so, i ordered these motors and esc https://www.alibaba.com/product-detail/8kw-watercooling-BLDC-motors-for-electric_60652252411.html?spm=a2700.7724838.2017115.108.67c9179apjm9wP
i know its from china, but if the kv and kw rating are as they advertise, then it should work pretty well.
the board i intend to shape from eps foam, then cover with carbon fiber.
the impeller itself will be 76mm diameter, with a 70mm pitch, made from carbon fiber. (luckily i have a small carbon fiber shop at my disposal) im going to machine a top and bottom aluminium mould. i would usually use pre preg carbon in the autoclave, but this time i will use dry carbon cloth, and inject epoxy resin into the mould.
the rest of the water jet will be made from a selection of laser cuts, some custom machined parts, and some off the shelf bearings and water seals. (luckily i also have a fabrication shop at my disposal)
personally, i think the thrust problem mathias was having was not down to the motor, but i think he needed a more diverging nozzle. i guess ill find out over the next weeks.
anyway, if anyone wants the designs/models etc to use for their own project, or to improve them some way, then i can upload them or email them or something
