Direct-Coupled Dynamic Torque Reactor

The Direct-Coupled Dynamic Torque Reactor (DCDTR) is a proposed propulsion architecture in which an internal-combustion or other thermal converter is mechanically coupled to a controllable motor-generator but decoupled from wheel speed. A DC electrical bus, traction motors, and one or more storage substrates mediate the path to the wheels. The principal design object is therefore not a mechanical gear hierarchy but a controlled energy-and-torque system coordinating generation, storage, traction, thermal state, emissions, and mission demand. The proposal combines several ideas: stabilized engine operating regions; fast generator-torque control; multi-timescale storage; wheel-level electric traction; state estimation; constrained energy management; and an explicit admissibility layer for safety, component limits, emissions, and degraded modes. Its strongest novel contribution may be the integrated governance and explanatory architecture rather than any single hardware element. Similarity to series-hybrid and range-extender topologies must be treated as a prior-art and identity question, not answered by terminology. This revision separates physical state, control input, disturbance, parameter, and output variables; distinguishes a constraint set from its controlled viability kernel; repairs the mission objective; bounds the programmable-inertia analogy; separates realizability, control feasibility, comparative benefit, and constitutional-reframing claims; and adds safety, fault, empirical, GMB/GSM, and realization-funnel surfaces. No engineering or external literature validation was performed.
