What are piezoelectric active shims?
Active shims, such as PIRest from Physik Instrumente, can readjust the gap between two components in a machine at any time with nanometer precision. Due to the piezo element's high resolution down to the nanometer range, active shims cover applications in classical mechanical precision engineering, as well as the alignment of optical components in astronomy, semiconductor manufacturing, and in materials research employing beam-line instrumentation.

Voice coil stages and actuators for precise motion
Because of their small dimensions, voice coil motors are often integrated in compact stages, actuators, and fast tip/tilt mirror platforms. These devices are driven by an electromagnetic motor consisting of a moving coil winding and a fixed magnet (the opposite is also possible). By precisely controlling the electric current in the coil, the magnetic force (Lorenz force) -- and thus, acceleration, velocity, and position -- can be varied very accurately.

Compact, low-noise gearboxes for high loads
With the GP56-N series, the Nanotec product line now also includes low-noise planetary gearboxes for brushless DC motors and stepper motors with flange size 56 and 60 mm. They are ideally suited for applications in medical devices and building automation. The helical toothing allows the teeth to mesh gradually, which results in a smoother transmission of forces so that vibrations and noise are reduced. Planetary gears and the ring gear consist of a high-quality, low-wear plastic, making the new gearboxes quieter than conventional, straight-geared metal gearboxes. Available in one- and two-stage versions in nine different reductions and varying output torques.
Gearless speed reducers with traction drive tech
Stock Drive Products / Sterling Instrument (SDP/SI) has introduced new speed reducers with traction drive technology. Featuring a gearless drive, these speed reducers are highly efficient and feature only six moving parts. They use engineered traction fluid to cool and lubricate, and they generate less heat than conventional drives. Years of development and testing have been invested in this new technology, resulting in a product featuring infinite ratios up to a ratio of 5:1, dramatic reduction of motor torque ripple, low vibration and noise level, and significantly less maintenance than a conventional gearbox.
Exploring Mars with miniature motors
When developing the high-resolution Panoramic Camera on the ExoMars Rover, engineers looked for motors that were extremely compact and could also deliver reliable and precise positioning for the camera-focusing mechanism. FAULHABER Stepper motors were selected for the job, as they precisely position objects with a resolution of 1280 steps per revolution without the need for a separate feedback system, and are more rugged and sturdy than conventional servo motors.

NASA begins work to build quieter supersonic passenger jet

The return of supersonic passenger air travel is one step closer to reality with NASA's award of a contract for the preliminary design of a "low boom" flight demonstration aircraft. This is the first in a series of ‘X-planes' in NASA's New Aviation Horizons initiative, introduced in the agency's Fiscal Year 2017 budget.
NASA Administrator Charles Bolden announced the award at an event Feb. 29 at Ronald Reagan Washington National Airport in Arlington, VA.
"NASA is working hard to make flight greener, safer, and quieter -- all while developing aircraft that travel faster, and building an aviation system that operates more efficiently," said Bolden. "To that end, it's worth noting that it's been almost 70 years since Chuck Yeager broke the sound barrier in the Bell X-1 as part of our predecessor agency's high-speed research. Now we're continuing that supersonic X-plane legacy with this preliminary design award for a quieter supersonic jet with an aim toward passenger flight."
NASA selected a team led by Lockheed Martin Aeronautics Company of Palmdale, CA, to complete a preliminary design for Quiet Supersonic Technology (QueSST). The work will be conducted under a task order against the Basic and Applied Aerospace Research and Technology (BAART) contract at NASA's Langley Research Center in Hampton, VA.
After conducting feasibility studies and working to better understand acceptable sound levels across the country, NASA's Commercial Supersonic Technology Project asked industry teams to submit design concepts for a piloted test aircraft that can fly at supersonic speeds, creating a supersonic "heartbeat" -- a soft thump rather than the disruptive boom currently associated with supersonic flight.
"Developing, building, and flight testing a quiet supersonic X-plane is the next logical step in our path to enabling the industry's decision to open supersonic travel for the flying public," said Jaiwon Shin, associate administrator for NASA's Aeronautics Research Mission.
Lockheed Martin will receive about $20 million over 17 months for QueSST preliminary design work. The Lockheed Martin team includes subcontractors GE Aviation of Cincinnati and Tri Models Inc. of Huntington Beach, CA.
The company will develop baseline aircraft requirements and a preliminary aircraft design with specifications, and provide supporting documentation for concept formulation and planning. This documentation would be used to prepare for the detailed design, building, and testing of the QueSST jet. Performance of this preliminary design also must undergo analytical and wind tunnel validation.
In addition to design and building, this Low Boom Flight Demonstration (LBFD) phase of the project also will include validation of community response to the new, quieter supersonic design. The detailed design and building of the QueSST aircraft, conducted under the NASA Aeronautics Research Mission Directorate's Integrated Aviation Systems Program, will fall under a future contract competition.
NASA's 10-year New Aviation Horizons initiative has the ambitious goals of reducing fuel use, emissions, and noise through innovations in aircraft design that departs from the conventional tube-and-wing aircraft shape.
The New Aviation Horizons X-planes will typically be about half-scale of a production aircraft and likely are to be piloted. Design-and-build will take several years, with aircraft starting their flight campaign around 2020, depending on funding.
