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.

Eurofighter Typhoon defensive aids sub-system enhancement study contract awarded
The EuroDASS consortium, which comprises Leonardo, Elettronica, Indra and Hensoldt, will spend 18 months exploring future upgrades for the Eurofighter Typhoon's world-class electronic warfare system. The Praetorian Defensive Aids Sub System (DASS) is highly-regarded by users and has kept Eurofighter Typhoon crews safe throughout peace-keeping operations in Libya and Syria. The study will support the ability of the Eurofighter Typhoon's defences to keep pace with new technology and techniques employed by rapidly-developing threat systems. Leonardo, on behalf of the EuroDASS consortium, has received a contract from BAE Systems that will see the consortium explore the future of the Eurofighter Typhoon's ‘Praetorian' Defensive Aids Sub System (DASS). The ‘Praetorian Long Term Evolution (LTE)' study will lay the groundwork for future development work which will ensure that the Typhoon's Electronic Warfare system will remain one of the most advanced in the world for decades to come. The contract is a key part of the wider Eurofighter Typhoon LTE study, which aims to identify a suite of technology enhancements for the Eurofighter Typhoon's weapons system infrastructure and propulsion to provide a clear road map for the future of the platform. The Praetorian DASS is provided by the EuroDASS consortium, which comprises Leonardo, Elettronica, Indra and Hensoldt. It equips the Eurofighter Typhoon with advanced protection from threats including Infra-Red (IR or heat-seeking) and radar-guided missiles. The system is well-regarded by users and has been battle-tested on peace-keeping operations in Libya and Syria. The LTE project will enable Eurofighter Typhoon to be a survivable and effective combat aircraft out to 2060 against a background of accelerating technology development by potential adversaries. The Praetorian Defensive Aids Sub System (DASS) is the Eurofighter Typhoon's protection system, which integrates sensors and jamming equipment to provide exceptional situational awareness and a digital stealth capability for the aircraft, achieved through advanced electronic deception techniques. The Praetorian LTE study will evaluate potential future DASS requirements, enabling the aircraft to cope faster, easier and more affordably with new threats as they arise in the future. The study is expected to deliver options for long-term technical solutions and enablers which will sustain the growth path of the platform in the future. Options are likely to coverboth improved architecture, which new capabilities can be added to in a more agile and lower-cost fashion, and improvements to the exploitation and fusion of sensors to support the multi-role flexibility of the platform. A number of options will be explored and presented to the Eurofighter partner nations to support informed decision making. https://www.eurofighter.com/news-and-events/2019/09/eurofighter-typhoon-defensive-aids-sub-system-enhancement-study-contract-awarded
