The result may not be on the street, but the process is a mess.
Since the founding of Tengfei group, a total of six aircraft have crashed, four of which are z-13max tilt rotor aircraft; the two pilots who died were all from this aircraft.
As a result, after the z-13max tilt rotor prototype aircraft was delivered in 1995, four prototype flight test units, the z-13max tilt rotor fleet, were grounded eight times.
If not for Zhuang Jianye's insistence against the pressure, and even willing to invest 60% of the R & D budget in 1996 and 1997 in the z-13max tilt rotor aircraft project, maybe the z-13max tilt rotor aircraft would have died halfway.
In fact, not only did Tengfei group make a big fall in the tilt rotor aircraft, but bell company of the United States also suffered a heavy loss. There is no way to solve this problem. This special type of aircraft, which has both the vertical take-off and landing capability of helicopters and the flight speed of fixed wing aircraft, has adopted many innovative technologies and special concepts, resulting in very immature technology at the initial stage, especially in the vertical landing area The transformation between straight take-off and landing and fixed wing level flight involves the coordination of bearings, flight attitude, fly by wire control, power output and so on. If it is not done well, the aircraft will be destroyed and people will die.
Tengfei group has no previous experience in tilt rotor aircraft. Apart from collecting some public information in this field from Bell company of the United States, the only one that can be used for reference is the mi-30 tilt rotor aircraft designed by Miley Design Bureau of the former Soviet Union in the 1980s.
The problem is that the Miri Design Bureau has completed the initial design and the theoretical calculation of the model wind tunnel. When it wanted to make an equal scale model machine, the Soviet Union smashed to pieces, and even did not have a prototype machine. It is like a neighbor's home decoration design draft. At most, it is a reference. In fact, the significance is not very great.
Therefore, how to do it and how to do it are actually all in the grope of Tengfei group. Because of this, z-13max tilt rotor aircraft has become the most difficult model to develop since the establishment of Tengfei group, and it is also the most invested project.
However, despite the extremely difficult process, the z-13max tilt rotor aircraft is still valued by the army aviation, air force airborne units and the Marine Corps, because the speed and range of the z-13max tilt rotor aircraft alone have nailed the eyes of the three companies to the z-13max tilt rotor aircraft, and they can't pull it out.
You know, in a certain flight test, the z-13max tiltrotor achieved a maximum speed of 498 kmh and a range of 857 km.
This index is twice or even three times that of all kinds of domestic helicopters at present. The problem is that the z-13max tilt rotor aircraft is still a technical verification aircraft, and it is not a really mature train type.
According to the plan of Tengfei group, the zb-225 tilt rotor aircraft developed on the basis of z-13max tilt rotor aircraft will have a maximum speed of 558 kmh, a maximum range of 1760 km, a combat radius of 789 km, a practical lift limit of 8200 m, an internal cabin that can carry 7 tons of cargo or 40 fully armed soldiers, and an external cargo of 5 tons below.
The overall carrying capacity is one level lower than that of the zhi-8plus heavy helicopter. However, the zhi-8plus heavy helicopter carries more loads, but its maximum range is only 725km, and its maximum speed is only 289kmh. The problem is that to achieve such an ideal target, it needs to meet the additional requirements such as no-load, reducing aerodynamic drag and so on.
Otherwise, the zhi-8plus heavy helicopter only has a range of 667 km and a cruising speed of 253 kmh in its daily tasks. Even if it has the ability to refuel in the air, such a range and speed will really affect the rapid mobile deployment of the troops.
In contrast, once the zb-225 tilt rotor aircraft is mature, it will provide a general transport platform with high tactical flexibility for the marine aviation, airborne troops and the Marine Corps. By then, the combat effectiveness of these domestic key rapid reaction forces will be qualitatively improved.
What's more, even if the zb-225 tilt rotor aircraft does not undertake the transportation task of the assault force, its range and speed are no less than that of the light military transport aircraft, and it is also an excellent refitting platform for special aircraft of various services.
For example, electronic warfare aircraft and communication relay command aircraft are the key components of joint operations of Army forces.
In the past, only ordinary helicopters could be used as platforms, and the speed was the second. The key was short legs and the time of staying in the air was limited. If we wanted to fight all-weather, we had to use four to six helicopters to form a fleet and take off continuously and alternately. Only in this way can we meet the basic needs of the division level joint operations.
If the zb-225 tilt rotor aircraft is used, only two will be enough to support all the requirements of this level. Not to mention, it can also meet the construction of the joint operation system at the group and army level in a wider range.
Because the stagnation time of zb-225 tilt rotor aircraft is long enough, the internal space is large enough, and there are enough equipment to be loaded, the application scope is wide enough.
So does the army. The air force also has a different demand for the zb-225 tilt rotor aircraft, which is the rescue of pilots.In the past, when the air force equipment was backward, it was mainly land air defense, and there was no need to rescue pilots behind the enemy lines. However, with the risk of military struggle in the southeast coast increased sharply after the major incident, our army at the attack end had to face this practical problem, especially in recent years, with the upgrading of air force hardware equipment, the air force began to shift from land air defense to both offensive and defensive With the transformation of modern air force, rescuing pilots will become an important task to ensure the combat effectiveness of air force in the future.
For this reason, in recent years, the focus of airborne troops' drills is to break into the enemy's rear with small teams and rescue our army pilots.
However, according to the actual practice of airborne troops, the existing equipment system can not meet the rescue task of pilots behind enemy lines. The main reason is that the distance of the helicopter is close. Once it is beyond Hangzhou, the difficulty of task execution will increase exponentially.
The problem is that the battlefield will never assume that frequent emergencies are the norm. Therefore, an air platform with long range, fast speed, strong concealment, and complex terrain take-off and landing ability has become the dream penetration equipment of airborne troops.
Zb-225 tilt rotor aircraft can meet the needs of airborne troops from any angle, so it has been unanimously recognized and supported by them.
However, compared with the special needs of the army and the air force, the navy is all-round. You should know that the navy has a huge idea of having an aircraft carrier, three amphibious attack ships and four dock landing ships in the 1920s and 1930s. These kinds of ships need all kinds of carrier based aircraft services to form a strong comprehensive combat capability.
Among them, shipborne early warning aircraft, shipborne antisubmarine aircraft, shipborne electronic aircraft, shipborne transport aircraft and shipborne air tanker
This series of special aircraft is naturally well equipped, but the problem is that there is no aircraft in China that can meet the requirements of all the above shipborne aircraft. At this time, the zb-225 tiltrotor aircraft appeared across the sky. From the Navy's point of view, this little Ji Ji is really good. She is suitable for riding the wind and waves and sailing long distances regardless of her body or appearance. What's more, tilting Jackie I want it!
