Aerodynamic Surface Step Adjustment for Precise Aircraft Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting moveable aerodynamic surfaces on aircraft require extensive labor and resources, leading to increased time and cost in ensuring smooth aerodynamic transitions with stationary surfaces, which is inefficient and costly.
Innovation Solution
The implementation of distributed adjustment mechanisms, including Y-axis and Z-axis adjustment mechanisms with adjustment bolts and receivers, allows for incremental positional adjustments of the landing gear doors relative to the landing gear bay, enabling precise alignment and reducing labor-intensive steps.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional techniques (eccentric mechanisms, shims, adjustable rods) are used to adjust moveable aerodynamic surfaces, then step adjustment between surfaces is achieved, but extensive labor requirements and increased time are needed for assembly and repair
Solution Approach 1:
The adjustment mechanism is divided into discrete modular components including adjustment bolts, receivers with threaded bores, and distributed mounting points. Each receiver can be independently adjusted using standard fastening tools, allowing the aerodynamic surface to be segmented into adjustable sections that can be tuned individually for optimal fit without requiring complex centralized adjustment systems.
2Adaptability or versatility
If conventional adjustment techniques are used, then positional relationship of surfaces can be varied, but the process is labor intensive and costly
Solution Approach 1:
The adjustment mechanism is designed to be self-contained and tool-friendly, where the adjustment bolts and receivers form a complete adjustment system that can be operated independently at each mounting location. The distributed architecture allows technicians to perform adjustments using standard fastening tools without requiring specialized equipment or complex procedures, making the system self-sufficient and easy to manufacture.

AI summary
Adjustment mechanisms (20Y, 20Z), systems and methods allow for a moveable aerodynamic surface (12b) to be positionally adjusted relative to a stationary adjustment surface so as to ensure smooth aerodynamic transition between such surfaces. The adjustment mechanisms (20Y, 20Z) may include a base structure (20) adapted for fixed connection to the moveable aerodynamic surface (12b), a fixed-position receiver (26) opposing the base structure and adapted for positionally fixed connection to the support structure of the moveable aerodynamic surface and an adjustment bolt (24) having a head (24b) and a threaded shaft (24a) extending from the head through an elongate slot of the base structure, the slot defining an elongate axis which is aligned with an adjustment axis for the moveable aerodynamic surface, and being threadably coupled to the receiver to operably interconnect the base structure and the receiver.
