20130087654 | APPARATUS FOR RECOVERING KINETIC ENERGY RELEASED DURING LANDING OF AN AIRCRAFT AFTER CONTACT WITH THE GROUND, AND METHOD - At least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy from a landing aircraft. The system has a high degree of multiple utilisation and enables, for example, manoeuvring of a landed aircraft on the taxiway independently of the engines, where the aircraft is substantially moved with the braking energy recovered during the landing process. As a result of the main engines no longer being required for manoeuvring, there is a considerable potential for saving energy and the use of motor-operated tow vehicles is eliminated. The apparatus also contributes in the sense of a “green” and economical technology to saving aircraft fuel and better fulfils future requirements of airports, particularly with a view to noise and pollutant reduction. In addition, the invention has as its subject matter a method for recovering braking energy of an aircraft. | 04-11-2013 |
