How do you do the circuit breaker upgrade? LED?

This was actually really interesting, I learned a lot

Now if you make it with a pressurized cabin, it will be perfect. Turbine engines do best up high, using oxygen masks and nasal cannulas so you can fly them where they like it, sucks.

POR FAVOR , PONGAN LA TRADUCCION EN PANTALLA AL IDIOMA ESPAÑOL, Y PODERLA LEER EN ESPAÑOL. YA QUE ES UNA TRADUCCION TECNICA, Y LOS QUE NO DOMINAMOS TECNICAMENTE EL INGLES EN LA ESPECIALIDAD DE LA AVIACION, PUES NOS ES IMPOSIBLE ENTENDER EXACTMENTE. MOS DETALLES, SINO LA TRADUCEN AL ESPAÑOL. MUCHAS GRACIAS. THANKS VERY MUCH. SINCERILY YOURS. CAMILO PEREZ PEREIRO RESIDO EN FLORIDA STATE.

0:54 Indeed ..I was reading so many safety mags I was starting to lose my confidence mojo I started looking for an potential accident under every rock in the garden...so to speak. This became distractive to the task of actually flying the plane.

You sound under water. Fix the sound

Should come with no seats! Cargo only!

Light wing loading is why I have no interest in these

Interesting,vi have been looking for exhaust emissions for this engine (CO CO2 NOx unburned fuel), data per RPM per fuel type. If anyone can point me to a link where I could find this data, please let me know. Thanks in advance.

Is this engine friendly if mounted two both on wings?

A friend of mine developed a prototype of a 2-stroke aero-engine based on the Detroit Diesel. It worked perfectly and was deliberstely targeted on the same weight/output as standard-fit Lycoming/Continental.360s. No electronics and standard components and no torsional problems. Analysed as a difficult market and was dropped fir financial reasons. Still have the drawings....

The Russians used 2 stroke diesels on their WW2 bombers.

Great for attack drones with A.I.

Put it on carbon fibre aerocet floats please and I will take it.

I know this is certified aviation and all, but that's rather overpriced. It's a lithium battery, in a box. Nothing special that I can see even if it's the highest quality stuff they can get from China.

Would this engine fit on a 1956 Cessna 172 ❓ Would one need a redrive on it ❓

What's the TBO for this 110,000 experimental engine?

The 100-120 hp, at a reasonable price is wide open right now.

I have a small two seater TECNAM which i converted with a MAZDA 13B ROTARY car engine in my garage ---- bypassing these ASTRONOMICAL prices of aircraft engines --- and its performing better than any of those high end manufacturers engines ---- much better

I’m drooling. Great video and explanation. Beautiful aircraft

Estimated TBO schedules and cost?

How much power does it have?

I owned N838Q for the last 2 years. It was a wonderful aircraft. I put 400 hours on it. Took it to the Bahamas, took kids up in Young Eagle flights, visited family, etc. I could do a 600 mile cross country at 120 knots ( I added an e-prop) with a 16 gallon fuel burn of car gas. It was destroyed in my hanger under 8 feet of water by hurricane Helene. Whole airport in Hendersonville NC was wiped out.

My Rotax will have me in the air in just a few short hours, inexpensive, dependable and easily overhauled or replaced.

What you did not say, why both turbo and super charge, why not just one or the other. Is the supercharger positive displacement, and what are the weight compare with a standard IO-360?

I want to see the engine running - how much noise?

No real data. We need pricing and weight data.

I thought it hasn’t been mentioned but it is also supercharged to save weight along with the turbo

There are a few other issues 2-stroke diesels have: reduced fuel efficiency, reduced longevity and reliability and much higher emissions, without the aid of industry standard ECMs. Even if DeltaHawk flies under the emissions radar for a while, the issue will eventually put an end to this engine. A flight school overhauling two Lycoming 0-180 engines in a Piper Seminole will spend $50k to $70k. Retrofitting two DTK 180s will cost upwards of $250k, with labor. That's almost double what a legacy Seminole is worth. This engine will likely become a boutique product for a handful of buyers. I'd be surprised if it sells more than a dozen units a year.

At $110k, (probably closer to $150k for the 235 my aircraft would need), this engine is a non-starter. The message owners and pilots are sending to engine makers is: Durable, techy, reliable, but most of all, AFFORDABLE. Are we being heard? Not yet, apparently.

The venerable two cycle diesel engine has been around for years. Delta Hawk has a new twist using the 120 degree v4 configuration is inserting. Getting a 2stroker clean enough to pass emission is no small feat. EMD got their big engines cleaner using a d deck ecm, at least they no longer smoke.

Thank you! Finally, someone explained the configuration.....nice!

This is a direct off-shoot of the turbo encabulator

And as a bonus, because it's installed upside-down it's good for inverted flight!

These companies still don't understand how this works. They need to sell the first 500-1,000 engines at a deeeep discount over an equivalent Lycoming or Continental to owners who are willing to help them prove out the design. 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. The equivalent IO-360 costs between $40-50k. Once they get past market acceptance and clear proof these things are reliable and serviceable, only then can they maybe ask for the same price point as similar 180hp engines. They can accept this reality or die like the majority of aviation engine start-ups. It's a cool engine and novel approach but numbers don't lie.

I tested this as well and live in a "military" intensive area of the country with many Outlying airfields. The Emergency glide will take you to both Military fields as well as Private airstrips...it is a great tool to allow the pilot to trouble shoot and not have to initially worry about flying the plane.

i had the latest garmin glass panel installed in my 85 p 210 , love it pacific avionics installed it 4 months ago.no issues. does what i paid it to do what is flight safety? lol i refuse to have a 20 something kid try to tell me how to fly my plane which i have owned since 1987 i do see a lot of people get to technical on radios. i am flyng my p210 to europe in a few weeks made the trip a few times over the years in it. now should be a bit nicer with the new radios and why do people take it so serious? i donot think people have fun anymore. take themselves way to serious, i have over 17000 hrs from crop dusting to helicopters now i go where i want when i want. no more non pressurized aircraft my backup plane is my 1980 p337

The name "sport" tell you why they are crashed! Carelessness, complacency, arrogance, risk taking, showing off.....

Is there any chance for a Glassair Sportsman 2+2 soon?

So no plans for the Pipestrel Panthera? That sled would go 260 knots at 19,000 with your 235hp version.

I wish they were able to keep the prices at that point.

I like to see a proven product! Wheres the beef?

Oof, every show I see these guys at, I shake my head and observe a moment of silence for their investors.

Great insight! Thank you!!

So it uses a sleeve valve setup for intake and exhaust valves ....similar to the old British, Bristol radial engines?

Delta Hawk is a blessing for Aviation . Also very excited about the 6 cylinder engines being developed.

Another one to bite the dust! LOL

The aviation insurance industry has been the tail wagging the dog since 2008. They will consider this an experimental engine until there are a couple hundred thousand trouble-free and claims-free hours. Insurance rates will be horrendous if available at all.

Why is it upside down?

So 40% lower fuel consumption than an IO-360 running LOP?- That's .24 BSFC- better than the best large 4 stroke diesels. I call BS on that. 2 stroke small diesels have similar BSFCs as a Lycoming running LOP- even by their own numbers. 235 hp from 200 cubic inches- I predict they will be way de-rated for MCP, otherwise it won't last very long. Typically rings, ring lands take a beating here unless they have steel lands.
