No-Fly Zone Calculation for Cooperative Air Defense
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face difficulties in determining the appropriate response to a target moving in the air, particularly when both an aircraft and a launch facility deployed on the ground launch a flying object cooperatively, as it is unclear which entity should intercept the target and what course the aircraft should take.
Innovation Solution
A control apparatus that acquires target information and flying object information to calculate a no-fly zone for the aircraft, determining whether the aircraft or the flying object should intercept the target based on their respective times to reach the target, ensuring safe separation and effective response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both an aircraft and a launch facility cooperatively respond to a target, then the response capability is improved, but it becomes difficult to determine which entity should intercept the target and what course the aircraft should take
Solution Approach 1:
The patent introduces a control apparatus as an intermediary that automatically determines interception responsibility and calculates no-fly zones. The control apparatus receives information from both the aircraft and launch facility, processes it according to predetermined rules (comparing times to reach target), and outputs clear guidance to both entities, eliminating the confusion about who should intercept and what path to take.
Solution Approach 2:
The patent uses parameter comparison (time to reach target) as the basis for automatic decision-making. By comparing the time parameter from the aircraft to the target versus the time parameter from the flying object to the target, the system automatically determines which entity should intercept, transforming a complex operational decision into a simple parameter-based rule.
2Speed
If the aircraft flies directly toward the target to respond quickly, then the response time is reduced, but it may conflict with the flying object's course and compromise safety
Solution Approach 1:
The control apparatus performs preliminary calculation of the no-fly zone based on the flying object's trajectory before the aircraft executes its flight path. By pre-determining the restricted area and communicating it to the aircraft, the system ensures the aircraft can respond quickly while automatically avoiding conflict with the flying object's course, thus maintaining both speed and safety.
Solution Approach 2:
The control apparatus creates a virtual representation (copy) of the flying object's trajectory as a no-fly zone, allowing the aircraft to plan its path around this virtual barrier. This copying approach enables the aircraft to maintain high response speed while systematically avoiding the dangerous area without requiring complex real-time coordination.
3Adaptability or versatility
If the pilot manually determines the response strategy, then flexibility in decision-making is maintained, but the complexity of the decision-making process increases the user load
Solution Approach 1:
The control apparatus performs self-service by automatically determining interception responsibility and calculating no-fly zones based on input data from the aircraft and launch facility. The system uses predetermined rules and algorithms to make decisions that would otherwise require complex manual analysis, significantly reducing the pilot's cognitive load while maintaining operational flexibility through programmable response strategies.

AI summary
An object of is to cooperatively appropriately respond to a target moving in the air by an aircraft and a flying object launched from a launch facility. The control facility (16) receives target information including information indicating a position of a target aircraft (18) moving in the air, and SAM information including information indicating a position of an SAM (20) launched from a launch facility (12) toward the target aircraft (18). The control facility (16) then calculates a course of the SAM (20) heading for the target aircraft (18) based on the received target information and SAM information as a no-fly zone of an aircraft (14) that responds to the target aircraft (18).
