Turbines - will Innodyn succeed?
Saw a story on Innodyn turbines. Are their claims realistic? Will they
succeed? 188 pounds? 7 gallons per 100 hp? Can they scale this ...DOWN? Would a (80-100 hp) turbine weighing 100-140 pounds be a hit? Burning 5-6-7-8 gallons per hour? Again, can their 165 hp - 255 hp turbines be scaled DOWN to a Rotax 582/912 size? http://www.innodyn.com/aviation/faq.html (From Products page) Innodyn offers a number of Turbines to meet the experimental pilot's needs. While every model is based on Innodyn's core Turbine design, each is optimized to provide the strongest performance. Each Turbine weighs no more than 188 pounds, and is designed for use with our firewall forward kits. We're confident that our Turbines and firewall forward kits are right for the vast majority of experimental applications. Please feel free to contact us with any questions. Our Turbines are designed for output speeds of 2,000; 2,250; 2,500; 2,750; 3,000; and 3,600 RPM. We recommend the use of 2,750 RPM for fixed-wing aircraft applications. Innodyn 165TE 165 Horsepower Introductory Price: $26,500 Innodyn 185TE 185 Horsepower Introductory Price: $28,000 Innodyn 205TE 205 Horsepower Introductory Price: $29,500 Innodyn 255TE 255 Horsepower Introductory Price: $34,500 Montblack |

Innodyn took the initiative in inventing 188 pound turbines. |

Innodyn took the initiative in inventing 188 pound turbines. The Boeing Model 502 - in the 1950's - weighed 140 lbs. and put out 200 hp. Oh, wait - you said 188 pounds. I stand corrected. Why would they want such a heavy engine? Gawsh, technology has sure come a long way in fifty years. Rich S. P.S. The Boeing Model 500 Turbo-jet weighed 85 pounds, developed 150 pounds of thrust, and was 29" long, 22" in diameter. The extra 55 pounds of the 502 was the gear reduction. |

Why aren't more old Boeing engines finding their way into homebuilts? A 140 bound 200HP engine sounds sweet. With a couple of those I could get serious about my dreams to build an ME262... ;o) Tony |
