Inflatable Windshield Buttress for Bird Strike Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft windshields are vulnerable to damage from bird strikes and other debris, leading to potential penetration and structural integrity issues, with traditional strengthening methods increasing weight and optical distortion.
Innovation Solution
An in-flight impact protection system that uses a sensor to detect approaching objects and activates an inflation device to buttress the windshield or fuselage, deploying a tube member to exert force against the panel and prevent penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the windshield is made thicker or from stronger material to strengthen protection, then the protection capability against bird strikes is improved, but the aircraft weight increases and optical distortion occurs
Solution Approach 1:
The system performs preliminary detection of approaching objects using sensors (radar, optical, or acoustic) and activates the inflation device before impact occurs. This preliminary action allows the windshield to remain thin and lightweight while still providing protection through the timed deployment of the inflatable cushion that absorbs impact forces.
Solution Approach 2:
The invention uses an inflatable device filled with gas (pneumatic system) to provide impact protection. The inflatable cushion expands rapidly upon detection of an approaching object, creating a protective barrier that absorbs bird strike forces without requiring the windshield itself to be thicker or stronger, thus avoiding weight increase and optical distortion.

This preliminary action allows the windshield to remain thin and lightweight while still providing protection through the timed deployment of the inflatable cushion that absorbs impact forces.

3Strength
If traditional strengthening methods are used to protect against bird strikes, then the protection capability is improved, but the device complexity increases due to thicker fuselage members
Solution Approach 1:
The protection system is segmented into separate functional components: detection sensors, control systems, and inflatable devices. This segmentation allows the windshield and fuselage structure to remain simple and lightweight, while the inflatable protection mechanism provides the necessary impact resistance without complicating the overall fuselage structure.
Solution Approach 2:
The invention uses an inflatable device filled with gas (pneumatic system) to provide impact protection. The inflatable cushion expands rapidly upon detection of an approaching object, creating a protective barrier that absorbs bird strike forces without requiring the windshield itself to be thicker or stronger, thus avoiding weight increase and optical distortion.
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
The system effectively maintains windshield integrity during impacts without increasing aircraft weight or causing optical distortion, ensuring continued safe flight and compliance with safety regulations.
Implementation Method 1
A sensor is also disposed on the aircraft and adapted to transmit a signal and receive a reflection of the signal
Implementation Method 2
An inflation device, which includes a tube member, is coupled to the controller and positioned inside the aircraft, proximate the panel. After determining that the object is near the panel, the controller can activate the inflation device so that the tube member inflates, thereby buttressing at least a portion of the panel

AI summary
An in-flight impact protection system for aircraft. An aircraft having a panel, with a sensor disposed on the aircraft and adapted to transmit a signal and receive a reflection of the signal. A controller coupled to the sensor and adapted to receive the reflection from the sensor to determine whether an object is near the aircraft's panel. An inflation device, which includes a tube member, is coupled to the controller and positioned inside the aircraft, proximate the panel. After determining that the object is near the panel, the controller can activate the inflation device so that the tube member inflates, thereby buttressing at least a portion of the panel. The panel can be a windshield, fuselage member, or other suitable component.
