Naval Landing Zone Virtual Projection for Aircraft Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current landing assistance systems for rotary-wing aircraft on naval platforms are difficult and dangerous, especially in rough seas, as they require manual guidance and do not effectively communicate altitude and position information to pilots, leading to potentially hazardous landings.
Innovation Solution
A naval platform with a landing aid system that provides real-time altitude, longitudinal, and transverse position information using display devices controlled by a processing unit, allowing pilots to adjust their aircraft's position and altitude for a safe and smooth landing without the need for manual guidance, using RTK GPS or laser optical systems for precise positioning and color-coded light displays to indicate landing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional landing assistance system with a reduced panel is used, then the system complexity is reduced, but the landing maneuver remains difficult and dangerous for the pilot
Solution Approach 1:
The patent transitions from a 2D reduced panel representation to a 3D full-scale virtual representation on the landing zone. The virtual landing zone is projected at actual scale onto the landing area, providing the pilot with accurate spatial perception in three dimensions, thereby eliminating the disorientation caused by scaled-down representations while maintaining system simplicity.
Solution Approach 2:
The patent creates a virtual copy of the actual landing zone that is projected onto the landing area. This virtual representation replicates the true dimensions and features of the landing zone, allowing the pilot to perceive the actual landing environment accurately. The virtual image serves as a faithful copy that enhances situational awareness without adding physical complexity.
2Device complexity
If manual guidance is used during landing, then the landing assistance system is simpler, but the landing becomes more dangerous and requires operator intervention
Solution Approach 1:
The system enables the pilot to perform self-guided landing by providing all necessary spatial and positional information through the virtual landing zone projection. The pilot can independently adjust the aircraft's position and altitude based on the visual feedback from the virtual representation, eliminating the need for manual operator intervention while enhancing landing safety through accurate real-time information.
Solution Approach 2:
The system provides continuous visual feedback to the pilot through the virtual landing zone projection, showing the aircraft's position relative to the actual landing zone in real-time. This feedback loop allows the pilot to make immediate adjustments to altitude and position, improving landing safety without requiring external operator input or complex manual guidance systems.
3Device complexity
If no altitude information display is provided, then the display system is simpler, but the pilot cannot accurately adjust altitude for smooth landing
Solution Approach 1:
The patent combines multiple information elements (altitude data, longitudinal position, transverse position, and visual landing zone representation) into a single integrated virtual display projected on the landing zone. This unified display system provides comprehensive landing guidance information simultaneously, enabling precise altitude and position adjustment without requiring separate complex display systems for each parameter.
Solution Approach 2:
The system adds a vertical dimension to the display by projecting the virtual landing zone with altitude information at the actual scale on the landing area. This 3D visualization allows the pilot to perceive altitude relationships intuitively, enabling accurate vertical position adjustment for smooth landing while maintaining display system simplicity through the use of projected imagery rather than multiple separate instruments.
