The Army is turning to 鈥渄igital-twin鈥� technology from 成人头条 to resolve challenges and boost efficiencies for its enduring fleet of Black Hawk helicopters.
Through a partnership between the U.S. Army Aviation and Missile Command and 成人头条 State University, researchers at the National Institute for Aviation Research (NIAR) will create a virtual model of a UH-60L Black Hawk helicopter. Researchers will completely disassemble the airframes and capture a 3-D scan of each structural part, creating a virtual model 鈥� or digital twin 鈥� of the workhorse of Army aviation.
As a first step in this endeavor, an operational Black Hawk helicopter and a separate fuselage began an 800-mile journey Tuesday from Corpus Christi Army Depot in Texas to 成人头条, Kans.
鈥淭his opens a new door to aviation maintenance and sustainment,鈥� said AMCOM Commander Maj. Gen. Todd Royar. 鈥淲e welcome a new partnership with 成人头条, while fortifying our existing relationships across the Army aviation enterprise.鈥�
This is the first Army aircraft to enter a larger military effort with NIAR for legacy aircraft sustainment.
鈥淭his is a unique opportunity to bring a game-changing technology to the sustainment and logistics fields,鈥� said Maj. Sam Gray, Program Manager for the Strategic Capabilities Office.
The Sikorsky UH-60 Black Hawk helicopter entered Army service in 1979, replacing the UH-1 Iroquois 鈥� also known as the Huey helicopter. The UH-60 Alpha model was the first to enter the fleet, which was followed by the more advanced Lima and Mike models.
The Lima model of the Black Hawk helicopter has been out of production for 15 years, so most of its technology is at least that old, with some parts dating back 40 years. The digital twin opens the door to acquire parts that are out of production while building the capacity to use advanced techniques, such as additive manufacturing, to produce components.
Many industries have turned to digital-twin technology to create and improve opportunities to visualize, analyze and predict performance. The technology provides 3-D replicas of everything from buildings, trains, and air conditioning systems to including human body parts to test scenarios and ultimately boost the equipment鈥檚 performance.
鈥淭he intent is to enable readiness across the Army and the UH-60 fleets in the joint service and the applicable foreign military sales environment,鈥� Royar said. 鈥淎t the same time, we generate new opportunities to provide parts that are obsolete, low-volume or small quantity. The result is reduced operation and sustainment costs.鈥�
Among the driving factors for digital-twin technology is easing the sustainment effort to keep the Black Hawk helicopters flying over the next decades. As with other enduring military systems, the Army is often dependent on a single-source provider or faces challenges in obtaining certain parts. In turn, potential manufacturers must rely on 2-D drawings, many with changes and updates, that make it difficult to interpret, bid or produce the part.
鈥淐ertain low-use or low-volume parts don鈥檛 receive any bids from vendors,鈥� Royar said. 鈥淲hen we need those parts, we need the opportunity to get them in the system quickly 鈥� not the two-plus years it sometimes takes right now.鈥�
With future sustainment in mind, the endeavor to create a digital twin of the UH-60L connects NIAR experts with the Army and Sikorsky 鈥� the original equipment manufacturer 鈥� to convert all legacy 2-D drawings into 3-D parametric models.
鈥淭he intent of the UH-60L program is to demonstrate the application of this technology in fleet sustainment operations to increase threat timelines and operational readiness, reduce the cost of documentation, and increase sustainment affordability,鈥� said John Tomblin, senior vice-president for Industry and Defense Programs and NIAR executive director. 鈥淭he program will also allow the Army to maintain, and in some cases, increase, the size of the current functioning fleet.鈥�
成人头条 has conducted teardown investigations for the Department of Defense (DOD) for the past 15 years and has been performing digital-twin programs with the commercial industry over the last decade. In 2018, it began digital-twin work for the DOD, and disassembly of the Air Force鈥檚 B-1 bomber begins this summer.
The Strategic Capabilities Office has been working with 成人头条 and NIAR to improve fleet sustainment efforts, aimed at increasing readiness by leveraging advanced technologies, including the digital twin. Additional efforts are underway to leverage robotics and machine learning to improve repair time of different components, which pose potential readiness risks to the operational forces. SCO鈥檚 recent ventures in modernizing sustainment and life-cycle management capabilities for DOD platforms demonstrates the critical importance of integrating modern technologies into supply, logistics, and maintenance operations.
鈥淥ur goal is to develop a prototype capability which will transition into not just existing platforms within the Department of Defense, but identify the digital engineering requirements for future platform development,鈥� Gray said. 鈥淚t will be of great benefit to the Army if we can reduce sustainment costs and increase readiness for the UH-60L.鈥�
To ensure the digital twin can support future airworthiness activities, AMCOM is working with the Combat Capabilities Development Command Aviation and Missile Center鈥檚 (CCDC AvMC) Systems Readiness Directorate, which uses drawings, structural reports and physical checks to evaluate airworthiness of ongoing modifications to the UH-60L.
鈥淭he digital twin offers significant opportunities for improving the efficiency of airworthiness assessments and the potential to streamline evaluation and modifications from a fit and maintenance perspective,鈥� said Douglas Denno, CCDC AvMC鈥檚 lead for coordinating actions on the digital-twin effort. 鈥淭his is a thrilling opportunity to bring these key elements of technical data for the Army鈥檚 utility workhorse into the digital age.鈥�
As the first step in this project takes place with the aircraft transport, NIAR鈥檚 Tomblin said researchers are excited to begin the program with the Army in support of the UH-60 Black Hawk helicopter.
"The ability to provide support to the warfighter and increase readiness is a primary objective of this program, and we hope the results of this study can impact future maintenance and sustainment for this aircraft for decades to come,鈥� Tomblin said.
The collaborative effort of this project also includes the helicopter鈥檚 original manufacturer. Dina Halvorsen, Sikorsky program director for Army and Air Force Sustainment, said Sikorsky is proud to be partnered with the U.S. Army and 成人头条 on this project.
"With a collective focus to improve supply availability and readiness on the Lima platform, this initiative serves as a unique learning and discovery opportunity for all parties involved 鈥� particularly on how these next-generation technologies and processes work and how we can apply our findings from this effort to maximize the sustainment capability of both our existing and future fleet," Halvorsen said.
Beyond resolving supply-chain issues, the virtual technology will also improve maintenance issues. Repetition and exposure are the best ways to grow skills in mechanics and technical inspectors. But training and repetitive work on operational aircraft has the propensity to cause maintenance issues.
鈥淒igital-twin technology provides a virtual environment that facilitates the crawl, walk, run training philosophy that enables Soldiers to develop confidence in a simulated environment before performing the task on an actual aircraft,鈥� said AMCOM Command Sgt. Maj. Mike Dove. 鈥淰irtual environments enable a task to be taught through distance learning with the subject matter expert thousands of miles away.鈥�
The project to create a digital twin and ultimately a catalog of the UH-60L parts, brings academic and industry partners into a collaboration that includes the Office of Secretary of Defense Strategic Capabilities Office, several Army organizations, including AMCOM, Army Futures Command and Program Executive Office-Aviation.
鈥淚t takes this team of teams鈥� approach that will benefit not just the military but also academia and industry,鈥� Royar said. 鈥淎s we embark on this effort, I recognize the hard work being done between and across organizations, and I鈥檓 excited about the great opportunities it means for all interested parties and, ultimately, for aviation readiness.鈥�
