Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed wings or rotative surfaces are used for lift, then the aircraft can achieve flight, but the centre of pressure creates a rapid tilting moment that reduces stability
Solution Approach 1:
The aircraft is divided into functionally independent segments: the fuselage for housing, the rotative wing surface for lift generation, and separate stabilizing surfaces for control. This segmentation allows each component to perform its specific function without interfering with others, resolving the stability-maneuverability contradiction by isolating the lift-generating function from the stability-control function.
Solution Approach 2:
The invention introduces a new dimension of control by allowing the rotative wing surface to rotate independently around its spanwise axis in addition to its normal rotation for lift generation. This additional degree of freedom enables independent control of lift and attitude, allowing the aircraft to maintain stability while achieving maneuverability through multi-axis rotational control.
2Stability of the object's composition
If stabilizing surfaces are placed at the tail to oppose destabilizing forces, then flight stability is improved, but the aircraft complexity increases
Solution Approach 1:
The rotative wing surface serves multiple functions simultaneously: it generates lift through rotation, provides stability through its gyroscopic properties, and acts as a control surface through independent rotation around the spanwise axis. This multi-functionality eliminates the need for separate stabilizing surfaces at the tail, reducing aircraft complexity while maintaining stability.
Solution Approach 2:
The invention merges the functions of lift generation, stability, and control into a single integrated rotative wing surface system. By combining these functions that are typically performed by separate components (wings, stabilizers, and control surfaces) into one unified structure, the aircraft complexity is reduced while achieving all required functions.
3Speed
If rotors or blades are used for propulsion and lift, then vertical flight is enabled, but aerodynamic resistance increases at high speeds
Solution Approach 1:
The rotative wing surface is designed to dynamically adjust its rotational characteristics: it rotates rapidly for vertical take-off and landing operations, then transitions to a different rotational mode for horizontal flight. This dynamic adaptation allows the aircraft to optimize its performance for each flight phase, achieving vertical capability when needed while minimizing aerodynamic drag during high-speed horizontal flight.
Solution Approach 2:
The invention changes the operational parameters of the rotative wing surface between different flight modes: rotation speed, axis orientation, and rotational plane are adjusted according to whether the aircraft is in vertical or horizontal flight. This parameter transformation enables the same structure to perform both vertical take-off functions and high-speed horizontal flight with reduced drag.
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 design achieves high stability, maneuverability, and efficiency by leveraging gyroscopic properties for orientation and control, reducing aerodynamic resistance, and enabling vertical take-off and landing, with the ability to fly at supersonic speeds and operate in various configurations.
Implementation Method 1
It is known in the state of the art that every rotating object has gyroscopic properties and tends to maintain a certain trajectory, opposing with resistance to a modification of it.
Implementation Method 2
propulsion is obtained by blades or by any motorized means providing a higher propulsion than the weight of the aircraft. Rotating blades used for example in helicopters made the air to be driven in order to overcome the forces opposed to the forward displacement of the aircraft and to its elevation.
