By Kimberly Hoodin Rowan University will lead a $14.5 million Department of Defense/Army Research Lab project to create new composite materials – and ways to process those materials – that will help modernize the Army and improve the safety of soldiers in the field. The project, titled “Advancing Structural Materials for Army Modernization Priorities via Direct-Write Approaches,” will be led by researchers from Rowan University teamed with PPG, Drexel University, Northeastern University and the University of Massachusetts Amherst to create new advanced composite and plastic materials and ways to process them. The project is driven by a cooperative agreement with the U.S. Army Combat Capabilities Development Command Army Research Laboratory. The team will work on developing innovative materials by using “cold-spray” advanced manufacturing technologies. The work will focus on polymers, starting with polystyrene, then move on to more advanced composite materials and systems, as designated by the Army. “The high particle velocity of cold spray enables rapid cure and adhesion of polymers. This should result in the fast and efficient production of high-performance composite parts or repair of parts,” said John La Scala, associate chief the ARL's Materials and Manufacturing Sciences Division and cooperative agreement manager for the research program. “Additionally, this novel manufacturing methodology is a layer-by-layer production of composites, which should reduce void and flaw content. This should improve strength and durability significantly, thereby opening the potential of using this manufacturing technique to prepare composites for extreme conditions, while replacing the current expensive manufacturing methods with a much more economical methodology.” Researchers hope to develop materials to be used for making military equipment stronger and lighter, soldiers more agile and vehicles more durable. Longer-term, the team sees the potential for use of the materials in the fields of civil aviation, automotive, health care and space exploration. “We will work to make materials more quickly, to make them better and easier to repair offsite and, importantly, onsite in the field,” Dr. Joe Stanzione, associate professor of chemical engineering at Rowan University said. “That includes everything from parts for tanks and jeeps, to usable tools, and helmets.” http://compositesmanufacturingmagazine.com/2019/08/rowan-university-project-will-develop-composite-materials-used-to-protect-soldiers/

A new generation of Combat Rescue Helicopter AirMed&Rescue's special correspondent Joetey Attariwala was one of a select few journalists invited to Sikorsky's Development Flight Center in West Palm Beach, Florida, to cover the roll-out ceremony of the US Air Force (USAF) new Combat Rescue Helicopter – the Sikorsky HH-60W, affectionately known as the ‘Whiskey'. It was there that he had the opportunity to see the aircraft firsthand and interview program executives from Sikorsky and the USAF. The USAF describes the mission of the Combat Rescue Helicopter (CRH) system as ‘one which provides Personnel Recovery (PR) forces with a vertical takeoff and landing aircraft that is quickly deployable and capable of main base and austere location operations for worldwide PR missions'. The CRH system activities may be required during any phase of a service / joint / coalition operation, across the full range of military operations, in any land or sea location, within the areas covered by the relevant defence planning scenarios. The aircraft will be self-supporting to the maximum extent practical; and an in-flight air refueling capability extends the combat mission range. The CRH system may conduct combat search and rescue (CSAR) airborne mission commander duties; and may also conduct other collateral missions inherent in their capabilities to conduct PR, such as non-conventional assisted recovery, national emergency operations, civil SAR, international aid, emergency aeromedical evacuation, disaster and humanitarian relief, counter drug activities, support for National Aeronautics and Space Administration flight operations, and insertion / extraction of combat forces. The CSAR and PR mission is currently being conducted by the HH-60G Pave Hawk, which over the past 30 years has seen extensive use around the world, most notably in the Central Command Area of Responsibility. The Pave Hawk platform has seen modernization over its lifetime; however, system add-ons have increased maintenance and support requirements over the years. Speaking to this point was General James Holmes, Commander of Air Combat Command, who said: “Over 90 per cent of our legacy airplanes – the HH-60G fleet – have sustained combat damage or structural fatigue over the 30-plus years they have been in service, and the current availability rate is well below the requirement.” With statistics like that, it is no wonder the HH-60W is a highly anticipated platform for the USAF. Introducing the Jolly Green II The HH-60W is a highly modified variant of the battle-proven UH-60M Black Hawk, with the ‘Whiskey' variant providing significant capability and reliability advancements over the HH-60G to better support the full range of combat rescue and other special missions. The HH-60W specification drives more capable defensive systems, vulnerability reduction, weapons, cyber security, environmental, expanded adverse weather sensor capabilities, and more comprehensive net-centric requirements. The CRH contract consists of the original Engineering and Manufacturing Development (EMD) award, which was issued on 26 June 2014, and five additional System Demonstration and Test Article (SDTA) aircraft options, which were awarded in January 2017. In all, the CRH program of record calls for 113 helicopters, of which nine are EMD / SDTA aircraft and 104 will be production aircraft. In addition to purchasing the aircraft, the contract includes development and fielding of the aircrew and maintenance training systems along with product support. https://www.airmedandrescue.com/latest/long-read/sikorsky-hh-60w-us-air-forces-new-combat-rescue-helicopter
