Solution Overview
Problem
The integration of weapon systems with aircraft is complex and time-consuming, requiring extensive storage and computational resources due to the need for distinct models for each weapon type, leading to increased costs and lengthy integration processes.
Innovation Solution
A computer-implemented method using a generic algorithm to generate coefficients for a polynomial model that describes the performance envelope of a weapon, allowing for the creation of a feasibility display indicating the likelihood of successful engagement, which can be applied to various weapon types and aircraft without the need for extensive re-certification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distinct models are created for each weapon type, then the accuracy of weapon performance prediction is improved, but the device complexity and storage requirements increase
Solution Approach 1:
The patent implements a universal polynomial model framework that can represent multiple weapon types using a single mathematical structure. The generic polynomial form with adjustable coefficients allows the same model to accurately predict performance across different weapon types (air-to-air, air-to-ground, etc.), eliminating the need for separate bespoke models for each weapon while maintaining prediction accuracy.
Solution Approach 2:
The patent changes the approach from creating structurally different models for each weapon to using the same model structure with different parameter values. By adjusting the polynomial coefficients to match specific weapon characteristics, the system achieves weapon-specific accuracy without increasing model structural complexity or storage requirements.
2Reliability
If bespoke models are created for each weapon type, then the weapon-specific performance characteristics are captured accurately, but the integration time and cost increase
Solution Approach 1:
The patent performs preliminary work by establishing a universal polynomial model framework in advance that can accommodate any weapon type. This pre-established framework eliminates the need for time-consuming bespoke model creation during weapon integration, as the model structure is already validated and ready to be configured with weapon-specific coefficients.
Solution Approach 2:
The universal polynomial model serves multiple weapon types simultaneously, allowing the same software platform to handle air-to-air, air-to-ground, and other weapon categories without requiring separate integration processes. This multi-functionality dramatically reduces integration time and cost while maintaining weapon-specific performance accuracy through coefficient adjustment.
3Reliability
If comprehensive integration is performed for each weapon model, then the reliability of aircraft system compatibility is improved, but the productivity and affordability decrease
Solution Approach 1:
The patent merges the integration process for multiple weapon types into a single unified process. By combining various weapon-specific considerations into one generic polynomial model framework, the system achieves comprehensive aircraft system compatibility validation once, rather than requiring separate comprehensive integration for each weapon type, thereby improving productivity and affordability.
4Measurement precision
If separate models are used for different weapon types, then the weapon performance specificity is improved, but the storage capacity requirements increase
Solution Approach 1:
The patent uses a copying approach where a single universal model template is replicated and configured for different weapon types by adjusting coefficients rather than storing entirely separate models. This significantly reduces storage requirements while maintaining weapon performance specificity, as only the coefficient data needs to be stored for each weapon type rather than complete model definitions.

AI summary
A feasibility display indicative of a feasibility of a weapon successfully engaging a target and/or a feasibility of a weapon successfully engaging the aircraft is generated. The aircraft in conjunction with another device cooperatively generate the same. The another device has a database describing a performance envelope of the weapon. The another device identifies a best candidate polynomial from a plurality based on scores of the plurality. Each score is based on a quality of fit of the candidate polynomial to a characteristic of the performance envelope of the weapon. The another device uploads, after a plurality of characteristics are evaluated, to the aircraft coefficients which are determined for the best candidate polynomial Variables of the plurality are some or all of a weapon or aircraft firing condition parameters The aircraft uses selected coefficients to generate the feasibility display where selection is based on conditions of the aircraft and target.
