TIA, If you want an engine that runs on diesel, you HAVE to take a look at this video: http://www.youtube.com/watch?v=Yle0bNfmf0E It's a turbine engine mounted on a CH-701. Kinda neat! I suppose if ~90 HP isn't enough, you could always consider a twin design. ;-) It said that 90 HP was turning a 68" prop! -- Richard Lamb email me: web site: www.home.earthlink.net/~cavelamb |

wrote: In article , says... Aero-diesels impose from the start a kind of supercharger, adding complexity, weight and more things to go wrong. Hmm, well a 2-stroke like the delta-hawk does. On the other hand on the Deltahawk there are no - magnetos, spark plugs, leads valves, camshafts, followers, pushrods, rockers cylinder head gaskets (head integral with cylinder) Engine has *no* need for an electrical supply to run. I have followed the development for a while and very much like the concepts behind the deltahawk. Some makes add also a PSRU, once again adding weight, extra maintenance and cost. Engine speed is such that no PSRU is required. The other problem is that fuel pumps and injector systems used on diesel engines usually will not work using jet fuel, which is the fuel these engines are normally going to be using. Deltahawk designed from outset for Jet fuel. Of course, the largest problem is having the money it takes to develop an engine and get it to market. *Costs can be enormous. DH are still there. They claim that "Experimental" engines are available now with certification Real Soon As I said, I like the options they have chosen for their clean sheet design. There seems every prospect that they will be safe, robust and economical if the fuel tax in any particular jurisdiction does not rule that out. |

It said that 90 HP was turning a 68" prop! Youtube text description says 12gph fuel use!!! A 3 bladed 68 inch prop, burning that much fuel even at turbine inefficiency sounds like a buttload more than 90 HP, to me! -- Jim in NC |

BTW, there is quite a bit of information about this setup on the web. Velly intelesting... -- Richard Lamb email me: web site: www.home.earthlink.net/~cavelamb |

TIA, I have been watching them over here avgas europe 2.5 euros a litre Jet A1 1 euro wish continentals ran on diesel with magneto's forget the efficiency of diesel its just cheaper by a country mile,dont worry by the time Deltahawk come out with a for sale product I will have developed a nuclear fusion reactor turbine drive that runs on water and weighs 50 kilos |
