It is not uncommon for engineers to develop a new compound for maintenance or manufacturing purposes, but then find that they cannot control processes well enough to produce large enough batches to make it cost-effective. That was the case recently when the U.S. Air Force (USAF) developed a replacement material for tape around access panels on the B-2 bomber.

Lockheed Martin is drawing upon its experience in the practical use of advanced metals to make a number of significant improvements to the manufacturability and supportability of its three most important aircraft: the C-130J, F-22, and F-35.

Breaking the mold is the USAF’s newest X-plane, the Advanced Composite Cargo Aircraft (ACCA). Lockheed Martin will build the ACCA, which will be based on a Fairchild Dornier 328J regional jet that will have its aluminum mid/aft fuselage and empennage replaced by sections built of advanced composites.

Often an integrated circuit based on an older design is more valuable to satellite designers than a newer one. Imagine the consternation several years ago when Actel Corp. discontinued production of a pair of field-programmable gate arrays that have seen widespread acceptance in commercial and military satellites. All the major manufacturers let BAE know that they’d have a ready market if they were willing to restart the production line.

A variety of manufacturers have successfully shown how small, tactical, relatively low-cost UAVs can provide soldiers and marines on the ground with timely data on enemy positions. One of the keys to such programs is not the electro-optic/IR sensors through which data is collected, but the autonomous control systems that make such systems operable.

The emirate of Dubai in the United Arab Emirates operates one of the world’s most respected airlines, Emirates. Now it intends to re-create that success in the field of aircraft maintenance. The newly created Dubai Aerospace Enterprise recently completed its $1.9 billion acquisition of aviation service providers Standard Aero and Landmark Aviation.

Pratt & Whitney (P&W) claims it has developed more than 300 new repairs through the Scrap Avoidance and Value Engineering (SAVE) program, an initiative designed to repair or reuse engine parts that have been deemed unserviceable. Since its introduction in 2002, the program has saved customers more than $100 million, according to P&W.

The U.S. Department of Defense (DOD) expects to save hundreds of millions of dollars annually under performance-based logistics (PBL) contracts, where aerospace and defense contractors are paid to deliver operational readiness of weapons platforms rather than spare parts.

Article
Composite materials are working their way onto the engine as evidenced by the GEnx's composite case. France's Snecma is also making strides in finding new applications for composites on the engine—specifically for fan blades.

Article
The FAA has reached a major milestone on the Next Generation Air Transportation System initiative to modernize America's National Airspace System.

Article
NextGen is a mosaic of technologies that when meshed together will yield significant benefits in myriad areas. RNP, for example, leads to efficiencies that offer reduced fuel consumption and emissions.

Article
Several years ago, U.S. Air Force maintenance technicians at Tinker Air Force Base discovered that an additive designed to remove water from traditional JP8 jet fuel was unexpectedly causing paint to peel off the inside of B-52 fuel tanks. The main concern was that the paint chips could clog the fuel filter and cause an engine flameout.

Lasers such as the ones used by Vought on the 747-8 program are particularly effective at measuring components for reverse engineering, and are also adept at measuring large components such as wings that are too big to fit on a CMM machine.

Article
The 5000-psi hydraulic systems developed by Parker Aerospace for the Boeing 787 and Airbus A350 are significant developments in their own right, but they arguably take a back seat to other hydraulic technologies being introduced on the soon-to-be-in-service widebodies.

Article
Boeing has cited a worldwide shortage of aerospace fasteners as one reason it has delayed the flight-test program of its 787, which is now in development. One of the main reasons there are shortages today is fastener manufacturers were forced to consolidate their operations earlier in the decade when orders dried up during the last downturn.

Article
While the automotive industry and academia have dominated work in the area of autonomous vehicles in the past, most of the actual autonomously controlled vehicles that have been introduced in recent years have come from the military.

Article
Among the advances seen increasingly in robots used for aerospace manufacturing is the application of force control and material-thickness sensing.

Article
Machine manufacturers and operators have decades' worth of experience managing the chips that are produced in the process of cutting metal. That is not the case with the waste produced in the machining of composite parts, which presents a number of challenges that will only grow as airframers turn to a greater percentage of composites in their aircraft.

Article
The continued evolution of rapid manufacturing is dependent on two basic elements: processes and materials. Academia and industry are busy exploring improvements in both.

Article
Electrohydraulics are particularly suited to platforms where there is a high degree of coordination required between the propulsion and work functions, as well as those where functional complexity or repetition of task is more suited to an automated approach.
