Afrl Downed Airman Recovery System, Daniel Cornia, James Bennett, Matthew Halton, Matthew Bennett, Brandon Haws, Tyson Compton, Jacob Needham, Daniel Spreier, Thory Van Dyke Jan 2020

Afrl Downed Airman Recovery System, Daniel Cornia, James Bennett, Matthew Halton, Matthew Bennett, Brandon Haws, Tyson Compton, Jacob Needham, Daniel Spreier, Thory Van Dyke

Mechanical and Aerospace Engineering

For the 2020 Air Force Research Laboratory design competition, teams were challenged to develop a system to assist Combat Search and Rescue (CSAR) in recovering a downed pilot in contested waters.

In the event of a pilot ejecting from their aircraft, a GPS beacon notifies CSAR of the pilot’s approximate location. During the rescue operation, a swimmer from a CSAR crew enters the water and assists the isolated person (IP) to use rescue equipment.

The current procedure exposes an additional person to hazards and increases IP extraction time. The additional required personnel and setup time increases mission risk.

Autoliv Flexible Windshield Reaction Surface, Perry Simpson, Jacob Bowman, Joshua Christensen, Ethan Moore Jan 2020

Autoliv Flexible Windshield Reaction Surface, Perry Simpson, Jacob Bowman, Joshua Christensen, Ethan Moore

Mechanical and Aerospace Engineering

Summary: Currently Autoliv is testing airbags against a flat steel plate. Testing against a steel plate doesn’t provide accurate airbag rebound data. Autoliv also does most of the development in series with automotive companies. They do initial designs but cannot get accurate tests until test vehicles are built.

Problem: Create a fixture that will bend a surface to replicate the curvature of any windshield desired resulting in more accurate airbag rebound data.

Why: Solving this problem will result in higher accuracy and precision in airbag performance systems. The new test fixture will provide a better representation of how the airbag …

Peridynamic Approaches For Damage Prediction In Carbon Fiber And Carbon Nanotube Yarn Reinforced Polymer Composites, Forrest E. Baber Jan 2020

Peridynamic Approaches For Damage Prediction In Carbon Fiber And Carbon Nanotube Yarn Reinforced Polymer Composites, Forrest E. Baber

Theses and Dissertations

Aerospace structures are increasingly utilizing advanced composites because of their high specific modulus and specific strength. While the introduction of these material systems can dramatically decrease weight, they pose unique certification challenges, often requiring extensive experimental testing in each stage of the design cycle. The expensive and time-consuming nature of experimental testing necessitates the advancement of simulation methodologies to both aid in the certification process and assist in the exploration of the microstructure design space.

Peridynamic (PD) theory, originating from Sandia National Lab’s in the early 2000’s, is a nonlocal continuum-based method that reformulates the equation of motion into an …
