Airbus to Introduce autonomous pushback for Future Hybrid aircraft.

Pushback is crucial for the aircraft since it enables them to reverse. since airplane lacks external power to accomplish it. But, Airbus might stop needing the pushback trucks to perform that function in the future.

The nose gear motor, which will boost the electrical power to do so, will enable one of the future Airbus aircraft, which is powered by a hybrid electric, to pushback itself without the assistance of a pushback vehicle. As soon as the last aircraft has finished pushing back, the same electric energy fuels the turbines, which then run the propeller and generate enough thrust to move the aircraft forward.

At Airbus, hybrid electric power can cut CO2 emissions from airplanes by up to 5%. Although they are often lighter than fixed-wing aircraft, helicopters could account for as much as 10% of the total. Airbus is leading a cross-industry effort to make hybridization a reality because it represents a significant milestone in the aircraft industry’s decarbonization path.

A variety of innovative solutions that combine novel fuel types and emerging technologies are needed to decarbonize flight. Hybrid-electric propulsion is one such option that can increase the energy efficiency of all aircraft classes.

A single mechanical power source powers the propeller or fan in a serial architecture. Several sources of power exist besides batteries. Alternatives exist, such as hydrogen fuel cells. In any instance, dispersed propulsion is made possible by the propeller being always driven by an electric motor.

As far as hybridization is concerned, this is serial architecture’s biggest advantage. But it means adding weight in the shape of a generator, to convert mechanical power to electrical power.

In a parallel architecture, the gas turbine sometimes operates below peak efficiency. However, a smaller and lighter electric motor is enough to meet the requirements. So a parallel architecture is better suited to hybrid applications. What about the battery that powers the electric motor sitting within it?

Airbus Charging options

Whatever the technology, batteries need to be charged. For commercial aviation there are three options: swapping depleted units for new ones on the ground; or installing charge points at the gate, potentially using renewable energy. The latter requires investment in infrastructure but in the long term, this would be offset by fuel savings.

Thirdly, where ground infrastructure is lacking, the aircraft’s engines could recharge the batteries during the cruise phase of a flight. “The reality could well be a mix of all three,” says Segura, “depending on individual airline and airport choices.”
