What is STUDROLLER technology? Cross Roller Guides

NB SLIDE WAY cross roller guides use precision rollers to provide stable, non-recirculating linear motions in precision stages, inspection equipment, semiconductor manufacturing, and more. At the heart of all NB cross roller bearings is the STUDROLLER mechanism, which eliminates the cage-creep phenomenon that, over time, can create deviances in cross roller retainer performance. NB cross roller guides equipped with this system are more accurate and better performing than any other comparable products on the market today. High acceleration and faster cycle times are possible in any orientation.

NASA's tiltrotor sets wind-tunnel record for high-speed proprotors

What kind of aircraft combines the speed of an airplane with the vertical take-off and landing capabilities of a helicopter -- and could be your traffic-beating air-taxi ride of the future?

A tiltrotor aircraft.

NASA's Tiltrotor Test Rig is being used to improve tiltrotor technology for future aircraft designs.

The Tiltrotor Test Rig, also known as TTR, is a new, full-scale proprotor test system undergoing testing in the biggest wind tunnel in the world: the U.S. Air Force's National Full-Scale Aerodynamics Complex or NFAC, located at NASA's Ames Research Center in Silicon Valley.

TTR was developed to fill gaps in understanding of proprotor performance at higher speed and power conditions than have been previously tested.

The TTR set a speed record in August 2018, achieving 314 mph, or 273 knots -- the highest airspeed test condition ever achieved by a proprotor of this size in any wind tunnel. And this maximum speed was limited by the wind tunnel, not the test rig!

For the test, a 26-ft-diameter research proprotor (seen at top of photo) was installed on the TTR inside the 40- by 80-ft wind tunnel. As of October 2018, data has been collected to include 35 combinations of airspeed and angle of air blowing at the rotor, from edgewise (helicopter mode) to straight-on (airplane mode), simulating flight conditions from vertical takeoff through conversion to high-speed horizontal flight. Testing included control variations, motor power checks, effects of temperature, and vibration tests.

The tests are part of NASA's research for 21st century tiltrotors and other advanced rotorcraft concepts, which require improved capability for wind-tunnel tests of full-scale proprotors. The TTR is providing critical data for validation of state-of-the-art design and analysis tools for vertical-lift vehicles. The recent tests demonstrate that the new test rig is "go for green" to provide proprotor performance measurements at previously unseen levels of power, speed, and accuracy.

The TTR is a partnership with the U.S. Army and Air Force. Bell Helicopter Textron of Fort Worth, TX (now Bell), and Triumph Aerospace Systems of Newport News, VA (Calspan Systems Corp.), designed and manufactured the TTR and supporting equipment under NASA contract.
