Flight Assistance Yoke with Tactile Feedback for Stall Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight assistance systems fail to effectively inform pilots of critical flight ranges, such as stall states, leading to inadequate measures being taken when an aircraft approaches these conditions.
Innovation Solution
A flight assistance apparatus equipped with a yoke and a flight instruction section that uses motors, potentiometers, and flight sensors to instruct pilots to avoid critical flight ranges by physically manipulating the yoke grip portions, providing tactile feedback and directional guidance to prevent aircraft from entering hazardous conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a flight grip member is made to vibrate to inform the pilot of an approach to a stall state, then the pilot is alerted to the critical condition, but the pilot is not enabled to take appropriate measures
Solution Approach 1:
The system provides continuous feedback to the pilot through the flight instruction section that generates tactile sensations on the grip member. The feedback changes dynamically based on the aircraft's flight state, guiding the pilot's corrective actions in real-time until the aircraft exits the critical flight range.
Solution Approach 2:
The flight instruction section acts as an intermediary between the flight state monitoring system and the pilot. It translates critical flight data into intuitive tactile instructions through the grip member, enabling the pilot to understand and respond appropriately without being overwhelmed by raw data.
2Device complexity
If simple vibration is used to alert the pilot, then the system remains simple, but the pilot cannot take appropriate corrective actions
Solution Approach 1:
The tactile sensation on the grip member is not static but dynamically adjusted based on the aircraft's real-time flight state. The intensity, frequency, and pattern of the tactile feedback change as the aircraft approaches and recovers from critical conditions, providing the pilot with evolving guidance instructions.
Solution Approach 2:
The system changes multiple parameters of the tactile feedback including vibration frequency, amplitude, and duration based on the degree and type of critical flight condition. These parameter changes encode specific instructional information to guide the pilot's corrective actions appropriately.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables pilots to appropriately operate the aircraft and avoid critical flight ranges, ensuring smooth navigation and preventing collisions or stalls by providing clear, intuitive instructions through the yoke's mechanical feedback.
Implementation Method 1
an actuator 54 fixed to a leg portion of the seat 52 to move the seat 52 along the rail guide 53
Implementation Method 2
A flight sensor 8 that detects an operation direction of the yoke 2 and an angle of the yoke 2 is connected to the controller 7
Implementation Method 3
The controller 7 controls the actuator 18 or 23 to instruct the pilot to operate the yoke 11 in such a direction as to avoid a collision range
