| | Feature articles | 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.

 | Application Note: Landing-gear drop test
Landing-gear manufacturers use load cells to measure shock forces and fatigue ratings during quality-assurance examinations. FUTEK's LCA Family of miniature column load cells offers a robust miniature design for these high-capacity measurements. See how it's done.

 | Optimize mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.

 | Cool Tools: Digital oscilloscope tests motors for damaging shaft voltages
Industrial motors controlled by variable frequency drives (VFDs) are at risk of electrical bearing damage. The new AEGIS Shaft Voltage Tester Digital Oscilloscope makes it easier than ever to check in-service motors for damaging VFD-induced shaft voltages and head off bearing damage and costly unplanned equipment downtime. A complete package, the two-channel, full-function 100-MHz digital oscilloscope comes with a special conductive microfiber-tipped probe for exceptional shaft contact, a probe holder with magnetic base, and a compact carrying case.

 | Linear Motion: Mini voice coil actuators
H2W has built its smallest moving magnet voice coil actuator (NCM01-04-001-2IB) to date, with an outside diameter of 0.40 in (10 mm) and a length of 0.735 in (18.8 mm). It has a stroke of 0.10 in (2.5 mm) and generates a continuous force of 0.10 lb (0.45 N) and a peak force of 0.30 lb (1.35 N). It weighs just 0.20 oz (5.7 g). This actuator uses a hardened shaft and sliding contact bushing to ensure long life and is ideal for oscillatory motion -- particularly in a number of handheld applications. Moving magnet voice coil actuators have built-in bearings, so there is no need for the customer to add mass or complexity to their motion system to integrate a bearing, and there are no moving leads to worry about cable management.
