#1101 Diesel Reconnaissance Aircraft (Plus 4)

2.6 million is just the army that entered the front line. Germany has begun to mobilize in advance for this war. Many workers on the production line have been recruited into the army, and the vacancies have been filled by other personnel, and even some women have joined the army. jobs.

In the rear, Germany is still training at least about 2 million troops. Once needed, they can go to the battlefield at any time and shed their last drop of blood for Germany!

The time for the war to start is getting closer.

Poland, Poznan Air Base.

As early as half a year ago, the air force base here has been expanded. The main runway is more than 2,000 meters. Not only can ordinary fighter jets take off, but even large aircraft can take off and land without any problem, even including Junkers -390. big guy.

And now, at the takeoff end of the runway, a large plane is preparing for departure.

This large aircraft is somewhat different from the existing aircraft in Germany. Its fuselage is slender and the shape of the wings is somewhat twisted. There are two engines at the root of the wings on both sides, driving four-blade propellers. Its cockpit has many It is composed of pieces of glass and has a good field of vision.

The tail of the fuselage is a raised tail, and there are two vertical tails on both sides of the tail, which makes it look more alternative.

Captain Lucas, wearing a full set of flight gear and carrying a suitcase in his hand, brought his crew to the plane.

"Captain, the plane is ready, full of fuel, full of photo film, fully automatic equipment is completely normal." The ground crew told him.

Lucas nodded, climbed into the cockpit from the narrow space under the nose, and behind him, several crew members also got on the plane in turn.

Turning on the switches, Lucas observed that the instrument data was normal, and then ordered the pilot next to him to start the engine.

"Da, da da..." The engine on one side made the special pumping sound of the high-pressure oil pump, black smoke came out from the exhaust pipe, and the propeller turned.

The vibration of this kind of engine is much larger than that of ordinary aircraft engines. It is not the noise that a gasoline engine can have at all, but an out-and-out diesel engine!

Yes, among the German aircraft, there are still some outliers, such as this one of Lucas, which is an extremely special long-range reconnaissance aircraft, the JU-86P.

Judging from the code name, it is very close to the Junkers-88. When this aircraft was developed, it was indeed considered as a bomber, but now, this improved aircraft has played a huge role in long-distance reconnaissance. effect.

This aviation diesel engine is soaked in the efforts of Dr. Hugo Junkers, the founder of Junkers. As early as 1910, Junkers began to develop lightweight aviation diesel engines based on heavy industrial and marine engines. . By 1930, aviation diesel engines were practical.

The gasoline engine has high power and sensitive response, and is an outstanding aviation power. Almost all aircrafts in various countries choose aviation gasoline engines. However, Junkers has taken a different approach and adopted aviation diesel engines, which also has its advantages.

The fuel consumption rate of the diesel engine is quite low. Under the same capacity of fuel, the working time of the diesel engine can be more than twice that of the gasoline engine, so that the range can be significantly improved.

Specifically, when the speed reaches 180 knots, it only needs to consume 20 gallons of diesel per hour. Historically, such aircraft have sailed to Australia when the drop tanks were used. The total range is 23,335km, and the total flight time is 69 flight hours.

In terms of endurance, even the Junkers-390 is on par.

Another advantage is that the diesel engine works stably at low air pressure. In the case of thin air at high altitude, the gasoline engine needs a secondary supercharger to work normally, and the demand for the diesel engine is very low.

Under this idea, Junkers developed the Jumo 205 series and Jumo 207 series aviation diesel engines. Unfortunately, the demand for this diesel engine is not high, and it was only installed on the Junkers Ju 86 aircraft for use. , which became the distinctive symbol of Ju 86.

And this kind of aircraft has only one mission, which is to conduct long-distance reconnaissance!

After the engines on both sides started normally, Lucas checked the various instruments again, and after confirming that there was no problem, he gently released the brakes.

The engines on both sides vibrated more violently, the propellers flew, and the JU-86P began to roll on the runway.

The diesel engine has high torque, but insufficient power. Now the engines on both sides can only produce 1,000 horsepower, which makes the acceleration of the aircraft not smooth.

The reconnaissance plane, loaded with fuel, barely pulled up almost in the middle of the runway, and then began to slowly climb.

100 meters, 200 meters, 500 meters, 1000 meters... On the altimeter, it has already shown 10,000 meters. In this era, this is already the ceiling of many high-altitude fighters.

However, not high enough for this reconnaissance plane!

It is still climbing slowly.

11,000, 12, 13... When it climbed to 14,000 kilometers, it finally leveled off.

Yes, it is 14,000 kilometers. Even at the end of World War II, only the TA-152 fighter can reach it!

At such a height, the JU-86P reconnaissance aircraft is absolutely safe, so this aircraft does not carry any weapons, not even a turret at the tail, its survival king is height!

In later generations, whether it is U-2 or SR-71 Blackbird, their way of survival is to fly higher!

After leveling, the diesel engine was finally reduced in power. At this time, the temperature of the engine was already very high.

The diesel ran smoothly, and at this altitude, it didn't feel the oxygen deficient in the air.

Eventually, the plane stabilized at 350 kilometers per hour and began the long flight.

To the east, over the border, over Belarus, over Moscow, and all the way to the Ural Mountains, along the way, thousands of reconnaissance photos will be taken for rear use.

Over the years, the relationship between Germany and the Soviet Union has been up and down, and as a soldier of the Empire, it is his duty to obey orders, so Lucas has no psychological pressure at all for this kind of reconnaissance flight.

Even the Soviets couldn't find them at all. The Soviets in this era have not yet developed a mature and reliable radar!

Little by little time passed, and they flew over Warsaw, which already belonged to Soviet airspace.

"Navigator, pay attention, in Warsaw, we need to take more photos of the deployment of the Soviets here." Lucas said: "Check our camera equipment, ready to work!"

The hatch in the middle of the fuselage opened, and inside, several high-precision aerial cameras began to prepare for photography.
