Parachute Drop Trajectory Imaging for Interference Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating the risk of interference between elements dropped from an aircraft, such as paratroopers and trailed deployment bags, rely on qualitative assessments and do not provide a means to quantify the risk or predict its increase with larger stick sizes, leading to potential real-world contacts during jumps.
Innovation Solution
A method and system using cameras on the aircraft to record and analyze the trajectories of deployment bags and elements, calculating the probability of interference by overlapping image data to determine the risk of contact, allowing for a quantitative assessment and safe separation analysis.

Engineering Contradiction Analysis
1Productivity
If the number of paratroopers jumping in a stick is increased, then the productivity of the aircraft is improved, but the risk of interference with deployment bags increases due to their lower vertical position
Solution Approach 1:
The patent performs preliminary identification of deployment bag trajectories and paratrooper jump trajectories before actual jumps. By analyzing recorded images to determine deployment bag positions and movements in advance, the system can predict potential interference zones and adjust operational parameters (such as stick size limits or deployment sequences) before conducting real jumps, thereby preventing interference incidents while maintaining high productivity
Solution Approach 2:
The patent introduces an image analysis system as an intermediary between the aircraft operations and safety assessment. This system records, processes, and analyzes visual data of deployment bag trajectories and paratrooper paths, providing quantitative safety metrics that mediate between the desire to increase stick size for productivity and the need to maintain safe separation to prevent interference
2Ease of operation
If qualitative assessment methods are used to evaluate interference risk, then the ease of operation is improved, but the measurement precision of risk quantification deteriorates
Solution Approach 1:
The patent replaces subjective qualitative assessment methods with an automated image analysis system. The system uses recorded images from cameras to objectively determine deployment bag trajectories, calculate movement areas, and quantify interference risk through systematic image overlap analysis. This substitution eliminates human subjectivity while maintaining operational simplicity through automated processing
Solution Approach 2:
The patent creates visual copies (photograms) of the actual deployment scenario from recorded images. By working with these copied visual representations rather than direct real-time observation, the system can perform detailed trajectory analysis and risk quantification without interfering with actual operations, achieving both measurement precision and ease of operation

AI summary
Method and system of safe separation analysis among elements dropped with a parachute from an aircraft (1) comprising the following steps: • providing at least a camera device located on the aircraft (1), • dropping a plurality of deployment bags (2) and a plurality of elements, • recording by the at least one camera device the images of the trajectories of the deployment bags (2) and of the elements dropped, • displaying in a visual computer program photograms, • identifying over the photograms a movement area (5) for each deployment bag (2) and the trajectories (6) of each dropped element, • overlapping the photograms to determine the number of deployment bag movement areas (2) that is crossed by an element trajectory (6), • calculating in a processing unit the risk of interference (7) for each pair of element trajectory (6) and of deployment bag movement area (2).
