As we reported in March, Coulson Aviation is partnering with Unical Air, a new unit of the Unical Group of Companies, to create a heavy lift helicopter joint venture company that will build and operate Boeing CH-47 and Sikorsky UH-60 Blackhawk aircraft for aerial firefighting and other markets.
By 2020 the company expects to have 10 additional helicopters between the two types.
Coulson Aviation is expanding their aircraft fleet. Until a few weeks ago the company had four C-130 type fixed wing air tankers, one converted Boeing 737 air tanker (with another that is 60 percent complete), and a mixture of five S-61 and S-76 helicopters.
Today Coulson announced a new partnership with Unical Air, a new unit of the Unical Group of Companies. The organizations have joined forces to create a heavy lift helicopter joint venture company that will build and operate Boeing CH-47 and Sikorsky UH-60 Blackhawk aircraft for aerial firefighting and other markets. Coulson’s expertise in the operation of heavy lift and firefighting helicopters will mesh with Unical Air’s abilities in supply chain, and parts, plus aircraft maintenance, repair and overhaul (MRO) and component repair and overhaul (CRO).
“When we met Unical, our companies meshed very well,” Britt Coulson, Coulson Aviation’s vice president, said. “Since both are family owned and extremely passionate about what we do, it was a natural fit to work together. Others that have bought either of these types has struggled with serviceability and parts support and with our partnership we are confident that will not be an issue.”
The capabilities of the helicopters will include night-vision, IFR navigation, and hover filling.
At least some of the newly acquired CH-47s and UH-60s will be outfitted with RADS internal tanks. The basic design of the RADS was created by Aero Union decades ago and features steep slopes on the sides when space allows, to facilitate enough head pressure at the bottom to ensure quick and constant flow. The technology used will enable automated target drops for the night vision goggle firefighting program and will have the capability to adjust flow rates based on speed and altitude. A Coulson helicopter that has been certified in Australia for night drops has been used on a regular basis for the last several months during the country’s 2018-2019 bushfire season.
Coulson has engineered several different sizes of the tanks to enable them to be used in a variety of aircraft, including the C-130 and the 737. The CU-60 will carry up to 1,000 USG, and the CU-47 will carry up to 3,000 USG.
The snorkels used for hover refilling will be a brand new Coulson design, using an electrically-powered pump which will retract into the belly allowing flight to and from the fire with no speed restrictions, along with the ability to taxi around airports or tanker bases.
Instead of the water or retardant flowing through a relatively small opening at the cargo hook, Coulson will modify the bellies of both the CH-47 and UH-60.
“We are cutting the lower skin and adding in structure between the frames, the same way we have done on the C-130 and B-737 to create the optimal, linear door opening”, Mr. Coulson said. “We are also engineering the tank to incorporate the hook which will allow us to longline with the tank installed.”
The helicopters will be type certified and FAA approved, and the models will be renamed.
The helicopters will receive upgraded cockpits, featuring the Garmin G500H TXi synthetic vision displays and Coulson’s touch screen SMART Delivery System Controller for regulating the delivery of the water or retardant.
Coulson-Unical will have a CU-60 and a CU-47 at the HAI Heli-Expo in Atlanta, Georgia, March 5 to 7. Both have been painted but have not yet received the internal tank modification. The two ships will be available this year with conventional water buckets. By 2020 the company expects to have 10 additional helicopters between the two types.
CNN put together the above video about Los Angeles County’s Blackhawk helicopters, which they call Firehawks. The footage is impressive, and looks like an advertisement for Sikorsky and the maker of the “souped up” engines, General Electric. Some of the scenes actually did come from a commercial for GE that we had on our site in February.
