It was at the Paris Air Show in 2011 that Sensichips, an Aero Sekur company (Hall 1 F294), announced it would be developing low-power, microchip-based sensor systems for the aerospace and defence sectors. Applications would include integrity monitoring, robotics and early identification of CBRN (chemical, biological radiation and nuclear) hazards.
A novel means of adding surveillance sensors to the C-130 quickly and with minimum modification is on display here at the Dubai Air Show.
According to a leading supplier of advanced microelectronics, design engineers in the defense industry should follow the automotive industry and be more willing to adopt commercially available technologies.
Canada’s National Research Council has won a patent on “an active and adaptive rotor-blade control system called Smart Spring,” which is designed to reduce the noise and vibration when rotor blades interact with the vortices shed by the tip of the preceding blades. Previous engineering approaches, according to NRC, have attempted to alter the varying aerodynamic load on the blades to reduce the onset of this vibration.
Researchers at the Birck Nanotechnology Center in Purdue’s Discovery Park and at the Sadeghi mechanical engineering laboratory have developed tiny wireless sensors resilient enough to survive the harsh conditions inside jet engines.
As the aircraft fleet ages and the number of in-flight material fatigue incidents climbs, a professor at the University of Missouri-Columbia says he has found a new and reliable method of identifying potentially dangerous cracks in aging aircraft.
Shirley, N.Y.-based Naasco Northeast Corp. (Booth No. 2238) recently received FAA approval for the overhaul and repair of Hartman A-1077 series relays, which are used on a variety of fixed- and rotary-wing aircraft and had previously been regarded as unrepairable.
