THE OTHER WING by Darryl Phillips NASA's GENERAL AVIATION PLANS DON'T INCLUDE QUIET ENGINES - Feb 1995 Once each year, major federal agencies solicit proposals from small businesses on a wide variety of topics. In the 1994 cycle, NASA listed 108 topics. While I'm not a great believer in socialized research and development, I found one topic that was too good to pass up: "General Aviation Propulsion Systems... Proposals are invited for innovative concepts or integration of technologies in aircraft propulsion that are appropriate for use in general aviation aircraft. Objectives are to improve performance, safety and reliability, simplify operation, reduce maintenance and costs, and improve environmental compatibility (e.g. reduce community noise from aircraft operations). Areas of interest include the following: Simplified (single lever) power and/or airspeed controller systems. Automated engine performance monitoring systems. Innovative, alternative fuel engine concepts (e.g. rotary and diesel concepts).

Don Nolan-Proxmire Headquarters, Washington, DC August 3, 1996 (Phone: 202/358-1983) Lori Rachul Lewis Research Center, Cleveland, OH (Phone: 216/433-8806) RELEASE: 96-157 NASA INITIATES NEW GENERAL AVIATION PROPULSION PROGRAM NASA has announced a partnership with the FAA and the U.S. aviation industry for a new program that will address the critical need to improve affordability and performance of U.S. light general aviation aircraft propulsion systems. The General Aviation Propulsion (GAP) program was established to develop technologies and manufacturing processes for revolutionary, low-cost, environmentally- compliant propulsion systems and to flight-demonstrate these propulsion systems on advanced aircraft. The focus is on the light general aviation aircraft which have six seats or less. "New advanced propulsion systems are the key to tomorrow's affordable, user-friendly general aviation aircraft," said Leo Burkardt, manager of the GAP program at the Lewis Research Center, Cleveland, OH. "According to a NASA Aeronautics Advisory Committee's General Aviation Task Force Report," Burkardt said," replacing today's outdated light aircraft propulsion systems is perhaps the most important factor in helping to revitalize the light aircraft market. This four-year, technology development program will be implemented through Cooperative Agreements with U.S. aviation industry. Two cooperative agreements are expected to be issued in October 1996.

Dwayne Brown Headquarters, Washington, DC December 16, 1996 (Phone: 202/358-1726) Lori Rachul Lewis Research Center, Cleveland, OH (Phone: 216/433-8806) RELEASE: 96-258 NASA SIGNS AGREEMENTS FOR FUTURE GENERAL AVIATION ENGINES NASA Administrator Daniel S. Goldin today confirmed the Agency's commitment to the renaissance of U.S. general aviation with the signing of Notices of Agreement for two new revolutionary engines that will make future light aircraft safer, smoother, quieter and more affordable. The engines are being developed under the Agency's General Aviation Propulsion (GAP) program that is promoting U.S. economic growth by uniting propulsion, airframe manufacturers and other industries with government to develop and demonstrate new general aviation propulsion systems. Goldin introduced the two company-led project teams of Williams International Co. of Walled Lake, MI, and Teledyne Continental Motors (TCM) of Mobile, AL, that were chosen to develop revolutionary technologies for a turbine and intermittent combustion engine, respectively. Modern turbine engine reliability and smoothness contribute to aircraft safety. High acquisition costs have been a major factor hindering their application in the light aircraft market. Designing a simpler engine with fewer parts, automated manufacturing methods and common engine components across a wide spectrum of applications will help to lower costs, making them affordable for the first time to the light aircraft pilot.

At the beginning of the GAP program, NASA promised to transform small aircraft by developing revolutionary new engines and demonstrating them in the year 2000. These radically advanced engines will enable the general aviation industry to produce innovative, affordable engines for the commercial market. Although current general aviation engines are good and have served their purpose well, they require considerable pilot attention, intrude on passenger comfort with noise and vibration, and are costly to buy, operate, and maintain.

NASA's General Aviation Propulsion Program ASAO Involvement in General Aviation Research A lthough current general aviation engines are good and have served their purpose well, they require a considerable amount of pilot attention, intrude on passenger comfort with noise and vibration, are costly to buy, and have high maintenance requirements. Technology is now on the verge of enabling both intermittent combustion engines and turbine engines that will provide the same kind of simple (just push on the throttle for power), nonintrusive (smooth and quiet), highly reliable operation that we have come to expect from our automobile engines. The time is right for developing revolutionary new propulsion systems for general aviation. Thanks to Leo Burkardt of GRC.

General Aviation Propulsion Program T he General Aviation Propulsion program was established to address the technology needs of the general aviation engine industry. The specific goal of GAP is to develop and flight demonstrate revolutionary propulsion systems for general aviation aircraft to support revitalization of the U.S. General Aviation Light Aircraft Industry. This is being done in partnership with the FAA by developing technologies and processes that will result in low-cost, environmentally compliant, revolutionary propulsion systems for light general aviation aircraft. The major milestone of the program is to flight demonstrate fully manufacturable, certifiable propulsion systems in the year 2000 which meet or exceed the cost and operability requirements of the program. S elect one of the thumbnail images below: GAP Turbine Engine Mockup: This is a mockup of the Williams International FJX-2 turbine engine being developed as part of the NASA General Aviation Propulsion Program. It is a high bypass turbofan with a "common core" design which will enable turboprop and turboshaft versions of the engine to be designed and produced. The engine design point has 700 pounds of sea level static thrust with a weight of less than 100 pounds, giving it an excellent thrust to weight ratio. At reasonable production levels, the engine should be cost competitive with current piston engines. When the weight, performance, and installation advantages this engine provides are taken advantage of in an integrated aircraft design, the aircraft fuel burn for a given mission will be comparable to a piston engine-powered airplane with the same payload.

July 27, 2000 GAP Engine Update By Mike Busch OSHnews Day 1 OSHnews Day 2 OSHnews Day 3 ... EAA 2000 Coverage Home L ots of attention is currently being lavished on the new electronic piston engine control systems that are nearing certification: the TCM/Aerosance FADEC, Lycoming/Unison's EpiC, and the adaptive digital ignition system being developed by General Aviation Modifications Inc. (GAMI). While these developments are certainly worthwhile and long overdue, they represent a relatively small incremental improvement to the 40-year-old powerplant designs that are still ubiquitous in today's piston-powered aircraft. But some truly revolutionary changes to aircraft piston engines are in development, and it may be only two or three more yeas before we start seeing these radically different engines powering our aircraft. Not Your Father's Piston Engine TCM's GAP engine is a 200 HP, liquid-cooled, two-stroke, compression ignition (Diesel) engine that runs on jet fuel (or pretty much anything else you care to pour in the tank, including Jack Daniels). Due to its novel design and extremely low parts count, the engine is targeted by NASA to cost about one half as much as today's 200-HP piston aircraft engines. It is quieter, smoother, has vastly better fuel economy, and a 3,000-hour TBO. Furthermore, when the oil companies finally quit making leaded avgas, the GAP engine won't care a bit.

Voyager V-Jet II Williams International Press Release Last fall under a competitive procurement program among jet engine companies, NASA selected Williams International to join NASA in a $100 million cooperative effort to revitalize the once-flourishing light aircraft industry in the United States through small turbofan engine technology. Under the program, Williams and its industry team members, which include Williams suppliers and future aircraft company customers, provide 60 percent of the resources and NASA provides 40 percent for the initial engine demonstration phase. Williams, currently in the component design phase of the engine technology program, is emphasizing low cost manufacturing processes suitable for high quantity production, and is active with key suppliers to minimize material and purchase parts costs. The new Williams engine has been named the "FJX-2." Dr. Sam Williams, Chairman of Williams International, said, "Our objective is to replace aging, piston-powered light aircraft with all new, four-place single and six-place twin, turbofan-powered modern aircraft. This means we must develop a turbofan in the 700 lb thrust category that is very low in cost at a high production rate, is extremely quiet, is light in weight, and is very reliable."

In 1996, NASA initiated the General Aviation Propulsion (GAP) program to encourage and advance the U.S. light-aircraft industry. The GAP program's main goal was to help develop more affordable propulsion systems, mainly engines. Williams International joined with NASA to develop the FJX-2 turbofan engine, the smallest commercial turbofan available at the time. It weighed less than 45.4 kg (100 lbs), with a thrust-to-weight ratio that would allow the development of a new class of lightweight aircraft. This technological breakthrough was a major step forward in the drive to create aircraft small enough to use local airports but sophisticated enough to meet the necessary speed, range, comfort and safety requirements of a commercial aircraft.

39. Air Taxi At Your Service Enlisted through this initiative, known as NASA s General aviation propulsion (GAP)program, Glenn Research Center conducted a small turbofan development http://www.techbriefs.com/spinoff/spinoff2002/t_1.html

Air Taxi at Your Service The EJ22 engine, which has a low noise level, light weight, and low fuel consumption, delivers over 770 pounds of thrust while only weighing approximately 85 pounds. In the past, only the rich and famous may have had access to personal jets designed to whisk travelers from city to city without the inconvenience of crowded major airports. Now, however, with NASA's support and the work of several companies determined to redefine personal air transport, flying direct to nearly any city from the closest local airport may soon become a viable option for everyone. In 1996, NASA initiated a program designed to revitalize the U.S. light aircraft industry through the development and commercialization of more affordable propulsion systems, including turbofan engines. Enlisted through this initiative, known as NASA's General Aviation Propulsion (GAP) program, Glenn Research Center conducted a small turbofan development competition among major U.S. engine builders. As a result, Williams International of Walled Lake, Michigan, won a cooperative research and development program with NASA, and work on the new NASA/Williams GAP engine began. A year later, Vern Raburn, a successful entrepreneur in high technology, sought to apply digital technology; efficient lightweight engines, such as those being designed through the GAP program; high volume manufacturing; and high technology business practices to a whole new type of general aviation company. Raburn met with Dr. Sam Williams, president and founder of Williams International, and created Eclipse Aviation Corporation of Albuquerque, New Mexico, to provide alternatives in air transportation.

Hartzell Propeller Achieves Certification of Propellers for Walter M601 Turboprop Engines Cascade Flying Service First to Certify New Hartzell / Walter Propulsion System Hartzell Propeller Inc. has received certification from the Federal Aviation Administration (FAA) for a new propeller model designed specifically for installation on Walter M601 series turboprop engines. PIQUA, Ohio - September 10, 2001 Hartzell Propeller Inc. announced today that it has received type certification from the Federal Aviation Administration (FAA) for a new propeller model designed specifically for installation on Walter M601 series turboprop engines. Additionally, Cascade Flying Service of Garfield, Washington, has obtained a Supplemental Type Certificate (STC) for installation of this new Hartzell propeller and a Walter M601E-11 engine for Air Tractor AT-300 / 400 series aircraft. Another installation of the Hartzell / Walter propulsion package is currently in development. Lancair of Redmond, Oregon, plans to offer this package as an option for its Lancair IVP kit. Customer demand for improved performance propellers initiated Hartzell's relationship with Walter a. s. of Prague, Czech Republic. In April 1999, the two companies embarked on a project to jointly develop and certify adaptations of Hartzell propellers and Walter turbine engines.
