Sliding Radome Axial Track and Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft radome designs face challenges such as ground contact during rotation, additional blockage due to structural beams, and the need for external support equipment, which can impair radar system functionality and accessibility.
Innovation Solution
A radome design featuring a shell with an axial track system that moves between open and closed positions, coupled with a support structure that expands to maintain clearance and stability, allowing axial movement and secure access to the radar system without compromising radio wave transmission or reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single radome structure is hinged on one side and rotates to open, then access to the radar system is provided, but the radome may contact the ground during rotation when clearance is insufficient
Solution Approach 1:
The radome transitions from a static hinged structure to a dynamic telescoping structure that can extend and retract along the aircraft body, allowing controlled movement without ground contact while maintaining accessibility
2Strength
If a two-piece clam shell structure with a central beam is used, then structural support is provided, but the beam moves the radar system closer to the aircraft body causing additional blockage
Solution Approach 1:
The radome is divided into multiple telescoping sections that can extend independently, distributing structural support across multiple segments rather than requiring a single central beam that would block radar signals
3Strength
If a single radome structure is coupled with multiple coupling devices, then structural attachment is provided, but external ground support equipment is required during removal
Solution Approach 1:
The telescoping radome structure incorporates self-supporting capabilities through its extended configuration, allowing it to stabilize itself during maintenance access without requiring external ground support equipment

AI summary
A radome includes a shell defining an internal volume. A track is coupled to the shell, and the track allows the shell to move axially between an open position and a closed position. A support structure is coupled to the shell, and the support structure moves from a collapsed position to an expanded position.
