In conventional aircraft design the principle reason for the separation of propulsion and lift is the design simplicity: Modularisation of thrust components allows them to be positioned in such a way as to avoid unwanted interactions with wings. This has the added benefit of allowing competition between propulsion providers without undue compromise to the airframe development. One of the key challenges with eVToL (or indeed elec aircraft in general) is that the whole technology only reaches minimum value when the unique characteristics of electric propulsion are fully exploited... i.e. Elec aircraft only make sense (below the 400W/kg battery threshold) when distributed propulsion is used... the X-57 is a prime example of this.

I wonder about the possibility of increased propeller efficiency on these smaller electric motors using a single-sided propeller? One of the two asymmetrical load (balance) could easily be addressed with a weight. In full sized aircraft the asymmetrical thrust load would tair apart most structures. But it may not be too much for these types of smaller electric motors. The higher RPM's would also make it easier to dampen out the vibration. Efficiency drops as the number of "tips" (blades) increase. Meaning a 4-blade propeller has higher losses than a 2-blade of the same disc diameter.
@ErikssonTord_2

I think there is one speed record still standing with a single-blade aircraft, and that was set ages ago! Not so sure high rpm is easier to dampen than low rpms. Ages ago (soon 100 years ago) you could buy fixed-pitch single-blade props for small low-power aircraft, and the only practical gain was better glide ratios, power off. And you'd get more vibration, as one side had a propeller blade that flexed under load, while the other just had a heavy lump of metal. Today's multi-blade props for private aircraft increases climb a lot, while some do not do much better in cruise, efficiencywise. Three-bladed propellers have less vibration issues then two-blade, and five-blade is even better than three-bladed! To keep efficiency up the propeller tips should travel at Mach .6-0.8, and lots of power combined with two-bladed props has never worked. The late Spitfires had five-bladed propellers, while the very first had two blades!
@CandC68 Жыл бұрын
I would suggest designing the propeller blades to "park" so the blades add to lift when power is lost. Maybe a two blade system with pitch defaulting to horizontal and lift setting. Instead of random feathering just causing drag.

Looks like an intriguing design. For quite a time, I wondered if ducted fans might push performance, even for bigger props. Coleopters/"circular wings" habe been tried every now and then, but never caught up. Many creative guys tried a range of ideas and details with RC models, but, whatever gets to work at 1:5 scale or even smaller, not necessarily is feasible at full scale, be it too heavy/lacking payload, too expensive, complex or fragile to build at 1:1? The design of current commercial aircraft might be dated, but seems to have proven itself as a compromise between performance, cost and durability?
@ErikssonTord_2
2 жыл бұрын
Big ducted propellers weigh a lot, thus even less suitable for an electric aircraft. Secondly, all duct designs work best at one speed, one lift situation, while propellers are fairly easily made in-flight adjustable (old technology, since the birth of helicopters). So ducts have a restricted speed range where they are effective, and in an electric aircraft efficiency is the paramount concern, till the day we get much better batteries! And just all the added wetted area is a huge problem at speed.

There are different configurations, but in general you have one wing in the middle that extends left and right like regular wings in a normal airplane, but instead of connecting to the hull it has a circular section that goes under the hull. So it goes straight, then makes a "U" some distance away from the hull and then it goes straight again. There is also one configuration where this "U" just sits behind the cockpit. Then at the end of the plane is a ducted propeller that can either tilt downwards or straight in line with the direction of flight. In the downwards position the "U" section of the wing acts a an extension of the duct, so air flows overt the "U" into the duct and into the propeller. And in the strait position the "U" does not connect to the duct. Even using my eyes this was hard wrapping my head around it...
@jefferee2002

I believe what he is saying is that there is one school of thought to keep the part of an aircraft that creates lift, like wings, separate from the part that provides propulsion and forward velocity. This way, if the propulsion side fails, the airplane can still act as a glider of sorts with the possibility of landing safely. There is another design concept that integrates propulsion systems with physical lift mechanisms such as wings more directly which can lead to increased efficiency. However, if the propulsion system fails, the lift producing structures will not be enough to keep the aircraft aloft. Independent electric motors could help offset this danger, since it would take several motor failures to present a danger to the aircraft, which is unlikely.

The angulation of the single thrusting element to bring both the lift and propulsion into place is not a safe method of flight.

The late Spitfires had five-bladed propellers, while the very first had two blades!
I would suggest designing the propeller blades to "park" so the blades add to lift when power is lost. Maybe a two blade system with pitch defaulting to horizontal and lift setting. Instead of random feathering just causing drag.

Which I have found isn't a bad thing. It may not occur to trained folks to think outside their box. Who knows if silly concepts might trigger a new thought.

Looks like an intriguing design. For quite a time, I wondered if ducted fans might push performance, even for bigger props. Coleopters/"circular wings" habe been tried every now and then, but never caught up. Many creative guys tried a range of ideas and details with RC models, but, whatever gets to work at 1:5 scale or even smaller, not necessarily is feasible at full scale, be it too heavy/lacking payload, too expensive, complex or fragile to build at 1:1? The design of current commercial aircraft might be dated, but seems to have proven itself as a compromise between performance, cost and durability?

Big ducted propellers weigh a lot, thus even less suitable for an electric aircraft. Secondly, all duct designs work best at one speed, one lift situation, while propellers are fairly easily made in-flight adjustable (old technology, since the birth of helicopters). So ducts have a restricted speed range where they are effective, and in an electric aircraft efficiency is the paramount concern, till the day we get much better batteries! And just all the added wetted area is a huge problem at speed.

@@ErikssonTord_2 To my understanding, a wide speed range is a must-have for freight machines and WW2 fighters, but not for a plane that will do cruising speed for >90% of their time of operation. Weight on the other hand is a factor, and even more: rotating mass leading to gyroscopic effects.

There are different configurations, but in general you have one wing in the middle that extends left and right like regular wings in a normal airplane, but instead of connecting to the hull it has a circular section that goes under the hull. So it goes straight, then makes a "U" some distance away from the hull and then it goes straight again. There is also one configuration where this "U" just sits behind the cockpit. Then at the end of the plane is a ducted propeller that can either tilt downwards or straight in line with the direction of flight. In the downwards position the "U" section of the wing acts a an extension of the duct, so air flows overt the "U" into the duct and into the propeller. And in the strait position the "U" does not connect to the duct. Even using my eyes this was hard wrapping my head around it...

I believe what he is saying is that there is one school of thought to keep the part of an aircraft that creates lift, like wings, separate from the part that provides propulsion and forward velocity. This way, if the propulsion side fails, the airplane can still act as a glider of sorts with the possibility of landing safely. There is another design concept that integrates propulsion systems with physical lift mechanisms such as wings more directly which can lead to increased efficiency. However, if the propulsion system fails, the lift producing structures will not be enough to keep the aircraft aloft. Independent electric motors could help offset this danger, since it would take several motor failures to present a danger to the aircraft, which is unlikely.

The angulation of the single thrusting element to bring both the lift and propulsion into place is not a safe method of flight. There must be an auxiliary element to fall back into in case of sudden failure of any type. We can not scarify safety on expense of efficiency. This is great for moving things, not for moving human.

the landing gear would have to be extremely long. and therefore vinerable to breaking on contact to the ground. when landing.
Not enough emphasis was placed on the fact that these big pusher ducts will have to contain 'coaxial' propellors, as the toque effect of a single prop would be uncontrollable, or would absorb a significant amount of thrust to correct. I think I'll stick to wings...

Am I wrong? Doesn’t this design forward motion to achieve steering? Also, if this design tried to hover like a helicopter, having only two rotors, it would not be able to maintain balance left to right. I’m not saying this is a bad design. I’m just saying people should not expect it to do vertical takeoff and landing like a helicopter.
3:06 Why would the electric motors spin up before starting the engine? That makes no sense with regard to battery load. Those small motors are electric, are they not? Oh - I am guessing that the main engine is electric as well. I was thinking it was internal combustion…
