Coulson’s CU-47 is ready for the fire fight

Posted on May 22, 2020 by Howard Slutsken

Leveraging its experience with fixed-wing air tankers, Coulson Aviation has unveiled its latest aerial firefighting conversion, based on the Boeing CH-47D Chinook heavy-lift helicopter.

In early March, the first Coulson-Unical CU-47 was flown from the company's Port Alberni, B.C., base to the Aerial Firefighting North American 2020 conference in Sacramento, Calif.

Featuring a 3,000 gallon roll-on/roll-off internal tank and an advanced Garmin avionics suite, up to 12 CH-47Ds will be converted into next-generation heli-tankers, in a partnership with Unical Aviation that was

announced a year ago.

“Unical provides us with the aircraft and a vast supply of parts,” explained Britt Coulson, president and COO, in an interview with Skies.

“They bought the entire Canadian Forces CH-47 parts inventory and were the largest purchaser of CH-47Ds from the U.S. Army.”

The twin-rotor Chinook is well known for its speed, size and payload. While the helicopter is often deployed on fire attack missions carrying a water bucket as an external load, Coulson wanted to give the CU-47 more flexibility and capability.

The company's engineers had already developed a 4,000 gallon Retardant Aerial Delivery System RADS-XXL for its Lockheed C-130 Hercules tanker conversions, and that tank was shrunk to create a 3,000 gallon RADS-L for the CH-47D conversion.

“It's the same overall design as the C-130. It shares most of the same hydraulic components, the same doors and the same design of a roll-in, roll-out tank,” said Coulson.

Other CH-47 internal tank systems utilize the small hook well in the centre of the helicopter as the water and retardant delivery port, but according to Coulson, that has its limitations.

“The other tank designs are plagued with flow rate issues, which means they don't pack enough punch to really get through [forest] canopies or drop in heavy timber – the hook well opening just isn't big enough.

“The lower the flow rate you have out of your tank, the slower and lower you have to fly. The problem with a big helicopter like a Chinook is if you fly too slow and low, your downwash is going to negatively affect the ground fire conditions and your drop is going to be ineffective.”

To increase and optimize the flow rate for the RADS-L, the belly of the CH-47D was modified by cutting the helicopter's lower skin and adding structure below the floor to accommodate the tank installation and a pair of drop doors, controlled by the pilots through a state-of-the-art touchscreen controller.

From the same touch panel, the pilots also control the CU-47's newly-developed retractable snorkel system to refill the RADS-L tank from water sources close to a fire's location.

Installed internally, the snorkel head sits flush with the belly when retracted, so that with no additional external drag, the helicopter can maintain its fast 140-knot cruise speed.

In a hover, the snorkel takes just four seconds to deploy and six seconds to retract, and the pilots and flight engineer can monitor the system's operation via a high-definition belly-mounted camera feed, displayed on the touchscreen controller.

“The snorkel system has exceeded our expectations and we're filling the entire tank in under two minutes,” said Coulson.

With the advanced capabilities of the Garmin avionics, the relocation of the flight engineer's panel, and the new RADS-L tank, Coulson originally believed that the CU-47 could be crewed solely by two pilots, without a flight engineer. But recent operational experience led the company to rethink that strategy.

“We realized that with a helicopter of this size, going into some of the smaller dip sites, to have an additional set of eyes looking out the side or back is valuable to the pilots. So we've de-modified the helicopter and gone back to a full-time flight engineer to provide that increased safety and situational awareness.”

Like Coulson's C-130 conversions, the CU-47 can also be tasked with night-time firefighting missions, thanks to the Night Vision System (NVS)

certification of the helicopter's avionics suite.

Wearing NVS googles, the CU-47's crew work in tandem with a fire attack “Intel” helicopter's pilots. The Intel crew uses a thermal camera to evaluate the behaviour of a fire, and if a drop is required, they take a page from military ground-attack operations. Using a laser, the Intel crew designates the target for the tanker.

“With a geo-referenced lock, the Intel helicopter can orbit, and the laser beam will stay on the same spot. It illuminates an area on the ground about the size of a car,” said Coulson.

The first CU-47 will soon be joined by a second RADS-L equipped helicopter, two CU-47's with upgraded avionics that will fly “bucket” missions, and a fifth, tank-equipped CU-47 that will deploy as a spare.

“All of our FAA testing [on RADS-L] has finished, we're just waiting for the final Supplemental Type Certificate signature,” said Coulson. “We're doing some minor cleanup to the helicopter to make sure that it's ready to go fight fires this summer.”

Howard Slutsken's lifelong passion for aviation began when he was a kid, watching TCA Super Connies, Viscounts, and early jets at Montreal's Dorval Airport. He's a pilot who loves to fly gliders and pretty much anything else with wings. Howard is based in Vancouver, B.C.

    Pentagon turns to new buying tools 10 times more often

    By: Aaron Mehta WASHINGTON — The amount of funding for defense research awarded through other transaction authorities have increased nearly tenfold in five years, according to a new analysis seen exclusively by Defense News. The report, by data and analytics firm Govini, shows the use of OTAs and small business innovation research contracts has expanded to the point that, in 2019, the two methods accounted for $9.6 billion, or 10 percent of the Defense Department's research, development, test and evaluation spending. OTAs are small contracts awarded to companies of any size, in theory targeted at nontraditional defense contractors, with the purpose of conducting research or prototype efforts on a specific project; they are not subject to Federal Acquisition Regulation rules. SBIR contracts are targeted at small businesses in order to act as seed money for them to conduct research and development efforts; they are subject to the FAR rules. Overall, $34.5 billion have been handed out in the last five years through the two contracting methods, to 6,503 unique vendors. However, more than half the OTA dollars are going to only three consortia. The two contracting methods may be about to jump in importance for the department, in light of the new coronavirus outbreak. Navy acquisition head Hondo Geurts, in a March 24 memo, ordered his workforce to do what they can to keep small companies assigned to naval research programs on track, including specifically calling out the need to protect SBIR efforts. Govini tracked the use of OTA and SBIR contracts over a five-year period, from fiscal 2015 through fiscal 2019. “The Defense Department's surging use of OTAs reflects its strong desire to break free from the stringent acquisition process, better access innovative technologies, and lure new companies to the defense ecosystem who otherwise may not see the federal government as a viable or lucrative potential market,” said Tara Murphy Dougherty, Govini CEO. “Fundamentally, the Department is driven by the imperative to outpace China's military modernization in order to retain a military advantage, and they understand that leveraging emerging technologies and the very best technology available in American industry — not just the Defense Industrial Base — are critical to achieving that goal,” she added. OTA dominance The numbers tell a particularly stark story of how the department is increasing its use of OTA contracts. From 2015-2017, the government awarded $12.5 billion in SBIR contracts, versus $4.9 billion in OTA contracts. But from 2018-2019, the government awarded $5.7 billion in SBIR contracts, while it handed out $11.4 billion in OTA deals — an increase large enough to nearly draw even over the five-year period. That increase in OTA funding also ties into the mission laid out by the National Defense Strategy, which encourages a focus on great power competition with China and Russia. According to Govini, the two biggest OTA investments of RDT&E dollars during this time period were $5 billion for munitions and long-range fires, and $3 billion for space systems. While the dollar totals are becoming closer, overall SBIR recipients continue to dwarf OTAs — 6,213 to 290 during the five-year period. In the number of OTA awards per service, the Army leads the way. (Govini) The Army leads the way with use of the two contract methods ($14.1 billion) during this period, followed by the Air Force ($10.4 billion), defensewide agencies ($6 billion) and the Navy ($4 billion). The two contract types also split their dollars in divergent ways. The top SBIR vendor, Colsa Corporation, received 4 percent of total SBIR awards, and the top ten (which includes Colsa) received less than 20 percent of the overall total. In comparison, the top three OTA vendors are consortia managers that make up more than half of total OTA contracts. Those three are Analytic Services Inc. ($5.429 billion), Advanced Technology International ($1.616 billion) and Consortium Management Group Inc. ($1.238 billion). Traditional defense corporations are taking advantage of OTAs as well. The fourth highest recipient of OTA money is United Launch Alliance, co-owned by Lockheed Martin and Boeing; the sixth highest recipient is Lockheed; the eight highest is Northrop Grumman; and the 10th highest is Boeing. Given that OTAs were designed to reach out to nontraditional defense firms, “it's surprising how many traditional defense contractors benefit from OTA arrangements,” Murphy Dougherty said. “Lockheed Martin, Northrop Grumman, and Boeing were all top OTA vendors over the past five years. This is a good example of how accessing the data can help the Department measure its success in terms of achieving intended outcomes through actions like increased OTA use.” Earlier this month, Ellen Lord, the Defense Department's top acquisition official, was asked at a McAleese & Associates conference about data that shows prime contractors taking advantage of OTA contracts. Lord indicated her office needed to gather more data on the issue before taking a look. “The whole premise of OTAs was to get the nontraditional [vendors] and the smalls there,” Lord responded. “I find it hard to imagine a situation where large primes would predominately use OTAs, but I don't know what I don't know. That wasn't the objective. “Oversight is one of our responsibilities in A&S [the office of acquisition and sustainment] that I take very seriously, so we need to make sure that we don't have unintended results from some of the polices that we implement. We're always trying to improve that.” https://www.defensenews.com/industry/2020/04/01/pentagon-turns-to-new-buying-tools-10-times-more-often/

    DIA announces winners in massive intelligence technology contract

    By: Brandon Knapp The Defense Intelligence Agency (DIA) awarded spots on a contract worth up to $500 million to eight defense companies and one research organization as part of the agency's effort to buy research, development, technical, and engineering services for intelligence missions, according to an announcement from the Department of Defense Sept. 14. DIA selected AT&T, Booz Allen Hamilton, Harris Corp., KeyW Corp., Leidos Inc., Lockheed Martin Corp., Macaulay-Brown Inc., Northrop Grumman Corp., and Southwest Research Institute for the procurement program, known as HELIOS. The companies won five year contracts that include five additional one-year options. The award winners will have multiple opportunities to compete for task orders on the indefinite delivery / indefinite quantity contract in support of DIA Directorate for Science & Technology missions. Unclassified documents released in 2017 describe in part the scope of HELIOS as offering support services for “sensor technology focus areas including Measurement and Signature Intelligence” as well as “cross-cutting technology areas such as unattended remote sensing, robotics...and data processing, exploitation and dissemination.” Mission areas for HELIOS include space situational awareness, foreign counter space threats, the Internet of Things, data exfiltration, and rapid prototyping. The Virginia Contracting Activity received nine responses to their original open solicitation posted in Dec. 2016. All nine solicitors received a contract with a minimum award of $10,000. The HELIOS program has an estimated completion date of September 2028. https://www.c4isrnet.com/intel-geoint/2018/09/18/dia-announces-winners-in-massive-intelligence-technology-contract

    Qu’est-ce que la Base industrielle et technologique de défense (BITD) ?

    DEFENSE Qu'est-ce que la Base industrielle et technologique de défense (BITD) ? Selon L'Opinion, l'ancien candidat LREM à la mairie de Paris et porte-parole du gouvernement Benjamin Griveaux se serait vu confié en tant que député une mission sur la « Base industrielle et technologique de défense » (BITD). Durant deux mois, il serait chargé avec le député Les Républicains Jean-Louis Thieriot de se pencher sur la place des industries de défense dans le plan de relance post-Covid-19. L'occasion pour l'Usine Nouvelle d'expliquer dans un article ce qu'est la BITD. L'Observatoire économique de la Défense, rattaché au ministère des Armées, établit chaque année cette Base industrielle et technologique de la défense. Elle regroupe l'ensemble des entreprises contribuant directement ou indirectement à la production ou au maintien en condition opérationnelle des armements : elles sont soit fournisseurs directs du ministère des Armées, soit sous-traitants des grands maîtres d'oeuvre industriels de la Défense. En 2018, il s'agissait d'une dizaine de grands groupes de taille mondiale (groupe Airbus, Dassault Aviation, Naval Group, MBDA, Nexter, Safran, Thales...) et 4 000 PME, soit environ 200 000 emplois, qui étaient comptabilisés.
