My team and I are stumped in a section of our design process. We are currently trying to estimate the gross weight of our designs (step 2.1.1.1). We have tools necessary for our design, (i.e. the Mathcad and Excel sheets as well as the Baseline CAD Models) but we don't know where to start. There are two different excel sheets that give weight estimations and we do not know which to use or how to get the specific inputs for them. Mathcad is also confusing us, as there are references made to FloEFD and if I'm not mistaken, we aren't using that software this year.
Basically, we were wondering how to go about performing the gross weight estimation and when to start using the Mathcad sheets.
Moreover, according to the workflow, after estimating the gross weight, we are to scale the model down so that our camera makes up 10-20% of the total weight. Does this mean we take the empty weight we estimated and resize it so that, for example, a 5 kg camera would be part of a 50 kg UAV?
Thanks in advance.
