Rocket Plume Excavation for Deep Frozen Volatile Mining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mining frozen volatiles in space, such as lunar ice, are inefficient due to high mechanical complexity, depth limitations, and maintenance requirements, and lack the ability to effectively excavate deep deposits and process resources quickly and economically.
Innovation Solution
The use of a rocket engine plume to create a controlled pressure environment, generating a deep cratering effect through standing shock waves, which allows for efficient excavation and processing of frozen volatiles by heating and releasing them from the regolith, and subsequent condensation using a collection manifold and cold trap system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional drilling methods are used to mine frozen volatiles, then mechanical complexity and maintenance requirements increase, but excavation depth and efficiency are limited
Solution Approach 1:
The patent replaces traditional mechanical drilling systems with a rocket engine plume-based thermal excavation system. The rocket plume uses thermal energy and shock waves to melt and excavate frozen volatiles, eliminating complex mechanical drilling components and reducing maintenance requirements while increasing mining depth and efficiency
Solution Approach 2:
The system changes the operating parameters by using controlled pressure environments and varying rocket engine thrust levels to create different plume characteristics. This allows the same system to adapt to different mining depths and volatile concentrations without mechanical reconfiguration
2Length of stationary object
If traditional drilling methods are used, then the system can operate with simple equipment, but it cannot effectively excavate deep deposits
Solution Approach 1:
The rocket engine can operate continuously or in repeated pulses to progressively deepen the excavation crater, allowing sustained access to deep volatile deposits. The system maintains continuous thermal action on the regolith, preventing the need to retract and reposition equipment as depth increases
3Length of stationary object
If the rocket engine is positioned closer to the ground to increase excavation depth, then the plume energy is more concentrated, but the collection manifold must handle higher pressures
Solution Approach 1:
The system dynamically adjusts the rocket engine thrust level and pulse duration based on real-time pressure sensors in the collection manifold. When the manifold approaches maximum pressure capacity, the system reduces thrust or extends pulse intervals, allowing the engine to be positioned close to the ground for deep excavation while maintaining safe operating pressures
4Area of stationary object
If the plume is allowed to expand freely, then the excavation area is larger, but the energy concentration at the target decreases
Solution Approach 1:
The rocket engine operates in periodic pulses rather than continuous flow. Each pulse creates a concentrated plume that penetrates to the target depth, then pauses to allow volatiles to be collected and pressure to equalize. This periodic action maintains high temperature concentration while achieving sufficient excavation area through repeated passes
