Bates Grain Burn Rate Calculator 1.0

Bates Grain Burn Rate Calculator is a specialized tool for modeling and analyzing the burn behavior of BATES-style solid rocket propellant grains. Designed for students, hobbyists, and educators in experimental rocketry, it helps you explore how grain geometry and propellant properties influence burn rate, Kn, chamber pressure trends, and overall performance.

Key features:

• BATES grain modeling: evaluate diameter, core size, web thickness, length, and number of grains to study neutral, progressive, or regressive burns
• Burn-rate inputs: use propellant density and burn-rate coefficients to estimate burn time and surface area evolution
• Performance estimates: view indicative Kn and chamber pressure trends, mass flow, thrust profile tendencies, total impulse, and average thrust
• What-if analysis: quickly compare geometry variations, propellant options, and nozzle throat sizes to see their impact
• Units and outputs: switch between common metric/imperial units and export results for reports or coursework
• Visualizations: plot key parameters over time to understand how geometry changes drive performance

Notes:

• For educational and preliminary design use only; results are estimates and do not replace instrumented testing or professional review.
• Always follow applicable laws, safety codes, and best practices when working with rocketry.
