Please explain how this is the most exciting development. It was a 20 second run on a test bed showing zero information on thrust, wattage, or anything of use. Not to mention that turbofan engines need to be operated on stands that are stabilized in concrete or suspended from massive assemblies while this is on a cart with wheels that aren’t even chocked.
Hmmm a quiet electric motor..... not particularly impressive. Run of the mill actually. The quiet MT propeller is pretty good. To be impressive; you'd need to run this motor at cruise power for an hour, divulge what that cruise power is, and show the whole battery pack and weight in the same footage. Batteries don't make electricity, they store it, so the emissions are produced somewhere else. Structurally, aerodynamically, environmentally, and efficiency-wise, electric airplanes make no sense until battery energy density has increase 10 fold over what it is today to equal ICS airplanes.
@@terke1230 We will see about that. While batteries are by no means perfect, we may have just arrived at the point where they're _good enough_ and that's when electric planes will take off. They became good enough for electric cars a couple of years ago, and see how that has exploded (in a good way). And about "the emissions are produced somewhere else".... Yes, we *know*, dude. But, you're leaving a lot out electric motors are much more efficient, quieter, have no local exhausts and in a sense are fuel-agnostic; the batteries can be charged with electricity from wind turbines, coal plants, solar panels, gas plants, etc. And the exhaust from large power plants is much better controlled than that of individual airplane engines (at least in developing countries), and large power combined cycle power plants are much more efficient. And with each solar plant, wind plant etc becoming operational, the entire electric airplane fleet will become cleaner. The advantages are real. What I'm curious about is the economics of it all. Batteries are expensive, and have a certain life span. That will amount to €/$ X per flight hour, and we'll have to see how that works out in the long run. Also, charging will take longer than refuelling, there's currently no way around that, and it remains to be seen how that will effect economics. In the early years, subsidies may have to be employed, as they were for electric cars. We'll see. In short, I don't think there's a problem with the technology. The challenge may be economics - and I'm optimistic about that.
@@SolarWebsite The batterys are still not good enough, and now they are giving up on that idea and are building "hybrid" planes, IE a jet engine/generator inside the fuselage, driving the electric motors on the wings. Spreading the exhaust where they fly, generating the electricity from jet fuel....
Imagine if that could fit in something truly iconic like a spitfire (or replica of a spitfire) I imagine it would sell like hotcakes if people could buy an electric spitfire
As much as I am 100% behind your concept, layout, approach and goals - it would be nice to publish "rough numbers" concerning rated power and dB at the same time. Please keep in mind that you have to influence legislation in many foreign markets AND the public concerning the noise profile. 400 km at 215 ktas with 750 m take-off distance will put you hopefully in many small markets where the prospect of much for silent 19 seaters without security hassles will receive a warm, prosperous and more silent welcome by the flying public.
I have one thing that I just somehow need to know how do you guys eventually know if constant thrust can be executed into a prototype electric aircraft that could be in production in 2030?. Will you guys have all the time to find flaws while testing and sell it nationally right in 2030 like, Thermodynamics, Gross Weight Payloads (including MTOW), Aerodynamic Stability, Amperage, Constant Thrust, Reliability and Cost. This, was a long time prediction since I was a kid in love with airplanes and how they work, very expensive and and beautiful machines but, this really had me wondering if other electronic powered units are being put into ideas by other companies including aeroplanes. If anyone sees this comment the Heart Aerospace teams and engineers should take the time and patience for a new aircraft and a new propulsion system to adhere to the FAA's safety regulations if it's updated in 2030. I'm just mindblown that my prediction came true in the world of aviation, keep up the good work. 👍👍👍
I got a flat tire when landing my Cherokee 235b once. One of the main tires. I kept it straight down the middle until it stopped. Crazy thing, I couldn't get the plane to move again off the runway after stopping. That plane has a 0-540. I thought this is crazy, why cant I move? The FBO had to bring a spare wheel tire out, put it on and it was back to normal. So from a dead stop, its not too hard to hold them down. Regarding the tire, I was loosing air, the A&P put an old tube on. Don't reuse old tubes in aircraft.
I didn't think I would tear up... That was beautiful.
This is probably the most exciting development in the electric aviation industry. I've got to wonder if this was a full send or just a partial send.

Awesome. Simply awesome! You guys keep up the excellent work! The sound is gorgeous, showcasing that it’s powerful yet still remarkably quiet.

Interesting stuff. We'd like to see more if possible! Was this engine run up to full power?
I think so

keep it up! :)
I wana have one for summer
Dear heart aerospace,aerlingus Reginal is starting up ,maybe you could send them some information on your great airliner .love from England.✈️🕊️
Does it have variable pitch propeller blades? Then it could have regenerative retardation on descent
It would be called regenerative windmilling.
Need some air conditioning in my bedroom. Will this do?
How much thrust?
Sir my personal use how to buy electric motor use aircraft
I have one thing that I just somehow need to know how do you guys eventually know if constant thrust can be
executed into a prototype electric aircraft that could be in production in 2030?.

So disappointed 😮 We didn’t see the lift off 🙄🤭
omg
Why the platform is not moving?
Brakes on wheels perhaps? (omg)
It's designed to test the engine, not test whether it can push a wagon. This thing is going on an airplane not a fisher price toy car 🤣
@@slendii366 Yes.... That cart should fly away! This is more just a fisher toy!
@@TheCadman67 re evaluate my comment and come up with a response that lines up better with the intentions of this company

cool , now put it inside a ww2 fighter plane
