Fourth Team To Join JMR Rotorcraft Studies

Sep 2, 2011


 
By Graham Warwick
 
 
A fourth team is to join Boeing, Bell-Boeing and Sikorsky in competitively studying concepts for the Joint Multi Role (JMR) medium utility rotorcraft, which could replace U.S. Army UH-60 Black Hawk helicopters beginning late next decade.

Boeing, Bell-Boeing and Sikorsky were awarded 18-month configuration trades and analysis contracts at the end of June. Each is worth around $4 million, with industry contributing a similar amount.

“We are negotiating with one more, and should award a contract in the next couple of weeks,” says Ned Chase, platform technologies division chief at the Army’s Aviation Applied Technology Directorate (AATD). He spoke Aug. 31 at a conference in Patuxent River, Md., organized by vertical-lift technical society AHS International.

Concept studies are the first step toward the planned awarding of contracts to build two different JMR technology demonstrators that would fly by fiscal 2017 as a precursor for development of a new medium utility rotorcraft to be fielded around 2027-28.

The three teams already under contract are taking different approaches. One is “doing a deep dive on a single configuration,” Chase says. Another is studying three different concepts, while the third is looking at all possible options, he says.

Bell Helicopter CEO John Garrison has said previously that the Bell-Boeing team responsible for the V-22 Osprey proposed a tilt-rotor configuration for the JMR studies.

The fourth contract is taking longer to negotiate because the unidentified entity is not as experienced in contracting with the Defense Department, “but they have a good proposal,” Chase says.

The Pentagon has compiled a list of desired attributes for a JMR family of vertical-lift vehicles to replace its current fleet of helicopters, including the AH-64D Apache, UH-60M Black Hawk and CH-47F Chinook. These include 200-kt.-plus speed, 230-nm combat radius, 6,000-ft./95F hot/high performance and increased affordability, durability and survivability.

The configuration studies “will distill out the things that bring the most value, and get from a list of attributes to the design requirements for a next-generation rotorcraft,” Chase says. “They will provide the performance specification for the demonstrator aircraft.”

The same list of attributes for a medium utility JMR have been supplied to an independent government design team that is looking at advanced helicopter, compound helicopter and tilt-rotor concepts, Chase says.

The government designers are providing data on the three configurations to an operations analysis team at Fort Rucker, Ala., which will run scenarios to establish the relative operational values of the desired attributes.

AATD plans to award multiple contracts in fiscal 2013 to begin design of JMR demonstrators. Following preliminary design reviews, the Army in fiscal 2015 will downselect to two contractors to build the aircraft.

Phase 1 of the demonstration will involve flight tests of the demonstrator air vehicles. Phase 2, following two years later, will involve the design and integration of open-architecture mission systems into the demonstrator aircraft.

Army Begins Defining Future Vertical-Lift

Sep 14, 2011


 
By Graham Warwick
Washington
 


Finally responding to calls from operators and industry to begin work on replacing its hard-pressed helicopter fleets, the U.S. Army is moving ahead with a program to develop the next generation of rotorcraft. But the service faces a challenge securing sufficient government and industry funding to sustain competition until a development program can begin around the end of the decade.

The Army has kicked off the Joint Multi-Role (JMR) program not knowing exactly what it wants or which of its helicopter fleets it will replace first. Instead it has a list of desired attributes and a rough timescale—2027-28—for fielding its first all-new rotorcraft in 50 years. The task of turning those attributes into requirements for a next-generation aircraft falls to a pair of technology demonstrators the service plans to build and fly in 2017.

In a sign the Army is getting serious, its budget for rotorcraft science and technology (S&T)—which has long run at a mere $100 million a year—is being augmented for the JMR demonstrators. But additional funding, as well as industry cost-sharing, will be needed if the service is to fly two robust demonstrators with mission systems and so keep its competitive options open.

“It’s a major breakthrough that we are not flat-lined at $100 million and they have been successful in getting Army leadership to increase S&T funding for the JMR demonstration,” says Michael Hirschberg, executive director of American Helicopter Society (AHS) International, a technical body. “It remains to be seen whether it will be enough to do everything they want the technology demonstrators to do.”

JMR is seen as a family of vertical-lift vehicles, from light to ultra-heavy, sharing common technologies. As a starting point, the Army has selected the middle of the range and the medium utility JMR. Not only would this replace the Sikorsky UH-60 Black Hawks that make up its single largest helicopter fleet, but studies over the next two years will show to what extent technologies required in a medium utility JMR could scale down to the light scout and up to the heavy transport classes.

Distilled from several recent Army and Pentagon-level analyses that identified gaps in U.S. rotorcraft capabilities, the list of desired attributes for the JMR family of vehicles includes speed exceeding 200 kt., up from less than 150 kt. for today’s helicopters, a combat radius of 230 nm and 6,000-ft./95F hot-and-high performance. In addition to better affordability, durability and survivability, other attributes include a common core avionics architecture and an optionally manned capability.

“The capabilities demanded cannot be achieved through upgrading the current fleet,” says Ned Chase, platform technologies division chief at the Army’s Aviation Applied Technology Directorate (AATD). “We want to build two technology demonstrators to pursue capabilities lacking in the current fleet while maintaining competition and providing different alternatives.”

The list of attributes for the medium utility JMR has been provided to three industry teams that received configuration trades and analysis contracts at the end of June. Awarded to Bell Boeing, Boeing and Sikorsky, the 18-month contracts are each worth $4 million, with industry contributing a similar amount. “We are negotiating with one more, and should award a contract in the next couple of weeks,” says Chase.

The configuration studies “will distill out the things that bring the most value, and get us from a list of attributes to the design requirements for a next-generation rotorcraft,” he says. “They will provide the performance specification for the demonstrator aircraft.”

The JMR demonstrators will not be prototypes, as the YUH-60 and -61 were for the Black Hawk or YAH-63 and -64 for the Apache. For one thing, they are expected to be smaller than the objective vehicles to reduce cost. And secondly, Chase says, the Army has committed to industry to have another competition for development and production.

The three teams already under contract are taking different approaches. One is “doing a deep dive on a single configuration,” says Chase. Another is studying three different concepts, while the third is looking at all possible options, he says. Bell Helicopter CEO John Garrison has said previously that the Bell Boeing team responsible for the V-22 Osprey proposed a tiltrotor configuration for the JMR studies. The fourth contract is taking longer to negotiate because the unidentified entity is not as experienced in contracting with the Defense Department, “but they have a good proposal,” says Chase.

The same list of attributes for a medium utility JMR has been supplied to an independent government design team that is looking at advanced helicopter, compound helicopter and tiltrotor concepts, he says. The government designers are providing data on the three configurations to an operations analysis team at Fort Rucker, Ala., which will run scenarios to establish the relative values of the desired attributes. “They will consider the performance of a fleet of aircraft to establish what operational value each attribute brings to the table,” Chase says.

“We need to understand which attributes are most important on the battlefield, and most cost-effective to implement,” he says. “We need to understand how to get the right mix of capabilities on the aircraft. The decisions we make will impact rotary-wing aviation operations for the next 50 years.”

The aim is to develop a draft requirement for the medium utility JMR—“it’s about this big, goes this far, does these things and we have an idea we can afford it,” Chase says—and use that to derive the demonstrator specification.

At the same time, an acquisition team involving the Army, Navy, Special Operations Command and other potential customers is developing an initial capabilities document (ICD) establishing the requirements for the JMR. This is expected to be completed by mid-fiscal 2012, says Chase. The ICD is a necessary precursor to an analysis of alternatives and Milestone A approval for a new acquisition program, and it is not clear yet whether the ICD will be for the overall JMR family of vehicles or just for the medium utility class.

“We have established a joint-service team through the Office of the Secretary of Defense’s Future Vertical Lift [FVL] working group,” he says. This brings together rotorcraft operators within the Pentagon and was directed by Congress to determine capability gaps, develop an S&T road map and strategic plan for vertical lift, and identify funds for technology development.

With the ICD in place, AATD plans to award multiple contracts in fiscal 2013 to begin design of the JMR demonstrators. Following preliminary design reviews, the Army in fiscal 2015 intends to downselect to two contractors to build the aircraft. “We are putting funding in place for two. They may be the same or entirely different configurations,” he says. Phase 1 of the demonstration will involve flight tests of the demonstrator air vehicles. Phase 2, following two years later, will involve the design and integration of two open-architecture mission systems into the demonstrator aircraft.

Work on defining the common core architecture has already begun. “We’ve started that first, to build a Defense Department/industry consensus on an open systems architecture,” says Chase, adding that the program office responsible for developing the Army’s Victory open architecture for combat vehicles is involved. The goal is to develop a common standard for a scalable architecture to be used in mission-system development in Phase 2. As with the air-vehicle Phase 1, the plan is to award two demonstration contracts to avionics integrators “as a hedge against risk,” says Chase.

With U.S. military rotorcraft production facing a cliff around the end of this decade as procurement programs end, AHS has been campaigning for more investment in technology development to sustain industry capabilities and lay foundations for the next generation.

“The Defense Department needs to ensure there is enough funding for the JMR demonstrators to really be relevant,” says Hirschberg. “This is the Pentagon’s one chance to realize a significant advancement in capabilities—they can’t afford to be timid.”

AVX Wins JMR Helo Study Contract

Sep 30, 2011


 
By Graham Warwick graham_warwick@aviationweek.com
WASHINGTON

 
 
 
AVX Aircraft, a small Texas company staffed largely by former Bell engineers, has won a U.S. Army contract to study a potential replacement for the Sikorsky UH-60 Black Hawk utility helicopter.

AVX joins Bell Boeing, Boeing and Sikorsky in conducting 18-month configuration analysis and trade studies for the Joint Multi Role (JMR) program, which aims to fly two competing rotorcraft demonstrators in 2017.

No further awards are anticipated, says the Army’s Aviation Applied Technology Directorate, which is managing the JMR technology demonstration program.

Under its contract, the Forth Worth-based company will identify technologies and develop concepts for both a demonstrator and an objective medium-utility rotorcraft that could enter service in the 2025-30 time frame.

AVX’s design will feature a coaxial rotor and ducted fans for propulsion and control — a similar configuration to that being proposed by the company to upgrade the Army’s Bell OH-58D Kiowa Warrior to meet its Armed Aerial Scout requirement.

Bell Boeing is studying a tiltrotor, Boeing is looking at a range of configurations and Sikorsky is evaluating an advanced helicopter, tiltrotor and a compound helicopter using its X2 high-speed coaxial-rotor configuration.

The study contracts are each worth around $4 million, with the major manufacturers matching the government funding for a total of $8 million. “We will be close to that,” with funds from the company and nine industry partners, says Ian Brown, AVX director of program management.

AVX also is talking to industry partners and private investors about funding a demonstrator for the OH-58D upgrade. This would take a commercial Bell 206L and fit it with coaxial rotors, ducted fans and new transmissions.

The demonstrator could be flying within 18 months of go-ahead, Brown says, and would be flown for about a year to validate the configuration being offered to the Army. A 206-based design also could find application in the commercial market, he says.

JMR - Tiny AVX Joins the Big Boys

Posted by Graham Warwick at 9/29/2011 3:26 PM CDT 


Fort Worth, Texas-based AVX Aircraft is the mysterious fourth team to win a $4 million contract from the U.S. Army to study concepts for the Joint Multi Role (JMR) medium replacement for the UH-60 Black Hawk.


[IMAGE CREDIT: Ares blog/ Aviation Week]

AVX, staffed largely by former Bell Helicopter employees, is best known for its proposal to meet the US Army's Armed Aerial Scout requirement by upgrading its OH-58D/F Kiowa Warriors with coaxial rotors and ducted fans, which would replace the tail rotor and provide both control and propulsion.

AVX is still pursuing the OH-58 upgrade, and working to corral funds from industry partners and private investors to build a demonstrator, but the JMR contract is the first time it finds itself head-to-head against the big players. Three other 18-month configuration analysis and trade study contracts have been awarded by the Army's Aviation Applied Technology Directorate: to Bell Boeing, Boeing and Sikorsky.

Under the cost-sharing contracts, the companies will identify and prioritize technologies to meet the Army's desired attributes (which include a speed of at least 200kt), and develop concepts for both an objective JMR medium rotorcraft that could enter service in 2025-30 and a technology demonstrator that could fly in 2017.

I think that JMR deserves its own topic. I also recommend to visit the AWX Aircraft website for the nice high-res images:

Ha! That will teach Bell what happens when you dump half of your development staff on the street.
It would be nice to have a little competition back in the rotorcraft industry.

I'm no aerospace engineer and pardon my ignorance but the coaxial rotor system employed by AVX (based on the concept drawings) seem to resemble those employed on the Kamov series. Would they not present a high drag profile when they are being offloaded by the ducted fans?

Yes, coaxial rotors do impose some drag penalties, but they're not insurmountable.  Even in a straight helo comparison, detailed design can matter more -- the coaxial Ka-50 is a hair faster than the conventional Mi-28 on the same engine power and roughly similar weights.

Maybe not so sure. Piasecki is very much alive and still a company. Boeing can only claim the technology developed by Piasecki prior to the takeover, circa 1960. All technology developed afterwards (which culminated in the X-49 Speedhawk and all the related designs) is in the hands of Piasecki.

I think your news of Piasecki being a sub element of Sikorsky might be a surprise to Mr's. Piasecki. I think you are mixing them up with Schweitzer Aircraft that was bought out by Sikorsky.

True.  :-[ And it's not the first time I've made that mistake! What confused me was the X-49 Speedhawk, which is a Piasecki program using a Sikorsky helicopter. And yes, I got confused with Schweizer, which has indeed become part of Sikorsky...  :-\

My deepest apologies to whomever might have been offended by my mistake, especially people from Piasecki — if ever they visited this site... I have the deepest respect for Mr. Piasecki's visionary take on rotorcraft, which are at long last developing in full swing, and very glad to see so many new projects emanating from the current Piasecki company!  ;)

I must not be in the know because I am  not familiar with the abbreviation 'ASAH' in this context, and neither, apparently is Google. 

That aside, it's not particularly obvious at this point that Tilt-Rotor would be dramatically more expensive than other concepts shown, most of which are not as mature as it is.
