Love the engine and its design, but if price is about 100K is incredible out of price from what was stated as a goal price by deltahawk... which whas about half that price.

Both a turbo and supercharger spin like...a turbine. Low vibration, no reciprocation. Typically quite durable. And partially redundant. What DH is missing is the valvetrain/cam, ignition system. Low parts count. Not a ton to go wrong. Seems like a good tradeoff.

I'm anxious for actual info to released. Why a V4? Why inverted? It's a 2 stroke diesel with a turbo..... but why does there also appear to be a rotary lobe blower underneath? How is this engine going to be better than the traditional horizontally opposed 4 strokes? There are way less parts with a 2 stroke and no need for ignition with diesel.... but they burn dirty and loud. Come on, spill some actual info for us.

First of all - it will run exclusively on Jet-A for most applications. Why inverted? It is direct drive and inverted gives you clearance for the prop in planes designed for flat/boxer engines.

I would like to know how the oiling system works. How the Scavenging works. If the engine is inverted with the cylinders down wouldn't oil collect in the cylinders if not used for a while? Like a radial engine? Would you have drain the cylinders before starting? I would rather mount it up right.

@@jupabalo98 the current lineup covers 360, 390, and some 470/540 applications with 180, 200, and 235 hp models available. They have a 300-350hp 6-cylinder version in development of the same block design they hope to unveil at the 2025 airshows per the staff at the show. If you look at the poll at their website the number 1 engine requested is for a 300hp Piper PA32 replacement. Continental just announced their Diesel / Jet A CD300 is now available for Cessna 206 retrofit packages but it is a much more complicated engine.

My friends were so sick of me talking about this engine for the last 15 years. I thought the Delta Hawk team were on the right track. Direct drive, mechanical fuel system, turbo charged, supercharged, no valve train, no ignition system, clean looking installation low frontal area, (liquid cooled) so no shock cooling, and most importantly no fadec. I have always subscribed to the philosophy that once an engine is running as long as it has fuel and air and the throttle is held open it should continue to run! Ne electrical power required. This is a game changer for aviation. As a Canadian aviator I look forward to a cabin heater core, rather than a heat muff, safer with more heat available. I'm hoping there is an immersion type block heater, engine preheat for winter operations. Congratulations Delta Hawk !!!!!

to those of you worried about the weight- the DHK180 delivers 363 Ft. Lbs. of torque @ 2600 rpm's. the io360 produces an ESTIMATED 389 ft. Lbs. - I say estimated because both lycoming & continental flat REFUSES to publish those numbers. guessing them from a formula will NOT yield accurate results in real world performance. HOW do I know this? simple experience and common sense. you cannot compare the performance of an engine with a 26 to 1 compression ratio and a squared stroke to bore- with an engine that has a 7 to 1 compression ratio, A 4.25 bore & a 3.5" stroke. they are two different animals with 2 completely different performance curves. ANYONE who's ever ridden in a chevy 1 ton with a 454 v8 will tell you that it's a great engine- if you want to go cruising. but hook 13k Lbs. of trailer behind it? a dodge cummins with less rated HP & way less engine cubes will walk all over it. plug THAT into your stupid equation. the difference? DIESEL. high compression, high RATED torque. gas engines perform well where high hp, rapid acceleration and a broad power band (again- hp) are good- like racing. what do big rigs use? DIESELS. why? because diesels LOVE to be strained- LOADED- and then operate at a set speed, ALL DAY LONG- aka- 80k lbs at 55mph.. ALL DAY LONG. INTERNESTING. what do planes need? 2600 rpm's... without slowing down, even under high load... ALL DAY LONG. the DHK180 was bred, born and BUILT for that. DIESEL. the lycontisaurus lawn mower engines? DISMALLY INADEQUATE for it. air cooled? FAIL. low compression? FAIL. horrible efficiency? FAIL. I am REALLY going enjoy watching this engine rise to the top. KUDOS to dennis & wife for their wonderful work in bringing GA into the 21st century.

KUDOS. for not taking what I am ABSOLUTELY POSITIVE would've been a HUGE bribe (the ignorant would say 'buy out offer') and also plenty of threats... and still stood his ground. you & elon musk now have something in common- you both kicked the big oil monster in the teeth & lived to tell about it. we thank you sir- for you efforts & your contribution- and we look forward to your future engines.
