AI Technical Summary

Technical Problem

Existing aircraft immobilization systems, such as Engineered Material Arresting Systems (EMAS), cause significant damage to aircraft and disrupt airport logistics due to mechanical stress and the need for extensive repairs, while other systems are unsuitable for integration into airport runways.

Method used

An aircraft immobilization system comprising a frame with a receiving mat and conveyor belts that absorb an aircraft's kinetic energy by matching its speed and then braking upon landing gear contact, minimizing mechanical stress and allowing immediate immobilization without damaging the aircraft.

Benefits of technology

The system effectively immobilizes aircraft without causing damage, reduces repair costs, minimizes logistical disruptions, and allows for quick resumption of air traffic, maintaining the aircraft's mechanical integrity and safety.

Abstract

The invention relates to a system, housed in a pit in an aircraft runway, comprising at least one immobilizing member (1) which comprises a framework (2) that is fixed relative to the walls of the pit, a receiving mat (3) intended to receive landing gear of the aircraft, drive means (4) for driving this mat relative to the framework, braking means (5) for braking this mat, and control means (8) able to activate the drive means in response to a first signal, then deactivate the drive means while activating the braking means in response to a second signal. The system according to the invention provides for the immobilization of an aircraft in difficulty without significant stresses being exerted on this aircraft, which remains in perfect flying condition. The invention makes it possible to do away with any subsequent operation for checking the integrity of the aircraft structure. Moreover, the invention makes it possible to avoid any technical unavailability of the runway. Lastly, the invention is applicable to the immobilization of aircraft during both the landing phase and the take-off phase thereof.
