METHOD OF DETERMINING A TRAJECTORY FOR A ROTORCRAFT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240021089 titled 'METHOD OF DETERMINING A TRAJECTORY FOR A ROTORCRAFT
Simplified Explanation
The patent application describes a method for determining a trajectory for a rotorcraft, such as a helicopter or drone. The method involves the following steps:
- Receiving an initial trajectory that defines the planned flight path of the rotorcraft between a starting point and a target point.
- Performing iterations of a loop that includes adding the initial trajectory to a set of selectable trajectories.
- Evaluating a noise indicator of the rotorcraft for the initial trajectory based on a noise-related acoustic footprint and a noise exposure level-related acoustic footprint.
- Adding the evaluated noise indicator to a set of evaluated noise indicators.
- Determining an alternative trajectory that defines an alternative flight path of the rotorcraft between the starting point and the target point based on the evaluated noise indicator.
- Setting the alternative trajectory as the initial trajectory.
- Outputting a trajectory from the set of selectable trajectories that is associated with a selected noise indicator fulfilling predetermined noise indicator conditions.
Potential applications of this technology:
- This method can be used in the aviation industry to optimize flight paths for rotorcraft, minimizing noise pollution in populated areas.
- It can be applied to urban air mobility systems, allowing for efficient and low-noise transportation in urban environments.
- The method can be used by drone operators to plan flight paths that minimize noise disturbance to sensitive areas, such as wildlife habitats or residential neighborhoods.
Problems solved by this technology:
- Noise pollution caused by rotorcraft can be a significant concern, especially in urban areas. This method helps address this problem by providing a way to determine flight paths that minimize noise impact.
- By evaluating noise indicators and selecting trajectories based on predetermined noise indicator conditions, this method ensures compliance with noise regulations and guidelines.
Benefits of this technology:
- The method allows for the optimization of flight paths, reducing noise pollution and improving the overall environmental impact of rotorcraft operations.
- By minimizing noise disturbance, this technology can help improve the quality of life for people living in areas affected by rotorcraft noise.
- It provides a systematic approach to selecting flight paths, taking into account noise-related factors, which can lead to more efficient and effective rotorcraft operations.
