A Turbine For Christmas?
Small Turbine Engines Ready To Start Production...
Earlier this year, a Pennsylvania company called Affordable Turbine Power attracted some attention when they turned up at air shows with a turbine-powered RV-4 and said they would soon be selling their little engines to the experimental market. The company now has changed its name to Innodyn, and is also flying a turbine-powered RV-6. President Chuck Nearhoof told AVweb on Friday they are on track to start production of the turbines next month, with first deliveries in February.
Each of the four models weighs less than 188 pounds and delivers a range of maximum power from 165 to 255 hp, at costs ranging from $26,500 to $34,500. Nearhoof says they have a "substantial number" of orders to fill. For now, they are focused on the experimental market, with no timeline for developing a certified engine. "Certification is not a short-term goal, but it is a long-term goal," Nearhoof said.
...With Patented Fuel Technology...
Nearhoof said the fuel system uses a patented technology called "pulse width modulation" to control fuel flow to the engine. The system not only reduces operating and purchase costs, but also simplifies the use of the turbine. "This is light years beyond FADEC," Nearhoof said. The engine spins at 61,000 rpm and the computer that controls the fuel flow can make three decisions for each rotation. "It gives new meaning to the term 'full authority,'" Nearhoof said. The company is now working with the Defense Advanced Research Projects Agency (DARPA) on a test regime to determine the efficiency of the system, and Innodyn is not talking about fuel flow till those results are in.
At Sun 'n' Fun, in April, the company was reporting 13.3 gallons per hour in the RV-4. "We [are] completing assembly on sophisticated equipment to precisely determine fuel flow versus horsepower," the company says now on its Web site. "Until we have completed this detailed testing, we are hesitant to boast about our fuel flow rates. ... We will make this information available as soon as possible." The engine can burn diesel, kerosene or Jet A, and Innodyn says it expects to conduct tests with biodiesel in the near future.

I can see some cruise missiles and UAV's that can use this tech instead of the venerable Williams Turbojets.
