Is it possible that airliners can also be made electric like cars?

Over the past decade or so, we've seen many industries look to transition to renewable energy, and while we've made tremendous strides in the production of renewable energy, the technology that has made it possible for every industry to use renewable energy hasn't kept pace. Theoretically, if we had a reasonable way to store energy effectively and efficiently, many coal-fired power plants would disappear.

This energy storage dilemma is slowing our adoption of renewable energy, and one of the most obvious industries is the aviation and space industry. While Elon Musk has worked hard to promote electric vehicles and solar products, he burns more than 100 tons of fuel every time he launches Space X on a Falcon 9 rocket.

Because there is a huge hurdle that the aviation industry needs to overcome in order to successfully adopt renewable energy. This obstacle is the energy density of stored electrical energy. Energy density is a measure of the amount of energy we can utilize from a certain volume or mass of energy.

For kerosene for aviation, the energy density of lithium batteries used for electric vehicles is much smaller, about 1 40 times that of kerosene. For the same amount of energy, the weight of the battery is much greater than that of kerosene.

This obstacle is a huge problem. When the lift of the aircraft is equal to the gravity of the aircraft, the aircraft will fly, and to meet this condition, the weight of the aircraft will increase greatly with the use of batteries. As the weight of the aircraft increases, the more energy is needed, and the batteries need to be added.

Obviously this is a vicious circle.

Let's compare the feasibility of using batteries between two aircraft, the Airbus A320 and the Cessna. For example, both planes fly for four hours. Airbus needs a battery that weighs about 150 tons, which is twice the weight of the plane itself, and the kerosene used to fly this far is less than 10% of the weight of the aircraft.

The Cessna needed a battery that weighed about 500 kilograms, which is equivalent to two-thirds the weight of an airplane.

I think it's still possible, but I don't think it's necessary to make it electric.

Passenger planes already have electric ones, and many buses are now new energy electric.

There are many things that need to be paid attention to in the operation of passenger aircraft, and the risk factor is high, and it cannot be made electric.

It's unlikely, after all, it takes a lot of energy to motivate him.

This bar may be in the future, and now the technical cost is too demanding.

The possibility of making it electric is very small, because airliners require a huge amount of energy.

I don't think that's possible, after all, airliners require a lot of energy.

Anything is possible, and it will take time.

I think anything is possible, but it takes a certain amount of time, and the development of science and technology takes time.

We all know that it is very difficult for a pure electric aircraft to carry heavy objects or a large number of people, power output and power storage are the current problems, and the current pure electric aircraft can only carry very light objectsSo could an all-electric aircraft become a reality? How far away is it? Purely electric aircraft are already a reality, but it is very difficult to use them for air transport at the momentLet's break it down.

First of all, we know that if the plane wants to fly into the sky, it must have a good streamlined fuselage, coupled with a light structure and strong power, and our aircraft can only fly to the sky. At present, the aircraft adopts more propellers and jets, and the power output mode mainly relies on aviation kerosene, and relies on the internal combustion engine to drive the engine to produce power on the blades, which is the traditional aircraft launch mode. Pure electric aircraft have become a reality, but due to the power reserve and power output, they have not yet achieved very good results, so they are not used in a large area.

It is precisely because of the short endurance time of pure electric aircraft and the uncertainty of the output efficiency and performance of electric energy, so many aircraft rarely use pure electric aircraft, and the general use of pure electric aircraft is mainly small UAVs and personal vehicles. It is still difficult for pure electric aircraft to achieve a large number of passengers and cargo transfer, because the power output, power reserve and transmission efficiency are still in a very low stage, so pure electric aircraft are likely to become a development trend in the future. The primary guarantee of the aircraft is safety, if the aircraft has a short endurance and does not have a good transmission efficiency, then there is no need to use a pure electric aircraft.

In the future of human technology, if human beings have made breakthroughs in all the technologies of pure electric aircraft, it is very likely that pure electric aircraft will be the main mode of transportation in the future. After all, electricity is the cleanest energy source, and the use of jet fuel will also cause certain harm to the environment, and we hope that one day it will become a reality.

Yes. Because with the development of technology, pure electric aircraft should become a reality. Because the current battery technology is becoming more and more mature, it is not very far away from us.

An all-electric aircraft could become a reality. Because of the rapid development of science and technology, there are now pure electric cars. As long as solar technology continues to develop, there will be all-electric aircraft one day in the future.

It is very likely that a purely electric aircraft will be realized, and such an aircraft will achieve this short-distance flight mode, which is about 100 or 200 years away from us, and this wish can be realized slowly.

It has become a reality, and Slovenia's Batplanes already have pure electric aircraft.

On 12/10/19, a pure electric propeller aircraft was developed.

I'm almost done with the electric airplane drawings. I'm the only one in the country who can do it.
