Chapter 1227 (1/2)

Flying snake fighter has never been prepared for high altitude. For example, the engines used in flying snake fighters now do not have superchargers at all!

The flying snake fighter uses the v-1710 produced by Alison engine company. This engine has been developed since the 1930s. At first, it was even used in airships. It is a suitable aviation engine.

But it has a disadvantage, that is, there is no supercharger.

During the development, this engine is also equipped with a supercharger, but it is also the most primary primary supercharger, which does not greatly improve the performance of the engine. The flying snake fighter was originally designed to be used at medium and low altitude, so it even directly abandoned the supercharger in the later models.

This is also a prominent defect of this aircraft. It can only be used in airspace below 5000 meters. In the technical data, the practical ceiling of flying snake fighter is only 5810 meters. As for its engine, the effective working range is also below 4600 meters.

In fact, even the P-51 equipped in the U.S. Army Air Force was equipped with the same Allison liquid cooling engine only equipped with a primary supercharger in the early stage, resulting in poor high-altitude performance, but the P-51 has a more advanced intake configuration and overall layout, which greatly improves the cooling and aerodynamic efficiency, and is incorporated into the laminar flow wing design to further strengthen the high-speed performance.

It was not until the British Merlin engine with a two-stage and two-speed supercharger was refitted that its high-altitude performance improved by leaps and bounds.

In the later model of the P-39, the ceiling has also reached tens of thousands of meters, which is to improve the aircraft engine to the standard of primary supercharger, but it is still not an altitude fighter, and its performance at an altitude of 10000 meters is quite poor.

For piston fighters, the high-altitude air is thin. If the aircraft engine wants to work normally, it must have an efficient supercharger. When the intake air is insufficient, the engine will not work.

(East China hero is also very strange. At the beginning of World War II, it seems that American aeroengine technology was not very good. It took the Merlin engine of Britain to get up tall. Sure enough, Britain, an old capitalist country, has a deep foundation.)

Different from history, in this era, due to the rapid development of aircraft high-altitude technology in Germany, the United States is also constantly developing new high-altitude superchargers so that aircraft can fly higher, including the engine of flying snake equipment is also being improved.

But this does not include flying snake. When it is not popular at home and is about to become a special export aircraft, Bell company does not need to improve it step by step.

It is the king of low and medium altitude, that's all.

Now, Roy is in a trance and competes with each other. He climbs up, and all of a sudden, he climbs to a height of 4000 meters. At this time, the aircraft engine has begun to perform because it can't absorb enough air. If he climbs up again, the engine will stop.

Roy knew he couldn't climb any more, and at the same time he knew that if he finished climbing first, the other party would catch up.

The only way is to turn into a dive immediately and get rid of it!

Roy pushed the joystick, the fighter changed out of the climb state and began to dive down.

Now Roy only hopes that the other party can delay finding his dive, so as to open the distance and how he can maneuver, it's easy to say.

Moreover, there are fighters taking off one after another in the Soviet Air Force base. The number of these German fighters is not large. If they know it, they should return.

At this time, on the runway of the base, Safonov's fighter has soared from the runway, the accelerator is fully open, the engine is roaring, and this thick, short and cute fighter is climbing at full power.

Safonov's hand kept shaking the operating lever to try to retract the landing gear of the fighter. It was the first fighter in the Soviet Union that could retract and retract the landing gear, but it was the most pitiful manual operation. Every pilot trained the Kirin arm in retracting and retracting the landing gear, and the arm was as powerful as the Kirin arm.
