American BMP Bradley will receive a hybrid power plant instead of a diesel

American Bradley infantry fighting vehicles in the near future will receive hybrid power plants instead of diesel ones. According to the British company BAE Systems, the company's specialists will modernize the American tracked infantry fighting vehicles, reports NPlus1.

BAE Systems has signed a contract with the US Army to create a modernized version of the Bradley combat vehicle. In the course of work on the new version, it is planned to equip the BMP instead of a diesel hybrid powerplant with electric drive wheels. According to the company, this improvement will make Bradley maneuverable, easier and more economical. In addition, the hybrid installation will eliminate the heavy hydromechanical control system and install a lighter and more reliable fly-by-wire system.

The American Bradley infantry fighting vehicle was adopted in 1981. Machine weight - about 28 tons, length - 6,6 meters, width - 3,6 meters, height - 3 meters, speed - up to 56 km / h, covered distance - up to 400 kilometers. The machine is equipped with a 903 hp Cummins VTA-600T diesel engine. The transmission of the machine is made in a single unit with the engine and has three fixed gears forward and one backward. The gear shift is automatic. Front wheel drive with pinned track engagement. Sloths with hydraulic track tensioning mechanism are located at the rear.

Details on the composition of the hybrid propulsion system have not been specified. It is also unknown when the first prototype with a new power plant will appear. The only thing that is known for certain is that after the successful completion of the prototype tests, it is planned to equip all Bradley vehicles with a hybrid propulsion system.

All of these advantages are good for a civilian passenger car, not for military vehicles.

All these benefits are good for a civilian passenger car.

Reducing the mass, for example, will allow you to visit additional weapons or armor. As I understand it, the scheme is that the same diesel engine acts as an energy source, it is simply transmitted to the chassis through electric motors. And if so, then the transmission, it turns out, can be thrown away (at least in its classic form).
Such pribluda have long been used in shipbuilding, for example.

[dzvero]

And also on diesel locomotives and dump trucks.
The advantages of the circuit are more "freedom" of the layout and more torque of the electric motors. Efficiency is achieved due to the operation of the diesel engine in the optimal mode. But the mass of the generator is commensurate with the mass of the transmission. Personally, I am not sure that such a scheme will eventually be "registered" on the BMP / BTR.

Logical.

You can also accumulate energy at the moments when the car is moving by inertia, down a hill, etc. But then you need a normal battery.

I have no idea. I admit that it may not be so, in some cases

[prodi]

have been poking for a long time, including ours.
The main idea: to throw out the transmission, put the generator and a small battery, which, together with a smaller diesel engine in size and power, will (briefly) even exceed the previous power plant

[Lopatov]

Plus, the engine will constantly work in the optimal mode for it. Which will reduce fuel consumption and increase the resource

[Ryaruav]

and it's enough to remember Ferdinand / Elephant, there is also an electric transmission

[chenia]

What about the electric motor?

If we do it according to such a scheme, it is wheeled armored personnel carriers, instead of a bunch of shafts and transmission
And it is possible to have a wheel-motor.

[zwlad]

Throw out the transmission. Deliver the generator. And who knows what is easier.

[iouris]

The main advantage: it is problematic to use at low temperatures.

Huh ... With such a power-to-weight ratio, launching at low temperatures will not be a problem.

[Maz]

I look at his tower hung with observation instruments and think that if you take the Kord 12,7mm or DShK or Utes and give the heels of bursts of armor-piercing bursts on this tower, the crew will go blind at the moment. And the car will not be combat ready. I would like to check.

Any alternative / incl. hybrid / power plants are relentlessly advancing. Both in the automotive industry and in military technology. With the development of technology, they become more and more competitive.

[Grazdanin]

Europe's refusal from fossil energy sources has already been indicated, a ban on new cars with internal combustion engines in some countries comes in 5-10 years.

[pytar]

Yes, the process has started and it cannot be turned off. By the way, because of him, in Europe, you can buy an almost new (used) car for a dvg, at an extremely low price. Diesel prices have dropped especially!

No need for pain. In Russia, hellish import duties. We can only lick on European cars here.

Why do you need this European junk? I was recently offered a four station wagon with a mileage of only 2,5 million km. without overhaul for mere pennies. It is a solid device, and no customs clearance is needed.

Dear Bulgarin. No one questions the disposal of all this ecological pribluda, we leave everything for later. Very good memories of communicating with Misha, a sailor from the Slanchev Bryag refrigerator off the coast of Mauritania for six months. Good luck!

[pytar]

Hi Andrew! The issue of disposal just comes first! They take it into account and work on the topic! There is no doubt that solutions will be found, and even now technological processes are intensively developing in this direction! Colossal resources are being redirected to alternative sources of energy and ecology! Good luck to you too!

To have doubts, you need to have your head on your shoulders. The one who broadcasts with agitation is clearly not from this category.

Doubts are dispelled when, in addition to the head on the shoulders, there are also brains in it!

A sign of the presence of brains is thoughts.
And in the absence of those very thoughts, some stuff the empty space with slogans. Like a bag in a display case. To give the appearance, at least, appropriate.

By the way, you didn't even understand what the topic of the article was. Seeing the familiar phrases, we hurried to convey to the venerable public another portion of slogans, which, with a closer reading of the article, cannot be sewn to it like a sleeve to a well-known organ. It's funny.

The non-thinker will not understand the thinking one. As a blind person who sees and as a deaf person who hears.

And in the absence of those very thoughts, some fill the empty space with slogans.

Something more concretely on the topic? Like, what is not how and why exactly ...?!

By the way, you don’t even understand what the topic of the article is.

I am not one of those who tend to blame all the blame on propaganda, justifying the deceived by it.

[Free wind]

I am for electric trains. But to use it in military equipment ... well, I don't know. Of course, this hybrid is only in the project.

Technological progress makes it possible to reduce the disadvantages and enhance the advantages of such systems.
It is enough to look at the history of military technology and the trend becomes clear.

What distinguishes equipment for the military from civilians is precisely its reliability and reliability, and also maintainability. Hybrid technology cannot boast of such qualities.

Look at how much equipment was produced in a single copy, how many projects were closed, just because of the excessive complexity of the service.

[rocket757]

Heavy weight, heavy loads, extreme conditions ... are they going to use highways only?
Whenever, when there are new design solutions, new movers will be in demand! In the meantime, this is only for the sake of green and certainly not for general distribution!

[Rostislav]

In the meantime, this is only for the sake of the green

This is not for the sake of the "green", it is for the sake of the imposed opinion about the supposedly greater environmental friendliness of hybrid engines.
The same diesel fuel is used as fuel. And copper smelters (armature and stator winding) are another "gift" of ecology. So if you look at the entire production / operation chain impartially, then the question is which of the engines is closer to the "green" one. The hybrid is more economical, this is so, but in all other respects there are many questions to it, both in terms of reliability and in terms of operating costs.

More economical under certain optimal conditions. When the operating load interval is wider than driving on good roads, things are not so good, if you really understand.
About other hacks that are, after all, nobody really cares! Greener, more economical, more modern and that's it.
In the future, some problems will be resolved, but not immediately.

[TAMBU]

what they donated - that's what's interesting ... just a place or some other systems?

Well, yes, and also an optitronic display, LED feet, an all-format radio tape recorder, repeaters of turns in the mirrors, tumanki, automatic light on at nightfall, anti-skid function, start-stop function, multi-function display, ECO mode, and so on, but in addition .. everything will be, except for the starter and the brains of the mechanic ..

The more systems technology there is, the greater the probability of failure.

If these systems are duplicated, then vice versa.
In a hybrid, you can duplicate everything except the engine-generator (although it is also easy to parallelize).

[Ros 56]

That's how it is, only what to do with the additional mass, so it comes out, where do not throw a wedge everywhere. Gears, bearings will start flying, power elements crackle, control severity, inertia, etc.

[Genry]

Quote: Ros 56

just what to do with the extra mass

Where does the extra mass come from? You can simply divide one element into several (electric motors, power electronics). At the same time, if one of the nodes fails, you will receive only a partial loss of mobility.
In the hybrid version, the flywheel, clutch, gearbox and distributor, all shafts (iron bouquet) are thrown away. A generator, electric motors and batteries will be added (they will add functionality such as: a quick escape from fire when the engine is cold or a jerk when overcoming an obstacle - what the diesel engine lacks).
Moreover, everything becomes simpler and easier to repair due to modularity. Fewer power fixings and joints.

[Ros 56]

Do you in a design office work with such knowledge or just a theoretician with a technical bias?

The French installed the electric transmission on the Saint-Chamond - and since then nothing has changed ...
