All about the ceramic matrix composites in GE's adaptive cycle engine for F-35 fighter jets
GE has provided details of using ceramic matrix composites (CMCs) in the XA100 adaptive cycle engine for the Lockheed Martin F-35 jet fighter. The new engine can switch between high-thrust and high-efficiency modes. The CMC super materials have helped create an engine "with 25% better fuel efficiency, 10%+ better thrust, and significantly more thermal management capability." CMC components can withstand more heat, weigh far less than metal ones, and are stronger and longer lasting.

Top Tech Tip: Tips to avoid resonance problems in stepper motors
If you need a low-cost motor with simple operation, stepper motors are a solid choice -- they can be driven, step by step, without an encoder or Hall sensor for rotor position feedback. However, according to the motor experts at Portescap, the straightforward design that makes stepper motors so popular can also lead to resonance problems in certain conditions.

How a NASA engineer created the modern airplane wing
Once dubbed "the man who could see air," NASA engineer Richard T. Whitcomb used a combination of visualization and intuition to revolutionize modern aviation -- by turning the shape of the airplane wing on its head. Today, nearly every commercial airplane bears the marks of Whitcomb's several innovations, which include the development of winglets on wing tips.

Image - What is a C-Flex Pivot Bearing?
What is a C-Flex Pivot Bearing?
It's a flexure-based bearing utilizing internal flat crossed springs, capsuled in a cylindrical housing, to provide precise rotation with low hysteresis and no frictional losses. The C-Flex bearing will offer indefinite life when used within its rated load and rotation values. Applications include Medical, Industrial, and Aerospace.

Pilot recounts tales of SR-71 Blackbird
The SR-71 reconnaissance aircraft flew missions around the globe from 1966 to 1998 at speeds above Mach 3 and altitudes of 85,000 ft or more. Although its many contributions to national security will never be fully revealed to the public, the Skunk Works marvel holds world aviation records for its speed and altitude. In this interview with former SR-71 pilot Col. Buzz Carpenter, you'll hear a first-hand account of the aircraft's power and majesty.

What's a magnetic GHOST fastener?
PEM® GHOST™ Fastening Technology from PennEngineering uses a fully concealed pinch-lock mechanism to create a secure and sleek lock with zero visible evidence of disassembly once engaged. Using a magnetic release tool on the concealed fastener actuates the internal components, unlocking the pinch-lock grip and instantly releasing the pin from the fastener. From automotive interiors to access control systems, this clever fastening tech is adaptable to many applications.

Hevi-Rail Linear Bearings enable telescopic racking for heavy loads
Shipping containers face a constant struggle to optimize storage space and accessibility within a confined area, as well as keep accurate inventory and streamline loading/unloading. A recent task was straightforward: Design a racking system that maximized organization and storage for cargo. In collaboration with a leading designer in storage containment, PBC Linear recommended implementing their high-load-capacity Hevi-Rail linear bearing solution, which was installed in a specially designed assembly that could handle cantilevered loads.
