New 22-mm brushless servo motor packs a punch

MICROMO has launched the brand new FAULHABER 2264 BP4 series brushless dc servo motor, which is ideally suited for handheld tools and devices such as motorized surgical instruments, grippers and robotics, advanced prosthetics, aerospace applications, and even for electric pruning shears and motorized screwdrivers. At 22 mm in diameter, 64 mm in length, and weighing only 140 grams, the 2264 BP4 series delivers 59 mNm of continuous torque and reaches speeds up to 34,500 rpm. These impressive power and performance characteristics are possible due to a new segmented winding of the coil, which also improves the overall efficiency of the motor.

New rodless pneumatic cylinder supports compact machine design

Aventics now offers a new product for applications where the basic variants just won’t do the trick, but high-performance cylinders are too powerful. The new RTC-SB slide bearing version rounds off the pneumatics specialist’s RTC range of rodless cylinders. At the heart of the RTC-SB (slide bearing) is its oval piston shape. In relation to its size, it offers a very high load capacity. As a result, engineers can draft even more compact machine designs. Equipped with a lubrication-free slide bearing, the cylinder is maintenance-free and resistant to water, chemicals, and dirt. The slide play is optimally adjusted at the factory. Max speed is 6.5 m/sec (21.3 ft/sec). Maximum stroke is around 6,000 mm (21.6 ft).

Revolutionary new high-pressure electric pump system

High Pressure Equipment Co. (HiP), a subsidiary of Graco, introduces the eTensifer pump, the first-of-its-kind high-pressure electric pump system. The plug-and-play pump simply plugs into a wall outlet -- no need for an air compressor like other high-pressure pumps on the market. The portable, lightweight (only 46 lb) eTensifier will deliver hydraulic/liquid pressures to 36,500 psi with a smoother flow rate from zero to full pressure and a quiet electric motor. SmartControl™ technology allows for two operational modes: a traditional pressure knob for standard jobs and an industry-first pressure test mode. Another first is the ProConnect™ quick-connect system that allows users to switch out the Sprague pump lower.

First engine assembled for DARPA and Boeing reusable experimental spaceplane

Aerojet Rocketdyne technicians complete final assembly on the first AR-22 rocket engine, shown at its facility located at Stennis Space Center. The engine was built for Boeing as part of the U.S. Defense Advanced Research Projects Agency Experimental Spaceplane program.

 

 

 

 

Aerojet Rocketdyne has completed assembly of its first AR-22 rocket engine built for Boeing as part of the U.S. Defense Advanced Research Projects Agency (DARPA) Experimental Spaceplane program. This new Boeing spaceplane, called Phantom Express, is intended to demonstrate a new paradigm for more routine, responsive and affordable space access.

Aerojet Rocketdyne's AR-22 engine, derived from the Space Shuttle Main Engine that was designed from the outset for reusability, is the main propulsion for Phantom Express. The fuel is Liquid hydrogen.

DARPA is collaborating with Boeing to fund development of the Experimental Spaceplane (XS-1) program. Once Phantom Express reaches the edge of space, it would deploy the second stage and return to Earth. It would then land on a runway to be prepared for its next flight by applying operation and maintenance principles similar to modern aircraft. [Boeing rendering]

 

 

 

 

"Phantom Express builds on our legacy of reusable space flight experience to provide the ability to quickly augment and replace on-orbit capabilities, which face an increasing array of threats from potential adversaries," said Eileen Drake, Aerojet Rocketdyne CEO and president. "Our immediate task is to demonstrate this rapid turnaround capability for this engine on the ground, paving the way for a demonstration program."

The AR-22 engine is capable of generating about 375,000 lb (170,097 kg) of thrust and was designed to fly 55 missions with service every 10 missions. This reusability feature makes the AR-22 ideally suited for Phantom Express.

The reusable, 100-ft-long Phantom Express spaceplane will take off vertically and land horizontally. The 24-ft-high vehicle will be equipped with an expendable second stage capable of placing up to 3,000 lb (1,361 kg) of payload into low Earth orbit. The spaceplace has a wing span of 62 ft.

"The aircraft-like operations of Phantom Express are an important factor in the rapid turnaround of this spaceplane," said AR-22 Program Manager Jeff Haynes. "Additionally, the engine has a hinged nacelle that makes it easier to access and inspect the engines for rapid turnaround."

Aerojet Rocketdyne assembled the AR-22 at its facility at NASA's Stennis Space Center in Mississippi. The engine will undergo a series of daily hot-fire tests at Stennis starting this summer to demonstrate its ability to support the high flight rates envisioned for Phantom Express. These tests will also provide valuable insight that will be used to refine Phantom Express flight and turnaround procedures, while also informing the design requirements for the new ground infrastructure that Boeing is developing for the flight program.
