Background & Policy context

Doors from passenger aircrafts are opened and closed manually. Normally, the cabin crew engages in unlocking, opening and closing of the doors. Opening aircraft doors requires a certain physical strength because of the design of contemporary aircrafts and thus constitutes a challenge to some cabin crew members. Particularly in emergency situations this might endanger evacuation and rescue procedures. 


To support cabin crews of commercial passenger airplanes the project aims at developing technical aids to unlock and open aircraft doors in particular under hazardous conditions. More precisely: the project will develop an emergency power supply with a new storage technique consisting of Lithium-Ion (Li-Ion) batteries for aircraft doors and manufacture a respective prototype.


The project pursued the following tasks:

  • Conceptualizing the Li-Ion battery technology;
  • Manufacturing the prototype; 
  • functionality, temperature and vibration tests.

On the basis of the defined architectural concept an autonomous and emergency power supply with a new storage technique (batteries with Li Ion) was designed and a prototype was manufactured. An optimized charge/discharge concept for the major component capacitor matrix has been defined.

Special endeavours have been made to storage maximal energy. Electronic components have been defined with special regard to availability and necessary redundancy. The required energy for the actuators, sensors and control electronics has been defined.

Finally, the charge concept was realized and tested with an electronic circuitry on a prototype.

Findings of the study are published in detail by a final report (German only) which is available online via
