Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pilot training methods for rotorcraft engine failures do not effectively simulate asymmetric flight phases, leading to engine stress and potential damage, and lack a means to assess pilot progress during such simulations.
Innovation Solution
A method and system for rotorcraft flight training that simulates asymmetric flight phases by controlling engine power distribution and display, allowing pilots to experience transitions between AEO, asymmetric, and OEI modes, with simulated power displays to enhance training realism and reduce engine stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots are trained using actual engine failure simulations with real asymmetric flight phases, then training realism and pilot skill assessment are improved, but engine stress increases and potential damage occurs
Solution Approach 1:
The patent creates a virtual copy of the asymmetric flight phase experience through a simulation system. The training system reproduces the sensory and operational aspects of engine failure without actual engine shutdown, allowing pilots to practice asymmetric flight procedures on a safe virtual replica of the failure scenario.
Solution Approach 2:
The simulation system acts as an intermediary between the pilot and the actual engine system. It mediates the training process by providing virtual feedback and scenarios that mimic real engine failure conditions without directly stressing the physical engines, thus protecting them while maintaining training value.
2Adaptability or versatility
If engines are operated in OEI mode during simulation training, then asymmetric flight training is achieved, but engine maintenance costs increase due to high stress on the operating engine
Solution Approach 1:
The system creates a virtual replica of the OEI training scenario where pilots experience asymmetric flight conditions without actual engine shutdown. This virtual copy provides the same training value regarding asymmetric flight control and engine management without subjecting the physical engine to the high stress of real OEI operation.
Solution Approach 2:
The patent replaces the mechanical stress of actual engine failure and OEI operation with a virtual simulation system. The physical mechanical system (engines operating in high-stress OEI mode) is substituted with an informational/computational system that models the same scenarios without physical wear and tear.
3Object-affected harmful factors
If all engines are operated simultaneously during simulated engine failure, then engine stress is reduced, but the ability to assess pilot skills in actual asymmetric flight conditions is diminished
Solution Approach 1:
The simulation system creates a virtual copy of the asymmetric flight phase that accurately replicates the pilot workload, control inputs, and decision-making requirements of real engine failure. This virtual scenario provides precise measurement of pilot skills in asymmetric flight conditions without the compromise of running all engines simultaneously.
Solution Approach 2:
The system implements feedback mechanisms that provide the instructor with detailed information about pilot performance during the simulated asymmetric flight phase. This feedback includes control inputs, response times, and procedural adherence, enabling accurate skill assessment without requiring actual engine failure conditions.
4Strength
If simulated asymmetric flight phases are not implemented, then engine integrity is maintained, but pilot training in asymmetric flight scenarios becomes ineffective
Solution Approach 1:
The patent creates a virtual copy of the asymmetric flight training experience that preserves engine integrity while maintaining training effectiveness. The simulation reproduces all critical aspects of engine failure and asymmetric flight operations, allowing pilots to practice procedures and receive assessment without compromising physical engine strength.
Solution Approach 2:
The simulation system serves as an intermediary that decouples the training objective from the harmful physical effects. It mediates between the need for realistic asymmetric flight training and the need to preserve engine integrity, providing a safe intermediate environment for skill development.
