Backward-Tilting Delivery Payload Mechanism for Cruise Drag Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying objects face challenges in increasing cruising range and fuel efficiency, particularly when transporting larger and heavier loads, and face difficulties in areas where external power supply is unavailable.
Innovation Solution
A flying object design with a loading part that is tilted backward in the forward and backward direction during landing or hovering, optimizing the position of the payload to reduce drag and improve fuel efficiency by minimizing the difference in motor speeds and reducing the frontal projected area during cruising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the loading part or delivery is attached horizontally in the landing or hovering state, then the cargo can be easily loaded and unloaded, but the fuel efficiency decreases during cruising due to increased drag and motor speed variations
Solution Approach 1:
The loading part is designed to be tiltable relative to the airframe, allowing it to change orientation between landing/hovering and cruising states. During landing or hovering, the loading part is tilted backward so that its upper surface is substantially horizontal, facilitating easy loading and unloading of cargo. During cruising, the loading part is tilted forward to reduce drag and minimize motor speed variations, thereby improving fuel efficiency. This dynamic adjustment resolves the contradiction between ease of operation and energy efficiency.
2Quantity of substance
If larger and heavier goods are carried to increase delivery capacity, then the delivery capability improves, but drag and motor addition increase leading to decreased fuel consumption
Solution Approach 1:
The tiltable loading part allows the flying object to optimize its aerodynamic configuration when carrying larger and heavier goods. By tilting the loading part forward during cruising, the design minimizes the frontal projected area and reduces drag, thereby improving fuel consumption even when transporting larger payloads.
3Use of energy by moving object
If the loading part is tilted backward during landing or hovering, then the fuel efficiency improves during cruising, but the loading and unloading operation becomes more difficult
Solution Approach 1:
The loading part is designed with tilting capability that allows it to be positioned at different angles according to the flight state. During landing or hovering, the loading part is tilted backward so that its upper surface is substantially horizontal, making it easy to load and unload cargo. During cruising, the loading part is tilted forward to improve fuel efficiency by reducing drag. This dynamic reconfiguration resolves the contradiction between ease of operation and fuel efficiency.
