  Marines’ Presidential Helicopter Headed for IOC in July

  Posted on November 18, 2020 by Richard R. Burgess, Senior Editor ARLINGTON, Va. — The next generation of executive transport helicopter for the president of the United States is planned for Initial Operational Capability (IOC) in July 2021, a Navy spokeswoman said, but the decision of when to place the aircraft in service will be determined by the White House. The VH-92A, built by Sikorsky Aircraft Corp., a Lockheed Martin company, was selected in 2014 to replace the VH-3D and VH-60N helicopter fleet used to transport the president and other government executives. Six VH-92As were ordered in 2019. Followed by six more in February 2020. Total inventory will be 23 VH-92A aircraft, comprised of 21 operational fleet aircraft and two test aircraft. The presidential helicopter fleet is operated by Marine Helicopter Squadron One, based at Marine Corps Air Station Quantico, Va., with a detachment at Joint Base Anacostia-Bolling in Washington. “Government testing to validate system performance and prepare for Initial Operational Test and Evaluation is progressing on schedule and will support an Initial Operational Capability (IOC) planned for July 2021,” the Navy spokeswoman said. “The VH-92A will enter service post IOC at the determination of the White House Military Office.” https://seapowermagazine.org/marines-presidential-helicopter-headed-for-ioc-in-july/

  BAE Systems wins $148.3M Army contract to upgrade M88A1 vehicles

  ByEd Adamczyk Oct. 9 (UPI) -- BAE Systems announced a $148.3 million contract with the U.S. Army on Wednesday to upgrade M88A1 heavy-lift vehicles. A total of 43 vehicles will be rebuilt with increased power, maneuverability and survivability features to increase their configuration to M88A2 Heavy Equipment Recovery Combat Utility Lift System, or HERCULES, status. The Army intends to acquire 933 such vehicles -- with the upgraded M88A1s, it will have 914. "The HERCULES is an invaluable vehicle for the Army's recovery missions," said Dennis Hancock of BAE Systems. "We are proud to support the Army's recovery needs and we will continue to work alongside the Army to provide upgraded solutions as their missions and requirements change." Twenty-eight feet long and carrying a crew of three, the M88A2's specialty is the recovery of tanks mired to different depths, its capability in removing and installing tank turrets and power packs, and its ability to upright overturned heavy combat vehicles. The main winch on the M88A2 can move 70 tons, compared to the M88A1's 56 tons, allowing it to recover a 70-ton M1A2 Abrams tank. The upgraded vehicle can also be anchored for earth-moving purposes to prepare a recovery area and can refuel Abrams tanks from its own fuel tanks. Work on the program will be conducted at four BAE facilities in the United States, with deliveries scheduled to start in February 2021. https://www.upi.com/Defense-News/2019/10/09/BAE-Systems-wins-1483M-Army-contract-to-upgrade-M88A1-vehicles/5411570639391

  Army, Uber will partner on silent rotor technology for UAVs

  By: Charlsy Panzino The Army is partnering with Uber to create safer, more lethal unmanned aerial vehicle missions. The new effort between the Army Research Laboratory and the rideshare company, announced on Tuesday, aims to create silent rotor technology. The goal is to reduce the noise caused by traditional UAV rotors. “When UAVs are doing an [intelligence, surveillance and reconnaissance] mission, they're out there collecting or observing to collect intelligence or to do surveillance,” Jaret Riddick, director of ARL's Vehicle Technology Directorate, told Army Times after the announcement. That mission is hampered, however, when the adversary can hear the UAV coming, Riddick said. “They know a certain noise in the distance means a certain type of operation is underway,” he said. “When you can do that with the advantage of not being detected ... it changes how you execute a mission.” Uber Elevate, under which the air taxi side of the company falls, is interested in noise-reduction technology because its vehicles would be operating in dense urban areas. Since Uber is a technology company, ARL will build the UAVs for testing the technology. One kind of technology Uber is looking at to solve the noise problem is the idea of having stacked rotors on a vehicle that spin in the same direction. Traditionally, UAVs have stacked rotors that spin in opposite directions. “When those rotors are spinning in opposite directions, they create a type of turbulence that contributes to noise in the operation,” Riddick said. “By having them spin in the same direction and adjusting their position to one another, research has shown that using this technique can offer advantages in performance while reducing the noise compared with traditional operations.” One of these performance advantages is more lift capability, he said. Last year, Uber announced the Dallas-Forth Worth area as its first location for flight demonstrations in 2020, and Riddick said Uber will collaborate with ARL-South researchers in Austin. Uber and ARL-South will build the infrastructure needed for testing, Riddick said, adding that progress will be checked every six months. “Uber is proud to be partnering with ARL on critical research on flying vehicle innovations that will help create the world's first urban aviation rideshare network,” Eric Allison, head of Uber Elevate, said in a news release. “Our first jointly-funded project will help us develop first of its kind rotor technology that will allow for quieter and more efficient travel. We see this initial project as the first of many and look forward to continued collaboration with the lab on innovations that will make uberAIR a reality.” https://www.armytimes.com/news/your-army/2018/05/08/army-uber-will-partner-on-silent-rotor-technology-for-uavs/
