Lofted Flight Guidance for Adapting to Target Course Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for extending the flight distance of a flying object fail to adapt optimally when the target changes its course, leading to suboptimal flight paths and reduced fuel efficiency due to rapid turns and increased fuel consumption.
Innovation Solution
A guiding device equipped with a communication device and processing unit that receives detection signals from the target, determines a progressing direction for the flying object, and adjusts its flight course in real-time based on detection data, using a combination of lofted flight courses calculated through simulations to maintain optimal trajectory and extend flight distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a flight course is determined once at launch to extend flight distance, then the flight distance is extended, but the course becomes suboptimal when the target changes its moving course
Solution Approach 1:
The patent applies dynamics by transitioning from a static, pre-determined flight course to a dynamic, real-time adjustable flight course. The guiding device continuously receives detection signals about the target's position and updates the flight course during the flying object's flight, allowing the course to adapt dynamically to target movements while maintaining extended flight distance through lofted flight techniques.
2Duration of action of moving object
If the flying object launches at a higher launching angle to extend flight distance, then the flight distance is extended, but the interception probability decreases when the target moves rapidly
Solution Approach 1:
The patent implements feedback by continuously receiving detection signals containing target position information during flight and using this feedback to update the flight course in real-time. This closed-loop control allows the system to maintain high interception probability by adjusting the flight path based on current target position while preserving the benefits of lofted flight for extended distance.
3Reliability
If the flying object performs rapid turns to track a moving target, then the interception probability increases, but the fuel consumption increases and flight distance decreases
Solution Approach 1:
The patent applies preliminary action by calculating and setting an optimal lofted flight course in advance that accounts for the target's movement. Instead of making reactive rapid turns during flight, the system pre-plans a course that anticipates target movement based on detection data, allowing the flying object to maintain a more fuel-efficient trajectory while still achieving high interception probability.

AI summary
In a guiding device, a communication device receives a signal containing detection data of a target, and a processing unit. In the processing unit, a course setting section sets a flight course for a lofted flight based on the detection data, and a guiding section determines a progressing direction based on the flight course and outputs a guidance signal containing the progressing direction. The course setting section sets a first flight course when the flying object is launched. Also, the course setting section changes the first flight course to a second flight course based on the detection data after launching of the flying object.
