The Air Force Special Operations Command (AFSOC) has driven the requirement and technology development of expendable, air-launched, Small Unmanned Aircraft System (SUAS) for the past six years. As the Air Force lead command for SUAS, AFSOC intends to use this capability to extend the range of on-board sensors, see below the weather, track multiple targets, increase target acquisition accuracy and provide direct support to ground teams. ...Today, state of the art technology for Group 1 (0-20 lbs) and Group 2 SUAS (21 - 55 lbs), provides approximately 25 - 60 minutes of endurance with conventional lithium ion / lithium polymer batteries. ...This paper presents a notional concept of employment for expendable air launched SUAVs coupled with a relevant example of state-of-the-art SUAS technology. The end goal will highlight realistic technology requirements for industry to develop an optimized system engineering design in the next two years that combines current cutting edge technology (i.e. super-capacitors, nano/micro-fuel cells, hybrid solutions and traditional batteries solutions) with industry safety standards for effective mission accomplishment.

The big boys go for plastic While it is true that the latest developments in advanced alloy manufacturing techniques can deliver structures and components that meet all the product requirements that aerospace primes need for new aircraft, there can be no escaping the fact that there is now an unstoppable momentum building up for the plastic airplane.

This specification covers the engineering requirements for producing brazed joints in parts fabricated from steels, iron alloys, nickel alloys, cobalt alloys, and copper alloys by use of silver alloys, and the properties of such joints. This procedure has been used typically for joints requiring high strength up to 400 degrees F (204 degrees C), but usage is not limited to such applications.

Touch-less control coming to cars Use of proximity and gesture-recognition systems in auto cockpits could rise fifty-fold within a decade. Forming a strong bond Multi-material vehicles are becoming more prevalent as automakers attempt to reduce vehicle weight and boost fuel efficiency. Selecting the proper adhesive is critical when bonding dissimilar materials. SAE 2014 World Congress preview special section: 'Creating New Possibilities' Host company Hyundai and Tier 1 Strategic Partner, Delphi, established "Creating New Possibilities" as the theme for this year's premier engineering event taking place April 8-10 in Detroit's Cobo Center. This special Congress preview section uncovers some of those possibilities, featuring insights from the event's executive leadership; details of a Delphi/Hyundai advanced engine program; highlights from the technical program in the areas of powertrain, materials, testing and simulation, electronics, interiors, and body/chassis; and more.
