Advancement in space exploration necessitates deep throttling of liquid cryogenic rocket engines. Both lunar and Martian robotic and human exploration require engines that can be deep throttled,can start and restart, have a long life, and require minimal maintenance. An engine that is capable of deep throttling at low...

As NASA moves towards developing technologies needed to implement its new Exploration program, studies conducted for Apollo in the 1960s to understand the rollover stability of capsules landing are being revisited. Although rigid body kinematics analyses of the rollover behavior of...

The first step in implementing the capability to test sensitive launch vehicle instruments in a combined environment has been completed. The test environment consists of specific vibration spectra induced under sustained Gs, using NASTAR’s ATFS-400 centrifuge. Fixtures allow mounting...

In order to perform human-like movement, an actuator is placed at each degree of freedom (DOF) in a humanoid robot. Additionally, these actuators must be packaged in an arrangement that approximates human structure and appearance. In this innovation, a rotary actuator assembly incorporates a brushless DC motor, a gear...

Senior Operations LLC Metal Bellows (Sharon, MA) offers the DELTA P high-pressure bellows seal for use in injection valve applications. It is capable of withstanding high external system pressures, while maintaining low differential pressure across the edge-welded bellows. This feature enables the bellows to be designed with thinner...

ams AG (Raleigh, NC) has introduced the 47 Series magnetic position sensors featuring a technology capable of producing accurate angle measurements of rotors spinning at high speed. The sensors feature DAEC™ (Dynamic Angle Error Compensation), a patent-pending technology that eliminates the measurement error attributable to...
