The Air Force Research Laboratory, Space Vehicles Directorate (AFRL/VS), has developed a unique composite Payload Attach Fitting (PAF) shell design. Alliant Techsystems (ATK) and the Boeing Company, Huntington Beach, CA, have developed manufacturing processes and a shell design that incorporates an all-composite forward flange with transverse reinforcement (Z-pinning) at key locations to preven...

The direct numerical simulation (DNS) of heat transfer in a fully developed turbulent pipe flow with for various Prandtle numbers are performed to obtain statistical quantities such as turbulent heat flux, and temperature variance. Main emphasis is placed on Prandtl number effects on turbulent heat transfer in pipe flow. Probability density functions and joint probability density functions of v...

This paper discusses the development and implementation of a new ergonomic manual control system for a large construction manipulator. The manipulator consists of a 22 ton rough terrain hydraulic crane with a multifunction manipulator attachment. The combined device gives a single operator hydraulic control over eight independent joint axes allowing for dextrous positioning of large sections of...

We describe the design concepts of the modular humanoid robot Myon, which can be disassembled and reassembled during runtime. The body parts are fully autonomous in a threefold sense: they all possess their own energy supply, processing power, and a neural network topology which allows for stand-alone operation of single limbs. The robot has especially been designed for robustness and easy main...
