Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional propulsors are used, then the structure is simple, but the ability to control thrust vector and moment in full solid angle range is limited
Solution Approach 1:
The propulsor is divided into multiple independent flow passages (at least four), each equipped with its own controllable pressure unit and nozzle. This segmentation allows independent control of thrust in different spatial directions, enabling full solid angle control while maintaining manageable structural complexity through modular design
Solution Approach 2:
The pressure units in each flow passage are made controllable and reversible, allowing dynamic adjustment of pressure differential to control the direction and magnitude of working fluid flow. The nozzles are also made controllable to deflect the exhaust jet, providing dynamic adaptability for thrust vector control in any spatial direction
2Ease of operation
If controllable pressure units and nozzles are added to achieve full solid angle control, then the maneuverability is improved, but the device complexity increases
Solution Approach 1:
Each flow passage is designed as a universal module containing a pressure unit and nozzle that can independently generate and control thrust in any direction. This multi-functional modular design allows the same structural pattern to be replicated across multiple passages, reducing overall system complexity while achieving full solid angle maneuverability
Solution Approach 2:
Multiple flow passages are interconnected through a common joint chamber that serves as a shared working fluid reservoir and pressure equalization space. This merging of multiple independent control systems through a common chamber reduces the number of separate components needed while maintaining the ability to independently control each passage's thrust
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The propulsor achieves enhanced maneuverability and effectiveness by controlling the direction and value of thrust and thrust moment within a full solid angle, regardless of its spatial orientation, providing improved propulsion in three-dimensional mediums.
Implementation Method 1
Each of the passages includes a controllable pressure unit creating a pressure differential, thereby controlling the direction of the working fluid flow
Implementation Method 2
The nozzles in the flow passages can be independently controllable and adapted to controllably deflect a working fluid exhaust jet
Implementation Method 3
a jet flow propulsor using gas or liquid from the environment the propulsor is in as a working fluid
Implementation Method 4
Each of the passages is connected by one end thereof to the joint flow chamber whereas another end of each of the passages is in fluid communication with the environment and includes a nozzle

AI summary
A jet propulsor, for use in vehicles or other devices moving in a three-dimensional gaseous or liquid medium such as air or water, has a joint chamber and at least four flow passages which are connected to the chamber with one of their ends, have independently controllable reversible pressure units inside, and are provided with independently controllable nozzles on their other ends. The propulsor pumps gas or liquid from the environment through itself and, because of reaction forces, provides for simultaneously and independently controlled thrust and thrust moment in terms of their value/strength and direction. Spatial control of the thrust vectoring and conditional thrust moment vector can be provided for in the spatial range of a full solid angle.
