Sikorsky Vows to Break `Pure Helicopter' Sound Barrier Sikorsky is challenging the conventional thinking that a rotorcraft cannot be built to exceed 200-kt. cruise speed without sacrificing the abilities that make a helicopter unique and valuable. "Today's top cruise speeds of 150-170 kt. are only incrementally faster than they were decades ago" due to the limits of conventional rotor systems...June 1, 2005

Helicopters as Commodities? One of the more intriguing comments made about the U.S. presidential helicopter decision is that the choice of airframe didn't really matter because helicopters have become commoditized and only exist to carry around their high-tech systems payloads. Another said the contract went to Lockheed Martin because its systems-integration expertise, in the final analysis, mattered much...June 1, 2005

I have more than 30 years of commercial helicopter flying in a utility role in some of the harshest environments Mother Nature has to offer. I...June 1, 2005

The Reality of Turbine Autorotations Fortunately, not many of us have real engine failures. We all should be practiced enough to know how to recognize and deal with one, so it should be no big surprise. Instinct takes over and we do what should come naturally. The problem is that, in a lot of turbine helicopters, what we've practiced and learned to judge things by is not always what happens. Unless the...April 1, 2005
