  • How and Why Supersonic Engines must be Perfectly Mated with Their Intakes By Donna J. Kelly Since every airframe is different, the design of each intake, also called an “inlet,” is unique and varied in its methods of achieving the precisely correct amount, speed, and flow of air entering the aircraft’s engine. It is of such importance that the marriage of intake and engine be perfectly harmonious that the original equipment manufacturer (OEM) of the airframe is responsible for...

  • How do leading parts and service providers stay ahead of market demands? By James Wynbrandt It is not enough to have the right part or offer the precise repair a customer needs. Today, aftermarket providers — whether original equipment manufacturers (OEMs), distributors, or maintenance, repair, and overhaul (MRO) service providers — aim to know what item or fix the customer will need and when they will need it, and then get it to them faster than it has ever been d...

  • 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...

  • The modernization of the RAFs Puma fleet proved many detractors wrong. Limiting upgrades to necessities rather thannice to haves resulted in an impressive extension to the models out-of-service date. By Andrew Drwiega Every nation wants to be armed with the newest and the best aircraft and equipment. A highly capable modern force not only contributes toward a nation’s military being an effective ...

  • The Sikorsky SH-3 Sea King By Patrick J. Walsh Searching the sky for some sign of the Sikorsky SH-3 Sea King — their helicopter — the crew of the USS Altair (AKS-32) waited eagerly. Then, they heard it, the sound of the rotors cutting the air, as the distinctive helicopter with the orange nose neared the flight deck on the ship’s fantail. As an underway replenishment stores ship responsible for supplying the U.S. Sixth Fleet in the Mediterranean,...

  • 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...

  • By HANK HOGAN, Engine Air Magazine This is a reprint of an article that appeared in the Summer 2012 issue of Engine Air Magazine. The latest incarnation of the world's best-selling plane, the Boeing 737 MAX, is slated to pass an important milestone this summer. At facilities in the United Kingdom and the United States, wind tunnel testing will confirm the plane's low- and high-speed performance, respectively, according to Michael Teal. Mr. Teal is Chief Project Engin...

  • 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...

  • Sikorsky’s CH-53K King Stallion is a new breed of heavy lifter, in ascension. By James Wynbrandt The airframe appears virtually identical, the model designation varies by just a single letter, and even their names are almost interchangeable. But the Sikorsky CH-53K King Stallion, now in development, is a breed apart from the CH-53E Super Stallion it is scheduled to replace, and represents major advances in rotorcraft performance, safety, maintainability, and desig...
