Design, Synthesis and Analysis of Loader Bucket, Boom and Linkages for Amphibious Infantry Combat Vehicle

Independent Researcher-Abhijit Kulkarni
Konecranes-Akhilesh Kulkarni
Published 2019-10-11 by SAE International in United States
Currently, for various military activities such as construction of bridges, digging trenches, construction of roads and clearing the area during landslides, separate unit of bulldozer for dozing operation and loader for loading operation is required. But the need is to develop a single unit which could perform both of these operations efficiently and simultaneously. The paper discusses about the development of dozer bucket mechanism as a single unit to perform dozing and loading operation and connected to the amphibious infantry combat vehicle. To develop the dozer bucket mechanism synthesis of mechanism (Linkages and Boom) has carried out and care has taken to fulfill the above stated functional requirement and satisfy the geometrical constraints. The synthesis of mechanism is done with the help of ‘CATIA’ software packages. The force calculation on various joints at the different position of mechanism has evaluated with the help of ’ADAMS’ software. The finite element analysis has done using software ’ANSYS’. The developed mechanism combines the dozing and loading operation and connected to the tracked vehicle.

SnowMicroPenetrometer Applications for Winter Vehicle Mobility

  • Magazine Article
  • TBMG-35361
Published 2019-10-01 by Tech Briefs Media Group in United States

The U.S. Engineer Research and Development Center (ERDC) Military Engineering Program on Remote Assessment of Infrastructure for Ensured Maneuver (RAFTER) Boreal Aspects of Ensured Maneuver (BAEM) identifies the need for modeling over-snow vehicle performance, as many factors related to vehicle setup and land surface condition contribute to vehicle efficiency. Accurately estimating snow macromechanical characteristics—such as elastic modulus, stiffness, and strength—is critical for understanding how effectively a vehicle will travel over snow-covered terrain.

Defeating Commercial Drone Threats with Open-Source SDR

Aerospace & Defense Technology: October 2019

  • Magazine Article
  • 19AERP10_06
Published 2019-10-01 by SAE International in United States

With the emergence of highly capable, low-cost, wirelessly controlled drones, bad actors can easily execute disruptive operations. Such incidents have created a need for drone defense systems that rapidly evolve with ever-increasing threat frequency and sophistication.

It's nearly impossible to look at technology news without seeing an article about drones. Whether detailing how Amazon wants to use drones to deliver packages or revealing amazing aerial video of drones following Olympic snowboarders, commercial drones are ubiquitous. Drone emergence has benefited many applications including sports broadcasting and wildlife preservation wilderness surveys. Offering powerful, intelligent software, drones are becoming less expensive and easier to use, with substantial operating range.

Waveform Synthesis for Shock Response Spectrum Replication, Applied to Ground Vehicle Component Testing

  • Magazine Article
  • TBMG-35354
Published 2019-10-01 by Tech Briefs Media Group in United States

The motivation for this work is to mitigate shock levels on vehicle components, through testing new designs of equipment. The objective is to generate a time history to perform shock testing on military and commercial ground vehicle components. The time histories are used to drive hydraulic actuators coupled to a test specimen.

Perspectives on Integrating Structural Health Monitoring Systems into Fixed-Wing Military Aircraft

Aerospace Industry Steering Committee on Structural Health
  • Aerospace Standard
  • AIR6245
  • Current
Published 2019-09-18 by SAE International in United States

This SAE Aerospace Information Report (AIR) is prepared for stakeholders seeking information about the evolution, integration, and approval of SHM technologies for military aircraft systems. The report provides this information in the form of (a) two military organizations’ perspectives on requirements, and (b) general SHM challenges and industry perspectives. The report only provides information to generate awareness of perspectives for military aircraft and, hence, assists those who are involved in developing SHM systems understanding the broad range of regulations, requirements, and standards published by military organizations that are available in the public domain from the military organizations.

Microturbine Propulsion for UAVs

Aerospace & Defense Technology: August 2019

  • Magazine Article
  • 19AERP08_03
Published 2019-08-01 by SAE International in United States

Seventy years ago, military aviation moved from reciprocating engines to vastly more reliable turbo jets and turboprops. Shortly after, the commercial air transport industry followed suit, enabling modern air transport. Today, virtually all large aircraft rely on turbine propulsion, yet small aircraft, both manned and unmanned, have not exploited the advantages of turbines for propulsion.
