Aircraft Intercept Lines for Airborne Target Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for intercepting airborne targets, such as unmanned rotorcraft, often leave disabled targets difficult to control due to interference with rotors and additional mass, posing a continued threat due to uncontrolled landing.
Innovation Solution
An aircraft equipped with two types of lines - thinner lines for tangling with rotors and thicker, adhesive-expressing lines for bonding to non-moving parts, allowing for reliable attachment and control of the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a net is fired towards the target to intercept it, then the target rotorcraft becomes disabled by interference with rotors, but the disabled target remains difficult to control for safe landing
Solution Approach 1:
The intercepting system is divided into two distinct line types: thinner lines for rotor tangling and thicker adhesive lines for body attachment. This segmentation allows each line type to perform its specific function optimally, with the adhesive lines providing control capability that the net alone cannot achieve.
Solution Approach 2:
The invention uses composite line structures combining different materials and properties - thin flexible lines for rotor interaction and thick adhesive lines for body attachment. This composite approach integrates the advantages of both line types to achieve both disablement and control functions simultaneously.
2Reliability
If thicker adhesive lines are used to attach to non-moving parts, then reliable bonding is achieved, but the device complexity increases
Solution Approach 1:
The frame structure serves multiple functions: it provides attachment points for both thin and thick lines, maintains proper spatial arrangement, and enables the aircraft to perform both rotor tangling and body attachment operations. This multi-functionality reduces the need for separate specialized structures.
Solution Approach 2:
Different regions of the frame are equipped with different line types based on local requirements - thinner lines attached to the inner member for rotor interaction and thicker lines attached to the outer member for body attachment. This local differentiation optimizes performance while managing complexity.
3Adaptability or versatility
If multiple types of lines are provided on the aircraft, then more attachment possibilities are available, but the manufacturing complexity increases
Solution Approach 1:
Both thin and thick lines are pre-attached to the frame during manufacturing, with their attachment points and spatial arrangements predetermined. This preliminary configuration simplifies assembly operations during actual intercept missions while maintaining manufacturing efficiency through standardized frame designs.
