Abstract

The rapid proliferation of satellite constellations has necessitated a paradigm shift in orbital mechanics and propulsion efficiency. This poster presentation details the development and simulation results of a hybrid electric propulsion system designed specifically for Low Earth Orbit (LEO) sustainability challenges. As a leading hub for aerospace innovation, Japan Tokyo serves as the critical testing ground for these next-generation technologies. Our research focuses on optimizing specific impulse while minimizing space debris generation, aligning with international guidelines advocated by the Japanese Aerospace Exploration Agency (JAXA). The findings suggest a 25% increase in operational lifespan compared to traditional chemical thrusters, offering a viable path toward sustainable orbital infrastructure.

Introduction

The aerospace engineering landscape is currently undergoing a transformative phase. With the increasing congestion of LEO, the role of an Aerospace Engineer has evolved from mere vehicle design to comprehensive lifecycle management. In Japan Tokyo, this evolution is particularly acute due to the region's strategic position in global satellite communications and Earth observation networks. The primary objective of this study is to address three critical issues: fuel efficiency, collision avoidance capabilities, and end-of-life deorbiting protocols.

Traditional bipropellant chemical engines suffer from low specific impulse (Isp), requiring large fuel reserves that limit payload capacity. Conversely, pure electric propulsion systems offer high Isp but lack the thrust-to-weight ratio required for rapid orbital transfers. By integrating hybrid systems, we aim to leverage the best attributes of both technologies. This research is situated within the broader academic discourse emerging from universities and research institutes in Japan Tokyo, fostering a collaborative environment aimed at solving complex aerospace challenges.

Methodology

The methodology employed in this study combines computational fluid dynamics (CFD) with empirical data gathered from ground-based tests conducted at facilities near Japan Tokyo. The hybrid system under investigation utilizes a micro-thruster array powered by solar-electric propulsion for station-keeping, augmented by cold-gas thrusters for maneuverability.

• Simulation Environment:We utilized proprietary software developed in collaboration with aerospace partners in Japan Tokyo to model plasma flow dynamics within the hybrid chamber.
• Data Collection:Aerospace Engineers from our team collected over 5,000 hours of simulation data, focusing on thrust vector control and thermal dissipation rates.
• Metric Analysis:We evaluated performance using normalized specific impulse and thrust density metrics. The baseline for comparison was the standard Hall Effect Thruster currently used in many Japanese satellite platforms.

The rigorous testing protocols followed here reflect the high standards expected in aerospace engineering, ensuring that any proposed system meets the stringent safety and reliability criteria required for operation in the sensitive orbital environment surrounding Japan Tokyo.

Results and Discussion

The results indicate a significant performance advantage for the hybrid system. Specifically, the specific impulse reached values of 2,800 seconds during electric mode operations, compared to 1,500 seconds for the chemical backup thrusters. This efficiency gain translates directly to extended mission durations.

Furthermore, the thermal management system proved effective even under continuous operation cycles lasting 48 hours. Thermal imaging analysis showed that no component exceeded safe operating temperatures, validating the material choices used in the prototype construction. These results support the hypothesis that hybrid propulsion is not only feasible but superior for long-duration LEO missions.

Conclusion

This poster presentation underscores the critical role that advanced propulsion systems play in the future of aerospace engineering. As we look toward the next decade, the integration of hybrid electric technologies will be paramount for maintaining sustainable access to space. The work presented here, developed within the vibrant academic and industrial ecosystem of Japan Tokyo, provides a solid foundation for future satellite designs.

We recommend that further funding be allocated to full-scale prototype testing in orbit. Additionally, we call for greater collaboration between aerospace engineers globally to standardize debris mitigation protocols. The success of this project highlights the potential of Japan Tokyo as a leader in sustainable space technologies, setting a benchmark for international aerospace engineering standards.
