Mini medical motor with way more torque
Portescap's 22ECP35-2A brushless motor with integrated driver is the company's latest addition to its Ultra EC mini brushless DC motor line. This compact, 22-mm diameter motor is available in a length of 35 mm and offers almost 50% more continuous torque over similar motors without compromising on smooth operation and long life. The integrated motor drive is a good fit for applications such as respiratory and ventilation devices, infusion pumps, miniature industrial pumps, medical hand tools, and valve actuation.
Miniature linear guides simplify mounting in tight spaces
IKO's new LWLF2 linear motion rolling guide addresses the demand for device miniaturization with a compact, lightweight design that makes mounting easy in tight spaces. With an ultra-small 2.5-mm height dimension, it is designed with tapped rails for bottom mounting and stability. The LWLF2 guide is structured with two rows of balls that make contact with the raceway at four points to provide high stability and accuracy -- even in applications with varying load direction or complexity. Applications include robotics and grippers, semiconductor fabrication, life science, and aerospace.

NEMA 24 stepper motor with best-in-class power density
Permanent magnets between the stator teeth make Nanotec's SCB6018 with 60-mm flange a smooth-running -- yet powerful -- stepper. FluxFocus technology guides the entire magnetic flux into the stator teeth. This prevents flux leakage and provides more torque across all speeds. This motor generates a holding torque up to 3.6 Nm. Combined with a closed-loop controller, the SCB6018 is ideal for use in valves and textile or other applications that require rapid acceleration over a short distance.

NASA begins work to build quieter supersonic passenger jet
This is an artist's concept of a possible Low Boom Flight Demonstration Quiet Supersonic Transport (QueSST) X-plane design. The award of a preliminary design contract is the first step toward the possible return of supersonic passenger travel -- but this time quieter and more affordable. [Credits: Lockheed Martin]
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.
