Preventing Premature Part Failures with Electropolishing

Design engineers in the aerospace industry are constantly challenged to improve fit and function of components used in commercial and military aircraft. Parts used in these aircraft must withstand high-stress, corrosive conditions with long-term use. They also must meet highly demanding cycle life specifications.

3 Key Benefits: Better Corrosion Resistance, Fatigue Life, Part Integrity

Electropolishing has become a common metal finishing process used in the aerospace industry to help improve the overall quality of metal components. These components come in many forms including high-performance fasteners, fittings, nozzles, housings, and welded assemblies. In order to maintain reliable performance, these components must be precisely manufactured and have an impeccable surface finish that is free of burrs and other contaminants.

Optical Interconnect Design Challenges in Space

More and more aerospace applications are incorporating fiber optics technology into their designs due to its many advantages over copper. The thinner fiber solutions provide higher speed over a longer distance, are more reliable, offer higher noise immunity and, in many cases, lower the cost of ownership. Additionally, for the same diameter, fiber can pack more data than copper. Fiber is faster than the category 5 and 6 copper cables, approaching the speed of light (31% lower). For copper, pushing the speed beyond 1G is a challenge, but for fiber 10G is quite common. Copper is limited by distance. Usually, signal degradation with copper will occur after about 90 meters (2.7 km maximum for custom systems), while fiber can achieve more than 1.5 km without a problem and can deliver over 80 km depending on transmission signal quality.

New Products: August 2018 Aerospace & Defense Technology

Barometric Pressure Sensor

Bosch Sensortec (Reutlingen, Germany) has introduced a new high performance barometric pressure MEMS sensor, the BMP388. The BMP388 delivers outstanding altitude stabilization in drones, where accurate measurement of barometric pressure provides the essential altitude data for improving flight stability and landing accuracy. The new barometric pressure sensor is part of Bosch Sensortec's comprehensive sensor solution for drones, which includes the BMI088 Inertial Measurement Unit (IMU) for accurate steering and the BMM150 geomagnetic sensor for the provision of heading data.

Designing a High-Speed Decoy Unmanned Aerial Vehicle (UAV)

Drone aircraft and their uses have been evolving quickly, supported by a great deal of ongoing research. One area of increasing interest is the decoy drone, designed to mimic the radar and heat signature of an actual aircraft. These drones are intended to confuse or mislead anti-aircraft defense systems. If operating as designed, one or more drones are launched from an actual aircraft as it enters airspace monitored by anti-aircraft systems. The system picks up the signature of the drones and attacks them while the actual aircraft can be hidden with the swarm of drones.
