Motion Generating System Drag Reduction via Fluid Phase Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motion generating systems for crafts face limitations in achieving high speeds due to drag forces, as they rely on traditional propulsion methods that do not effectively utilize pressure reduction and density changes in fluids for thrust and lift.
Innovation Solution
A motion generating system that introduces a hot fluid or chemically reactive material into a target zone adjacent to a primary surface, creating a dynamic pressure reduction through heat exchange and implosion, which propels both the fluid and the object, reducing drag and enhancing thrust by manipulating fluid density and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional propulsion methods are used, then the craft can move through fluid, but drag forces limit the speed and acceleration
Solution Approach 1:
The patent changes the physical parameters of the fluid in front of the craft by introducing hot fluid that undergoes phase change, transforming the fluid from liquid to vapor state. This parameter change reduces fluid density and drag force, allowing the craft to achieve higher speeds by moving through a less resistant medium.
Solution Approach 2:
The patent utilizes phase transition of water to steam through heating. The introduced hot fluid causes water in front of the craft to vaporize, creating a low-density vapor region that reduces drag. This phase transition is the core mechanism for achieving drag reduction and speed enhancement.
2Force
If thrust force is increased to overcome drag, then speed can be improved, but energy consumption increases
Solution Approach 1:
The patent converts the harmful drag force into a beneficial propulsive mechanism. By introducing hot fluid that vaporizes water, the system creates pressure differential that generates thrust. The drag-reducing vapor region itself becomes part of the propulsion mechanism, allowing the craft to be pushed forward by pressure difference rather than requiring additional energy input.
Solution Approach 2:
The hot fluid serves as an intermediary substance that transfers energy to the ambient fluid, causing phase change. This intermediary mechanism allows indirect propulsion through pressure differential created by vaporization, rather than direct mechanical propulsion, potentially reducing energy consumption.
3Force
If hot fluid is introduced into the target zone, then pressure reduction and thrust are generated, but system complexity increases
Solution Approach 1:
The system utilizes ambient water as the working fluid, eliminating the need to carry large quantities of propellant. The hot fluid introduces thermal energy that triggers self-sustaining phase change of ambient water, which then provides both drag reduction and thrust generation. This self-service approach reduces system complexity by leveraging environmental resources.

Function Achieved in This Case
This system achieves significant thrust and reduced drag, enabling higher speeds and accelerations by leveraging pressure and density changes, potentially allowing for fuel-free flight and efficient propulsion in various environments.
Implementation Method 1
heat exchange between the hot fluid, the primary surface, and the adjacent fluid in and around the implosion zone
Implementation Method 2
If the gas is brought to a thermodynamic state where it undergoes a phase change to a liquid or solid state then most of the molecules attract together
Implementation Method 3
If a gas undergoes condensation on contact with a cooler surface then the partial pressure exerted by the condensing gas molecules is half of the pressure that would have been exerted on the surface
Implementation Method 4
there can be a subsequent rapid implosion as a result of condensation of the steam
Implementation Method 5
Fractional imbalances in this pressure on an object can result in very high thrust forces and accelerations
Implementation Method 6
generation of zones of reduced pressure and density in front of and above the craft allowing the craft to be thrust forward
Implementation Method 7
reduction of fluid density in front of the craft results in a reduction of frontal drag
Implementation Method 8
interaction between the driving fluid and the working fluid in the mixing zone develops a pressure reduction in the mixing zone to cause working fluid to be drawn from said source into the mixing zone and propelled towards the outlet

AI summary
A motion generating system for propelling and/or lifting a craft exploiting explosive and implosive processes, whereby a propulsive or lifting force on the craft arises from two sources: generation of a stream of fluids which imparts thrust to the craft; and generation of zones of reduced pressure and density in front of and above the craft allowing the craft to be thrust forward and lifted by ambient pressure on the rear and underside of the craft. Furthermore, reduction of fluid density in front of the craft results in a reduction of frontal drag allowing the attainment of higher speeds. The motion generating system may have other applications; for example, the motion generating system may be used to propel a stream of liquid in the manner of a pump.
