Solution Overview
Problem
Jet aircraft propulsion systems generate significant heat energy that is largely dissipated without being recaptured for useful work, leading to inefficiencies and increased weight from mechanical power generation systems.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional alternators are used to generate electrical energy for the jet propulsion system, then the electrical power needs are met, but the mechanical load and weight of the propulsion system increase
Solution Approach 1:
The patent converts waste heat energy from the jet propulsion system into useful electrical energy using thermoelectric generators. The heat that would otherwise be dissipated is now harnessed to generate electricity, reducing the need for mechanical alternators and thereby reducing weight while meeting electrical power needs
Solution Approach 2:
The patent replaces mechanical alternators with thermoelectric generators that convert thermal energy directly to electrical energy without moving parts. This substitution eliminates the mechanical load associated with traditional alternators while providing the necessary electrical power
2Loss of energy
If waste heat energy is dissipated without recapture, then the propulsion system operates simply, but energy efficiency is reduced
Solution Approach 1:
The patent transforms waste heat energy into useful electrical energy through thermoelectric conversion. The heat that was previously lost is now converted into a beneficial resource that powers auxiliary systems, improving overall energy efficiency
Solution Approach 2:
The thermoelectric generators are integrated into the existing propulsion system structure, utilizing the waste heat that is already present. The system serves itself by converting its own waste heat into useful energy without requiring external energy sources

AI summary
An aircraft jet propulsion system is disclosed. The aircraft jet propulsion system may comprise a thermoelectric generator array (“TEG” array) coupled to a portion of the aircraft jet propulsion system, wherein the TEG array converts heat energy to electrical energy, and supplies power to the aircraft jet propulsion system, wherein the electrical energy is supplied to a power supply. The aircraft jet propulsion system may comprise an alternator that generates less energy than is required to power the aircraft jet propulsion system. The TEG array may supplement the energy generated by the alternator. The energy generated by the TEG array and the energy generated by the alternator may be sufficient to power the aircraft jet propulsion system and/or the electrical energy generated by the TEG array may be sufficient to power to aircraft jet propulsion system.
