The limited availability of donor hearts for people with end stage heart failure has driven the condevelopment of mechanical circulatory support systems (MCSSs). MCSSs can be broadly classified intocontinuous flow systems. Pulsatile systems drive blood indirectly through blood pumps, resulting inThis disadvantage of these systems, however, is their relatively large size. Continuous flow systemssim ...

A radical, high performance system design concept for UAV missions is proposed. Its characteristics derive directly from propulsion and power generation capabilities inherent in microturbine technology under development at MIT. The proposed vehicle configurations is an oblate spheroid, giving a high package volume with sufficient fuel capacity for hover duration of about one hour. Thrust from m ...

Imaging spectrometers are a powerful new tool for performing hyperspectral measurements for remote sensing, environmental monitoring, and target detection and characterization applications. The major problem associated with hyperspectral measurements now, however, is not the technology for performing the measurements but rather the technology for analyzing and recording the high data rates genera ...

Micro Aerial Vehicle (¿AVs) will open up a wide range of new missions for the US Armed Forces, but also present a new set of technical challenges. The power and propulsion system will have a significant impact on the ultimate capabilities and range of missions of ¿AVs. While advanced battery technology can provide good propulsion performance for ¿AVs, miniature internal combustion engines can ...

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 ...
