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.

Army selects top two Future Attack Reconnaissance Aircraft prototype design performers

The Bell 360 Invictus is one of two final contenders in the U.S. Army's Future Attack Reconnaissance Aircraft program competition.

 

 

The U.S. Army selected two performers executing under Other Transaction Authority for Prototype agreements for the design and testing of the Future Attack and Reconnaissance Aircraft (FARA) Competitive Prototypes to continue into phase two of the program.

The two vendors selected are Bell Helicopter Textron Inc. (Fort Worth, TX) and Sikorsky Aircraft Corp. (Stratford, CT).

The Army requires an aircraft capable of operating in a complex airspace and degraded environments against peer and near-peer adversaries with an advanced integrated air defense system. The current aviation fleet does not possess a dedicated aircraft to conduct armed reconnaissance, light attack, and security with improved standoff and lethal and non-lethal capabilities from a platform sized to hide in radar clutter and for the urban canyons of mega cities.

"Our focus is on delivering capability for our Soldiers at the speed of relevance," said Gen. John M. Murray, Army Futures Command commanding general. "We're doing that here -- providing opportunities for our industry partners to design, test, and build capability alongside our Soldiers to ensure that we win on a future battlefield."

"The Future Attack Reconnaissance Aircraft is the Army's number one aviation modernization priority and is integral to effectively penetrate and disintegrate adversaries' Integrated Air Defense Systems," said Dr. Bruce D. Jette, Assistant Secretary of the Army for Acquisition, Logistics, and Technology. "It will enable combatant commanders with greater tactical, operational and strategic capabilities through significantly increased speed, range, endurance, survivability and lethality."

The FARA CP solicitation structured the program into three phases: preliminary design; detailed design, build, and test; and prototype completion assessment and evaluation for entrance into production phase.

In April 2019, five OTAP agreements for the aircraft design, build, and test of FARA were awarded for phase one. The five industry performers were AVX Aircraft Co. partnered with L3Harris, Bell Helicopter Textron Inc., The Boeing Company, Karem Aircraft, Inc., and Sikorsky Aircraft Corp. (Lockheed Martin). Phase one ended when the government conducted an initial design and risk review assessment with each performer and selected these two performers to continue into phase two.

The project transitions into phase two now, as the two performers will complete detailed design, build, and test of their air vehicle solutions. This phase will end with a government flight test evaluation no later than the fall of 2023.

Bell Textron unveiled its entrant for the U.S. Army's FARA Competitive Prototype program in January 2020. The new rotorcraft, dubbed the Bell 360 Invictus, "combines proven low-risk technologies with advanced processes to deliver soldiers an affordable, agile, and lethal solution to win on the modern battlefield."

The Bell 360 Invictus design emphasizes exceptional performance using proven technologies to fulfill the Army's FARA requirements at an affordable cost and on schedule. One example is the Invictus' rotor system. This design is based on Bell's 525 Relentless rotor system which has been tested and proven at speeds in excess of 200 Knots True Air Speed (KTAS).

Sikorsky debuted its RAIDER X FARA concept copter at the end of 2019. It's a fast-flying, agile, and lethal compound coaxial helicopter that has been specifically designed for securing vertical lift dominance against evolving threats on the future battlefield.

RAIDER X can reach speeds of more than 250 knots (over 280 mph), almost double the speed of a conventional civilian helicopter, and is capable of flying in excess of 9,000 ft in 95 F heat. It can carry six troops and external weapons, and it aims to redefine helicopter flight during the 21st century.

Based on Sikorsky's Collier Award-winning X2 Technology, RAIDER incorporates the latest advances in fly-by-wire, flight controls, vehicle management systems, and systems integration. It also has retractable landing gear, active vibration control, a composite fuselage, active elevator and rudders, split torque transmission, and a rigid co-axial rotor system. These technologies enable the aircraft to operate at high speeds while maintaining the low-speed handling and maneuverability of conventional, single main-rotor helicopters.
