Building a DIY ornithopter that flies like a hummingbird. It took over 4 months to design this mechanical bird, and with no knowledge about drone or rocket design, I was in over my head. One step closer to a real Dune Ornithopter.

Compressed air and oscillating wings has to be the most inefficient combination ever, but it's mighty impressive you got it to fly!!

[@inofarr8622]

Here you are ! I was thinking about you and maybe the fact that soda bottle can help him to get rid of the CO2 cartridge!

[@worksbydesign]

Its great to see the work you've done with compressed air engines, I might have to borrow some of those ideas in the future ;)

[@EsusGamer]

Agreed, using compressed air to oscillate the wings directly would be much more effective.

[@void3923]

you know its inefficient when when the king of inefficient propulsion Tom Stanton comments about it

Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. God said : Say, “We believe in Allah, and in what was revealed to us, and in what was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the Patriarchs, and in what was given to Moses and Jesus, and in what was given to the prophets from their Lord. We do not differentiate between any of them. And to Him, we surrender.” (2:136 / Translated by Community) Salam (Peace) ----------------

The statement at 15:18 is known as the "pendulum fallacy". You can't stabilize a hover by placing a mass under the lifting rotor, because as the plane tilts the vector of thrust tilts with it, and there's no restoring force. Tom Stanton has a good demonstration video of this.

Rocket pendulum? I’m guessing that the hose makes the bird dive harder, pointing more sideways instead of being able to straighten out?

[@ELYESSS]

@@franklinmcLaughlin a rocket or a plane should always be heavier in the front to be stable

[@rogerrinkavage]

​@@franklinmcLaughlin i imagine it like balancing a broom vertically in your hand. You want the bristles (heavy part) to be at the top while you move the handle (light part) around to adjust the balance. Having the inertia away from the force point you can rotate around the COM and maintain control. This is a messy explanation that I'm sure Wikipedia could do better 😂

[@scottpageusmc]

As a former Turbofan Test Engineer for Lockheed and Rolls-Royce at Stennis Space Center, I have one suggestion when working with turbines. You need stationary inlet guide vanes that direct the flow onto the rotar blades at an appropriate angle to produce the best entropy and enthalpy.

Back in the '90's when I was into paintball, the guns would freeze up when using CO2 unless you added an expansion chamber inline between the gun and the cartridge. The expansion chamber is basically just a thick aluminum tube to let the CO2 expand and absorb the temperature shock before it gets into the moving parts, sort of like a heatsink I suppose.

[@jeffwhitehead7990]

I was thinking about an expansion chamber to reduce freezing as well. Wondering too if the different materials (aluminum/print matrix) are an issue due to thermal contraction rate.

Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones.

Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?"

Tom Stanton concluded that using pressurized plastic bottles is more economical by weight than CO2 cartridges when making his air motors, maybe try modifying it for one of those? He explains in his most recent video that 1 2l plastic bottle holds 14x the air of one CO2 cartridge and weighs 20g less.

​@@worksbydesignIf you don't want to do it with electricity and you don't have enough power from compressed air, then why not just use steam?

A quick question on the motor choice - why go from compression to rotation to reciprocating? Would compression direct to reciprocating be more efficient? @TomStanton has done a lot of work on creating a very efficient air engine - of course, you'd need power on the up and down stroke...

[@worksbydesign]

I suppose it was because I initially wanted it to work with a spring like a wind up toy. So I designed the wing mechanism around that rotating spring. Could be a weight saving and more efficient route to take your approach on the next design.

Thank you for taking the time to share so much.

[@mildsauce5019]

Just a note on the exhaust gas measurement: Without wings attached youre going to have significantly faster exhaust gasses. So while youre seeing 67 grams of thrust on the chat at 16:22 ... the exhaust gasses will provide less thrust in the combined system -- because, of course, the addition of the wings will slow down the exhaust gasses. Simply put: Im pretty sure the wings are providing more thrust than you expect.

[@stev231]

It seems with the plastic mechanism and leaking, that the pressure deforms the delrin and allows small gaps to form on the surface of the manifold. I would suggest using a recessed housing with some rubber gasket material or sealant. I'd also like to see a button release for the co2 like you were planning, it seems like when you finally pierce the cartridge you still need an extra twist to get full power, and that's wasted pressure you could be using for thrust. Fantastic editing, you really put a lot of work into this, and I feel that if you want to avoid wear on parts that oscillate, you'd be better trying to design with compliant mechanism techniques rather than letting the parts rub against each other.

Very nice project! One thought, you need an oscillating motion for the flapflap. Maybe its simpler to use a linear oscilation air pressure motor as energy source. Like the piston of a steam engine which is valve controlled pressurized from both sides alternating. Then you can transfere the motion only with linkages without rotary motion in between. One issue could be, that there would be no fly wheel to hold momentum in phases with no pressure...

(perhaps a mechanical dragonfly?)

[@shay1999d]

This is beautiful! Thank you

[@JamesAlexanderMartin]

As a piece of engineering, that little motor is just beautiful. If I had to make a guess about the compressed co2 issue on the 3d printed version, I would say it's quite likely because of the heavy texture of the 3d print. It is likely providing a large surface area for the ice crystals to form. You may have some success giving it some sort of treatment that will make a smoother surface. With FDM ABS prints, an atomised acetone treatment works a treat. However that looks like an SLA powder print maybe but there is probably some kind of solvent that would achieve the same effect.

[@chrisedwards3866]

Incredible work and problem-solving! Your skill and experience in this far outweighs any suggestion I can make, but I'll throw this in just in case. The gunk from the CO2 cartridges may be oil, as some cartridges have oil to lubricate whatever mechanism they attach to (often paintball guns, and your supplier may have simply re-branded that type). You may need food-grade CO2, which should not have those contaminants. It's also possible that the contaminants are from the hose supply instead, and just weren't noticed immediately. On the other hand, some small amount of lubrication might be needed for the system. Also, the gearing probably adds considerable weight while reducing efficiency. If it's possible to get the RPM you need by adjusting the motor size or properties, that might be helpful. But, I don't know how that would interact with the sizing need to control the CO2 flow rate to prevent the freezing. Finally, there is probably a way to get that figure-8 movement that hummingbirds use, and (completely guessing, but it seems right) that shape might be a way of efficiently redirecting energy instead of losing it in the back-and-forth motion, and it probably has aerodynamic benefits by better utilizing the 'angle of attack' of the wing. A 4-bar linkage can generate that movement - there's an 11-page published paper "Design and analysis of "figure-8" trajectory flapping wing mechanism based on crank rocker" (by Shan Tang, in 2022), and a 162-page master's thesis entitled "Design of a 'Figure-8' Spherical Motion Flapping Wing for Miniature UAV's", (by Zohaib Parvaiz Rehmat, in 2009), which probably cover the topic in great detail. I'm looking forward to the next video!

[@greyminded]

[@alextrujillo8861]

Dude this is so awesome! Nice job.

[@JMMC1005]

I thought it was an interesting choice to go with a rotary motor and then convert it to a flapping motion (with the cool, but ultimately inefficient linkages and gearbox). I think you might be able to get a much higher power / weight ratio by directly driving the wings with a piston based design. Something sort of along the lines of a double-acting steam engine, where the piston is driven in both directions. You'd need a double-acting design to avoid the necessity of a flywheel. You might need to get a little clever with your valve system however, as without a flywheel you'll need to ensure that there's no possibility of the piston getting stuck at either end of its travel. However, if you can get it to work you can likely shave off a bunch of weight and reduce mechanical losses.

[@flybywireless9717]

How about ditching the motor mechanism completely and having the co2 venting out at the wing tips (2 exhaust to each wing) timed through 2 micro switch valves (or a homemade rotor valve mechanism) to produce the flapping motion. The plumbing could be through fine hollow carbon rods, that are also used as part of the wings construction. Nice work Top Lad, with impressive persistence.

Awesome project dude, I was wondering if that black powder might be residual nylon powder from the MJF process that's being blown out of the binding material by the sudden high pressure + temperature change, which would gum up the system. Also having 63% of your thrust being rocket based is 100% legal ;P The way I see it, a hummingbird doesn't use compressed gas to move so it doesn't have to worry about exhaust, but yours does so it's just a side-effect. I look forward to seeing any progress you choose to make on it!

I turned 62 years old today, and this guy reminds me of how we were back in the seventies, eighties and early nineties. RESOURCEFUL, INSPIRED, EXTREMELY ENTHUSIASTIC, UNDAUNTED, FUN, OPEN, WARM, KNOWLEDGEABLE, EXPERIMENTAL, ADVENTUROUS DOERS! 😄👍👏

Yes, it also reminds me how we took all that inspiration, education and skill, and collectively ... voted n azis into parliament. Great success, with only more to come.
