Freeform optics is a recent, emerging and developing field to meet the increasing demands created by the high performance and ultra-compact optical imaging systems that underpin consumer and medical applications, such as mobile phones, head mounted displays, and ultrathin endoscopes. Additive manufacturing will be an ideal method to prototype freeform optics if surface quality specifications can b ...

There is a need for a lightweight, high-performance, insulation to protect the internal systems in hypersonic vehicles. A passive thermal protection system (TPS) design would be simple and reliable. As designs evolve, there is a need for TPS insulation materials that can be additively manufactured. Our Phase I approach will additively manufacture pre-ceramic scaffolds that are used to create low d ...

ABSTRACT: Three dimensional (3-D) printing is a robust and facile means for rapidly producing complex geometry prototype electrical insulators. Unfortunately, these techniques are limited towards producing insulators suitable for low voltage applications (e.g. electric field applications < 20 KV/mm ) given current 3-D printed material shortcomings coupled with possible introduction of macroscopic ...

Hydronalix, a world leader in maritime robotic rescue systems will team with the Materials Department Rapid Prototyping Center at Oklahoma State University to perform this program. The Phase I program will focus on the study to identify, develop, and qualify use of rapid prototyping 3D Printing technologies for reducing the cost to manufacture Navy sonobuoys by at least 10% but most likely a much ...

Direct Energy weapons in the form of High Energy Lasers (HEL) and High-Power Microwaves (HPM) for use in air and space-based platforms, continue to be technologically challenged, mostly due to equipment size, which translates into a need for higher energy and power density components.  High voltage pulse capacitors are a key and often a critical component of different pulse power systems.  The P ...

A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer surface of the bracket will be made of rubber and the inner core will be made of 9255 spring steel, ...

COMPUTATIONAL FLUID DYNAMICS (CFD) CODES HAVE BECOME IMPORTANT DESIGN AND ANALYSIS TOOLS FOR ENGINEERS, PARTICULARLY IN THE AEROSPACE INDUSTRY. CFD CODES, HOWEVER, ARE SEVERELY LIMITED BY THE COMPUTING RESOURCES OF PRESENT-DAY SUPERCOMPUTERS. IT IS ESTIMATED THAT A THREE ORDER-OF-MAGNITUDE INCREASE IN COMPUTER SPEED IS NECESSARY FOR PERFORMING PRACTICAL ENGINEERING VISCOUS-FLOW ANALYSES OF FULL AI ...

ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

Lightning Ridge Technologies advances the state of the art of Controlled Reception Pattern Antennas (CRPAs) for rotorcraft by developing an adaptive beamsteering technology to significantly mitigate hostile jamming while estimating and cancelling GPS signal variations that plague rotorcraft operations. These variations include but are not limited to rotor interference, manufacturing variability an ...
