  • With the youngest B-52 turning 56 this year, Boeing looks at updating the big bomber. By John Likakis First flown in 1952, the B-52 entered service with the U.S. Air Force in 1955. Production of the big eight-engine bomber continued for only 7 years after that, with the last B-52 coming off Boeing’s assembly line in October 1962. In what has to be one of aviation’s most astounding design successes, Boeing’s big bomber continues in service m...

  • by Donna J. Kelly The U.S. Army’s Future Vertical Lift (FVL) program aims to replace legacy helicopters with new, improved vertical lift aircraft able to rapidly perform a wide range of missions across greater distances than ever before possible. As you read this, major defense contractors, including Bell, Boeing, Lockheed Martin, and Sikorsky, along with hundreds of other manufacturers and suppliers, are building demonstrators of these vastly superior aircraft. The FVL program has set n...

  • The long-delayed Advanced Pilot Training Competition finally takes off. by James Wynbrandt By year’s end, the U.S. Air Force is expected to select the winner of its Advanced Pilot Training (T-X) competition. This selection will end the long and delayed search for a replacement for the venerable Northrop T-38 Talon, the Air Force’s primary jet trainer of more than half a century. The U.S. Air Force plans to order 350 of the new trainers, intended to prepare pilots to fly fifth...

  • The Latest in Deicing Techniques By Tracy Martin In-flight airframe icing has been a problem since the 1930s, when planes could fly fast enough and high enough for ice to form on the leading edges of wings and other surfaces. Even when there was no noticeable ice on an aircraft before takeoff, airmen discovered how quickly icing could occur in flight, with potentially dangerous effects. Although the nominal freezing point of water is 32 degrees Fahrenheit (0 degrees...

  • The Military Prototype that Launched the Civilian Jet Age By Patrick J. Walsh From a single voice in a corporate boardroom to the screech of jet engines powering a huge airframe into the western sky, Boeing’s early 1950s development of the 367-80 prototype created a distinctive soundtrack for one of the great industrial success stories in American history. Known within Boeing simply as the “Dash 80,” the 367-80 was the culmination of 5 years of corporate self-evaluation...

  • By Hank Hogan It could be up, up, and away for biofuels when it comes to military aviation. But to realize that potential, challenges have to be overcome, chief among them economics. Aviation biofuels — or sustainable alternative jet fuels, as advocates call them — must be cost competitive with other fuels, a tough task given current low oil prices. Vendors also have to ramp up production, while satisfying stringent military specifications. That requires substantial and economically risky...

  • Ongoing developments in innovative materials improve aerospace components, simplify manufacturing, and reduce costs. By KAREN WILHELM, ABD Online New high-performance materials continue to make jet engines and related components of modern-day aircraft lighter in weight, stronger, and, in some cases, more effective. In addition to these benefits, related efficiencies — from parts manufacturing to the performance of the aircraft — also can result ...

  • By DONNA DOLEMAN, Engine Air Magazine "The CFM56 is an eminently reliable engine," Graeme Peppler accurately pointed out in the fall 2008 issue of Engine Air. Even so, with nearly 19,000 CFM56 engines flying today and approximately 400 million cumulative flight hours logged, members of the CFM56 family require not only routine maintenance but also the occasional special repair. In addition, with an unprecedented number of units in service, operators always are seeking bet...

  • Preparations for the Joint Multi-Role Technology Demonstration are Underway By Donna J. Kelly Igor Sikorsky (1889–1972) once said that the helicopter is “probably the most versatile instrument ever created by man. It approaches closer than any other to fulfillment of mankind’s ancient dreams of the flying horse and the magic carpet.” The next generation of rotorcraft in the works right now will provide even more vertical magic to military crews performing di...

  • All About Helicopter Batteries, Present and Future By Tracy Martin Rotary-wing aircraft and automobiles do not have all that much in common, except for the fact that they both use an on-board battery. The job a battery performs in a car or truck is simple: starting the engine and providing power to accessories, such as the lights or power windows, when the engine is not running. By contrast, batteries used in helicopters are used to start engines or au...
