Overall, there are many types of jetpacks, ranging from water park entertainment devices to high-end military and personal transportation, and they all have their own characteristics.

Meet the needs of different fields and users. As technology continues to advance, we can expect that jetpacks will have more application scenarios and better performance in the future.

Actually.

Since ancient times, military powers have harbored an ambitious dream: how to give individual soldiers the ability to fly in the air. The realization of this dream will not only completely change the appearance of the battlefield, but also greatly improve the mobility and combat efficiency of soldiers. Among the many studies and attempts, jetpack technology is undoubtedly one of the most eye-catching areas of research.

A jetpack, as the name suggests, is a personal device that allows the wearer to fly through the air by ejecting high-speed jets of air. The development of this device has always been a hot topic in the field of military technology, because it heralds a new way of personal tactical mobility. Imagine if soldiers could fly freely in the air like superheroes, then they would be able to quickly and flexibly adjust their positions and perform various difficult tasks, whether in urban street fighting or in complex mountainous terrain.

The research and development of jet packs involves advanced technologies in multiple fields, including efficient energy systems, precision control systems, and high-strength materials. The integration and innovation of these technologies have gradually moved jetpacks from science fiction fantasies to reality. Although jetpacks have not yet been widely used in actual battlefields, its potential and future possibilities have aroused great interest among military experts and scientific researchers around the world.

With the continuous advancement of technology, the performance of jet packs is constantly improving, and its safety, reliability and endurance are gradually enhanced. Military powers have invested heavily in research in this field, hoping to take the lead in future wars and realize the dream of individual flight. Once jetpack technology matures and is actually applied, it will bring revolutionary changes to modern warfare, and may also affect the civilian field, bringing unprecedented convenience to human daily life.

In fact, the concept of the so-called "personal rocket" is not a product of modern technology, and its history can be traced back to the mid-20th century. As early as 1949, with the rapid development of aerospace technology, the Federation had already begun the research and development of jet packs. This equipment was designed to enable individuals to fly in the air. During that period, people were full of passion and expectations for their dream and exploration of personal flight.

As time passed, by 1967, Federal Bell made an important breakthrough in this field. The company has developed an innovative jetpack that successfully flew during testing, marking a major advance in personal flying devices. This achievement not only demonstrated Bell's technical strength in the aerospace field, but also laid the foundation for the subsequent development of personal flight equipment.

The working principle of the Bell Jetpack is based on a relatively simple chemical reaction.

There are three key substances loaded inside the backpack, which can generate enough thrust when they interact to push a person into the air.

The three substances are: hydrogen peroxide propellant, high-pressure nitrogen, and silver coated with samarium nitrate. As a propellant, hydrogen peroxide decomposes into water and oxygen when in contact with a catalyst, releasing a large amount of energy to generate thrust. High-pressure nitrogen is used to stabilize the injection process and ensure the flight stability of the backpack. The silver surface covered with samarium nitrate acts as a catalyst to accelerate the decomposition reaction of hydrogen peroxide, allowing it to rapidly release energy under control.

Overall, the Bell Jetpack is an important practice in the idea of ​​personal rockets. It not only represents mankind’s pursuit of the dream of free flight, but also demonstrates the innovative spirit and exploration courage of early aerospace technology. Although such devices may seem outdated today, they were undoubtedly a sign of technological progress at the time and provided valuable experience and inspiration for the development of future personal flight technology. In this exciting piece of rocket backpack technology, the designers carefully installed two metal canisters that are fastened side by side to the back of the backpack. Together, the two containers store about 23 liters of propellant, a key substance for rocket backpack flight. When the user of the backpack is ready to initiate flight, they need to perform a simple but crucial action: open the valve.

The opening of the valve is an iconic moment, marking the release of high-pressure nitrogen. These nitrogen gases are compressed to extremely high pressures, and once released, they quickly push the propellant stored in the tank into the catalyst chamber. The catalyst chamber is a specially designed chamber in the rocket backpack whose function is to promote the reaction of propellant and silver material.

In this catalyst chamber, the propellant meets the silver material and a chemical reaction occurs. This reaction produces a high-temperature steam with temperatures as high as 743 degrees Celsius. This steam is under extremely high pressure and is desperately looking for an outlet to convert its immense energy into power.

The release channels of the steam are two carefully designed bends. They start from the top of the metal can, extend along the side of the backpack, and finally lead to the position behind the user's arms. When the steam flows from these two bends at extremely high speed, When ejected from the tube, it generated a huge thrust of more than 1335 Newtons. This thrust is enough to overcome gravity and lift users off the ground for a brief but exciting rocket flight experience.

Throughout the process, the design of the backpack ensures safety and control, allowing the user to not only fly into the sky, but also return safely to the ground after completing the flight.

This rocket backpack technology is an innovative practice of the concept of personal flying devices. It demonstrates mankind's unremitting pursuit of conquering the sky and the infinite possibilities of technology.

Bell's design team creatively conceived a new type of jetpack that they believed would revolutionize the reconnaissance force.

In their vision, soldiers equipped with jetpacks would be able to fly through the air, giving them unprecedented mobility and flexibility on the battlefield. These jet soldiers can easily fly over terrain obstacles and quickly conduct reconnaissance missions in front of the troops. Once they discover the location and movements of enemy troops, they can immediately report intelligence to the commander, helping the commander to formulate more precise and efficient operations. plan.

In addition, Bell also took into account the special operational needs of the Marine Corps

. They imagined that Marines using jetpacks could launch a surprise amphibious assault directly from the coastline during a mission at sea. Or in an emergency, quickly raid the enemy's stronghold, take advantage of high altitude, attack the enemy from behind, and inflict a fatal blow to the enemy.

However, while Bell's jetpack concept sounded very cutting-edge and attractive, it was carefully analyzed by federal experts and policymakers during the subsequent evaluation process. They believe that although jetpacks have great potential in theory, in practice, this equipment has many problems. For example, jetpack endurance, fuel efficiency, flight stability, and operational complexity are all difficult issues that need to be addressed.

In addition, the cost-benefit ratio of jetpacks is also an issue that cannot be ignored. Therefore, after a comprehensive assessment, the Federation believes that, at least at the current stage, jetpacks are not practical as military equipment, and more technical research and development and actual combat testing are needed before their practical application in the military field can be considered.

In the research and development process of military technology, the gap between innovative thinking and practical application sometimes leads to the elimination of certain ideas.

For example, there was once a vision to create soldiers capable of flying in the air. These soldiers would conduct flight operations at an altitude of approximately 10 to 50 meters.

However, this idea was quickly rejected, because flying at this relatively low altitude, the soldiers would be easily discovered by the enemy and become the primary target of enemy fire attacks. At this altitude range, flying soldiers would have little cover to speak of, so their survivability would be significantly reduced, making this concept of flying soldiers unfeasible in practice.

Although the military application of this flying equipment was rejected, in the civilian field, especially in entertainment and performances, this equipment found its stage.

A famous example occurred in 1984. At the opening ceremony of the Los Angeles Olympics that year, the audience witnessed an unforgettable scene.

Several actors carrying jetpacks, like modern versions of "Rocket Man", flew into the venue, and their appearance immediately attracted the attention of everyone present.

The actors soared through the air and demonstrated the power of jetpack technology, leaving a lasting impression on the audience. At this moment, the concept of jetpack entered the public eye for the first time in the image of "Jetman" and became a highlight in the history of the Olympic Games.

The performance not only demonstrated the potential of jetpack technology, but also provided a look at what is possible for future personal flight devices.

Although in the military field, the idea of ​​flying soldiers has been abandoned due to tactical shortcomings, there is still broad room for development of personal flight equipment such as jetpacks in the fields of sports, entertainment and possible civilian rescue.

The future of this equipment may lead to advances in improving safety, efficiency and usability, bringing new flying experiences to humans.
