Rolls-Royce completes HiSTED YJ102R engine test
By Rob Coppinger
Rolls-Royce has completed an initial test of its YJ102R engine for the US military's High Speed Turbine Engine Demonstration (HiSTED) programme.
HiSTED is a joint Defense Advanced Research Projects Agency, Air Force Research Laboratory (AFRL) initiative to design, fabricate and ground test a "high Mach expendable turbine". The HiSTED engine is a high-temperature, moderate-pressure-ratio, single-spool, non-afterburning turbojet. It incorporates Rolls-Royce's "Lamilloy technology", which is designed to enable engines to run at higher temperatures allowing greater fuel economy.
Additional engine testing is scheduled to demonstrate its ability to achieve transonic acceleration and Mach 3-plus cruise speed. The engine could be used to propel the US Office of Naval Research's Revolutionary Approach to Time-critical Long Range Strike vehicle, a supersonic, science and technology missile flight demonstrator.
"The HiSTED programme is a classified US programme and we are unable to share any additional information," R-R told Flight International. The YJ102R engine test was carried out at its Indianapolis, Indiana facility by the Rolls-Royce North American Technologies research unit, also known as LibertyWorks.
Other USAF programmes R-R is involved in include Highly Efficient Embedded Turbine Engine (HEETE) and Adaptive Versatile Engine Technology (Advent). In September 2007 R-R was awarded $19.6 million for HEETE, which is part of the USAF's Versatile Affordable Advanced Turbine Engines programme. And in August of that year the company was awarded a $296 million USAF contract for Advent. Advent will focus on the development of variable cycle features that will enable a high-thrust capability and a separate loiter operation with reduced fuel consumption.

One treaty (INF?) limits the range of such missiles to 500 km.

The picture of LRASM posted in another thread here doesn't remotely resemble RATTLRS. (I was hoping RATTLRS would be the one chosen for LRASM-B but apparently RATTLRS has never even been captive-carried.

I don't understand. As you can see above, the 2009 plans were for completing the flight test plan and data reduction. The flight test program was initiated in FY2008, with data reduction continuing through 2009. This is covered in the RDTE descriptive summaries for PE 0603114N "Power Projection Advanced Technology". The 2011 RDTE summary listed completion of the flight test program as a 2009 accomplishment. This is all in the public domain and available online.
RATTLRS is not listed in the RDTE summaries for that PE code for 2010/2011, but LRASM is. For 2009 both were.
"The committee notes that although it is widely agreed that the best opportunity for near-term transition of hypersonics technology will be in cruise missile or conventional strike systems, especially to support time critical and prompt global strike missions, suffi- cient resources for research, development, or testing of the systems has never been focused, coordinated, or sustained within the De- partment of Defense. Examples of these programs include the DARPA Falcon Hypersonic Technology Vehicle (HTV–2), the Air Force’s X–51 program and the now terminated HyFly and Revolu- tionary Approach to Time Critical Long-Range Strike Project (RATTLRS) programs. The committee feels that these programs have all suffered from a lack of investment in addressing funda- mental technical issues and insufficient resources for required flight test and demonstration activities." - Senate Armed Services Committee, FY2009 RDTE request comments (SASC_110-335_RDTE)

RATTLRS full-scale mockup at KNTD in the Fall of 2006 for display at a "Friends and Family Day". Images (c) me. Virtually nothing about the program has surfaced since. To me, this would leave two alternatives:
1) The program ran out of money and died a painful death in obscurity, or
2) The program went sub rosa and then succeeded or failed in obscurity.

More like the programs were not well coordinated or resourced, and as such were wasting money. How much of an investment had been made in range support for this kind of testing?
Not much. Those kinds of problems were not well thought through. Imagine you had 5 super duper new fighters in development, but no place like Edwards to test them. Instead each fighter program was paying for different testing resources.
But with RATTLRS, there is no indication that anyone felt it was too hard. It completed its flight test program. There was never a concrete plan to turn RATTLRS into an operational system.

So why no pictures,video or articles discussing the test flights? You'd think, given all the hype and publicity around RATTLRS they'd have said something. The question I have is why nobody seems to be interested in making a concerted to developing high-speed technologies in the US. The image that comes to mind is a bunch of monkeys trying to have relations with a football.

Many of the Navy programs at Pt. Mugu and China Lake never produce public photos. It's just not the way they do things. You can contact public affairs at ONR and see if they can provide anything. They may even be able to tell you the disposition of any remaining hardware.
No, there are several different organizations that are developing different solutions in parallel. That's the problem.
NASA and DoD did have a national hypersonic development program. The various reasons that did not pan out, and why it is not viable in today's political climate, are beyond the scope of this thread.
The fate of RATTLRS, however, seems clear.

Portions of HiSTEAD are now part of the Mode Transition Demonstration program funded under PE 0603286. It is not clear that the HiSTEAD engine completed testing, but appears likely.

HiSTED, not HiSTEAD, and it's LibertyWorks YJ102R
Sferrin, look back at your own posting

"From an article in this weeks AvWeek:
"Current trials continue to use the 70%-scale PWR-9221FJ engine, and “we will be using a single turbojet engine for the demonstration,” DeFreese adds. The original HTV-3X was to be powered by two turbojets and a single -9221. The final choice of high-speed turbojet is yet to be determined between the two Histed ramburner-configured engines. These are Rolls-Royce Liberty Works’ XTE18, also known as the YJ102R, and Williams International’s XTE88."
The YJ102R is the RATTLRS engine."

Despite my misspelling, and incorrect program alignment, I believe there have been real issues with both high Mach turbine tests. Also, fwiw MoTr is dead. Note the "new Darpa MoTr PM" Tom Bussing is no longer at Darpa.

DARPA requested money for it through 2011 (under 0603286E), in a month or so we should know where it went and how much they want for coming years.

I like the GE57 approach with some bits added, that I don't want to discuss.

Sometimes you only need to know *exactly* what questions to ask. For example, doing a FOIA or other records search asking for "TACIT BLUE" will not yield much, but...
"Battlefield Survivable Aircraft Experimental, funded by DARPA from 1978 to 1985, managed by the USAF aeronautical systems center (as of 1999 the aeronautical systems center of air material command), and flown by the Special Projects Flight Test Squadron, a unit of the 416th flight test squadron, at the National Classified Flight Test Facility".
That would give you much better chances than just having them search for a code word. As best you can, answer who, what, where, when, and how in your queries to organizations and people.
There is enough information just on this forum to ask the right questions about several high speed projects from the 80s, like the BGV/Axe and similar, and various MaRVs. I don't have the time myself to do it the right way, and I don't get paid to do it

is the Vulcan effort part of this? because I get confused at all the different names. :-\
Vulcan is the TBCC, turbine + PDE, program which started out as an aerospace application, but was transitioned to looking at shipboard applications for Phase 2. MoTR was the TBCC, turbine + scramjet, program which morphed out of the Blackswift portion of FALCON. One of the major causes for confusion, imo, what that the industry day briefing for Vulcan contained info pointing towards a possible future combination with a scramjet as well, though the program was really focused on a nearer term solution of mating a current large scale turbine (ala F-100) with a PDE system in ground tests. There was a facility study which looked at how current ground test facilities might handle the requirements and scale of such a test.

Yup - Vulcan is all about shipboard power now. - "Application of this technology is expected to reduce turbine fuel consumption by 20 percent, resulting in a savings of approximately 65 gallons per hour compared to existing DDG-51 Class gas turbine generator sets."
