Description

Specifications:Operating Pressure: 400,000 Pa (4 bar)

Nozzle Diameter: 12 mm

Estimated Mass Flow Rate: ≈ 0.45–0.5 kg/s (calculated using Bernoulli flow equation)

Spray Range (approximate): 12–18 meters depending on wind and elevation

Arm Torque (from CFD simulation):

Peak torque: ~2.4 N·m

Operating torque around Y-axis: ~2.0–2.4 N·m

Spring Constant Used:

~21.14 N·m/rad (≈ 369 N·mm/deg)

Return Time of Arm: ~0.025–0.05 seconds

Arm Mass: 233 g

About the Design:This is a functional concept of an impact model where water flow drives a spring-loaded arm, incrementally rotating the body.

Designed in SolidWorks

Fluid flow validated using SolidWorks Flow Simulation

Realistic water-jet behavior modeled to calculate torque

Quarter-circle deflector & angled jet diverter ensure smooth motion

What’s Missing (and How You Can Help!):Due to limited time, the following elements are functional placeholders:

Cam and follower mechanism (for sweep control)

Ratchet gear + pawl system (for incremental barrel rotation)

If you have experience with cam/ratchet design, your input is highly appreciated!Feel free to remix, review, or improve the mechanisms — just tag me or share it back!

Thanks!If you’d like to bring this design into reality — I’d be glad to help guide you through the build process.
