NASA and Industry Create Mid-Infrared Detector

NASA Goddard scientist Xiaoli Sun and his industry partner, DRS Technologies (Dallas, TX), have created the world’s first photon-counting detector sensitive to the mid-infrared wavelength bands — a spectral sweet spot for a number of remote-sensing applications, including the detection of greenhouse gases on Earth, Mars, and other planetary bodies as well as ice and frost on comets, asteroids, and the Moon.

A Tale of Tails

Tests were conducted recently by Boeing and NASA to answer the question: What if reducing the size of an aircraft’s tail could lead to more efficient air travel? The tests, focused on a technology called active flow control, are part of the Boeing ecoDemonstrator program. Active flow control is a technology that could result in a tail that is 17% smaller. This would reduce drag by about 0.5%, and would also reduce the tail’s weight, both of which cut an airplane’s fuel use and carbon emissions.

Editor's Choice: August 2015

NASA is developing the next generation of radiators using a composite that combines low density, high thermal conductivity, and high strength. A scalable process was developed that incorporates nanoparticles into magnesium that forms a high-strength, high-thermal-conductivity nanocomposite. Other applications for this technology are consumer electronics, automobile components such as brake systems, drill bits, mining equipment, and corrosion-resistant coatings.

Custom 3D Printers Revolutionize the Space Supply Chain

Additive manufacturing technology could enable future astronauts to build any part or piece needed on long-duration missions. A spaceflight crew has to bring with it everything it will need over the course of its journey. In space travel, not only is payload capacity at a premium, but objects carried into space also must be made to withstand the g-force and jarring vibrations of liftoff.

Servo Motors Help Launch Vehicles Optimize Fuel

Servo motors MICROMO (the FAULHABER Group) Clearwater, FL 800-807-9166 www.micromo.com Space Exploration Technologies (SpaceX) builds economical launch vehicles like the Falcon 9 to carry a range of payloads into orbit. One way to control cost is by optimizing fuel burned during launch to minimize waste. The SpaceX team ensures top performance with the help of a special fuel-trim valve, powered by servo motors from MICROMO. Rockets like the Falcon 9 and Falcon 1 at SpaceX burn a fuel known as RP-1, a highly refined form of kerosene that must be mixed with oxygen in order to burn. On the launch vehicle, 4" pipes run from tanks of RP-1 and liquid oxygen (LOX) to combine prior to entering the combustion chamber. RP-1 fuel won’t burn without oxygen, but as long as oxygen is present, the two do not need to be combined in a precise ratio. The problem is that if the ratio of LOX to RP- 1 varies from the optimum mix, either the oxygen will run out before the fuel, or the fuel before the oxygen. Once combustion stops, the material left becomes dead weight, turning from propellant to liability. To ensure this doesn’t happen, the fuel-trim valve adjusts the mixture in real time.

Design and Engineering of Process Plants Based on the “Lego Principle”

Users can add automation modules or switch them off in line with requirements. Festo Corporation, Hauppauge, New York Manufacturers in the process industries need to adjust to smaller batches and different types of product in the same plant. Plants based on the “Lego principle” are designed and engineered precisely to the respective task, whether for the production of a specific product in units per time unit, or for the throughput of a specific substance in a quantity per time unit. The mechanical design of the plant as a whole is geared towards meeting specifications and guaranteeing the required performance data over the projected lifecycle of the plant. The corresponding automation is carried out using management systems comprising process-specific (control) components, operating and monitoring stations, as well as engineering stations. The entire process is centrally controlled by a single management system.
