RocketPhysHub

Rocket PhysHub: Interactive Rocket Propulsion & Orbital Mechanics Lab Rocket PhysHub is a comprehensive, self-contained study aid designed for students and enthusiasts delving into the fundamentals of rocket propulsion, orbital mechanics, and supersonic gas dynamics. Built as a code-only utility, it transforms complex aerospace engineering concepts into interactive, visual experiences. Core Features: Propulsion Lab (Fuel Mixer) Choose from five fuels (Liquid Hydrogen, RP-1 Kerosene, Liquid Methane, UDMH, Hydrazine) and four oxidizers (LOX, N₂O₄, H₂O₂, AP). Adjust chamber pressure, expansion ratio, throat area, and O/F ratio via intuitive sliders. The app instantly computes specific impulse (Isp), exhaust velocity, characteristic velocity (C*), thrust coefficient (CF), and chamber/exit temperatures, visualizing the impact of your parameters in real time. Orbital Mechanics Lab Input altitude, satellite mass, drag coefficient, and cross-sectional area to calculate orbital velocity, period, and atmospheric density. The lab models the exponential atmosphere and solar flux to determine drag force, daily altitude decay, and provides an animated reentry timeline for understanding orbital degradation. Gas Dynamics Simulator (Laval Nozzle) Visualize supersonic flow within a converging-diverging nozzle. Manipulate chamber pressure, temperature, specific heat ratio (gamma), throat/exit diameters, and molar mass. The simulator plots pressure, temperature, Mach number, and velocity profiles along the nozzle axis, complemented by a continuously flowing particle field for intuitive understanding of isentropic flow. Privacy & Educational Focus: Rocket PhysHub is strictly an educational tool. All calculations run locally on your device—no network connection, accounts, or ads are required. Please note that the formulas employ simplified idealizations (frozen flow, exponential atmosphere, isentropic relations); results are illustrative and not intended for actual engineering design. The app contains no real-money transactions, gambling, or in-app purchases, focusing solely on learning.
