Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft sensing systems require large volumes, compromise signal quality due to refraction and reflection through transparent parts, and are cumbersome to reconfigure.
Innovation Solution
Aircraft with a moving system that includes a frame, slide, and guides to move sensing means between rest and work positions, using drive means, dampers, and abutment elements to ensure direct sensing outside the aircraft without passing through transparent parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical arm is used to allow the sensor to exit the aircraft through a port, then the sensor can be positioned outside the aircraft, but the use of space on the aircraft increases and vibrational performance deteriorates
Solution Approach 1:
The moving system is divided into modular components: a frame structure, a slide mechanism, and telescopic draw parts. This segmentation allows each component to be optimized independently while maintaining overall system functionality, reducing installation complexity while preserving sensing signal quality.
Solution Approach 2:
The system employs a dynamic moving mechanism that allows the sensing means to transition between retracted and extended positions. The slide and telescopic draw parts enable smooth, controlled movement, reducing vibrations during operation while maintaining the ability to position sensors outside the aircraft for optimal signal quality.
2Reliability
If a large volume is used to move the sensors, then the sensing means can be properly positioned, but the footprint inside the aircraft increases
Solution Approach 1:
The telescopic draw parts are nested within each other, allowing the moving system to achieve a long stroke for sensor positioning while maintaining a compact retracted profile. When not in use, the draw parts retract into the frame, minimizing the footprint inside the aircraft while preserving the ability to extend sensors to optimal positions for stable sensing operations.
Solution Approach 2:
The system utilizes the depth dimension of the aircraft interior by extending sensors through the fuselage thickness. The slide moves sensors along the sensing direction (perpendicular to aircraft skin), allowing long sensor extensions without increasing lateral footprint, thereby maintaining stable sensing operations while preserving interior space.
3Ease of operation
If the sensing signal passes through a transparent part such as a window, then the sensor can be positioned inside the aircraft, but the signal quality deteriorates due to refraction and reflection
Solution Approach 1:
The moving system extracts the sensing means from the protected interior environment and positions them directly outside the aircraft through controlled movement. By taking the sensors outside the aircraft structure, the system eliminates the need for signals to pass through transparent parts, thereby preserving measurement precision while maintaining ease of operation through automated positioning mechanisms.

AI summary
An aircraft is provided that has a moving system for moving, during flight, sensors of the aircraft between a rest position in which the sensors are arranged within the aircraft, and a work position in which the sensors face directly, along a sensing direction, towards outside of the aircraft and towards the ground when the aircraft is in flight. The moving system has a frame arranged inside the aircraft, a slide supporting the sensors, and a pair of guides, each guide having a rail part supported on the frame, and at least one draw part arranged telescopically slidable relative to the relevant rail part along a direction of movement perpendicular to the sensing direction. The slide, mounted integrally with the draw parts of the pair of guides, slides along the direction of movement internally within the aircraft to move the sensors between the rest and work positions.
