Emotions and doubts: The truth about the V-22 frequent fall, where should our aircraft go?
Emotions and doubts: the troubles behind the V-22 frequent fall.
Recently, the V-22 of the US military stationed in Japan crashed again, which makes people question the safety of this aircraft more. V-22, why does it crash so often?Let's take a closer look at this question from an emotional standpoint.
Description of the event: V-22 falls frequently.
This time it was the CV-22B of the US Air Force, which belonged to the 21st Special Operations Squadron. Another aircraft of the same type of aircraft of the same squadron had previously been involved in a crash. In the case of this crash, it is shocking that a week later, the US Air Force and Navy announced the grounding of all V-22s on the same day. This has attracted widespread attention, and the seriousness of the problem is obvious.
The official report said the grounding was due to a "potential equipment failure". This is reminiscent of the "mechanically caused flight accident" that our country has always used, and is this vague statement deliberately evading the truth?Can't we just give a specific reason and tell everyone what went wrong?
The root cause of the distress.
The safety of the V-22 has always been controversial, with a succession of accidents from the very beginning of the test flight. After this incident, the cumulative number of V-22 crashes has reached 20, which is really worrying. Among them, one of the main causes of the accident was the unreliability of the engine-propeller transmission system.
The two sets of propellers of the V-22 are too far apart, and if one fails, it will create a huge yaw moment in level flight. During the take-off and landing phases, this can also lead to a great asymmetry of lift on both sides. Bell's design is to connect two engines to a gearbox in the middle of the wing via a long shaft to deliver power to two sets of propellers. Theoretically, as long as one engine is working, the propeller can be kept running. But the problem is that the reliability of this set of connections and transmissions is not high.
Previous aircraft of similar structures, such as the XC-142 of Walter and the CL-84 of Canada, also crashed because of the same problem. The long axis will also produce huge vibrations when rotating, which will affect the pilot's control feeling, which is undoubtedly a great threat to flight safety.
The danger of the vortex state
In addition to this, the V-22 has the fatal problem of the possibility of entering the so-called "vortex ring" state. In some cases, the downward blowing of the propeller will be carried back to the upper part of the propeller under external influence, which is equivalent to the propeller doing useless work. This situation is easy to happen during the landing or hovering phase, and when it does, the consequences are unimaginable.
On August 5, 2017, a U.S. Marine Corps MV-22 crashed into the sea because the left wing propeller entered a vortex state, killing 3 and injuring 23. This incident also shows us that even if the US military did not declare the incident a crash, it was still a major accident. Compared to the ordinary *** V-22, if it loses power, it is almost impossible to land by spin. This raises questions about the usefulness of such a flying machine.
Contrast and reflection.
In this problem, we can see that even if ordinary *** loses power, the "spin" of the propeller blades can provide a certain amount of lift, thereby slowing down the descent. If the altitude is sufficient, the pilot will operate properly, and the crew will have a better chance of surviving. The V-22 can theoretically also land with spin, but due to its high speed and small rotor diameter, the lift generated by the spin is limited, making it almost impossible to land by spin. At the same time, the V-22 has a relatively small wingspan and is not able to glide for landing like some fixed-wing aircraft.
This contrast makes one wonder if we really need such an aircraft that can neither spin and land like a normal ***, nor glide and land like a fixed-wing aircraft?Our aircraft should be designed to better serve humanity, not to create more safety hazards.
Evaluation and appeal.
There have been accusations about the high cost of construction and use of the V-22, as well as the low attendance of the mission. However, each assessment promoted the merits of the aircraft, and even succeeded in fooling Obama, who was running for ** at the time. Obama himself recalled: "I didn't know how powerful the V-22 was at the time. "This is deeply frustrating and raises doubts about the military's propaganda methods.
But at the same time, why does the US military love the V-22 so much?Indeed, the V-22 is unique in some ways, and its vertical take-off and landing capabilities are unique among today's aircraft. However, its problems and hidden dangers are also obvious. It seems to me that this seemingly contradictory phenomenon shows that our ideas about the development of armaments and aircraft need to be re-examined.
Conclusion and Appeal.
In general, the frequent crashes of the V-22 are cause for concern, and we cannot ignore its merits simply because of its uniqueness. The development of aircraft should focus more on practicality and safety, rather than putting human lives at risk for the sake of showing off. As ordinary people who care about national defense affairs, we have the right to question these issues and have the obligation to make policymakers look at these arms programs more rationally.
On this issue, we must not be deceived by the superficial brilliance, and we must use a more in-depth perspective to examine these so-called advanced **. Only in this way can we meet safer and more efficient military equipment, and truly guarantee that the relevant parties can face up to the problem and take effective measures to ensure that our military's aircraft will not have frequent accidents.
Stand clearly: safety first, choose well.
Looking back at the frequent crashes of the V-22, we can't help but start from the perspective of the Chinese and ask: "Do we really need such a flying machine?""Regardless of the U.S. military's affection for it, we should pay more attention to our own national defense affairs and ensure that the aircraft we choose are not only advanced, but also practical and safe.
The Chinese's position: focus on practicality and safety.
As ordinary Chinese, we are more concerned about China's national defense construction and armament development. Unlike the United States, our position is that practicality comes first and safety comes first. The frequent V-22 crashes make us wonder if we were military decision-makers would choose such a vehicle with obvious safety risks for the sake of showing off
The concept of the development of aircraft in our country.
In recent years, China has made remarkable achievements in the development of aircraft. We have launched a series of advanced ** such as the J-20, which not only have a leading position in technology, but also pay more attention to actual combat capabilities and safety. In contrast, the frequent crashes of the V-22 raise doubts about its usability in real combat.
Advantages of domestic aircraft.
China's domestic aircraft have also made breakthroughs in vertical take-off and landing, high-speed flight, and other aspects. For example, the successful development of the Z-20*** demonstrates our strength in vertical take-off and landing technology. Moreover, the safety of domestic aircraft has been fully considered, and the safety of human lives will not be neglected in pursuit of a certain performance.
Compare the lessons of the V-22.
The lesson of the V-22 tells us that in the development of armaments, we should not blindly pursue flaunting skills and advancement, but should also take into account the practical application and safety of aircraft. We have reason to believe that China's future armament projects will pay more attention to actual combat application and guarantee
Voices of netizens:
On social media, many netizens expressed concern about the frequent crashes of V-22, and many people raised expectations for the development of China's aircraft. Some netizens said: "After reading this news, I believe even more that our country's aircraft will be more reliable and can better protect our soldiers." Someone else sarcastically said: "The V-22 fell more diligently than my faucet, or our plane was strong." "These voices highlight the confidence in our aircraft and the skepticism of the V-22.
The future of the best equipment.
The future of China's leading equipment should be safer and more practical. What we hope to see is not only a technological leap, but also a balance between military science and technology and the safety of people's lives. In this process, we need to persist in seeking truth from facts, deeply learn the lessons of the V-22, and ensure that the development of China's military equipment is more scientific and reliable.
Conclusion & Expectations:
In general, the frequent crashes of the V-22 cause us to think about the choice of armaments. In the eyes of the Chinese, we pay more attention to practicality and safety, rather than just pursuing superficial advancement. It is hoped that in the future, our military equipment can better serve the country and the people, and ensure that our soldiers can fulfill their missions with safe equipment. Safety first, choose wisely.
