Chapter 380 (1/2)

Although it does not take a long time to replace the engines of the three aircraft, Qiu division and their base also sent relevant technicians to Tiangong technology to cooperate with the technicians of Tiangong technology to replace the three non motorized engines.

This shortened the replacement time that would have required at least half a month by at least half. In just one week, Tiangong technology replaced the engines of the three aircraft.

With the completion of the engine installation, Qiu Shi's base immediately conducted a test flight of the three aircraft. The results showed that whether the TG-001 or tg-002 turbojet engine or tg-wsx2 aircraft were used, the overall performance of the aircraft was much better than that before the engine was replaced.

However, compared with the plane with tg-wsx2 engine, the maximum speed can only reach Mach 2.8 and the maximum practical altitude is 28500 meters.

The flight altitude and speed of the two aircraft with turbojet engine are much higher. Among them, the aircraft with TG-001 engine can reach a maximum flight altitude of 3200 meters and a maximum speed of Mach 3.3.

Qiu Shi and others were surprised by the zero speed and altitude. After all, this speed is a real hypersonic aircraft, and it is not a test aircraft or reconnaissance aircraft, but a real fighter.

The No. 16 fighter, which used the tg-002 turbojet engine, brought no surprise but shock to Qiu division.

After all, the thrust of the tg-002 turbojet engine is far from that of the 001 engine. Its single thrust is much higher than that of the TG-001. Therefore, the 16th fighter equipped with this engine can theoretically reach a speed of at least Mach 5, and the maximum ceiling can also reach at least 36000 meters.

Of course, this is only theoretical. In fact, during the test flight, when the maximum speed of the aircraft reached Mach 3.5, division Qiu ordered the test pilots to reduce the speed of the aircraft.

After all, this aircraft is only the transformation of the ordinary No. 16 fighter. Although Wang Bin and Tiangong technology have carried out a series of reinforcement and sprayed high-temperature resistant coatings on this fighter in the transformation process, if the speed of the aircraft rises again, the body and skin of the aircraft will be unbearable.

Because when the speed of the aircraft reaches Mach 3.6, the high-temperature coating on the skin of the aircraft has appeared. If the aircraft is accelerated again, the high-temperature coating of the aircraft is likely to fall off, and the consequence is that the skin of the aircraft will surely melt at the high temperature generated at high speed.

As for the maximum flight altitude, during the test flight, the aircraft once reached a height of 36500 meters, but this altitude is not a practical ceiling, because according to the aircraft record, when the aircraft reached an altitude of 33000 meters, the engine of the aircraft has stopped, because at this altitude, the oxygen concentration contained in the atmosphere is not enough to keep the engine of the aircraft working, So when the plane reaches this altitude, the engine has stopped automatically.
