Solution Overview
Problem
Current propeller-driven propulsion engines are not unified across different classes of aircraft, such as propeller, rotary wing, and tilt rotor aircrafts, and lack efficiency in generating variable directional thrusts and lifts.
Innovation Solution
A propeller-driven propulsion engine in a pipe profile with rotating props and shafts, adapted from the Omni M-VAWT, featuring a sun rotor assembly, planet rotor assembly, carrier plate assembly, and airfoils assembly, with a controlled rotation and alignment mechanism, allowing for variable directional thrusts and lifts by actively controlling the angle of rotation and airflow of the planet airfoil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate propulsion engines are used for propeller, rotary wing, and tilt rotor aircrafts, then each aircraft type can be optimized for its specific function, but the overall system complexity and lack of unity across different aircraft classes increases
Solution Approach 1:
The patent implements a unified propulsion engine design that can operate in multiple modes (propeller mode, rotary wing mode, and tilt rotor mode) through a single integrated system. The engine incorporates both horizontal and vertical shafts with respective props, allowing it to function across all three aircraft classes without requiring separate specialized engines for each type, thereby achieving universality and multi-functionality.
2Productivity
If fixed wings are used in propeller aircrafts, then structural simplicity is maintained, but efficiency in generating variable directional thrusts and lifts is reduced
Solution Approach 1:
The patent replaces static fixed wings with dynamic rotary wings that can actively rotate and change orientation. The rotary wings mounted on vertical shafts can generate variable directional thrusts and lifts by adjusting their rotation and tilt angles, providing dynamic adaptability that fixed wings cannot achieve, thereby improving productivity in thrust and lift generation.
3Productivity
If vertical axis wind turbine configuration is used, then compact structure is achieved, but propulsion efficiency and variable directional control are limited
Solution Approach 1:
The patent merges the vertical axis wind turbine configuration with traditional propeller and rotary wing elements into a hybrid system. The engine incorporates both vertical shafts with props (for lift) and horizontal shafts with props (for thrust), combining the compact vertical axis structure with the propulsion efficiency and directional control of horizontal propellers, thereby achieving both compactness and high propulsion efficiency with full directional control.

AI summary
Pipe Props Rotary Wing of the present invention is a propeller driven propulsion engine in a pipe profile with props or propellers rotating in part as rotary wings around their shafts; the props and shafts are oriented lengthwise along the pipe; and the props in rotations propel directional air transversely through and across the pipe to generate variable directional thrusts and lifts in directions also transverse to the pipe. Pipe Props Rotary Wing is a variable thrusts and lifts propeller driven propulsion engine to unify all propeller driven propulsion engines for all propeller driven aircrafts, including: propeller aircrafts, rotary wing aircrafts or helicopters, and tilt rotor aircrafts. Pipe Props Rotary Wing in a pipe profile, with props rotating in part as rotary wings, is suitable as fixed wings replacements for propeller aircrafts and tilt rotor aircrafts. Been adapted from Omni M-VAWT or Omni Multi Axes-Vertical Axis Wind Turbine with modifications, Pipe Props rotary Wing as propeller driven propulsion engines are unified also with some vertical axis wind turbines.
