Problem
Existing pulsed plasma engines face limitations in efficiently utilizing non-combustible gases to generate explosive pressure pulses for driving output members, such as turbines or pistons, due to inefficiencies in gas ionization and plasma confinement.
Innovation Solution
A pulsed plasma engine design where non-combustible gas is ionized to form a plasma within an explosion chamber, an electrical pulse is applied to heat the plasma, and the pulse is turned off to produce an explosive pressure pulse, which is then confined and directed by a magnetic field towards an output member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If non-combustible gas is ionized and heated by electrical pulse to produce explosive pressure pulse, then power output is improved, but energy loss increases due to inefficiencies in gas ionization and plasma confinement
Solution Approach 1:
The patent replaces conventional thermal combustion with plasma physics mechanisms. Electrical pulses ionize non-combustible gases (nitrogen, oxygen, air) to create plasma, which then generates explosive pressure pulses through electromagnetic heating rather than chemical combustion. This substitution enables efficient energy conversion to mechanical work while avoiding the energy losses inherent in traditional combustion processes
Solution Approach 2:
The patent utilizes extreme parameter changes in the plasma state, with temperatures reaching 1,000 to 100,000°C. These dramatic temperature variations enable the plasma to achieve sufficient pressure for driving output members while maintaining high energy conversion efficiency. The electrical pulse duration and intensity are carefully controlled to optimize the balance between power output and energy loss
2Productivity
If plasma is confined by magnetic field to direct pressure pulse toward output member, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent employs magnetic fields as a non-contact confinement mechanism analogous to fluid pressure systems. The magnetic field acts as a virtual container that directs the plasma-generated pressure pulses toward the output member (turbine or piston) without physical contact, thereby improving productivity while avoiding the mechanical complexity of traditional containment structures
Solution Approach 2:
The magnetic field serves as an intermediary between the plasma and the output member. It transmits the energy and directional force from the plasma pressure pulse to the output member without requiring direct physical interaction, simplifying the overall system architecture while maintaining high efficiency in energy transfer
