Optimal Huge Rotor RPM?

[TJRoh]

I want to build a very efficient helicopter so I wonder what the optimal RPM/RPS is for the huge rotor?

Also do I understabd it right that if the rotors max force is 200000 then I need 200000 in total engine power? No matter the RPM/RPS?

I'm using a huge rotor helicopter. 2 aircraft engines, one 1:3 gearbox. Flies perfectly at 30-35% throttle.
If lifting something up or towing, I usually go for 50-60 throttle. Never needed more so far.

Note that more blades your rotor have - better lift you'll get. Found out while experimenting with that helicopter. With 4 blades it needed over 70% throttle to fly.

Thanks! Which direction are your gearboxes? 3 turns of engines -> 1 turn of rotor?

For opimal performance you should use 8 blades rotors and UP gear. 1- to motor 3 - no blades. Arrows should be in th opposite directoion of power flow.

With this setup 1 large rotor and 1 small engine can lift supprisenly large weights. Or fly on the edge of stalling the motor.

Engines are surprisingly OP right now, and I expect them to be nerfed at some point. I'd avoid building a supposedly hi-powered vehicle, like huge heli, with just a small motor, so you won't need to rebuild later. However, with enough upshifting gearboxes now you can power almost any boat of heli propellers with small engine.

Building a CH-54 currently and with a huge rotor able to carry upwards of 2000 blocks currently.

Triple diesel engines for 60k each also seemed to be about 1800 blocks so 10% technically, and the 200k diesel does 10% of that.

This is using 6 blades tho, 8 blades does improve lift, and using a simple test with lifting a cart of weight blocks.

Thanks a lot for your help!
