It may feel like I'm bluffing or downplaying the complexity of everything but trust me, it's not that hard. There is absolutely no innovation in almost 90% of those "UAVs" that we see a new company coming up with every other day. If no innovation then you don't also need the R&D or intellectual capital all together. This lack of R&D is same for everything from tube launched loitering munitions to quadcopters to fixed wing UAVs. Now couple that with the sudden surge in availability of cheap electronics for robotics and FPV hobby drones here in India. And that's all.What is up with the recent surge of Private companies pushing out bee drone and missile based weapons?
Did DRDO brought out some new policy of technology distribution and support?
depending on how much of the "insides" is indian ...this is can either be really fucking good to an okay achievementCont...

Ayan any reason why dual or quadrocoupled electric motors with dual concentric contra rotating shafts are not being used in drones? Something similar to belowIt may feel like I'm bluffing or downplaying the complexity of everything but trust me, it's not that hard.

You give me just one electronic engineer with basic, one software engineer with intermidate understanding, a lakh or two in capital and I'll give you an above average loitering munition. Because everything else is simply like LEGO piece waiting for someone to order online and just plug-n-play

Pranam to Mahalaxmi Ma.
Well other than obviously the increased cost there are few more things. And ultimately it's the question of what benefits you're getting and what cost?Pranam to Mahalaxmi Ma.
I really want some one to execute above idea. If I had money I would have atleast experimented with it.
I think for any decent electric motor manufacturing company (Which designs and manufactures (or sources parts based on inhouse design) should not be difficultWell other than obviously the increased cost there are few more things. And ultimately it's the question of what benefits you're getting and what cost?
Correct. You can have 2 or 4 stacked motors for 2 or 4 coaxial motors. Moreover. It can eliminate hydra armed design structures which some 16 rotors drones are using> In case of let's say Tu-95 you're using the same engine to drive two propellers but here two separate motors are doing that. So from a battery perspective it's no different than having two separate motors.
The idea is to use same small hub and rigid coaxial rotors advantage S 97 raiders are having. Drones have rigid rotors and with this design you will have small hub, increasing lift and reducing weight I guess> The rear propeller will always work in the aerodynamic "shadow" of the front. So whatever 5-6% percent efficiency you might get from this coaxial arrangement would be pretty much brought to zero.
Correct. Or simple mule drones can employ to increase their lift and altitude(!?) Capability with better weight management.And as for advantages, I can only of two application where this arrangement can really shine.
> A coaxial helicopter type UAV. Instead of using one motor for main rotor and one for tail you're now using both for main rotor. Also as it's just a simple hollow shaft instead of complicated gear system as used on things like Ka-52s, it's both cheaper and more efficient.
> Another is a very niche application of where you need more power but the cross section is limited. To be specific, a tube launched UAV. You can't have multiple motors as everything should be constrained by the small tube diameter and even there the space would be bit tight as you'd be also needing some space to accommodate the wings in folded position.
