. But it makes it harder.”

Top Air Force leaders are indicating that they want to move hypersonic technology to the next level. Air Force Chief of Staff Gen. Mark Welsh and Secretary Deborah Lee James in the document “America’s Air Force: A Call to the Future,” said hypersonic development was number one on the service’s list of top five technology priorities. “It’s about altitude and it’s about speed,” Masiello said Sept. 16. “It’s just plain physics in terms of missiles [not] being able to intercept a cruise missile going at Mach 5-plus up at 50,000 to 60,000 feet. That gives you the survivability aspect of it.”

The Air Force has teamed with the Defense Advanced Research Projects Agency on two new hypersonic programs. There is a cruise missile called HAWC, the hypersonic air-breathing weapons concept. The other is called tactical boost glide, which will accelerate an aircraft to Mach 5 plus speeds, then let it glide to its target. “We’re going to have demonstrations within the next five years on both of those,” Masiello said. A fully reusable, combat-ready hypersonic aircraft may be in the Air Force fleet by the 2040s, he predicted. Similarly, space planes could deliver payloads in minutes. The reusable space plane concept has been proposed many times over the years, and received a new lease on life when DARPA awarded three contracts to Boeing, Masten Space Systems and Northrop Grumman to study the idea of a two-stage launch system that could rapidly place 3,000 to 5,000 pounds into orbit. The Air Force has never given up on that idea, as evidenced by the new DARPA initiative, Lewis said. DARPA experimental spaceplane (XS-1) program envisions a reusable aircraft that could be launched from a mobile platform, and return 10 times within 10 days. It would employ a reusable first stage that would fly to Mach 10 at a suborbital altitude. At that point, one or more expendable upper stages would separate and deploy a satellite into low-Earth orbit.

Australia plans mach 20 scramjet in 2018 that can fly 120 miles in 30 seconds

Australia's DSTO has been doing hypersonic experiments in Woomera, South Australia and Norway. In 2018, it plans to launch a glider with an air-breathing scramjet engine that will cruise at hypersonic speeds to travel about 200 kilometres in 30 seconds (mach 20).


“Hypersonics research is not new; it’s been conducted for 30 or 40 years. But the way the DSTO conducts its work is quite different in terms of experimentation. So we are effectively taking an IT approach. These experimentations would not be possible without IT systems. The whole payload is instrumented with IT systems,” Zelinsky said.

Sensors attached to the air-breathing engine measure the aerodynamic and thermodynamic properties in real time, which is gathered and analysed for insight into how the DSTO should shape its next experiment and to progressively advance the technology each time.
“We use telemetry, which is radio communications, a little antenna dish tracking this vehicle as this 2-stage rocket goes up into space, turns around and comes back down. We are tracking and communicating all the time and getting the megabits of data that are associated with this platform.”

The 2-stage rocket is launched into low orbital space, up to about 250-350 kilometres above the Earth’s surface. Then it’s turned to the ‘angle of attack’ and brought back down to about 20-30 kilometres above the Earth’s surface to do the hypersonic experiment.

That height above the Earth’s surface is where density of air is right to sustain hypersonic propulsion and flight without burning up. The ‘angle of attack’ means carefully aligning the vehicle to its target, because it could end up somewhere else even if it’s a few degrees out, Zelnsky said.

“When it gets to the 20-30 kilometres above the Earth’s surface, we use gravity to accelerate the vehicle to hypersonic speed. What we are doing is we are shooting the vehicle up very high up in the Earth, turning it around and then it just starts accelerating through gravity to get to that Mach 5 to Mach 10 speeds.
For a scramjet, the kinetic energy of the freestream air entering the scramjet engine is large comparable to the energy released by the reaction of the oxygen content of the air with a fuel (say hydrogen). Thus the heat released from combustion at Mach 25 is around 10% of the total enthalpy of the working fluid. Depending on the fuel, the kinetic energy of the air and the potential combustion heat release will be equal at around Mach 8. Thus the design of a scramjet engine is as much about minimizing drag as maximizing thrust.

This high speed makes the control of the flow within the combustion chamber more difficult

what the hell dose this guy talk about? a Scramjet cruise at mach 20?
 
Mach 20 cruise? That's crazy, Mach 20 gliding ended badly, I don't see how cruise works any better.

(Also, it is getting awfully close to the limit for Hydrogen thrust).

Extrapolated from a talk by the AFRL chief (or section head) scientist:

Essentially the Mach 20 flight revealed huge gaps in knowledge about hypersonic flight. It seems like they cancelled the project in order to work on the fundamental science before returning to those speeds. Here, it is notable that the Mach 10 flights seem to have no serious problems.

If we can get M10 boost glide near term (over M20 far term/never) as it beats subsonic JASSM or ALCM's any day IMHO.

I don't disagree. I just don't see how they're suppose to learn more about Mach 20 flights without testing there.

Meh. Maybe we'll have to step up to it then. Seems a crying shame though that we're at the same spot (Mach 10+) we were over half a century ago.

Surely the Mach 10 target is guided by the amount of specific impulse you can cram into a tactically sized booster that will fit in the B-2's bay.

As a broad hint, USAF can't predict heat at Mach 20, so how can they build anything for that? It was an open talk, but I don't know how much they'd like the problems broadcast around the internet.

Mach 10 may be fast enough now for a reasonable sized warhead on reasonable sized missile at a reasonable cost.

Absolutely agree we need to test and push the tech envelope my comment was more to indicate that in a time of constrained/limited budgets give me a M10 strike missile now. Of course I would also be upset that for want of a few hundred million (maybe not even that much) the US with an $18Trillion economy would even have to choose.

Or attaining Mach 20 requires a booster vehicle whose launch signature is indistinguishable from that of an ICBM which presents all sorts of strategic signaling problems.

I think that's quite a stretch. The HTV-2 wasn't a complete failure and there was controlled flight.

The problem with the HTV-2 was material limitations, which can't be fixed by flight testing. That was one of the topics from the AFRL scientist.

There's also the issue of using RANS code for hypersonic flight. That 'doesn't' work, a well known fact, but there hasn't been much progress fixing that.

China Conducts Fourth Test of Wu-14 Strike Vehicle
Posted By Bill Gertz On June 11, 2015 @ 5:00 am In National Security | No Comments

China this week carried out the fourth test of an ultra high-speed nuclear delivery vehicle that conducted what intelligence officials say were extreme maneuvers.

The test of the Wu-14 hypersonic strike vehicle was carried out Sunday, launched atop a ballistic missile fired from a test facility in western China.

It was the fourth successful test of the Wu-14 in the past 18 months and the frequency of tests is being viewed by U.S. intelligence analysts as an indicator of the high priority placed on developing the weapon by the Chinese.

Earlier tests took place last year on Jan. 9, Aug. 7, and Dec. 2. The Washington Free Beacon first reported the tests.

The new strike vehicle is considered a high-technology strategic weapon capable of delivering nuclear or conventional warheads while traveling on the edge of space. One of its key features is the ability to maneuver to avoid U.S. missile defenses.

The Wu-14 was assessed as traveling up to 10 times the speed of sound, or around 7,680 miles per hour.

Unlike earlier tests, the latest test demonstrated what one official called “extreme maneuvers” that appeared to analysts designed for penetrating through missile defense systems.

Current U.S. missile defenses are limited to knocking out missiles and their warheads with predictable ballistic trajectories that can be tracked with relative ease by satellite sensors and ground and sea radar.

However, the Wu-14 threatens to neutralize U.S. strategic missile defenses with the unique capability of flying at ultra high speeds and maneuvering to avoid detection and tracking by radar and missile defense interceptors.

The Pentagon’s Missile Defense Agency has repeatedly declined to comment on whether current U.S. missile defenses can defeat maneuvering targets.

A congressional China commission stated in a report published in November that China is working on hypersonic arms as “a core component of its next-generation precision strike capability.”

“Hypersonic glide vehicles could render existing U.S. missile defense systems less effective and potentially obsolete,” the report said.

In addition to the glide vehicle, China also is developing a second hypersonic weapon the uses a high-technology scramjet engine.

The Pentagon and China’s defense ministry confirmed the earlier tests. Asked about the latest test, however, Pentagon spokesman Lt. Col. Jeff Pool declined to comment on the test, citing a policy of not discussing intelligence matters.

However, specialists on China’s military buildup say the latest test is another significant milestone for Chinese long-range strike capabilities.

“With four tests in about a year and a half, it is possible that China could conclude development of an early version for deployment in one to two years,” said Rick Fisher, a China expert with the International Assessment and Strategy Center.

Former Pentagon official Mark Stokes, also a China weapons specialist, said the People’s Liberation Army and China’s space and missile industry have been conducting engineering design work on a boosted hypersonic glide vehicle for some time. “Certification of the design requires prototype testing of the post boost vehicle, which is probably what’s going on,” said Stokes, now with the Project 2049 Institute, a think tank.

“Fielding of a hypersonic glide vehicle would advance the PLA’s ability to hold U.S. targets at risk, as well as those of allies and partners,” Stokes added.

Lora Saalman, a professor at the Daniel K. Inouye Asia-Pacific Center for Security Studies, the latest Wu-14 test indicates the weapon is a high priority.

“This test is keeping in line with China’s fast-tracking of this program and efforts to expand not just the range but also the capabilities and maneuverability of the system,” she said.

Fisher said he suspects an early version of the Wu-14 will be launched atop a DF-21 medium-range ballistic missile, although in the future it would be carried by the 2,485-mile range DF-26.

“Perhaps the most important U.S. antidote for China’s hypersonic maneuvering warhead is U.S. energy weapons programs,” Fisher said.

“There is an urgent need to increase funding to accelerate the early deployment of rail gun weapons.”

Rail guns fire shotgun-style pellets at hypersonic speeds that create pellet clouds that can be used to damage or destroy Chinese hypersonic warheads.

“It is urgent that the U.S. speed the deployment of rail guns to defend aircraft carriers, large combat ships, and major U.S. military facilities in Asia,” he said.

“The U.S. also needs to accelerate the development of its own hypersonic weapons, ground, air, and sea-launched, to deter China’s use of these weapons.”

The current House version of the fiscal 2016 defense authorization bill calls for the Pentagon to conduct advanced technology war games, including those involving hypersonic strike systems.

The bill includes $291 million for an extended-range variant of Army’s Terminal High Altitude Area Defense, or THAAD, missile defense system to deal with hypersonic threats.

“The committee is aware of the rapidly evolving threat from potential adversaries’ development of hypersonic weapons,” the report on the bill says, noting China’s several recent tests.

“The [Armed Services] committee believes this rapidly emerging capability could be a threat to national security and our operational forces,” the report said.

The Army has conducted two tests of its Advanced Hypersonic Weapon and in the latest test the missile launcher blew up shortly after liftoff.

The committee called on the military to develop hypersonic targets to improve U.S. defenses.

A Chinese Embassy spokesman did not return an email seeking comment.

In the past, China’s government has called the hypersonic tests normal military experiments.
 
Don't get me started. :) 4 flights in 18 months is very impressive when you compare it to our two flights and final decision to not try for a third.

But hey if we go back and navel gaze for a few more decades a Mach 20 boost glider will magically pop up in the turnip patch.
 
How many more studies and white papers does it take to get that turnip garden to sprout?

At least 47 powerpoints and 12 programs killed in the cradle.

"The Senate Appropriations defense subcommittee is reporting a fiscal year 2016 bill to the full committee that adds nearly $3 billion to the Defense Department's $107 billion procurement request, as well as an additional $540 million to DOD's $70 billion research and development request."

Can we not find adequate resources to fund multiple hypersonic PGS weapons with $177 billion of procurement and R&D?
 
New article on the SR-72 with a very small amount of extra detail in the text. Think this might be a cut down article from the one in the magazine.
