Solution Overview
Problem
Current ballistic missile defense systems face challenges in accurately intercepting maneuvering targets due to limited control schemes during the terminal phase of flight, requiring advanced propulsion and maneuvering systems that can provide axial and divert thrust to effectively respond to dynamic environments.
Innovation Solution
The integration of axial thrusters and divert thrusters within a common propellant distribution manifold, allowing for precise control and increased maneuverability, enabling the interceptor to maintain a line-of-sight with the target while providing axial and lateral thrust, thereby enhancing velocity, range, and acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional control schemes with single-source thrust are used during terminal phase, then system simplicity is maintained, but the interceptor cannot effectively respond to maneuvering targets
Solution Approach 1:
The propulsion system is segmented into two independent thrust sources: axial thrust generators for forward propulsion and divert thrust generators for lateral maneuvering. This segmentation allows each subsystem to be optimized for its specific function while collectively providing enhanced adaptability to maneuvering targets without excessive overall complexity.
Solution Approach 2:
The dual-thrust propulsion system provides multi-functionality by enabling both axial acceleration for range extension and divert thrust for lateral course correction. This universal capability allows the interceptor to respond to various target maneuvers (both maneuvering and non-maneuvering) using a single integrated system rather than requiring multiple specialized systems.
2Manufacturing precision
If axial and divert thrust are integrated in a common propellant distribution manifold, then control precision and maneuverability are improved, but system complexity increases
Solution Approach 1:
The axial and divert thrust systems are merged into a common propellant distribution manifold that shares propellant storage, pressurization, and distribution infrastructure. This merging reduces the number of redundant components compared to completely separate systems while maintaining the ability to independently control axial and divert thrust for precise maneuvering.
Solution Approach 2:
The propellant distribution manifold incorporates dynamic flow control mechanisms that can independently regulate propellant flow to axial and divert thrust generators based on real-time guidance commands. This dynamic control capability enables precise maneuvering by adjusting thrust vectoring in response to changing target positions and relative velocities.

AI summary
Embodiments of a propulsion and maneuvering system that may be suitable for use during a terminal phase in an interceptor are generally described herein. The propulsion and maneuvering system may include one or more axial thrusters to provide thrust along axial thrust lines that run through a center-of-gravity of the interceptor and a plurality of divert thrusters to provide thrust in radial directions. The combination of divert and axial thrusters may allow the interceptor to respond to a maneuvering target and may allow the interceptor to increase its velocity along a line-of-sight (LOS) to a target to change target impact/engagement time.
