Pump Research and Integration

Comp 2025	Payload	@Alison Thompson

Task Description

One of the designs we are looking into is a single or dual pump water collection and release system. We need to determine what pumps to use, what integration steps are needed to get this working with the rest of the drone, and integrate it into the rest of the payload design. This will include how we get water from the pick-up barrel into the pump and then into the drone’s water tank, and then from the tank to the delivery bucket.

The first part of this will be to collect a list of pump options, their specs (cost, weight, flow rate, voltage, current draw, one-way vs two-way, # of inlets, # of outlets, etc), then we will bring these options to comp-sync and discuss.

Next will come designing how this pump gets the water from the pick-up barrel, this will likely be a hose of some kind, but can be discussed.

Finally you will integrate this design into the drone’s water tank design, working with the person assigned to that task.

Initial Ideas

@Smile Khatri and I both found some options and listed them in this doc: AEAC 2025 Design Sprint

We were looking at computer water cooling pumps because of their high flow rate and small package, but if you have any other ideas feel free to explore them!

Can also look at valves like this for output, please look at a few options for these as well: https://www.aliexpress.com/item/1005003706956237.html
