In addition to helping the motorcycle factory, the automobile factory is also very busy itself.
After the floating island took off, there was a problem with the railway's capacity. The train was powerful and had little advantage in running short distances. Grouping cargo was a waste of time. By this time, the trucks had already arrived.
So the car factories are a bit busy with orders.
Even when I was busy, I did not forget to develop new products... In fact, the main reason was that I was too busy. Orders were queued up for several months, and there were still people queuing up, so I had to find ways to reduce the load.
The goal of the new product is to target a gap in the market and be able to use diesel engine types.
Today's road vehicles include classic cars (sedans), vans, and heavy trucks. Single-cylinder tractors used in workshops are not included.
The van was produced in the Wind Valley Industrial Zone, and the classic car was produced in Blackwater. Both were based on Blackwater's annexation into the Kingdom, and both had received certain technical support from the car factory.
Both cars initially had their engines produced by car factories, and later changed to authorized production, and finally they were improved by themselves.
Among them, the van factory made rapid progress with the blessing of the Fenggu industrial chain, and soon had its own four-cylinder gasoline engine. Later, the Heishui depot directly introduced their gasoline engine.
The difference between a gasoline engine and a diesel engine mainly lies in multiple igniters. This thing was made by the van manufacturer for help from the mechanical and electrical plant. The four-cylinder can be used, but the speed cannot be too high. The reliability of the ignition needs to be improved, and maybe there is oil. pot.
Both manufacturers choose gasoline engines because the compression of gasoline is relatively small and the piston stroke is short, which reduces vibration and noise, and is more friendly to light vehicles with insufficient weight.
Xincheng Automobile Factory did not follow this wave of participation. Their purpose of establishing the factory was to build the best diesel engines. It did not matter what kind of gasoline engines they developed.
Automobile manufacturers have been researching and developing diesel engines for a long time and have accumulated many diesel engine models. However, on the sales side, inline six-cylinders are still used.
The inline engine has a simple structure and is extremely reliable. It basically won't break. If it can't move, take the engine apart, boil it in water and dry it, rub it with oil and assemble it to create a new engine.
The disadvantage is that it is relatively heavy and long, so it is not suitable for small and medium-sized vehicles.
Therefore, the models developed in the direction of inline engines are very limited, only inline four and inline six. A prototype of the in-line eight was once made, but no one cared about it after testing. Trucks are not trains. On trains, engines that are six or eight meters long can find a place to put them. In trucks, there is no place to put transmissions that are longer than two meters.
In addition to specializing in in-line engines, automobile manufacturers have also studied V-type engines.
Because there is no finished car product, there is no need to classify it by model. It only counts the number of cylinders, and there are three types: V4, V8, and V12.
The V12 was developed with the intention of producing a high-end heavy truck.
The existing inline six has a power of just over 200 kilowatts, which translates into less than 300 horsepower.
The car factory's V12 prototype can already produce 450 horsepower, but it has problems from time to time during endurance testing, and it doesn't work well with the gear set, so it has been modified.
V8V4 has a smaller horsepower number, but its structure is relatively simple and the finished product is more reliable.
V4 engines have been sold for a long time, but there is no comparison between the early model and the current model. There is a difference in horsepower between 60 horsepower and 110 horsepower.
After going through the process of demonstration and reporting, the car factory decided to follow the old path and sell V4 engines and their transmission sets instead of building complete vehicles. ….
It is also because there are many types of semi-trailers for heavy trucks and the demand is not small. The manufacturing hours of these big guys are relatively long. In addition to their own tasks, the automobile factory also undertakes the production of some radial engines from Blue Sky Heavy Industry. If we open another medium-sized truck production line, there are not enough skilled workers. Selling engines and transmission sets will help us get the product off the ground earlier.
When it comes to Blue Sky Heavy Industries' radial engine, they are also ambitious.
The managers at the car factory were a little trembling when they went to talk, fearing that a leak would happen in their factory and cost them their heads.
But Blue Sky Heavy Industries has a good reason. Their current engine department’s production capacity is not enough, and they can only make water-cooled machines, so they want to entrust the air-cooled machine to the automobile factory. They also said that if the civil aircraft factories of Hongshi and Fenggu are willing Buy or sell.
The water-cooled engine is caused by the insufficient load capacity of the airfoil of the twin propeller type of the Tornado III.
The engine used by Guangfeng III has a single power of 400 kilowatts, and two of them can pull it to a speed of 450 kilometers per hour.
This kind of engine has nine cylinders in one turn, but it is still nine cylinders in a staggered position on the second turn. The total of 18 cylinders only makes up 400 kilowatts. The actual power of a single cylinder is not as good as the level of an inline four from a car manufacturer. As long as the number of cylinders is violently piled up, the power can be increased, and it is normal to not finely polish the output of a single cylinder.
Blue Sky Heavy Industries has not really given up on the dual-engine solution. After all, the dual-engine design has brought better battlefield reliability.
When looking for a solution to the problem, a 14-cylinder solution was also proposed, that is, 7 per revolution. The slightly increased cylinder size ensured that the output remained unchanged while slightly shrinking the engine by one revolution.
Through this change, coupled with the change in the shape of the engine nacelle, a lower engine attachment point can be connected directly from the wing structural beam.
...It is not practical and will die in the direct demonstration stage.
Because according to feedback from pilots, if there is extra space in the engine compartment, the landing gear should be integrated into it to reduce the additional drag caused by the landing gear folded under the wings, and this thing also affects high-speed maneuvers.
After a lot of fiddling, the most realistic solution is to use water cooling. As for the landing gear issue, the wing roots can be stuffed in by making them thicker.
Two-turn cylinders are the limit of air cooling. If you change it to water-cooling, three or five turns are no problem.
The paper work and trial production of water cooling went very smoothly. Only three samples were stacked, and the power increased from 750 kilowatts to 1050 kilowatts.
After several more sample optimizations, the final version was decided on 1080 kilowatts.
This machine also has 7 cylinders per revolution, a total of 4 revolutions and 28 cylinders!
The machine placed on the nose is thicker than the one under the wing, so it can increase the power by 1.5 times on the basis of doubling the number of cylinders. The water cooling itself only allows the cylinder to reduce thermal attenuation and prevent overheating and explosion. It cannot produce additional power.
[By the way, the best one for reading and listening to books is @@, install the latest version. 】
When the air-cooled engine was handed over to the automobile factory, Blue Sky Heavy Industry's improved version of the Tornado three-single engine had already received orders from the military.
This fighter does not have a synchronized machine gun, so it can still only mount the cannon like the twin-engine version, but its wings are completely free and four 500-kg mounting points are provided. With a power increase of nearly 300 kilowatts, it is completely possible. Carrying three tons of weapons into the sky.
It's a pity that 1080 kilowatt water cooling has just been released and is about to become outdated.
Because Blue Sky Heavy Industry is making a more fun toy, a turboprop!
The development history of aviation engines should be V-shaped, star-shaped, jet, and turbojet. The so-called turboprop is actually a subsonic downgraded fuel-saving version that only came into being after the emergence of turbojet.
The efficiency of the jet engine is extremely low. It can be said that it is the best in the history of aviation engines. It consumes 300 liters of fuel per 100 kilometers, which is not a big deal. If there is any advantage, it must be that the structure is extremely simple, with two metal barrels. Just insert the fuel injector and you're done.
Precisely because the oil burned too much, which seriously affected the range and bomb load ratio, huge investments had to be made to develop turbojet.
Finally, the one that truly combines the advantages of load ratio and fuel economy fell on the turboprop. The disadvantage is that it cannot go supersonic, and even high subsonic speeds are almost impossible. However, it is still faster than the existing radial engine propellers, breaking through seven One hundred kilometers per hour depends on it.
Someone was cheating, so Blue Sky Heavy Industries didn't touch the jet at all and just jumped in the middle.
Of course, it spans a generation. Although it is not a true vortex jet, it is not easy to study. We even hired mages from the research institute to help find shortcuts in spells. .
