Customized Goniophotometer System Tests High Intensity Obstruction Lights

Hughey & Phillips (H&P), Urbana, OH Hughey & Phillips (H&P) designs and manufactures flashing and steady state anti-collision lighting used on above-ground obstructions like communication towers, antennas, buildings, wind turbines, grain elevators, smoke stacks, bridges and other man-made structures that are potential collision hazards for aircraft. Used as either standalone fixtures or as part of integrated systems, these low, medium, and high intensity lighting devices illuminate obstructions to aerial navigation as specified by the FAA, FCC, ICAO, DGAC of Mexico and Transport Canada. The required light output intensity of H&P’s products increases with altitude - the higher the elevation, the greater the required output intensity.

Embedded Servo Drive Boosts Speed of Packaging Lines

Pfankuch Machinery, based in Ahrensburg, Germany, is a leading manufacturer of friction feeder systems for inserting leaflets and products into sales packaging. An embedded smart servo drive from Metronix (part of the Apex Tool Group in Sparks, MD) has allowed Pfankuch to increase the speed of its latest friction feeder — the SmartFeeder — by 50% while also doubling the positioning accuracy. This offers a massive gain in productivity for the many users of this type of packaging equipment in markets including pharmaceutical, and food and beverage processing. At the same time, the new embedded drive minimizes the hardware costs of the upgrade for Pfankuch, because the drive was adapted for the application, providing a stripped-down product suitable for OEM integration that eliminates numerous expensive components.

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.

Water Impact Simulation Ensures Safer Landing for NASA Astronauts

The water landing of a craft like the Orion Crew Module is a very complex and changeable event, subject to the dynamics of the vehicle’s structure and sub-structures, such as its heat shield and atmospheric and water conditions. To maintain the spacecraft’s structural integrity and increase safety of the crew, a clearer understanding of the dynamic loads generated during water impact was required.
