Temperature control has been a major concern during High Velocity Oxygen Fuel (HVOF) processing since it was originally utilized in the aerospace industry. Typically, temperature must not exceed 300oF to prevent heat damage/ tempering of the substrates on steel alloys, and even lower temperature requirements for aluminum and titanium alloys. These problems have prevented USAF depots from usage of ...

ABSTRACT: Over the last twenty years the United States has become dependent on space technology for communications, precision tracking and many other applications. Globalization of the worlds economy, which has also dramatically increased over the past twenty years, has resulted in this same dependence in industrialized and developing nations around the world. As a result of these trends, the s ...

ABSTRACT:The reduction of aerodynamic/hydrodynamic noise caused by violent turbulence is of strategic importance to many military systems. These include modern fighter jets, unmanned weapons with sensitive electronics, and surface and underwater vessels. For all these systems, aerodynamic or hydrodynamic noise can produce unacceptable levels of operational loads or acoustic vibrations, or be detri ...

ABSTRACT:It is widely recognized that near surface residual stresses play a significant role in fatigue performance. Tensile residual stresses are of concern because they accelerate fatigue crack initiation and fatigue crack growth relative to what would occur in the absence of residual stress. Compressive residual stresses, on the other hand, have the opposite effect and can be used to improve fa ...

ABSTRACT:We have investigated different strategies for removing the surface porosity from out-of-autoclave (OOA) composites.It was found that a release layer on the aluminum tool with a microstructure similar to that of woven Teflon release plies was effective at reducing the porosity.These structures allow trapped gases to escape during curing, so that they do not generate bubbles/pores in the la ...

ABSTRACT: Peel ply, sanding and atmospheric plasma treatment have been examined as alternative methods for the surface preparation of bismaleimide carbon-fiber composites prior to bonding. It was found that atmospheric plasma treatment of the composite surface decreases the water contact angle from 822 to 202. X-ray photoemission spectroscopy of the treated composites revealed a 91% increase in s ...

ABSTRACT: Warfighters need to be able to trust the systems on which their lives depend. Cases include an individual human trusting an individual computer, an individual computer trusting a server or network to which it is connecting, a server or network trusting an individual computer connecting to it, and (new here) one network trusting another with which it is inter-connecting. Military airborn ...

ABSTRACT: The proposed technique employs a variety of sensors that combine data to form a comprehensive picture of a situation of interest. The goal is to increase the effectiveness of military surveillance by giving a more complete, integrated picture of situations to enable a quicker response while eliminating errors from potential failures of individual sensors. In Phase I of this program, AS& ...

ABSTRACT: To address the Air Force need for a liquid shim application system for automated advanced fighter assembly, Physical Optics Corporation (POC) developed the Interpolated Liquid Shim Application System (ILSAS), which has demonstrated the ability to apply highly precise amounts of liquid shim that achieve perfect squeeze-out of cured material. Studies with the system demonstrate a 300% red ...

ABSTRACT: Toyon in partnership with FLIR EOC, proposes to leverage recent advances in large-format hybrid (CMOS/InGaAs) focal plane arrays and composite focal plane array technology to develop a low-cost, SWaP (Size, Weight, and Power) optimized, high resolution imaging system capable of providing wide area persistent imagery within the near infrared (NIR) to short wave infrared (SWIR) spectrum. ...
