status of Delta Hawk diesel
The Delta Hawk has been VERY slow to come to the market, yet I have a
vague memory of the first samples being very close to release. Anyone know the details, or of any flying apart from factory test/demo planes? TIA, |

This motor program is as close to vaporware as on can get. Just my opinion........ |

He has NEVER had one of his engines flown in the 30 years that I have been aware of it. If it sounds too good to be true, it probably is! (Like Zoche's engine) |

I don't know about the vaporware aspect but I did notice where they upped the price to the point that it would make no sense to even consider one over any other engine. Their initial concept and price level looked attractive but the last time I looked, I laughed and never went back. |

Lots of hype on Diesels in airplanes, little action.
I wonder if the problem is the sharpness of the combustion event destroying props?

" wrote in message ... Lots of hype on Diesels in airplanes, little action. I wonder if the problem is the sharpness of the combustion event destroying props? Not at all. The problem is that diesels are usually heavy as crap to withstand the higher combustion chamber pressures that diesel engines have, mainly. 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. Of course, the largest problem is having the money it takes to develop an engine and get it to market. Costs can be enormous. -- Jim in NC |

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. |
