Title

Inverse-Propulsion Solar Sail System with Plasma Energy Harvesting and Directed Momentum Exchange

---

Technical Field

The present invention relates to space propulsion systems, and more particularly to non-propellant spacecraft propulsion, combining solar radiation pressure, solar wind plasma interaction, electromagnetic energy harvesting, and active momentum redirection.

---

Background of the Invention

Conventional spacecraft propulsion systems rely on stored propellant, resulting in limited mission duration, increased mass, and constrained maneuverability.

Existing alternatives include:

• Solar sails, which exploit photon pressure but lack active braking or energy generation capability.
• Electric propulsion systems, which require stored propellant and external power sources.
• Electric solar sails (E-sails) and magnetic sails (magsails), which interact with the solar wind plasma but are typically passive and do not harvest energy for active thrust modulation.

None of the existing systems provide a unified architecture capable of:

• harvesting energy from the solar wind,
• producing controllable braking forces,
• generating active thrust without onboard propellant,
• and dynamically managing momentum exchange with the heliospheric environment.

---

Summary of the Invention

The invention discloses an Inverse-Propulsion Solar Sail System (IPSS), herein referred to as HelioSail, which integrates:

1. A photonic solar sail for continuous radiation-pressure propulsion.
2. An electromagnetic plasma-interaction structure (electric sail, magnetic sail, or hybrid).
3. A plasma energy harvesting subsystem converting induced plasma currents into electrical energy.
4. A power processing and storage unit.
5. An active ion re-acceleration and expulsion subsystem for directed momentum exchange.

By extracting kinetic energy from the solar wind plasma, the system generates electrical power while simultaneously increasing momentum transfer opposing the plasma flow, producing a controlled inverse propulsion (braking) effect.

The harvested energy may be selectively reused to actively re-accelerate captured ions, producing directed thrust without onboard reaction mass.

---

5. Active Ion Re-Acceleration Subsystem

A portion of intercepted solar wind ions is selectively accelerated using electrostatic or electromagnetic acceleration grids and expelled in a controlled direction.

The resulting momentum exchange produces net thrust aligned with the desired trajectory vector.

---

6. Operating Modes

Cruise Mode

Passive solar radiation and plasma interaction provide continuous thrust with minimal power consumption.

Brake Mode (Inverse Propulsion)

Energy is extracted from the incident plasma flow, increasing momentum transfer opposing spacecraft motion and producing controlled deceleration while generating electrical power.

Boost Mode

Stored or harvested energy is used to re-accelerate plasma ions, producing thrust without onboard propellant.

Detailed Description of the Invention

---

1. Sensor Fusion Layer

The system collects data from:

• plasma density, velocity, and temperature sensors,
• electric and magnetic field sensors,
• solar irradiance and spectral sensors,
• inertial and attitude sensors.

These data streams are fused into a state vector representing the spacecraft–heliosphere interaction.

---

2. Predictive Modeling Layer

An onboard AI module implements one or more of:

• machine learning regression models,
• recurrent neural networks,
• physics-informed neural networks (PINNs),
• hybrid AI–physics models.

The module predicts future plasma and photonic force distributions over defined time horizons.

---

3. Control Policy Generation

Based on predicted states, the AI generates optimized control policies for:

• tether voltages,
• magnetic field configurations,
• photonic sail reflectivity distribution,
• ion collection and emission rates.

---

4. Adaptive Learning and Update

The system continuously compares predicted vs observed outcomes and updates internal models, improving accuracy over mission lifetime.

---

5. Autonomous Safety and Resilience Mode

In response to predicted extreme solar events, the system preemptively enters protective configurations, redistributing loads and reducing exposure.

---

Advantages of the Invention

• Anticipatory rather than reactive control
• Increased stability and efficiency
• Enhanced energy harvesting optimization
• Autonomous long-duration operation
• Reduced ground intervention
• Robustness against heliospheric variability
