@davidwoodward6112 Engine manufacturers who have delivered reliable products for nearly a century. Look at Rotax. For all of the high technology and new design it still doesn’t have any better power to weight than a Continental O-200 that’s based on a nearly 90 year old design! And the Rotax has four failure modes the Continental doesn’t (dog clutch, gear box, coolant leak, additional throttle linkage).

[@PhilipFly11]

@@calvinnickel9995 The Rotax 916iS now produces 160 HP, 141 HP continuously, right up to 18,000 feet. The Rotax 912 series engines do have more clockwork to break, however, the gearbox is very reliable, there are no magnetos to maintain or fail and the fuel injected Rotax engines have no carburettor to maintain or to ice up. Carburettor icing of the O-200 has caused thousands of engine failures and hundreds of fatalities. Carburettors should never be installed on an aircraft engine. The DeltaHawk engine is much better than both. No crankcase halves to fret. No separate cylinders to fail. No camshaft, lifters, valves or guides to fail. No ignition to fail. No carburettors to ice up. It is a great shame that the DeltaHawk was not certified 25 or 30 years ago and offered at a price competitive with the Lycoming IO360 and IO390 that it replaces with V8 versions to replace the Continental IO520 and IO550 and Lycoming IO540 engines. Continental have, of course, moved over to diesel with the CD300, however, that is a standard Mercedes automobile engine with reduction drive and accessories added by Continental. It looks like the Continental CD300 is much quieter, smoother, more efficient and more reliable than the IO520 but there are very few new certified piston engine aircraft being manufactured today and developing an STC for legacy aircraft takes a lot of time and money. Cirrus favours Continental and Lycoming air cooled gasoline engines and Diamond install water cooled Continental diesel engines.

This is exactly right. "Airplanes are not allowed to crash, and childrens' toys must be safe". Tort reform in 1986 got Cessna to restart its general aviation business, but its still far too expensive. A decent panel with modern avionics can cost 100s of thousands of dollars. Engines and maintenance are expensive, tedious, and slow to adopt new better tech. Thats not because the tech in general aviation is necessarily otherworldly, it's because of the risk portfolio (lawsuits) any certified aviation supply chain has to mitigate.

The long and short is that it's a piston engine that can run on kerosene-based jet fuel instead of general aviation fuel, which is basically a grade of leaded gasoline. That makes it cheaper and cleaner to operate, and allows more kinds of small aircraft to use a widely-available industry standard grade of fuel.

I didn't learn anything from the video so I went to their website. It is a 4 cylinder diesel, turbocharged, non geared with glow plugs, 180 to 235 HP. I'm not sure why it took so long to develop, (possibly certification). The fact that it uses jet fuel is a big plus since Avgas is more expensive and more difficult to find in many countries.

Diesel fuel is cheaper and much less volatile than av gas. With this diesel 2 stroke, having much less moving parts than a gas engine is always better. I remember back 15 or 20 years ago when these diesel engines were being billed as being much lighter than their gas counterpart engines. Comparing the weight of this diesel to that to the other 180 hp gas engines out there like the O-360s, the 335 lb weight is considerable. With the 235 hp versions compared to the 470 and 540 engines, the weight is mush better. But to me, the $110k starting price for the 180 hp versions is a bit steep. That's nearly twice the price of a factory new IO-360 and $35k-$49k more than a factory new IO-470/540.

They will never beat the incumbent at a higher price point when existing offerings have millions of proof hours on them and cost less. I hope Delta Hawk has enough cash in reserves to sell these at a price that is compelling enough for owners/builders to take a risk flying behind a new product, and take an even bigger risk that Delta Hawk survives and is around long enough to provide service and parts 10 years from now.
