I'm working on some software that helps you select components (batteries, ESCs, motors, propellers) for a quadrotor/airplane/hybrid/generic UAV given a particular mission. It's basically ecalc in reverse with some optimization. I'm hoping it will be used by both beginners and experts to select parts or to validate part selections. I've been at this hobby for a few years and I still can't really find any tools (except ecalc) to validate any of the choices that I make for choosing parts.
Anyway, I'm at the point now where I could use some input from you all to help validate that the tool is working. I've been scouring the internet trying to find posts but I'm mostly finding quads, which is fine, but I'm hoping to add other vehicle types to the validation list - that said, I definitely won't reject additional quad data :) The claims I'm finding are matching pretty well so far.
Here's what input I'm looking for from you all:
Do you think this would be a useful tool for you? If no, why not?
Are there options/inputs/outputs that you'd like to see?
Post some of your max/average flight times including:
- which battery you use (# cells, capacity, discharge rating) and how far you discharge it (% or mAh)
- props (model or material, diameter, pitch)
- motors (KV ideally)
- the gross or component weights of your hex/quad/tri/airplane/whatever
- size of any wings and whether or not they tilt or are fixed to the body
- payload including fpv gear, anything else power-thirsty and/or heavy
Basically the more details here the better.
Here's a bit about what the software does. Lets say for example you want a quadcopter that will hover for 15 minutes that can carry a 1000 g camera. You input some things like:
min desired flight time
min/max total weight
min/max motor KV
min/max prop radius and pitch
min/max # motors
min/max# blades per propeller
flight mode (hover, cruise, mixed)
and a bunch more optional inputs
For each type of battery (right now 2S-6S), it tries to calculate the minimum mass of a vehicle that can accomplish the mission by using blade element momentum theory and some looping logic. It tries to predict the weights of all the components that would be required - motors, ESCs, battery, propellers, chassis, wiring, etc. It also tells you which class of motors (KV, weight) will be able to do the mission, how big of a battery (capacity and cell count), which props (radius, pitch), how much current it will take, etc. If it doesn't find a feasible combination of parts, it outputs the closest and lightest match. Plus a bunch of other stuff.
Looking forward to your comments!
