This could be an awesome student competition or class assignment to get kids into STEM
Awesome! I have a design I’ve been tinkering with since Covid started. I believe in it and I know it can be built. Looking forward to sharing it with you. I’m not worried about idea theft, I’d be honored if somebody is able to actually manufacture it. The purpose (in my opinion) is to make vertical flight popular and safe.
I fly helicopters and jets professionally and have concluded that traditional helicopters will never become mainstream because they’re too complex and expensive. My design solves this problem.
Thanks again for the great channel!
I plan to publish the ideas in a video so its associated with the person who made it
@@ElectricAviation you should also help them get the patent on there idea.
@@RobThomeBogeymanFPV The idea of a basement inventor patenting an idea and getting rich are not realistic, the patent system mainly exists for "mega corportations" to continue their monopoly. I've worked in a lot of industries and I'm telling you first hand, the patent system doesn't exist in it's current form to protect the "basement inventor". The challenge only allows for the use of specific motors and propellers. Rob, the scope of your worries is way out of calibration my friend. I'm excited about this because I like to draw personal flying vehicles and like the author said, it's to get your creative juices flowing.
That is true. The company I work for primarily makes diesel engines and is the largest in the world. We have a dedicated team of lawyers, Engineers and Scientists just for patenting. When I went through the procedure, I realized its nearly impossible for a patent to be submitted by an individual. The cost involved and even the expertise required just to draft a patent is very steep. If one reads the language of patents you will realize, Plus its a back and forth process which can take a very long time.
Rob Thorne, Simple question that will confirm things. Can your aircraft idea autorotate under 500feet?
Do you want us to do all the work including the design. Based on your parameters. That should easily cost you at least 50 to $60,000. No thank you not giving up ideas like that for you. Or anyone not cute. You guys are crazy
Its not about money. We just enjoy designing aircraft
Hell yeah! This is going to be fun! Keep doing what you do, this is the best electric aviation channel on UA-cam! I'm entering the competition for sure.
Awesome, thank you!
This is great! Looking forward to seeing what people come up with. Maybe I'll join...
Surely this idea has been considered and dismissed. An electric vtol powered buy an APU auxiliary power unit fueled by jet fuel. The APU produces electricity supported by a 5 minute battery reserve. Honeywell has come out with such an APU but I can’t get any specs such as weight, fuel, consumption, and power output. In theory, this would increase range and flight time.
Any comments? The proposal is a hybrid-powered eVTOL. Surely someone has a comment of the feasibility and practicality of using Jet fuel to run a turbine (APU) to produce electricity to power the eVTOL with 5-10 Li-Ion battery backup
This is awesome! Thank you for putting forth this great challenge. 👍
You are so welcome!
So you want someone to do your R&D for $300? If someone possesses the skills to do as this channel asks, do yourself a favour and don't give away your invention that could make someone rich for $300.
You are just giving these people thousands of design ideas.
By the way I have been working on an idea for a very much more reliable, safe and four times more efficient electric VTOL aircraft. If you want details you will have to sign an NDA and stand in the que.
Hi friend can you please give me your comment in our data shit for our project of EVITOL that we develop ?
I feel like an artist without hands.
Lets just enhance the existing transportation by applying the vehicle with three dimensional usage that can be useful on the roads air and water. Aside from that the enhancements of establishment in order to adopt the said enhancements. Flight schools may start to consider the further adjustments how they can teach the peoples to adopt in fast pace so that we can achieve the goals as soon as possible.
Not the first, the first offered 1mil+ in prize money. Should have been ten mil. Or more.
I'm going to call my design "penguin", as just like a penguin, I don't think it can fly.
competition crap.. restricting designer to crappy tech on the market.. no thinking out of the box..i.e. better design edf etc
I would never give up a design for a mere 300 bucks. Lol I bet nobody even entered the contest
@Electric Aviation - I have another 2 (or 3) questions for you...
1. How should we treat canopy/windscreen weight? Being that these are (typically) made of plexiglass and are mostly non-structural, it would seem that the mass per unit area should not be the same as the composite material you have ascribed in your spreadsheet. Plexiglass is about 30% less dense than carbon composites (by volume), and a plexiglass windscreen can be made notably thinner than the structural walls of the airframe since they are not load bearing in the same way the airframe is. Considering this, how would you like us to treat the weight of the canopy/windscreen?
2. In the case that we have a lifting-body design and an open-cockpit, it would seem that the area of the "wing" coincides with the area of the cockpit, which cannot produce lift if it is an open cockpit . This makes calculating your effective wing area weird. Thus...
2.a. Should we omit the area of an open cockpit when calculating wing area and stall speed (meaning, we need a bigger wing)?
2.b. Conversely, should we include the area of a fully enclosed cockpit (full canopy, like the Martin Marietta X-24) when calculating wing area and stall speed (meaning, we can use a smaller wing)?
1.Please dont add the canopy weight. Consider it weightless.
2. The method given for calculating from the area is just for guidance. You can use your own method which is more accurate. For example volume of whole airframe can be calculated and multiplied by density.
Unless you have lifting body fuselage, please ignore the area of cockpit to calculate lift
Cool, i have sent in my designs. great stuff. cant wait for the next video and the other entries,
Got it!
@@ElectricAviation alright thank you for letting me know.
Great info motors and props and all!!!!
Really cool !!! Like in the lab....thanks
Glad you liked it!
evtol are nowadays still a joke, sadly
how hard is the rule about 150 kg battery? mines 153.... ads 3 to six km of range
Go for it
This is very interesting.
After submission and being selected , who owns the design & patent? Can an entry be more than one per individual? Do we have a contract to that effect?
Firstly this design competition is the level of high school project. It wont generate patentable ideas. Secondly, if someone does produce something that is patentable, they will keep the rights. I will be publishing their names with their design
@@ElectricAviation No problem with your format policies. One of my ideas for this is an air breathing hybrid aircraft with electric propulsion system utilizing different power source. Tnx , anyway.
This was a fantastic idea! Looking forward to seeing what people create! I sadly saw this video late in the game, so hopefully I'll still be able to meet the deadline to submit. Wish me luck! And if anyone is looking for someone to team up with, I am more than interested. Please reply to this comment to let me know.
I am sorry if I upset you but NON of these designs have any chance what so ever of becoming practical electric aircraft. There is a fundamental issue that makes them all potentially lethal. That is their inability to autorotate on motor failure. The tilt wing Osprey in service killed many people before the FIA dodged safety parameters and allowed Boeing to replace proper safety regulations with a total reliance on engine and tilt wing mechanism reliability. These idiotic electric designs are all ideas based on the Osprey tilt wing or even more basic scaled up multi rotor drones. THINK AGAIN
The objective of the challenge is to make people think about the design choices and the compromises they have to make. We are not looking to actually physically make an aircraft. This is an activity that is not completely based on arbitrary design, but considers constraints.
@@ElectricAviation Having been involved in aircraft design for over 40 years including consulting on the F35B cold lift fan, I fully understand the difference between basic ideas and the work that goes into aircraft design. Unfortunately I also advise government on EVs having been responsible for formula E and I get a little annoyed at the current grant laundering ideas being considered. There should be a committee set up to recruit assistance for governments to decide on projects presented to them, instead of making ridiculous knee jerk decisions based on a total lack of knowledge of the subjects.
I agree. As for the prize money for this challenge, its completely sponsored by myself, for my community on UA-cam, who are very excited about Electric Aviation and the possibilities it presents.
I myself am an enthusiast who grew up on Popular Science and marvelled on Engineering
My "Sky Scooter" is the right size, and more than meets the performance criteria, but it is hybrid with a small V-twin motorcycle engine in the nose that runs the generator. The electric motors and batteries provide the surge power for liftoff and climb-out, but you still can't beat petrol if you want cross-country cruise range and not just a sky taxi.
I might see if a pure electric version that meets your range requirements would be possible, but I have to go with the batteries we have, and not the ones I wish we had.
Do any Engineers want to team up? I have a Novel Design.
Wish I had seen this comment sooner. I am an aerospace engineer, and I'd be happy to collaborate. I have some ideas of my own as well. Perhaps we could bounce a few ideas around and come up with something? It's been 3 weeks, so perhaps you already have considerable progress on your own. Nevertheless, I would be willing to team up if you are.
I don't understand the battery capacity at cell and pack level, surely the pack level is the limiting factor in terms of weight? How many cells to a pack, please explain?
Hi, I will be publishing a video on Thursday to explain this. I cannot comment on the number of cells because there are so many cells to choose from, pouch, cylinderical and prismatic and all with different sizes. So this is just a high level design where battery weight will be used instead of number of cells
Also at the pack level because we have to add busbar, thermal management system and BMS
@@ElectricAviation Ok thanks
As the deadline is already past, when can we expect the winner's announcement? What if there is a design that does not comply with all the restrictions/requirements, but fulfills the criteria partially?
The next video will have the results
Hello Yogesh. do you have any idea to make evtol? please let us know!
@@bigflyair Yes, I do have some ideas. Please call me नव्यान्नव सदुसष्ठ एकोणनव्वद वीस चौसष्ठ
@Electric Aviation - 3 (or 4) questions for you
1. The spreadsheet doesn't specify any change to propeller thrust when you add a duct. Should we assume the thrust remains the same whether we add a duct or not?
2. The "Efficiency" table does not distinguish between large and small propellers. What is the threshold for a small propeller?
3. The "Efficiency" table does not specify what a "multi-EDF" design is compared to a "large/small ducted rotor" design. Can you please distinguish between these two categories?
3.a. As an example, If I have a 1m ducted propeller centered on each wing, and another 1m ducted propeller on the wing tips (4 propellers in total) would that classify as a multi-EDF, or a large ducted rotor design?
With the duct, if you look down the table, you can see the reduced amount of power you need for the same amount of thrust.
The efficiency has been factored in augmented L/D ratio chart
3. It would be large ducted rotor design
@@ElectricAviation Many thanks for the clarifications!
Great idea. This will be fun!
I think so too!
wow.. $300. I'm hoping he means RC aircraft- I'll just assume. so- around $1000 for all the motors, VFW's and batteries. $400 for the RC radio / receiver / servos. ENDLESS hours testing & designing the air frame. around $1000 material cost for building molds & laying up composite parts...
... and he's going to give me $300!? I think I'd rather go play slots- the odds are better. even though my calculous teacher said: "gambling is a tax on people with bad math skills".
a better idea? solve the riddle of building a battery pack / cells that can fly a 5 passenger vtoL craft 1200 miles... and then DON'T tell this guy. lol.
$300 is the prize money for the best design. You dont need to make a physical prototype
I have been waiting for this and I am hyped.
Good luck with the competition.
That said, I don't think a good VTOL can be designed to comply with these requirements.
The only way I see after listening to the video to formally fulfil the requirements is to make the aircraft
- very slow (just a bit above the stall speed)
- and unsafe (big non-redundant props)
If you want a better one, I suggest iterating on the requirements a little bit more.
I think its just an exercise to make people think in a certain manner. How would you make design compromises etc. Each year we will make the challenge more difficult and closer to what is required in an actual functional prototype.
@@ElectricAviation consider adding just one more requirement: that aircraft should still be controllable in VTOL after one propulsion unit failure. This requirement would influence the design heavily and the result would be closer to a real VTOL.
Awesomeness. I’m in !!!
Good luck!
Why you show my craft at 1:00?
Because it was already on public domain
@@ElectricAviationTag EDEA, or show my Name with the drawing, btw you should do this with the other designs you show in the video too. Was quite a bit of work .....Anyway, good Luck with your competition.
What if you are a business and already have designed one?
I am not a business. I am only in the business of education
@@ElectricAviation I think Design Count is wondering if established aeronautical engineering companies that have already developed a design may enter the contest. My guess is: yes, if they can prove that their design meets all the requirements...
