Ok, I've done some more thinking; here's what I've come up with.
A high quality APF (All Plastic Fiber) cable of some radius has an attenuation of about .15 db/m
Since attenuation is defined as ## att = 10*log(power_f/power_i),## my power transmission would be about 97% per meter.
For 1kw of...
Hmm.. I'm having trouble finding data on what kinds of irradiance fiber optics cables can handle.
My application will require something like 1-2kW of sunlight to be focused into the fiber.. I'm not sure if this is easily handled by most fiber cables or not.
I can see where bend radius...
I am trying to design a system that will carry light for illumination along a fiber optic cable. I see that there are many thicknesses of fiber optic cable - however I am unsure of the purpose of this. I've never heard of a 'density' of light that you can put into a cable - is there such a...
Ahh, that makes sense - I forgot to consider the air.
However, how would you calculate the energy per time unit?
Say the helicopter weighs 10N, to counteract that 1kg of air would have to be accelerated 10m/s^2 (F=ma).
Since K=1/2mv^2, would I take this in one-second chunks and say...
Take for example an electric helicopter - to keep it suspended motionless in the air takes a force from the propeller(s) equal to the force of mass times gravity.
I would like to know the energy required per unit of time to keep this helicopter in the air, assuming 100% efficiency.
I'm...
