Abstract
Content
  • Electrifying Aviation: The Path to Decarbonizing the Skies
    /Electric aviation mirrors the early stages of the electric vehicle revolution
  • Advances in Military Avionics Technologies Create New Challenges for RF Test and Measurement
  • Plasma Electrolytic Oxidation: The Future of Lightweight Designs in Aerospace and Defense
  • Advanced RF Simulation Reduces Cost and Schedule Risk
  • Assure 5G NTN Performance Before Launch
    In the complex and quickly evolving 5G NTN landscape, simulating, emulating, and evaluating RF systems boosts mission success.
  • Qualification of Multi-Channel Direction Finding Radar Receivers in The Lab
  • Bullet Impact Testing of Ammunition and Explosives at Picatinny Arsenal
    A bullet impact (BI) test for evaluating the response of energetically loaded items has been established at the U.S. Army Combat Capabilities Command (DEVCOM) Armaments Center (AC) Explosive Development Facility.
  • Update on Machine-Learned Correctness Properties
    A novel method which has the potential for improving the U.S. Navy's ability to perform continuous assurance on autonomous and other cyberphysical systems.
  • Test Methods for Measuring High Temperature Tensile Properties of Subscale Specimen Geometries for Additively Manufactured Metallic Materials
    An overview of the state-of-the-art for subscale high temperature tensile testing of metallic materials.
  • Methodologies and Equipment for Measuring High Temperature Tensile Properties of Subscale Specimen Geometries for Additively Manufactured Metallic Materials (Continued)
    Editorial Note: With the growth in adoption of addititively manufactured materials across aerospace and defense manufacturing, we decided to include two parts of this Air Force Research Lab report.
  • Repeatability and Reproducibility of a Standard Test Method for Measuring Head-Supported Mass Properties
    During development of military helmets and HMDs, materiel developers need a valid and repeatable test methodology for measuring their mass properties. DEVCOM SC and USAARL reviewed existing mass properties measurement procedures and identified critical items to incorporate into a unified Army methodology.
