The two of them quickly got into the cabin and made preparations before takeoff in an orderly manner.

Kleger tossed the switches one by one, and then his eyes looked at the engine of the wing on the left.

"Buzz, buzz." A burst of black smoke came out, and a roar came from the engine.

This is not to start the engine, it is just to start the two-stroke engine inside the "bullet"-shaped cone in the middle of the engine air intake.

The jet engine cannot rotate by itself. It must rely on other power to drive it to a certain speed before it can be started. The current method of starting the jet is to use this special starting engine.

Amid the roar of starting the engine, the fuel pump began to pressurize, and efficient aviation fuel was pumped to the six independent combustion chambers in the middle of the engine. At the same time, the 8-stage axial flow compressor in the engine rotated and began to continuously accelerate air and enter the combustion chamber.

When the engine had been driven to 3,000 rpm, Kleger turned the ignition button and instantly injected fuel from the independent combustion chamber. Under the ignition of the spark plug, it burned wildly, and the high-temperature and high-pressure gas pushed the monopole turbine behind and then sprayed out from the tail nozzle.

The ground crew stood in the distance and observed, the inner flame was red and the outer flame became faint, which was normal.

"It's normal for the left to fire." The ground crew shouted in the radio.

Kleger continued to start the right-handed unit. After a few minutes, flames also emerged from the engine on the right, and both sides started normally!

After receiving confirmation from the ground crew, Kreiger observed that each instrument was normal again, and then pushed the throttle rods on both sides forward together.

The turbojet engine made a unique whistle, and this sound made Kleger very intoxicated every time. He stared at the dashboard in front of him. The engines on both sides had reached a maximum speed of 9,000 rpm. At this time, the thrust on both sides exceeded one ton.

The entire plane was shaking, as if it was to be able to fly at any time.

Kleger relaxed his breath and shouted in the radio: "Lightning 7, request to take off."

"You can take off, I wish you a victory."

Kleger released the brakes and at the same time, he pressed the four linkage buttons on one side of the operating lever together.

There are two external plug-in points under the wings on the outside of the engine, which are specially prepared to hang the Walter 109-500 take-off booster rocket.

As he pressed the button, the booster rocket was also igniting violently. Each booster rocket could burst out 500 kilograms of thrust. With two engines, a total of four tons of thrust, pushing the eight-ton aircraft and quickly slide on the runway.

(To explain, the unit of force should be Newton, and tons are units of mass, but in many terms, they like to use how many kilograms of thrust to express. In fact, it should be multiplied by 9.8 to get the thrust value. It is not the heroic layman in East China, but everyone calls it that.)

The lightning bomber began to slide on the runway, and the speed was getting faster and faster.

In fact, even without a booster rocket, lightning bombers can fly, but it will require a longer runway. After all, the takeoff speed required by the jets is very large, and adding booster rockets can effectively shorten the takeoff distance of the aircraft, reduce fuel consumption, and extend the aircraft's range.

In this era, the limit of the piston engine has made the thrust-to-weight ratio of the entire machine reach about 0.4, while the thrust-to-weight ratio of ordinary propeller bombers is only about 0.2. Nowadays, the thrust-to-weight ratio of lightning bombers has reached the thrust-to-weight ratio of the thrust-to-weight ratio of the lightning bombers has reached the thrust-to-weight ratio of the thrust-to-weight ratio of the thrust-to-weight ratio of the thrust-to-weight ratio of the lightning bombers has reached the thrust-to-weight ratio of the thrust-to-weight ratio of the thrust-to-weight ratio of the thrust-to-weight ratio of the lightning bombers has reached the thrust-to-thrust ratio of the thrust-to-weight ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the lightning bombers has reached the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-thrust ratio of the thrust-to-

Both of them felt a huge force coming from behind, pressing them on the back of the seat. At the same time, everything on the ground on both sides was quickly retreating.

The bomber began to accelerate.

The jet is fast, so the pilot needs to have a more sensitive reaction. Kleger glanced at the speedometer with the outskirts of his eyes. When the speed reached 250, he pulled the operating lever backwards.

The wheels in front were lifted up instantly, and the bomber raised his head and continued to slide forward for dozens of meters on the runway. Then, the main landing gear behind also left the runway.

In history, lightning bombers once used a pit rig to take off, but now this method has not been used, it is a normal landing gear.

At this time, the four booster rockets had reached the end of their work. After they continued to burn for a few seconds, the fuel was exhausted. Then, Kleger pressed the release button, and the four booster rockets fell from the wings. The parachute automatically opened and slowly fell to the ground under the action of the parachute.

These booster rockets are liquid-fueled and can be used after they land, disassembly inspection can be continued.

Retrieving the landing gear, Kleger carried the operating rod and continued to climb upward at a small angle. From now on, in addition to considering speed, he also needed to consider fuel consumption.

Compared with mature piston engines, jets are quite fuel-intensive. In history, the me262 can only fly near the airport. Compared with the piston fighter's range of hundreds of kilometers, it is impossible to catch up.

However, now, the progress of German jet engines is quite rapid, with a much lower fuel consumption rate than engines in history. At the same time, one of the advantages of bombers is that they are large in size and can carry more fuel.

The total oil carrying capacity of the Lightning Bomber reaches an astonishing 4,200 liters. The fuel is stored in three fuselage fuel tanks. The two fuel tanks in the front and rear are self-sealed and the fuel tank in the middle does not have any protective measures.

The fuel is enough to support the lightning bomber back and forth to Petersburg, but it still needs to be used.

The altimeter continued to rotate, and soon it rose to a height of 10,000 meters. Kleger leveled the plane, aimed in the direction under the instructions of his partner Janssen, and flew straight to Petersburg.

At a height of 10,000 meters, the lightning bomber became a highlight. The hot gas ejected from its tail spreads rapidly in the atmosphere and cools down, causing some water vapor in the atmosphere to condense, pulling out a white trajectory in the sky.

The engine's speed dropped to 7,000 rpm, and the bomber flew along the route at a speed of 700 kilometers per hour. After half an hour, they caught up with the huge fleet.

At this time, it happened to be over the Baltic Sea, with azure sea below and a blue sky above our heads. The escorted F190 fleet also happened to meet with its own bombers.

"Boss, at six o'clock, I found a new guy." At this time, a pilot in the f190 fleet exclaimed: "It has no propellers!"

Hearing the call from the radio, the captain Heinz-Bar said while breathing the air inside the oxygen mask: "035, pay attention to the radio call discipline."
