Abstract
A system for ground power supply of aircraft includes at least one mobile transformer unit having a first vehicle chassis and a voltage transformer mounted on the first vehicle chassis; at least two energy stores which can be alternately connected to an input of the voltage transformer in order to supply the voltage transformer with electric energy; and a supply cable for ground power supply of one of the aircraft. The supply cable is configured to be connected to an output of the voltage transformer. Each of the at least two energy stores is part of one of at least two mobile storage units each including a second vehicle chassis. The first vehicle chassis of the transformer unit and each of the second vehicle chassis of the at least two mobile storage units are moveable on the ground independently on each other.
Claims23
A ground power supply system for aircraft, the system comprising:
- at least one mobile transformer unit comprising:
- a first vehicle chassis;
- and
- a voltage transformer mounted on the first vehicle chassis, the voltage transformer having an input and an output,
- a first mobile storage unit comprising:
- a second vehicle chassis;
- and
- a first energy store mounted on the second vehicle chassis,
- a second mobile storage unit comprising:
- a third vehicle chassis;
- and
- a second energy store mounted on the third vehicle chassis, wherein:
- the first and second energy stores are configured to be alternately connected to the input of the voltage transformer to supply the voltage transformer with electric energy such that the voltage transformer and the first and second energy stores cooperate to supply continuous ground power to the aircraft;
- the mobile transformer unit is configured for providing ground power supply to one of the aircraft;
- and
- the first, second, and third vehicle chassis are configured to be moved on the ground independently on each other.
A method of providing ground power to an aircraft, the method comprising:
- providing at least one mobile transformer unit comprising:
- a first vehicle chassis;
- and
- a voltage transformer mounted on the first vehicle chassis, the voltage transformer having an input and an output,
- providing a first mobile storage unit comprising:
- a second vehicle chassis;
- and
- a first energy store mounted on the second vehicle chassis,
- providing a second mobile storage unit comprising:
- a third vehicle chassis;
- and
- a second energy store mounted on the third vehicle chassis, wherein:
- the first and second energy stores are configured to be alternately connected to the input of the voltage transformer to supply the voltage transformer with electric energy;
- the mobile transformer unit is configured for providing ground power supply to one of the aircraft;
- and
- the first, second, and third vehicle chassis are configured to be moved on the ground independently on each other;
- attaching the mobile transformer unit to charge the aircraft;
- connecting the first mobile storage unit to the mobile transformer unit so that while the mobile transformer unit is charging the aircraft, the first mobile storage unit is providing electric energy to the mobile transformer unit for use in charging the aircraft;
- and
- after using the first mobile storage unit to provide electric energy to the mobile transformer unit:
- connecting the first mobile storage unit to a charging unit to recharge the first mobile storage unit's energy store;
- and
- connecting the second mobile storage unit to the mobile transformer unit so that while the mobile transformer unit is charging the particular aircraft, the second mobile storage unit is providing electric energy to the mobile transformer unit for use in charging the aircraft.
