Rocket anatomy, how model motors work, choosing a starter kit, and what to expect on launch day.
AvailableImpulse classes from A to O, thrust curves, and matching a motor to your airframe and mission.
AvailableRequirements, choosing your L1 rocket and motor, build considerations, and common failure points.
AvailableThe written exam, higher-power motors, and an introduction to dual-deploy recovery.
AvailableDescent rate targets, canopy sizing math, drag coefficients by chute type, and separation charge sizing — a reference used at every certification level.
AvailableReloadable and hybrid motors, dual-deploy in practice, structural demands, and the L3 documentation review.
AvailableHow oxidizer, fuel, and binder choice shape burn rate and thrust — and how additives change performance, conceptually.
AvailableStructural and aerodynamic considerations at high speed — stability margins approaching transonic and supersonic flight.
AvailableCompressibility effects, thermal considerations, and tracking/recovery challenges at altitude.
AvailableThe certification path (Modules 01–09) covers everything you need to fly. These modules go a layer deeper into the standard aerospace engineering behind motor and vehicle design — the kind of material found in any propulsion or aerodynamics textbook.
De Laval nozzle shape, choked flow, expansion ratio, and the thrust coefficient that ties them together.
AvailableCenter of pressure, center of gravity, static margin, and the aerodynamic basics behind Module 08's transonic discussion.
AvailableWhat OpenRocket, RockSim, RASAero II, and ThrustCurve.org actually do, and when you need which one.
AvailableThe standard propulsion efficiency metric — what it means, how to calculate it, and how it connects to the rocket equation.
AvailableHoop stress, burst pressure, safety factors, closure design, and the failure modes that connect design to assembly.
AvailableIgniter types by certification level, continuity checking, common failure modes, and launch controller basics.
AvailableWhere chamber pressure comes from, Kn as the key design ratio, grain geometry effects, and operating pressure stability.
AvailableHow oxidizers, fuels, binders, and additives shape burn rate and Isp — and how calorimetry and Gibbs minimization let us predict it all before mixing.
AvailableStart with Module 01 — no prior experience required.
