Wang Bin naturally did not know what happened inside the factory. After all, with their tg-wsx2 engine passing the audit, Tiangong technology began to focus on the trial production and verification of this engine in terms of aeroengine.


    At the same time, in terms of turbojet engine, Wang Bin did not give up to continue the research and development, and after the successful test run of tg-002 turbojet engine, a new turbojet engine launched the research and development work.


    However, different from before, the nozzle diameter of the previous two turbojet engines was only about 60 cm, while the diameter of the newly developed turbojet engine reached 1.2 m.


    This time, they will no longer design a medium-sized turbojet engine, but a large turbojet engine, that is, an engine with a tail nozzle diameter of more than one meter.


    After all, their Tiangong technology will manufacture a large aircraft, that is, the Phoenix aircraft. In addition to using the turbofan engine, they are now developing a prototype, that is, the tg-wsx2 engine, they must also develop a turbojet version.


    However, although Tiangong technology already has TG-001 engine and tg-002 turbofan engine, because these turbojet engines are only medium-sized turbojet engines, the thrust of these engines is still insufficient if they are installed on large aircraft.


    Therefore, if the large aircraft of Tiangong technology wants to meet or exceed the Mach 3 standard, it will not be necessary to use a large turbojet engine for a long time. Of course, if a large ramjet engine can be used, it will be better for a long time. After all, compared with the turbojet engine, the ramjet engine has higher performance in high altitude and high speed.


    Unfortunately, although Tiangong technology has launched R & D work in ramjet, Wang Bin has not provided any technology in ramjet R & D, so until now, they have not developed a qualified ramjet.


    At the same time, in fact, in the research and development of ramjet engine, Professor Zhang and others are not very enthusiastic. After all, Tiangong technology has developed turbojet engine, and its performance is also very excellent. Even in terms of high altitude and high speed, it is no worse than ramjet engine, and in terms of economic benefits, The ramjet engine is far from being compared with the turbojet engine they have developed.


    Therefore, their R & D enthusiasm is naturally not high.


    At the same time, another most important reason is that Tiangong technology is now preparing to develop a turbojet engine with higher power and larger nozzle diameter.


    At this time, the aerospace engine laboratory of Tiangong technology is developing a detonation pulse engine with better high-altitude and high-speed performance than the ramjet. In addition, considerable achievements have been made in the research and development progress. The maximum nozzle diameter of the pulse engine has reached 20 cm. At the same time, in terms of thrust, It can also reach about ten tons.


    It is precisely because the R & D of pulse engine has made considerable achievements that the R & D personnel of Tiangong technology are not active in the R & D of ramjet. After all, these R & D personnel are very busy and have no spare time to develop ramjet.


    Of course, this does not mean that Tiangong technology does not have the strength to develop ramjets. After all, compared with turbofans and turbojet engines with more complex structures, the research and development difficulty of ramjets is much lower. In fact, the most difficult problem in developing ramjets, like pulse engines, is in high temperature resistant materials.


    Even in terms of requirements for material properties, pulse engines have higher requirements. Therefore, since Tiangong technology can develop pulse engines, it is natural to develop ramjets with lower requirements for material properties.


    In fact, not to mention the R & D personnel, in fact, Wang Bin himself is not very interested in the R & D of ramjet. After all, compared with ramjet, the R & D of pulse engine is more difficult, but its future use and R & D potential are definitely not comparable to ramjet.


    Therefore, for Tiangong technology, the key is to develop a usable pulse engine as soon as possible.


    ...................


    Tiangong shipbuilding shipyard under Tiangong technology is the first self-developed new power ship after being taken over by Tiangong technology. After such a long time of construction, it is finally ready to launch.


    Yes, this new power ship is an all electric propulsion electric ship, and this all electric propulsion ship is not an ordinary civil ship, but a police ship, that is, a marine police ship.


    Although the tonnage of this marine police ship is not large, only a mere 1300 tons, and the construction cycle is not long, only a mere less than a year, it took a lot of thought to build this marine police ship for the first time.


    Of course, since it is the first time to build an all electric propulsion ship, it is natural that many problems have been encountered in the construction process. However, these problems encountered in the construction process have finally been solved one by one by the construction technicians and ship designers of the shipyard.


    Of course, like the all electric propulsion technology being tested by the government, the ship manufactured by Wang Bin''s Shipyard also uses medium voltage DC, which is more advanced than medium voltage AC. after all, this ship is an official ship, and the standards naturally adopted should be the same as the official''s own standards.


    At this time, next to the shipyard of the ship to be launched, the person in charge of the shipyard and the shipyard workers are anxiously waiting. After all, there is less than an hour left before the ship is launched.


    But as the boss of Tiangong technology, Wang Bin has not come yet.


    You know, as early as a few days ago, the ship had been manufactured and Wang Bin, the boss of Tiangong technology, had been notified. In the process of notifying Wang Bin, the person in charge of the shipyard personally told Wang Bin that as the boss of the shipyard, I hope Wang Bin can participate in the launching of the first new power recommended ship in their shipyard.


    At the same time, after he told Wang Bin about it, as the boss of Tiangong technology, Wang Bin also promised to come to attend the launching ceremony.


    Of course, they Tiangong shipbuilding. The launch of this new recommendation system marine police ship is not only Wang Bin and the people in their shipyard. In addition to Wang Bin himself and the personnel in the shipyard, they also invited the relevant departments of the marine police in the city and the province, and hope they can send personnel to participate in the launch ceremony.


    At the same time, the official leaders of the city were also notified and invited, hoping that they could also come to participate in the launching ceremony, and these people notified and invited by them basically came at this time.
