Flying Apparatus Cooling Layout for Tilt-Stable Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying apparatuses face challenges in smoothly circulating coolant for driver cooling when the apparatus tilts during flight, as the pump is mounted on the upper portion of the main body assembly, obstructing smooth coolant circulation.
Innovation Solution
The cooling system is designed with a pump located at the lower portion of the main body assembly, connected via pipes to the driver and cooler, with radiators positioned horizontally and overlapping a fuel tank, ensuring continuous coolant circulation even during tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pump is mounted on the upper portion of the main body assembly, then the structure is simplified, but coolant circulation becomes insufficient when the apparatus tilts during flight
Solution Approach 1:
The pump is inverted from its conventional upper mounting position to the lower portion of the main body assembly. This inversion allows the pump to maintain proper orientation for coolant circulation even when the flying apparatus tilts during flight, resolving the contradiction between structural simplicity and cooling reliability.
2Ease of manufacture
If the pump is mounted on the upper portion of the main body assembly, then installation is easier, but coolant circulation is obstructed during tilting flight
Solution Approach 1:
The pump mounting position is inverted from upper to lower portion of the main body assembly. This design maintains ease of installation while ensuring that the pump remains in an optimal position for coolant circulation during tilted flight operations.
3Device complexity
If the cooler is positioned above the driver, then the cooling system layout is simplified, but coolant circulation becomes insufficient during tilting flight
Solution Approach 1:
The relative positions of the cooler and driver are inverted from the conventional arrangement. The cooler is positioned below the driver, which maintains a simple cooling system layout while ensuring adequate coolant circulation during tilted flight by allowing gravity to assist coolant flow back to the pump.
