    Vertical lift drones brigades are assessing fly quieter with more survivability, soldiers say

    Kyle Rempfer Soldiers assessing aerial drones to help the Army replace its aging RQ-7 Shadow said the systems they've piloted can launch almost anywhere, offer a better chance of survival in combat against a peer adversary and have quieter motors that will prevent targets from detecting their presence. “There have been times where the Shadow is too loud to fly too close to an enemy, so we can't get many details on them,” said Pfc. Jacob Owens, a drone operator at the 1st Infantry Division who has been testing Arcturus UAV's JUMP 20 at Fort Riley. “Quieter can be a huge advantage to us because we can get closer to get details on the camera, like read a license plate on the back of a car.” Five brigades across the Army were selected to test unmanned aircraft systems and provide feedback to Army leadership looking to replace the RQ-7 Shadow, which was introduced in the mid-2000s. Owens and other soldiers spoke about the assessments they've participated in during a telephone call on Wednesday. Information gleaned from the assessments will inform the Army's future vertical lift cross-functional team as they develop specifications for a a future tactical unmanned aircraft system, which is supposed to sport advances in maneuverability, agility, lethality and reach, according to Army Futures Command. Futures Command began fielding the new drones to the five brigades across the force this spring, with 1st Infantry Division at Fort Riley, Kansas, receiving Arcturus UAV's JUMP 20 in mid-March. JUMP 20 is the largest of the four drones being tested, weighing in at 210 pounds with an 18-foot wingspan, which is roughly similar to the Shadow. The 17-hour flight time, vertical takeoff ability and reduced noise while in-flight will be a game-changer, said Sgt. 1st Class David Rodriguez, a platoon sergeant and standardization operator. “Without the noise, it allows us to get closer to targets and identify them over longer periods without being identified by the sound of the motors as we fly overhead,” Rodriguez added. The Army is looking for a Shadow replacement with reduced noise signature to retain the element of surprise and prevent targets from scattering if they see or hear the drone, noted the 1st Infantry Division Combat Aviation Brigade commander Col. Bryan Chivers, citing his experience in Afghanistan. “You could have a Gray Eagle or Predator [drone] on station, observing a particular target, and when the Shadow would come on-station, you knew because somebody announced it and if you were privy to the operation, you could see them looking up to the sky and sometimes hearing this system,” Chivers said. Vertical take-off is another specification the Army is seeking. It will allow launch and recovery at more locations, including austere ones without runways, and it should reduce the amount of equipment needed by soldiers. Soldiers at the 101st Airborne Division at Fort Campbell, Kentucky, have been testing out Martin UAV's V-BAT. The V-BAT is unique in that it sits on its tail end during launches. It has a lot less equipment, soldiers said, but its flight time is roughly the same as the Shadow. “We can pretty much operate it anywhere; We don't need a runway,” said Spc. Alexander Albritton, a drone operator at Fort Campbell. A lot of the requirements the Army has put forth stemmed from an increasingly important operational need to be more “expeditious,” according to Maj. John Holcomb, the future tactical unmanned aircraft systems assistant product manager. “One requirement we looked at for all the systems is the entire system could be loaded up on two Air Force 463L pallets and fit inside of a CH-47 [helicopter],” Holcomb said. “A Shadow system takes C-130s to get into theater and move around all the equipment that's required.” These future drone systems will allow tactical commanders to not rely on airfields, noted Lt. Col. Brian Angell, a squadron commander at Fort Riley involved in the tests. That could be important in a future fight against peer competitors like China and Russia that are able to pound stationary airfields and hangers with long-range weapons. “It opens up options,” Angell said. “We'll be less predictable. We'll be able to maneuver this system on the battle space quicker, set it up, operate it and move it to another location faster. So that's a survivability standpoint, as well, that we'll gain with this system.” A brigade at the 2nd Infantry Division on Joint Base Lewis McChord, Washington, began their own assessment of a third drone, Textron Systems' Aerosonde HQ, this week, according to Army Futures Command. Later in the summer, the 1st Armored Division at Fort bliss, Texas, is scheduled to test L3 Harris' FVR-90 drone. Futures Command hopes to complete the fielding process with a brigade from the 82nd Airborne Division in September, when the paratroopers will test a second version of Arcturus UAV's JUMP 20 with different payloads. The assessments will culminate with brigade-level combat training center rotations at Fort Polk, Louisiana, or Fort Irwin, California. Army officials have tentatively stated previously that the plan is to have the first unit equipped with a Shadow replacement sometime in fiscal year 2024. https://www.armytimes.com/news/your-army/2020/06/04/vertical-lift-drones-brigades-are-assessing-fly-quieter-with-more-survivability-soldiers-say/

    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. https://www.skiesmag.com/features/coulsons-cu-47-fire-fight
