turbopushues
Turbopushues are a class of hypothetical propulsion devices described in speculative engineering and theoretical discussions as compact, high-thrust propulsion systems that accelerate a working fluid through a turbine-driven cycle to produce thrust. The name combines turbo- with push, highlighting rapid exhaust acceleration. In proposed designs, a turbopushue consists of a turbine, a compressor, a power source, and a nozzle. Energy delivered by the power source spins the turbine, which drives the compressor and raises the pressure of the working fluid. The fluid then expands through a nozzle, creating thrust. Depending on the implementation, the energy source may be chemical propellant, electrical power from an onboard generator, or a direct energy input such as a nuclear or solar source. Some concepts envision closed-cycle operation with a separable energy loop to avoid direct intake of atmospheric oxygen.
Compared with conventional jet engines or rocket engines, turbopushues are theorized to offer higher thrust-to-weight ratios
