Innovation Solution
An autonomous unmanned aerial vehicle equipped with a balloon inflated behind it, using a combination of internal combustion and electrical engines, allowing vertical take-off and landing, silent long-duration flight, and eliminating the need for a landing track, with a hydrogen fuel system for eco-friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fixed-wing unmanned aerial vehicles are used, then flight speed and range are improved, but flight duration is limited and a landing track is required
Solution Approach 1:
The aerial vehicle is divided into two main functional segments: a fixed-wing aircraft portion for high-speed flight and a balloon portion for stationary hovering. This segmentation allows each component to perform its optimal function - the fixed wings provide speed and range while the balloon provides extended duration by enabling stationary airtime without requiring continuous forward motion or a landing track
Solution Approach 2:
The invention merges a fixed-wing aircraft with a balloon system into a single integrated aerial vehicle. The balloon is attached to the fixed-wing aircraft, combining the high-speed capabilities of fixed-wing flight with the stationary hovering capability of balloons, thereby eliminating the need for a landing track while extending flight duration
2Length of moving object
If fixed-wing unmanned aerial vehicles are used, then flight range is improved, but stability and operational flexibility deteriorate due to requiring a landing track
Solution Approach 1:
By segmenting the vehicle into fixed-wing and balloon portions, the system can operate in two distinct modes: high-speed transit mode using the fixed wings for extended range, and stationary mission mode using the balloon for stable positioning without requiring a landing track, thereby improving operational flexibility
Solution Approach 2:
The merged fixed-wing and balloon system provides adaptability by allowing the vehicle to transition between different operational states - using the fixed wings for long-range travel and the balloon for stable stationary operations, eliminating the constraint of requiring a landing track for takeoff and landing
3Power
If conventional engines are used, then thrust and power are improved, but noise level increases reducing stealth capability
Solution Approach 1:
The balloon acts as an intermediary element that enables the vehicle to transition from powered flight to passive stationary hovering. Once the balloon is inflated, the engine can be reduced or shut off, and the vehicle maintains its position using buoyant forces, thereby eliminating engine noise while preserving the ability to generate thrust when needed
