Short description
Meco Rocket Simulator is a realistic physics game where you play as an underpaid rocket scientist working for Mecodyne to design and test rocket engines without regard for your safety.
About this game
Wire it. Fire it. Read the graphs. A rocket engine design sim with real physics. Drop pumps, injectors, valves and nozzles on a node graph, wire them up, set the numbers, and test fire. Every number you change answers back on the live graphs and in the 3D hardware. Twist a number, watch the engine answer Twist an injector orifice, and the chamber pressure curve responds in real time. Tighten the cooling channels and watch the thermal margin shrink. Reshape the nozzle and see what it does to Isp. Pump and turbine performance curves you can sample as you tune. Set four numbers, get a real nozzle The Thrust Chamber builds a real Rao bell contour and tiles the regenerative cooling channels for you, live in 3D. The Turbopump sizes its own shafts and gears. The supersonic flow field through your bell renders as a 3D volume and grays out past the point where the flow separates. Thrust comes from integrating that field, not from a lookup table. Author the startup, then light it Put every valve on a schedule: pumps spin up, valves crack open, the gas generator lights, in the order you set. Get the sequence right, and the engine runs nominal. Get it wrong, and the graphs tell you where. It's a sim that won't lie to you about the numbers on the graph. Every node is inspectable. Every graph is live. The engine model behind it is described in a publicly available research paper , with a DOI and all, so you can check my work. Three ways to play Missions (start here) Fourteen guided challenges, from "what's a model?" to recreating the Merlin 1D that flies Falcon 9. Senior engineer Miku Aoyama walks you through, deadpan, accurate, mostly patient. You don't need to arrive as an expert. You're an underpaid engineer at Mecodyne, the kind of propulsion company that ships rockets aggressively and has opinions about your eyebrows. On your first day, you accidentally fire up a Vulcain 1 on your coworker's workstation. The graphs come alive. The Vulcain runs. You probably shouldn't be doing this. That is Mission 0, and the missions build from there. Free build Skip the missions. Empty canvas, node-based editor, live graphs. Drop in components, wire them up, hit run, see…
