Chapter 1099: Diesel reconnaissance aircraft

2.6 million is just an army that has entered the front line. Germany has already begun to mobilize for this war. Many workers on the production line have been transferred to the army. The vacancies are filled by other personnel, and even some women have joined the army. Job position.
In the rear, Germany is still training at least about 2 million troops. They can step onto the battlefield at any time when needed, and shed their last drops of blood for Germany!
The time for the war to start is getting closer and closer.
Poznan Air Force Base, Poland.
As early as six months ago, the air force base here has been expanded. The main runway is more than 2,000 meters away. Not only ordinary fighters can take off, but even large aircraft can take off and land without problems, even including Junker-390. big guy.
And now, at the take-off 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 slightly twisted. There are two engines at the roots of the wings on both sides, driving four-blade propellers. Its cockpit, how much It is composed of blocks of glass and has a good view.
At the tail of the fuselage, there is a cocked tail, and on both sides of the tail, there are two vertical tails, which looks even more exotic.
Captain Lucas, wearing a full set of flight equipment, carrying a suitcase in his hand, and his crew, came to the plane.
"Captain, the plane is ready, it's full of fuel, the photo film is full, and the automatic equipment is completely normal." The ground crew said to him.
Lucas nodded and climbed into the cockpit from the narrow space under the nose. Behind him, several crew members also boarded the plane one by one.
Turning on the switches, Lucas observed that the instrument data was normal, and then ordered the pilot beside him to start the engine.
"Da, da da da..." The engine on one side made the special sound of pumping oil from a high-pressure oil pump, a puff of black smoke came out of the exhaust pipe, and the propeller turned.
The vibration of this kind of engine is much larger than that of a normal airplane engine. It is not the sound that a gasoline engine can have at all, it is a genuine diesel engine!
Yes, there are still some different kinds of German aircraft. For example, this Lucas aircraft is an extremely special long-range reconnaissance aircraft, the JU-86P.
From the code name, it is very close to Junker-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-range reconnaissance. effect.
This kind of aviation diesel engine is saturated with 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 already practical.
Gasoline engines are powerful and responsive, and are outstanding aerodynamics. Almost all countries in the world have chosen aviation gasoline engines. However, Junkers has taken a different approach and adopted aviation diesel engines with its advantages.
The fuel consumption rate of the diesel engine is quite low. With the same capacity of fuel, the working time of the diesel engine can be more than twice that of the gasoline engine, which can significantly increase the range.
Specifically, when the speed reaches 180 knots, only 20 gallons of diesel is consumed per hour. Historically, when the auxiliary fuel tank was used, this type of aircraft once sailed to Australia. The total range is 23,335km, and the total flight time is 69 flight hours.
In terms of endurance, even the Junker-390 is far behind.
Another advantage is that diesel engines work more stably at low air pressure. In the case of thin high-altitude air, gasoline engines need a two-stage supercharger to work normally, and the demand for diesel engines is very low.
With this idea, Junkers developed the Jumo205 series and Jumo207 series of aviation diesel engines, but unfortunately, the demand for this diesel engine was not high. In the end, it was only installed on the Junkers Ju86 aircraft for use and became the Ju86. The distinctive sign.
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 meters again and after confirming that there was no problem, he gently released the brakes.
The engines on both sides vibrated more violently, the propellers spun, and the JU-86P began to roll on the runway.
The diesel engine has high torque, but the power is not enough. Now the engines on both sides can only burst out 1000 horsepower, which makes the acceleration of the aircraft not smooth.
The reconnaissance plane, full of fuel, barely pulled up almost in the middle of the runway, and then began to climb slowly.
One hundred meters, two hundred meters, five hundred meters, one kilometer...The altimeter has shown 10,000 meters. In this era, this is already the ceiling of many high-altitude fighter jets.
However, it is not high enough for this reconnaissance plane!
It is slowly climbing upwards.
Eleven thousand one, twelve thousand, thirteen thousand... when it climbed to 14,000 meters ~EbookFREE.me~ finally leveled off.
Yes, it is 14,000 meters. Even at the end of World War II, only TA-152 fighters can reach the height!
At such a height, the JU-86P reconnaissance aircraft is absolutely safe. Therefore, this aircraft does not carry any weapons, and it does not even have a turret at the tail. Its survival king is altitude!
In later generations, whether it is U-2 or SR-71 Blackbird, their way of survival is to fly higher!
After the leveling, the diesel engine was finally reduced in power. At this time, the temperature of the engine was already very high.
The diesel engine runs smoothly. At this altitude, it does not feel the lack of oxygen in the air.
In the end, the plane stabilized at a speed of 350 kilometers per hour and started the long flight.
To the east, flying over the border, flying over Belarus, flying over Moscow, and all the way to the Ural Mountains, along the way, thousands of investigative photos were taken for rear use.
Over the years, the relationship between Germany and the Soviet Union has been good and bad, and as a soldier in the Empire, it is his bounden duty to obey orders. Therefore, Lucas has no psychological pressure on this kind of reconnaissance flight.
Even the Soviets can't find them at all. The Soviets in this era have not yet developed a mature and reliable radar!
As time passed a little bit, they flew over Warsaw, and the other side was already in Soviet airspace.
"Navigator, pay attention, adjust the direction in Warsaw. We need to take more pictures 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. Inside, several high-precision aerial cameras began to prepare for taking pictures. ()
