Steering Toward the Future

Faced with rising fuel prices and growing environmental concerns, the automotive industry is reinventing itself — and simulation is playing a critical role. The global automotive industry faces incredible pressures today. The skyrocketing costs of traditional fuels — along with worldwide supply uncertainties — are forcing automakers to not only increase the efficiency of current fuels, but to explore new fuel sources and engine designs that will drive increased efficiency.

Thrusters Support Communications Satellite Launch

Monopropellant (hydrazine) thrustersAerojet RocketdyneSacramento, CA 916-355-4000 www.rocket.com Aerojet Rocketdyne, a GenCorp company, played a vital role in placing the second of three next-generation Tracking and Data Relay Satellites (TDRS-L) into orbit for NASA. In the second stage of launch, a single RL10A-4-2 engine ignited to place the TDRS-L into orbit, helped by 12 Aerojet Rocketdyne monopropellant (hydrazine) thrusters in four modules on the United Launch Alliance Atlas V Centaur upper stage, providing roll, pitch, and yaw control, as well as propellant settling burns during ascent. The RL10A-4-2 engine delivers 22,300 pounds of thrust to power the Atlas V upper-stage, using cryogenic liquid hydrogen and liquid oxygen propellants during its operation. ARDe, a New Jersey-based subsidiary of Aerojet Rocketdyne, provides the pressure vessels on the first and second stages of the launch vehicle. TDRS-L will use a single R-4D 100-lbf thruster for orbit insertion.

Product of the Month: The Objet500 Connex3 Color Multi-Material 3D Printer

Stratasys, Eden Prairie, MN, has introduced the Objet500 Connex3 color multi-material 3D printer, the first 3D printer to combine colors with multi-material 3D printing. It features triple-jetting technology that combines droplets of three base materials to produce parts with virtually unlimited combinations of rigid, flexible, and transparent color materials, as well as color digital materials, all in a single print run. Similar to a 2D inkjet printer, three different color materials (VeroCyan, VeroMagenta, and VeroYellow) are combined to produce hundreds of vivid colors. These color materials join the PolyJet photopolymer materials, including digital materials, rigid, rubber-like, transparent, and high-temperature materials, to simulate standard and high-temperature engineering plastics. The printer features six palettes for rubber-like Tango colors, ranging from opaque to transparent colors in various shore values.
