Software Aids Design of Ares V Composite Shroud Structure

NASA’s Ares V space launch vehicle makes significant use of composites, and during flight, the shroud of the Ares V will separate into four petals to release the Lunar Lander. In the design of the structure, the aerodynamic pressure on the shroud is resolved into internally distributed forces. A combination of two software packages — HyperSizer structural sizing software and Abaqus FEA (finite element analysis) software from SIMULIA (Providence, RI) — was used to model and simulate this process.

Battery Will Provide Backup Power for Space Shuttles

International Battery is building a battery prototype for NASA that will provide backup power in support of the space shuttle program. NASA is interested in the company’s largeformat, high-energy-density prismatic cells that provide advanced energy storage, as well as their Battery Management System (BMS). The BMS is specifically designed for large-format cells and provides increased safety through individual cell monitoring and continuous cell balancing. The entire system is being deployed as an uninterruptible power supply (UPS) to maintain backup power for critical ground operations.

Smart and Intelligent Sensors

Rocket engine testing is the primary mission for Stennis Space Center. Test stand facilities include the B-1/B-2 complex built for the Apollo Program, which is now used to test the RS-68 engine. A number of smaller test stands are available for testing components and lower thrust rocket engines. A-3 is a new test stand under construction that will have the capability to simulate high-altitude conditions. For each test article, the customer expects to receive highquality measurements to support their engine design, validation, and certification requirements. Making these measurements requires hundreds or thousands of sensors.

Infrared Zoom Moves Toward the Mainstream

For many years, infrared vision was limited to government and laboratory applications, but the picture is rapidly changing. With the cost of thermal cameras decreasing, military, aerospace, and scientific applications have expanded and the world of infrared has exploded with innovative new uses for law enforcement, surveillance, commercial, and even consumer applications.

NASA Portable Hyperbaric Chamber Technology Finds Home on Earth

NASA has signed a patent license agreement with OxyHeal Medical Systems of National City, CA to improve the medical community’s access to hyperbaric chambers used to treat many medical conditions and emergencies. OxyHeal will develop new products based on technologies NASA originally developed for space. Hyperbaric chambers create an environment in which the atmospheric pressure of oxygen is increased above normal levels. The high concentrations of oxygen can reduce the size of gas bubbles in the blood and improve blood flow to oxygen-starved tissues.
