Personal coaxial heli

[@MrDavidkellman]

Good job

[@2010Barbon]

with that rotorhead configuration you will find it will jam itself to one side when under torque load.its a phenomana that happens you never see a flying helicopter with that system.

[@ericdvikingtvetc.1909]

I dont think it will fly man it doesnt have a swash plate and the rotor blade design is for gyro not for helicopter to make a lift.

[@supercobrapro7470]

That's why we never saw flying video

⚠️ Deus disse no Alcorão: 🔴 { Ó humanos, adorai o vosso Senhor, Que vos criou, bem como aos vossos antepassados, quiçá assim tornar-vos-íeisvirtuosos. 🔵 Ele fez-vos da terra um leito, e do céu um teto, e envia do céu a água, com a qual faz brotar os frutos para o vossosustento. Não atribuais rivais a Deus, conscientemente. 🔴 E se tendes dúvidas a respeito do que revelamos ao Nosso servo (Mohammad), componde uma surata semelhante à dele (o Alcorão), e apresentai as vossas testemunhas, independentemente de Deus, se estiverdes certos. 🔵 Porém, se não o dizerdes - e certamente não podereis fazê-lo - temei, então, o fogo infernal cujo combustível serão osidólatras e os ídolos; fogo que está preparado para os incrédulos. 🔴 Anuncia (ó Mohammad) os fiéis que praticam o bem que obterão jardins, abaixo dos quais correm os rios. Toda vez queforem agraciados com os seus frutos, dirão: Eis aqui o que nos fora concedido antes! Porém, só o será na aparência. Aliterão companheiros imaculados e ali morarão eternamente. } (Alcorão _ 2 : 21-25 )

How can your coaxial heli change the angle of the blade sir ? there is not angle of attack the heli can't fly !

[@kareyriggs1018]

Redesign or stay earthbound. No swash,no grease on counter rotation gears,common bolts no safety wire,single steel chain drive when standard avio. Is geared belt

[@sarcamahardika]

Good job👍👏

[@Eliecer140]

Perfect...

[@tomthompson7400]

thats a mincer ,,, first it will mince the blades , then you , the only thing left at the end will be the truck chassis its built from ,,, for the love of everything holly dont go any further with this idea. take up chain saw juggling , its safer.

What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him

Exactly... they are WAY too close together. "Blade coning" alone will cause this system to fail catastrophically... and with you in it. Take a look at any Russian coaxial helicopter. The blades are separated by FEET... not inches!!!

[@artscrafts6616]

does the air blowing from the top rotor affect the bottom rotor at that height? Above a feet

[@rustie61]

@@artscrafts6616 The "air" is not the problem. The two rotor discs are far too close to avoid contact as the rotors flex during all the various control inputs. One abrupt input would immediately crash the blades, and your but right along with it...

[@artscrafts6616]

@@rustie61 okay I got the point.. Don't you think that the air that's blowing on the bottom blade won't affect the performance?. If it doesn't why so ?. M just asking just a little curious.

[@rustie61]

@@artscrafts6616 If, for whatever reason, both blades were spinning in the same direction... parallel (one on top of the other), or skewed, it could cause some aerodynamic irregularities, but counter rotation takes most, if not all of that out. The bottom blade in a CR rotor wash may actually become more efficient during hover, requiring less pitch for the same lift... but that again depends on the top to bottom separation. The farther apart, the less the effect. Of course, the closer they are, the chances of a collision during independent blade movements becomes the critical aspect I would not want to test. Then, there is "Translational Lift", which makes the entire blade disc more efficient at about 25 KTS (the entire rotor disc then becomes a "wing" of similar area). Of course, if you want to climb fast, allow the nose to rise some, and just add power (pull pitch = Collective). You will rocket upward! Although, I would assume that TL could act slightly different with a CR rotor system. The small CR rotor "XRON" I've flown seemed lazy during TL, but I never flew it very fast (the differential tip "drag plates" made for sloppy Tail Rotor/Yaw control compared to conventional tail rotors on MD500's or JetRanger's)...
