Detachable Aircraft Wing Mount for Emergency Landing Impact Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft with wings located on the top of the fuselage face challenges in emergency landings due to increased weight from installed parachutes and difficulty in deploying them, which can cause severe deformation or damage to the fuselage, threatening passenger safety.
Innovation Solution
The aircraft is equipped with detachable wings connected via a severable fixing portion, such as explosive bolts, which are severed upon detection of a strong impact during an emergency landing, allowing the wings to rotate and contact the ground, thereby reducing the load on the fuselage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wings are located on the top of the fuselage, then passenger convenience for boarding and alighting is improved, but fuselage deformation and damage during emergency landing increases
Solution Approach 1:
The wing connection system is segmented into a fixed connection portion and a detachable connection portion. The detachable portion includes fixing portions that can be severed to separate the wing from the fuselage, allowing the wing to be divided into separable segments rather than a single rigid structure.
Solution Approach 2:
The connection between the wing and fuselage transitions from a static fixed state to a dynamic detachable state. The fixing portions are designed to remain connected during normal operation but can be quickly severed during emergency landing, allowing the system to adapt its structural characteristics based on operational conditions.
2Reliability
If parachutes are installed in the aircraft, then passenger safety during emergency descent is improved, but aircraft weight increases
Solution Approach 1:
The wing is extracted as a separable component from the fuselage structure. During emergency landing, the detachable connection portion is severed to separate the wing from the fuselage, allowing the wing to absorb impact independently while protecting the fuselage and passengers.
Solution Approach 2:
The detachable connection portion is designed to serve as a cushioning mechanism before impact. By allowing the wing to detach and rotate downward, the system prepares for impact absorption in advance, reducing the force transmitted to the fuselage during emergency landing.
3Reliability
If parachutes are installed in the aircraft, then emergency rescue capability is improved, but ease of installation and release becomes difficult
Solution Approach 1:
The manual or complex mechanical release system is replaced with a simpler severing mechanism. The detachable connection portion can be quickly separated using explosive bolts or other rapid-release mechanisms, simplifying the emergency release process compared to traditional parachute installation and deployment systems.
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
This solution minimizes fuselage deformation and enhances passenger safety by absorbing impact through wing detachment, reducing the load on the fuselage during emergency landings.
Implementation Method 1
The fixing portion may include an explosive bolt, and the severing signal may be an ignition signal for igniting the explosive bolt.
