Helicopter: all kinds of form of hybrid

Hybrid how to become the industry an important means of decarburization?

According to the group's global strategy, we work for helicopter products around the three complementary areas to reduce carbon dioxide emissions, the use of alternative fuels, high efficiency of the engine combustion chamber, and hybrid.Hybrid is the combination of heat and electricity, and can reduce the fuel consumption of heat engine, thereby reducing carbon dioxide emissions.Our goal is to finish at the end of the 10-year amid the helicopter through a variety of hybrid conceptsLower fuel consumption20%.In addition to the 20% target, our next generation turbine engine fuel consumption and the use of alternative fuels(sustainable aviation fuel)The related income will also increase.

How can I advance the helicopter is motor?

As a medium-range aircraft electric propulsion in the helicopter with 100% of it is not feasible.Considering a helicopter mission required energy density, in addition to the small aircraft, and short flights, pure electric scheme will not be applied immediately.As a result, the combustion engine will still be the mainstream of the market products.However, the next generation of more efficient engines will run by motor, in order to reduce fuel consumption, reduce noise, improve safety and reduce particle emission.It is worth notingA hybrid is a variety of forms!Electric energy can beThe instantaneousUse forDifferent phases of flightAnd according to themodels,voyageandTask categoriesMeet different needs.

Safran helicopter engine company is currently developing what different hybrid concept?

"Eco mode" is one of our development of the first application.It is applicable to double the helicopter.Though and emergency takeoff stage requires a lot of energy, but, in the "cruise" flying helicopters don't need all the power to run the two engines."Eco mode" is included in this stageLet the engine of a binary in sleep.Thanks to safran development the reliable power supply of the motor, the other engine can very quickly drive manually or automatically.This functionality is similar to "start-stop" system of car.Airbus helicopterRACERVerify the machine will be the first use of the system which is a hybrid of the first form,According to different task type has been able to save as much as20%The fuel consumption.

We also is to develop a helicopter as an aid in the form of instantaneous"Electric booster"System.Electricity as a power source of a given time period in this supplement.The solution brought in addition to the energy consumption of a number of advantages, such as reducing noise pollution or particle emissions.This is also a kind of canFor single helicopter standby power supply solution.

In addition, the peak helicopter engine company also from the rest of the group company is totally different from the modern architecture of vehicle developmentDistributed hybrid propulsion system: VTOL (vertical take-off and landing aircraft) and STOL short take-off and landing aircraft (level).First case EcoPulse consists of Daher, safran and distributed hybrid propulsion aircraft airbus design demonstration models, it adopted the peak electrical and power company ENGINeUS ™ motor and the peak power plant turbine generator of the company.Such STOL aircraft equipped withTurbine generator, that is, gas engine, generator and battery combination.The engine provides several electric motor on the wing of the electricity.This is an important project, and the group of companies are developing all the other hybrid concept, it will make you a better understanding of hybrid propulsion's contribution to the future aircraft.

In addition to lower energy consumption, hybrid provide what other opportunities?

In addition to the environmental benefits, hybrid for maintenance costs, emissions and noise of the flight safety has opened up an attractive prospect.Finally, for safety reasons, the laws and regulations are not allowed in the case of an engine failure over European cities.In this type of aircraft equipped with an electric motor will provide power in the event of a failure, enables the pilot to fly to the empty area safe landing.
