Drone Propulsion Pivoting for Stable Flight Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft, particularly drones, face challenges in achieving stable flight stabilization due to the lack of independent pivoting mechanisms for propulsion arrangements, leading to imbalances and instability.
Innovation Solution
The aircraft is equipped with independently pivotable propulsion arrangements and a pivotable trunk body, each with dedicated actuating drives, allowing for precise control and stabilization through a first axis of pivoting for the propulsion arrangements and a second axis for the trunk body, enhancing balancing and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If propulsion arrangements are mounted pivotably about a first axis at an angle to the direction of propulsion, then flight stabilization is improved, but device complexity increases
Solution Approach 1:
The propulsion arrangements are mounted pivotably about a first axis at an angle to the direction of propulsion, allowing dynamic adjustment of the propulsive thrust direction. This dynamic capability enables the aircraft to actively stabilize its flight by pivoting the propulsion arrangements to counteract disturbances, while the pivotable mounting itself provides the necessary adaptability without requiring overly complex stabilization systems.
2Stability of the object's composition
If propulsion arrangements are pivoted independently of one another, then flight stabilization is improved, but control complexity increases
Solution Approach 1:
The aircraft is equipped with multiple propulsion arrangements (at least two) that are arranged at a distance from one another on the supporting body. Each propulsion arrangement can be pivoted independently about the first axis, allowing segmented control of different propulsion units. This segmentation enables independent adjustment of each propulsion arrangement to achieve optimal flight stabilization while distributing the control complexity across multiple independently controllable units.
3Reliability
If redundant motor drives with gearboxes and brakes are provided, then reliability is improved, but device complexity increases
Solution Approach 1:
The aircraft is provided with redundant motor drives, each comprising at least two motors with gearboxes and a brake that can block the gearbox. This redundancy is built in beforehand to cushion against potential failures of individual motors or components. The brake mechanism provides a safety backup to prevent uncontrolled movement if the motors fail, ensuring reliable and safe operation while the redundant components are integrated into the overall drive system design.

AI summary
Described is an aircraft, in particular a drone, with a supporting body (2) and at least two propulsion arrangements (4, 8) arranged at a distance from one another on the supporting body (2), which are designed to generate a propulsive thrust in a direction of propulsion (8b). According to a first aspect of the invention, the propulsion arrangements (4, 8) on the supporting body (2) are each mounted so as to be pivotable independently of one another about a first axis of pivoting (6) extending at an angle to the direction of propulsion (8b) and a first actuating drive (10) is provided and designed to pivot the propulsion arrangements (4, 8) independently of one another about the first axis of pivoting (6). According to a second aspect of the invention, in which a trunk body (20) is provided, this trunk body (20) is mounted on the supporting body (2) so as to be pivotable about a second axis of pivoting (22) and a second actuating drive (24) is provided and designed to pivot the supporting body (2) relative to the trunk body (20).
