SkyersJet said:New Prototype
- Wider shaft to prevent flexing
Drive shaft secured at both ends to prevent vibration
Washout added to blades
Duct lengthened to allow air to accelerate
Thinner walls and shorter screws to save weight
Narrower gearbox to not obstruct air
Stators are now aerofoil sections
Nylon blades
Respected sir, please tell me how much rpm required to get 18kg thrust...?Hi, thanks for your interest! All of the data is summarised at the end of my videos. In the first video (thrust test 6) I recorded 20kg thrust at 7712W. In the second video (thrust test 8 ) I recorded 18.7kg @ 7471W. NB: Different scales were used for both tests + I think that the batteries were sagging by the time I switched scales so I don't know which result is more valid.
Respected sir please provide me it's rpm details when it reaches at 18kg thrust. @ 7200kw.Seriously impressive project, might as well use it to propel a bike
But unless your nylon is higly CF/GF-filled, it is not that much stiffer than petg in my experience, so you'll still have problems with blades contacting the shroud at high RPMs I suspect. They might *survive* it though, but this is still not very nice...
Using CF/GF filled filament (not nessesarily nylon, CF petg works well according to my tests, to promote epoxy adhesion) and carefully gluing strips of uni CF to stiffen the construction over it will work, but balancing it would be a nightmare (I think it was already suggested).

Hi SkyersJetHmm must be my browser.
circular intake gave 5.7kg @1492W and the elliptical one gave 5.8kg @1439W
