Ignition of rocket motors can be performed using low-volt firing components, but MIL-STD-1901A requires mechanical isolation for safety. While traditional safe & arm devices are available, they are relatively large and heavy. Recent progress in MEMS has developed miniature safe & arm devices for low-cost munitions such as 40MM grenade and airburst munitions. The Black Hills Nanosystems team has ...

ABSTRACT:The need for a natural language query capability for DoD regulations is identified. A technical solution based on artificial intelligence, cognitive computing, and natural language query technology is presented. In Phase I, various techniques will be investigated, and one or more solutions will be developed and tested. In Phase II, the down-selected technologies will be refined and built- ...

ABSTRACT:Specialty elastomers, such as hydrogenated acrylonitrile-butadiene rubber (HNBR) and fluoroelastomer (FKM), are widely utilized as high performance seals in numerous aerospace vehicles and components. The elastomer sealing industry and its products are primarily based on a limited pool of feedstocks that were last advanced in the 1970's. Using current technology, elastomeric seals must b ...

"The overall objective of the proposal is to improve performance of polymer matrix composite materials for cryogenic tank applications. The specific objectives of the program are:1. Determine the effect of cryogenic exposure on PMCs, particularly on the interphase region.2. Examine failed composite cryogenic tanks at the nanometer-level and higher to understand failure mechanisms.3. Develop ...

"The objective of this Phase II proposal is to develop a hand-portable waterless decontamination system based on Reactive Nanoparticle Technology to address chemical and biological threats. Currently fielded chemical warfare decontamination technologieseither rely on harsh oxidants (such as bleach) or logistically complicated bulky, equipment (such as high temperature pressure washers). An ideal ...

"SemiSouth proposes a proprietary technology involving the passivation of one type of shallow acceptor impurity to achieve precision compensation of the opposite type of shallow donor impurity. This Phase I feasibility demonstration represents aninnovative breakthrough in deep-level-free semi-insulating (SI) buffer layers for high-performance, economical silicon carbide radio-frequency (RF) MEtal ...

SiC JFET technology for control IC's in space based systems enable the possibility of temperature-tolerant, rugged, radiation-hard circuit operation. Additionally, it offers the possibility of combining with SiC power devices, a high level of integration,reduced parts count, reduced cost and weight in satellite systems. SemiSouth Laboratories, Inc. plans to transfer critical JFET IC technology d ...

Ultrasonic motors are novel devices that operate based on the piezoelectric effect. A "smart material" piezoceramic (Lead Zirconium Titanate, PZT) ring is excited by electrical signals and generates a traveling surface wave. The traveling surface wave drives a rotor through a toothed stator. These motors have several distinct advantages: low profile, high torque at low speeds, quick response, inse ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...
