Solution Overview
Problem
Conventional rotary-wing drones face limitations in performing high-speed descending attacks and accurately estimating target locations for self-destruct missions, as they struggle to effectively use GPS systems and laser range finders for precise targeting and vertical descent.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional rotary-wing drones are used for self-destruct attacks, then they can perform attacks, but they cannot fly down at high speeds to attack the upper part of the enemy
Solution Approach 1:
The patent inverts the conventional rotary-wing design by enabling bidirectional rotation of the propellers. By rotating propellers in reverse direction during descent, the drone can achieve high-speed vertical attacks while maintaining attack capability, effectively solving the speed limitation of conventional single-direction rotary-wing drones
2Measurement precision
If conventional targeting equipment is used, then target search can be performed, but accurate global coordinate acquisition and location estimation are limited
Solution Approach 1:
The patent merges multiple targeting functions into a single integrated system. The TADS combines laser range finder, GPS module with two antennas for moving baseline positioning, and image processing capabilities into one unified targeting system that automatically calculates 3D coordinates, eliminating the need for separate targeting devices and reducing overall system complexity while improving accuracy
Solution Approach 2:
The GPS module with two antennas serves multiple functions: it provides both positioning information and enables moving baseline positioning for accurate azimuth and elevation angle measurement. The laser range finder simultaneously measures distance and works with the GPS data to calculate complete 3D target coordinates, demonstrating multi-functionality that improves precision without proportionally increasing complexity
