  • Optical and Acoustical Measurement of Ballistic Noise Signatures

    Abstract: Supersonic projectiles in air generate acoustical signatures that are fundamentally related to the projectile’s shape, size, and velocity. These characteristics influence various mechanisms involved in the generation, propagation, decay, and coalescence of acoustic waves. To understand the relationships between projectile shape, size, velocity, and the physical mechanisms involved, an experimental effort captured the acoustic field produced by a range of supersonic projectiles using both conventional pressure sensors and a schlieren imaging system. The results of this ongoing project will elucidate those fundamental mechanisms, enabling more sophisticated tools for detection, classification, localization, and tracking. This paper details the experimental setup, data collection, and preliminary analysis of a series of ballistic projectiles, both idealized and currently in use by the U.S. Military.
  • RD20 fosters collaboration

    With scientists, engineers and other professionals spread across seven laboratories and multiple fields sites across the country, the U.S. Army Engineer Research and Development Center (ERDC) network is vast. But last week, ERDC hosted a virtual symposium – RD20 – with the goal of further connecting researchers scattered in various laboratories and locations throughout the country to enhance the organization’s ability to solve the nation’s toughest engineering challenges.
  • ERDC’s Cold Regions Research and Engineering Laboratory breaks ground for climatic chamber building

    The U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL), along with U.S. Sen. Maggie Hassan, and U.S. Army Corps of Engineers (USACE) New England District broke ground together for CRREL’s new Climatic Chamber Building Oct. 16 at the Hanover, New Hampshire, campus. The Climatic Chamber Building will serve as a Material Evaluation Facility. The facility will provide a critical means to examine and test extreme cold-weather environments to develop and validate Army field materiel, which is required for Soldier and unit readiness.
  • ERDC’s Cold Regions Research and Engineering Laboratory builds Climatic Chamber Facility

    The U.S. Army Engineer Research and Development Center (ERDC) announced July 9, 2020, that the Cold Regions Research and Engineering Laboratory (CRREL) was awarded an Unspecified Minor Military Construction Authority contract to build a Climatic Chamber Facility on the Hanover, New Hampshire, campus.
  • ERDC’s Cold Regions Research and Engineering Laboratory awarded construction contract for new climatic chamber facility

    On July 9, 2020, the U.S. Army Engineer Research and Development Center announced that the Cold Regions Research and Engineering Laboratory (CRREL) was awarded an Unspecified Minor Military Construction Authority (UMMCA) contract to build a climatic chamber facility on the Hanover, New Hampshire, campus.
  • ERDC researchers study arctic sea ice

    The U.S. Army Engineering Research and Development Center’s Cold Regions Research and Engineering Laboratory (CRREL) collaborated with the U.S. Navy during the annual Sea Ice Dynamics Experiment (SIDEx) from February through March 2020 by predicting potential breaks in sea ice.
  • ERDC inventors earn patent for sensor planning software

    Inventors at the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory (CRREL) recently received a patent for sensor planning software tools designed to assist the U.S. Soldiers’ need to identify effective placement locations for sensors to accomplish their mission. Led by Research Physical Scientist Dr. David “Keith” Wilson, the research team, consisting of CRREL’s Signature Physics Branch, received the patent for their “System for Modeling Intelligent Sensor Selection and Placement” in July 2019.
  • ERDC Soldiers serve in the fight against COVID-19

    Although the vast majority of employees with the U.S. Army Engineer Research and Development Center (ERDC) are Department of Defense civilians, the select few U.S. Army Soldiers assigned to the ERDC are making a significant impact during the COVID-19 pandemic. Since March 2020, Soldiers from across the ERDC have deployed around the country to aid in the fight against the disease, many mobilizing to “hotspots” to confront the unique challenges of fighting an unseen enemy.
  • Cold Regions Research and Engineering Laboratory announces closure of child development center

    The Cold Regions Research and Engineering Laboratory (CRREL) announced June 5 that the child development center currently located at the laboratory in Hanover, New Hampshire, is scheduled to permanently close Sept. 15.
  • Answering the Call

    In late March 2020, Army 1st Lt. Eoghan Matthews, a Soldier assigned to the U.S. Army Engineering Research and Development Center’s (ERDC) Cold Region Research and Engineering Laboratory (CRREL), received a call. The instructions were cryptic but direct: “Pack a bag, and be ready to go somewhere in the Northeast.”
