Structural properties and cost of fiber reinforced polymers (FRP) are highly dependent on manufacturing techniques and material selection. The proposed work defines Innovative Composite Engineering’s (ICE) existing capabilities and identifies a path to successfully producing FRP cylindrical structures. A partnership between ICE and Oregon State University (OSU) will couple ICE’s decades of exp ...

Army Special Operation Forces (ARSOF) play a critical role in our nation’s safety and security, often acting as a force multiplier in small unit tactics. Critical within ARSOF, Multi-purpose Canines (MPCs) attached to ARSOF handlers serve as a critical component to mission success. However, an inability to communicate with MPCs out of line of sight (LOS), with specificity and without detection, ...

Gun barrels are subjected to wear and erosion from the hot propellant gases and high loads from the passage of projectiles. Sustained fire duration and rate of fire are largely limited by barrel thermal considerations, since the heat buildup in the barrel can cause rounds to fire prematurely (cook-off) or weaken the barrel and cause catastrophic failure. A cost effective solution of using a wear r ...

THE USE OF COMPUTER CODES THAT SIMULATE FLUID FLOWS IS BECOMING INCREASINGLY IMPORTANT IN THE DESIGN OF AIRCRAFT COMPONENTS. THE CURRENT STATE OF THE TECHNOLOGY OF NUMERICAL SIMULATION OF VISCOUS FLUID FLOWS IS SUFFICIENT FOR DEVELOPING ENGINEERING TOOLS FOR FLOW ANALYSIS OF VARIOUS TYPES OF COMPLEX THREE-DIMENSIONAL FLUID FLOWS. OF PARTICULAR INTEREST ARE FLOWS WITH AERODYNAMIC BODIES PERIODICALL ...

THE PROPOSED PROJECT ADDRESSES THE NEED FOR A SYSTEM TO DEPLOY EXPLOSIVES UNDERGROUND. THE SYSTEM WOULD BE BASED ON A GUIDED HORIZONTAL BORING TOOL CAPABLE OF MAKING EXCAVATIONS UP TO 400 FEET IN LENGTH AT DEPTHS UP TO 7 FEET. THE TOOL USES PRESSURIZED FLUID JETS TO CUT THROUGH A WIDE VARIETY OF SOIL TYPES. THE BORING TOOL COULD BE USED TO EITHER DROP AN EXPLOSIVE DEVICE AT A DESIRED LOCATION OR T ...

BY APPLYING ADVANCED CONCEPTS IN LIQUID CRYSTAL TECHNOLOGY A DYNAMIC, IMAGING QUALITY, NONPOLARIZING, NEUTRAL DENSITY FILTER CAN BE CONSTRUCTED WHICH WILL VARY TRANSMITTED LIGHT INTENSITY OVER A FULL RANGE OF NEARLY 0 TO 100%. THIS DEVICE WOULD POSSESS A SWITCHING SPEED ON THE ORDER OF ONE MILLISECOND AND COULD BE FABRICATED AT LOW COST OVER A VERY LARGE RANGE OF SIZES.

THICK FIBER-REINFORCED COMPOSITES WILL BE OBTAINED AND EVALUATED USING AN ADVANCED ULTRASONIC INSPECTION METHOD TO CHARACTERIZE THE MATERIAL FOR CRACKS AND DELAMINATIONS, POROSITY AND DENSITY VARIATIONS. THE ADVANCED ULTRASONIC INSPECTION METHOD IS BASED UPON SYNTHETIC PULSE TECHNOLOGY, WHICH WAS ORIGINALLY DEVELOPED FOR RADAR APPLICATIONS. A SHORT, HIGH ENERGY, BROADBAND PULSE IS REPLACED WITH A ...

THE PURPOSE OF AN AIR FLIGHT SENSOR SUBSYSTEM IS TO DETECT THE SIGNATURE OF FLIGHT CONDITIONS AFTER A PROJECTILE HAS BEEN SAFELY FIRED. THIS INFORMATION, WHEN COMBINED WITH OTHER CHARACTERISTICS OF PROJECTILE FIRING, SUCH AS ACCELERATION, PROVIDES POSITIVE INDICATION WHEN IT IS SAFE TO ARM THE WARHEAD. WE PROPOSE TO BUILD THE FLIGHT SENSOR SIGNAL PROCESSING AS A SINGLE, CUSTOM INTEGRATED CIRCUIT. ...

MECHANICAL G-SWITCHES ARE PRESENTLY AVAILABLE THAT SENSE WHEN THE ACCELERATION EXCEEDS A SPECIFIED VALUE. CONTACT RESISTANCE IS A PROBLEM EVEN WITH NEWLY FABRICATED MECHANICAL G-SWITCHES. MECHANICAL CONTACTS ARE ALSO SUBJECT TO SWITCH BOUNCE AND DAMAGE DURING THE INITIAL SHOCK OF IMPACT. SILICON DESIGNS HAS DEVELOPED A PROCESS FOR BUILDING MICROMECHANICAL SENSE ELEMENTS ON THE SURFACE OF A SILICON ...
