Solution Overview

Problem

Dynamic ground conditions during airdrops, such as changing weather and enemy/disaster location, pose challenges to achieving precision and accuracy in drop zone targeting, as existing systems rely on operator updates and real-time data transfer for adjusting airdrop parameters.

Innovation Solution

A method and system that continuously monitor and transmit ground-based parameters to an in-flight cargo aircraft's flight management system, allowing for automatic adjustments to the computed air release point and flight performance parameters, ensuring accurate and precise airdrop by establishing initial drop zone dimensions and updating them in real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If real-time monitoring and automatic adjustment of airdrop parameters is implemented, then airdrop accuracy and precision are improved, but system complexity and cost increase

Engineering Contradiction:
Improveairdrop accuracyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The FMS is designed to perform multiple functions: it serves as both the flight management system for normal aircraft operations and the airdrop parameter adjustment system. The system can process various types of input data (ground conditions, weather, aircraft performance) and generate different types of output (release point adjustments, flight parameter modifications) through a unified computational framework, reducing the need for separate dedicated systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically monitors ground-based parameters, receives updates via data link, and adjusts airdrop parameters without requiring continuous manual intervention from operators. The FMS self-updates the computed air release point and flight performance parameters based on real-time data, enabling the system to serve itself in maintaining airdrop accuracy.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If continuous monitoring and real-time updates of ground parameters are performed, then airdrop precision is improved, but loss of time and operational burden increase

Engineering Contradiction:
Improveairdrop precisionVSAvoidtime for parameter adjustment
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements continuous monitoring of ground-based parameters and maintains an ongoing data link between the ground element and the aircraft's FMS. Instead of periodic updates, the system continuously receives and processes parameter changes, ensuring that the airdrop parameters are always current without requiring intermittent manual intervention or time-consuming update cycles.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system establishes a feedback loop where ground-based parameter changes are automatically detected, transmitted to the aircraft, and used to adjust airdrop parameters in real-time. The FMS continuously compares current ground conditions with the planned airdrop parameters and makes necessary adjustments, creating a closed-loop control system that automatically corrects deviations without manual intervention.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If automatic adjustment of computed air release point is implemented, then adaptability to changing ground conditions is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The FMS is designed to handle multiple types of ground-based parameters (coordinates, weather conditions, ground speed, wind) and various airdrop scenarios through a unified computational algorithm. The same system core processes different parameter types and generates appropriate adjustments for various airdrop configurations, reducing the need for separate specialized systems for each parameter type or scenario.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Methods and systems are provided for automatically adjusting aircraft performance parameters for use on an airdrop. The method comprises establishing and transmitting initial dimensions for a drop zone from a ground element to a flight management system (FMS) of an in-flight cargo aircraft via a secure data link. The ground element continually monitors ground-based parameters affecting the dimensions of the drop zone and transmits changes to the parameters to the FMS via the secure data link. The FMS adjusts a computed air release point (CARP) for the airdrop and continually updates flight performance parameters for the in-flight cargo aircraft based on the changes to the ground-based parameters.
